Boots the Chemist Goes Digital with MOTOTRBO

Boy. The brand new earpiece is magnificent. I mean it is just so stunning so highly developed. I pity people who grew up without the earpiece.

Boots Enjoys Future Proofed Communications in a Single Handset at National Stores Service Centre in Nottingham

Boots the Chemist is the United Kingdom’s leading health and beauty retailer. The company supplies its 2,600 outlets in the UK and Ireland from an 800,000 sq ft Stores Service Centre (SSC) in Nottingham. The SSC stocks thousands of

product lines and is set to handle Boots’ entire range by 2009. It operates 16 hours a day, six days a week and services many stores on an almost daily basis.

Streamlining On-Site Communications in a Time-Critical, Performance-Driven Environment Built on Lean, Efficient Operating Practices
SSC employees were using a number of disparate technologies to communicate with colleagues in their functional group. Engineers, system managers and production line ‘jam busters’ had all set up one-to-one communications systems based largely on DECT or mobile phones to meet their individual needs. Poor coverage in some areas was impacting on voice quality and the ability to reach key people quickly.

In addition to one-to-one communication, group calling was becoming essential to coordinate teams instantly, resolve issues rapidly and maintain the fast order turnaround times and high service standards that Boots stores around the country depend on. The SSC decided to replace its multiple communications systems with a single, integrated solution. Logistics managers evaluated the options

for providing communications for its 140 users and considered implementing a trunked analogue two-way radio system. The team consulted a Motorola Authorised Dealer who proposed a cost-effective conventional digital solution for its wider coverage, improved audio clarity, greater capacity, efficient use of

spectrum and ability to combine a broad range of functions into a single device.

MOTOTRBO Offers Maximum Value for Money with Unrivalled Performance and the Flexibility to Meet the Needs of Multiple User Groups
The SSC selected MOTOTRBO for its comprehensive, scalable, next-generation feature set that would also support its requirements for a lot longer than older analogue technology and make on-site communication between all functions and work groups simple and efficient.

The slightly higher network costs of digital over analogue were compensated by its lower set-up, hardware and licensing overheads. Digital’s ability to provide two slots on a single channel meant that only three MOTOTRBO DR3000 repeaters were required to deliver six talk channels and ensure complete coverage in all buildings and outside areas on the Boots head office complex. The SSC purchased

55 MOTOTRBO DP3600 hand portables and 18 MOTOTRBO DM3600 fixed mobiles for use by its 140 users.

After the radios had been pre-programmed to meet the needs of different work groups, setting up the new solution took just half a day. Users were already familiar with the cell-phone look and feel of the MOTOTRBO handsets, which made training quick and easy. Most staff became confident in the key functions after just 20 minutes training, which helped increase their effectiveness from day one.

MOTOTRBO DP3600 hand portables come complete with UHF antenna, 1300mAh NiMH battery, belt-clip and Impres single unit charger, providing an out-of-the-box solution. The long-life battery means that most Boots SSC employees are able to work 16 hours without the need for recharging. Dustproof, water resistant and subject to accelerated life testing to military standards, in common with all Motorola radios, the DP3600s are resilient enough to withstand the everyday wear and tear of a busy warehouse environment.

The MOTOTRBO DM3600 fixed mobile radios with their plug-and-play functionality are used by desk-based staff such as line managers and function heads. Both hand portable and mobile models benefit from a two-line alphanumeric display, digital calling options, call forwarding, easy-to-use menu keys,

and large volume control knob. Channel switching allows supervisory staff to communicate with all user groups. Five programmable buttons allow users to tailor functionality to streamline communications and have been programmed by DCRS to customise the radios to the SSC’s needs. Three of the buttons are used to provide one-stop hot lines to the warehouse management system control room, the engineers’ help desk and the Engineering Flow controller. A fourth button delivers manual dialling facilities to save users scrolling down the menu list if they know the ID of the radio they are calling. The fifth button is used as a keypad lock to protect against accidental transmission. The SSC’s jam busters, who resolve non-technical faults such as broken pallets and tears in packaging, use the MOTOTRBO radios to communicate across the distribution centre and smooth the flow of goods coming in and out of the SSC. Frequent calls are made by the jam busters but transmission usually lasts for only a few seconds. The team of engineers also has its own channel, which is used to alert colleagues

instantly to equipment problems and ensure machinery breakdowns are fixed before they impact on delivery schedules to the stores. Engineers only communicate when machinery is malfunctioning, which tends of mean that fewer, longer calls are made. The SSC’s information technology managers use the MOTOTRBO hand portables to liaise with each other when monitoring performance of the automated warehouse management solution on the factory floor. Other user groups include controllers, production teams and operations managers.

The six talk channels were configured to match the calling patterns of the different user groups while ensuring maximum availability. Average talk time is five seconds, with a time-out timer after 30 seconds.

Some 60% of the calls are group calls, but the ability to broadcast to all users in a group simultaneously has made a significant impact on response times in a time-critical environment.

Digital Doubles Channel Capacity and Halves Licensing and Hardware Costs while Improved Operating Efficiencies Save Five Man Days Per Week

Choosing digital over analogue has improved channel efficiency by doubling capacity per channel and reduced licensing costs. Hardware costs have also been cut by 50%, while TDMA protocol batteries extend talk time by 40% and enable most users to work two shifts on a single charge. MOTOTRBO’s ease of programming and comprehensive feature set provide the flexibility to accommodate the different communication needs of Boots’ 20 user groups within a single handset.

Reworking day-to-day practices and escalation procedures around the functionality of the MOTOTRBO two-way radio system is already generating significant efficiency benefits. The SSC estimates that it saves five minutes per person per day using the radios, which adds up to almost six hours per day or nearly five man-days each week. These efficiencies have been achieved within only three months of go-live and the SSC anticipates even greater savings in the future.

How Do Noise Cancelling Headphones Work?

The basis of this post is to make you think about what in life is important and what does getting the up-to-date radio earpiece really mean to us

earpieceNoise cancelling headphones are useful to block out noise in noisy environments like trains, buses, and public places.

The technical theory that is worked out is that this device copies the sound waves from outside and then they make these sound waves go out of phase. It can be also compared to that of swimming upstream. If a river’s downstream current is directly proportionate to your upstream swimming strength, then you stay still.

In this case, the device stays quiet!

There are two models of noise cancelling headphones. Over-the -head headphones are a little larger and less compact but the Earbud headphones are compact and can be carried around in your pocket.

There are two types of headphones designed to reduce the interference of the noise that is created in the background. They are the passive noise canceling headphones and the active noise cancelling headphones. Passive noise cancelling headphones work on the theory of muffling the external noise or sound to lessen the interference with music or recorded speech.

Active noise cancelling headphones on the other hand, electronically decrease the external sound and produce a quiet and calm listening environment.

Passive headphones essentially utilize the muffling characteristics that are provided by circum- aural headphones. It is designed like a cup with the rim surrounding the ear. The rim constitutes of high- density foam and sound dampening material. It is soft and doesn’t hurt the ears and it creates an acoustic seal that has the capacity to block 20 decibels of noise.

Active noise cancelling headphones are a more advanced version and have the potential to reduce 20 decibels more noise reduction than the passive model. It uses the phase cancelling technology in its working. This is the main key feature of this model. It works by using a microphone to pick out the external noise which the circum- aural cushions are unable to prevent or block out.

The frequency and the intensity of the external noise are analyzed by the phase canceling circuit and it generates a mirror image of the noise. The noise created is 180 degrees out of phase.

The speaker of the headphones plays the anti-noise along with the music or recorded speech. The artificially generated anti-noise is exactly the opposite of the external noise that has entered the device and so when the two noises meet they cancel out each other. The end result is that the volume of the external noise becomes extinct and the audio you are listening to becomes very clear and audible.

Kenwood Earpieces: Do you Believe?

With such a lot of information on the net about earpiece’s it can be hard to find the best and generally candid articles. here is a piece of writing from a good blog that i believe as factual, do not quote me on it but please read and enjoy

My Girlfriend and I recently started watching ‘The X-Files’ in the evenings.

It all started when my friend Kieran practically begged me to borrow his series 1 box set. He went on and on about it until I eventually acquiesced. When I was little, I was somewhat impressionable and easily upset by TV, so I only saw a handful of first-run X-Files episodes. I remember one where a guy had to eat people’s brains in order to survive, another that featured Golden Age Hollywood ghosts haunting an old film set and a bizarre black and white episode about a deformed character who was in love with Cher.

Watching it as an adult, the series is a lot of fun, not to mention massively addictive. It is easy to see how it became such a worldwide phenomenon. What’s really cool is that I’ve always tended to view movieland’s myriad FBI, CIA and secret agent characters as untrustworthy ‘spooks’ and yet The X-Files portrays them as heroes, relatable, Human and sexy. I kinda like that.

This has made me a little more interested in the idea of getting a Kenwood Earpiece. Beforehand, I can’t say I’d ever really though about it, but after blazing through series 1 of the hit 90’s show (and grabbing series 2 from CEX over the weekend), I’m a lot more interested in getting a hold of one and bumbling about in the dark in search of unexplained phenomena.

The reason I specifically suggested a Kenwood Earpiece, is actually pretty simple. The Kenwood Corporation, operating out of Tokyo, Japan, has been making quality amateur radio gear since 1946. If you’re going to get a radio, or any radio-related peripheral (try saying that one three times fast), then Kenwood is the obvious choice to go with.

Kenwood make earpieces to fit both multi-pin and 2-pin setups, so they’ve got pretty much all your bases covered. Plus, their reputation speaks for itself. If you happen to be involved in some ‘sensitive’ work, then a discreet radio earpiece is easier and less intrusive than lifting a chunky two-way up to your mouth and receiving a loud signal for all around you to hear.

Kenwood’s stuff is professional quality, but equally awesome if all you want to do is don a trench coat, grab a big-ass torch and disappear into the darkness in search of the unknown.

Perhaps you’ll get some messages from the spirit world, who knows? What is certain is that you’ll get a few funny looks, earpiece or no earpiece…

Jabra Wireless headsets Reliable for Office

I write blogs daily to share my views of these Motorola Earpiece. Find out what wisdom, insight and investigation he brings towards the Earpiece marketplace.

audioThe first thing you should consider when selecting a wireless headset is the indication of technological elements used by the wireless headsets to hook up with the cell phone or with the headset base unit that is linked with your cell phone. This choice will impact both variety and protection issues. Wireless technological innovation is used for most cellular phone headsets because almost all mobile phones sold these days have built-in Wireless Bluetooth functions. For workplace headsets, you should choose DECT or Wireless technological innovation.

DECT appears for Digital Enhance Communication Telephony. It is a wireless technological innovation that was presented in European countries and has been implemented all over the world. In the US, DECT uses the 1.9 GHz regularity variety that has been set aside only for speech devices programs. So with DECT technological innovation, you will not experience any disturbance problems with those popular 900 MHz and 2.4 GHz gadgets. DECT 6.0 is not an edition of the technology; it is a marketing term for DECT gadgets produced for use in the US and Canada.

When determining on a wireless headset, the range of the wireless headset is very essential. Given the indication to technological innovation recommended above, DECT is going to have the excellent range. There are several companies out there producing wireless headset and Jabra in one of them in the market. Most Jabra wireless headsets use DECT technological innovation and have a range of 300 ranges or more. This contains the Jabra GN9125 series as well as the Jabra GN9350e and Jabra GN9330e. These wireless headset series are going well in market. The modern Jabra Pro 9470 and Jabra pro 9460 headsets have the best variety available these days, linking successfully for about 450 feet (150 meters).

Another critical feature of Jabra wireless headset is disturbance decrease. For the advantage and comfort of your office communications, you will want to reduce the noise disturbance from your environment. You don’t want to turn the act of having a phone discussion with you into a frustrating task or a listening to test. There are generally three technological innovations in play here. One is disturbance filtering; another is disturbance cancelling; and the third is shouting very loudly. it appears to be that the last is the most used. Noise filtration is part of the digital build and it can be very good. But, disturbance closing is the excellent technological innovation and it is much better at decreasing noise disturbance. Noise closing works by choosing the actual noise and then digitally closing that noise out.

You can usually tell a real disturbance closing micro-phone by the small hole in the micro-phone boom near the micro-phone and usually on the other side from it. This hole is used to ‘retrieve’ the noise atmosphere. Following are some of the best Jabra Wireless headsets which are coming with these great features. The Jabra GN9350e, Jabra GN9330e, and the Jabra GN9125 fold growth headsets are all disturbance closing. With the release of the new Jabra Pro 9470 and Jabra Go 6470 headsets, Jabra has taken disturbance decrease technological innovation to a new level with their Noise Blackout technological innovation which actually uses two microphones.

World of Warcraft Gaming Peripherals

My basic review of a new radio accessory it begins well, looks rather awesome, is easy to run and really energy resourceful, the radio accessory really is a top quality item. I’m happy I purchased it, read more below.

audioWarcraft Gaming GearWorld of Warcraft has grown from a game into a world wide brand. With that success several companies have created new products themed specifically for the world of Azeroth. This list includes everything from headsets to mouse pads and continues to grow everyday. Unfortunately a lot of players in the game are not what I would call “computer people.” Sure they play it on their PC, but they don’t get into the hardware side of things. They just pick it up to enjoy themselves and forget about it later. Some of them have never seen the Warcraft gaming accessories so I have put together a list of what is available.

WOW HeadsetAs pictured above one of the hottest items is the World of Warcraft headset which is manufactured by Creative. It definatley looks like it was forged from the anvil in Ironforge and even sports color changing lenses on each side. Those lenses can also be changed based on your faction or class.
The Warcraft headset comes in both wired and wireless varieties.
Warcraft Legendary MMO MouseNext we have the Legendary MMO Mouse specifically designed for massively multi-player games, specifically Warcraft. It is a wired mouse that obviously sports cataclysmic looks. You can customise the colors with an absurd amount of options and even change how it pulsates.
Gaming wise it has 11 programmable buttons and is designed to fit comfortably in your hand for long raiding sessions. To cap it off you also have the ability to configure your mouse buttons directly in the game. This is much better than messing with the typical driver software and then trying to configure your game to match that.
SteelSeries World of Warcraft Cataclysm MMO Gaming MouseWe have another mouse, the SteelSeries WOW Cataclysm mouse. This mouse has more of a traditional look, which in my opinion matches the headset quite well. The Cataclysm mouse offers 14 programmable buttons and 130 predefined commands to make setting it up a breeze.
WoW MousepadsWhat good is an expensive gaming mouse without a great gaming mouse pad. SteelSeries has also created a few fabulous pads that should fit the likes of any fan. All of their pads are designed to work with any mouse technology and feature a specially textured cloth surface. They currently have a Deathwing, Goblin, and Worgen mouse pads.

Plantronics Bluetooth Headset

The basis of the post is to make you consider what in life is important and what does getting the new radio accessory really signify to people

Bluetooth headsets can be used to provide seamless wireless connectivity to a Bluetooth enabled cell phone or computer. Bluetooth is a fast evolving technology. An average headset provides connectivity within 30ft of the source. Bluetooth 1.1, 1.2 and 2.0 are the most commonly used platforms. Bluetooth 2.0 has backward compatibility with the previous versions and has enhanced data rate up to 3Mbps. For a headset, this translates into uninterrupted conversations and a high quality musical experience.

Plantronics is one of the premier developers of Bluetooth headsets. This manufacturer offers a large catalog of products that are sure to fit any pocket and every requirement.

Plantronics Bluetooth Headset: Safety, Performance and Reliability

Across several states in the US, it is now illegal to use cell phones while driving. However, there is no law prohibiting talking via a Bluetooth hands free system. Plantronics Bluetooth headsets come packed with several features that allow the user to get unparalleled performance even when on the move.

For the high end category, Plantronics has released a product called the Plantronics Voyager PRO. Priced at $110 by its manufacturer, this is probably the best Bluetooth headset in the market today. The product has an active digital signal processing (DSP) unit placed inside it, called the ‘Audio IQ2’. It works by utilizing the Voyager PRO’s two microphones to cancel out ambient noise from the surroundings and help project your voice to the caller. The headset also has a WindSmart microphone screen which shields the microphones from wind noise. Weighing just over 17gms, it guarantees talktime of 6 hours.

Plantronics Explorer 395 is the headset for the mid range buyer. This product has a printed price of $49.99. It has been designed to give a retro feel. Weighing just 0.39 ounces, it is probably the lightest headset in the market. Its keys are arranged in such a way that no matter how you align it, they will still be easily accessible. The only drawback of the headset is its inability to play music or pod casts.

For those of you who want a gadget with style on your ears, the Plantronics Discovery 925 Headset is the one for you. Priced at $149.99, this device is meant for those who want both looks and high end features in their gadgets.

Plantronics Bluetooth Headset: What and Where to Buy

Plantronics headsets come geared with several features to enhance user experience. Prices of the products depend on such features. Thus, before buying any product, it is very important to know what features you need and what you can do without. For instance, if you wish to use your Bluetooth headset for only conversations, then you can do with the Explorer range of products. Luckily, the Plantronics range of products is so vast that you are bound to find one tailor-made to your requirements.

Versatility of Bluetooth Headsets

headset. earphonesHe’s an independent writer based in London, england. His current focus is on all things tech including mobile devices, desktop and laptop computers, software, social networks, Web apps, tech-related legislation and company tech news.

Bluetooth headsets, which were once regarded as high-end accessories, are fast becoming a compulsory accessory for cell phone users. These handsets enable uninterrupted hands-free calling; provided the cell phone is within a certain range and the headset is sufficiently charged. Typically, bluetooth headsets offer 2-10 hours talk-time or 25-250 hours standby.
Benefits of Using Bluetooth Headsets

A Bluetooth headset, due to its wireless nature, enables to multitask and thereby get more things done faster. Other reasons for considering a bluetooth headset purchase are:

* Facilitates easier communication while driving. Talking on the cell phones while driving is deemed illegal in most nations across the world. Regardless of this legal status, using a bluetooth while driving is a safe option. It prevents drivers from being distracted while driving and communicating. It helps them to avoid fatal accidents.
* Enables multiple usage. Bluetooth headsets can be used for several purposes besides cell phone calling, such as VOIP service and land hones. It can be connected with other devices, such as a computer for voice recording or teleconferencing. The greatest benefit of these headsets is that they effortlessly transfer from one device to another without any additional drivers, software or plug-ins.
* Comes with multiple cell phone compatibility. Bluetooth headsets can be used with most bluetooth-equipped cell phones. Therefore, you need not worry about matching your headsets to your phones, or purchasing a new headset if you replace or lose your old cell phone.

Purchasing Bluetooth Headsets: Important Considerations

While purchasing a bluetooth headset, it is important to remember that not all models are alike, some offer greater comfort, while others are more convenient or lightweight. Select from the following basic styles:

* Fits into the ear with an ear bud. These help to block ambient sound, but maybe uncomfortable if worn for several hours.
* Placed with a loop around the ear: These provide greater comfort, but offer lesser security, increasing the chances of the headset coming loose.

You can also opt for a headphone-like headset. These offer the wireless benefits of Bluetooth with the comfort of regular headphones. These may, however, may not be an excellent option if you are a frequent commuter, as they are bulkier to carry around.

Whether you are looking for an elegant design or a sporty look for your bluetooth headset, you can find it all at website The site offers headsets of multiple brands designed for multiple purposes, from noise cancellation bluetooth devices to music stereo headsets.

I recently started watching NASCAR and I was wondering how the drivers communicate with the pit.

The world is stuffed with really awesome, well written articles. If you find one which catches your eye, you have got to post it, well i do! so with authorization of the original author i’ve re-posted this for you to get pleasure from

earpieceNASCAR drivers use a unique radio system that is built in to their crash helmets. These are occasionally customized to suit the individual wearer. In addition to this, there is a push-to-talk button (exactly like the one found on a walkie-talkie), which is situated in the steering wheel. A wiring harness connects the various components together and a separate battery operates the whole thing. The signal is broadcast via a whip antenna that is attached to the roof of the car. In this fashion, NASCAR drivers are able to communicate with pit crews.

In addition to this, most cars are outfitted with a spare Motorola two-way radio that is within easy reach of the driver.

A firm out of Atlanta, Georgia named ‘Racing Radios’ provides the vast majority of the radios used in NASCAR races. Racing Radios have provided equipment to NASCAR races for 30 years or so; they are a trusted firm, creating all the standard NASCAR radio technology and also providing custom radios/peripherals for individual drivers.

According to Racing Radios spokesperson Tony Cornacchia, the majority of NASCAR drivers prefer to buy their own specialized equipment from the firm.

Because so many teams are racing and so many people are working on the race overall, it is not uncommon for NASCAR events to feature 100 FCC licensed radio broadcasts at any given time.

Racing Radios is the company that programs the individual frequencies, not only for drivers and pit crews, but also for staff, officials and security personnel. RR do such a good job, that neither drivers nor pit crews suffer regularly from interference or dead spots. Now that’s something.

According to Terry Boyce of ‘HowStuffWorks’, “Many teams outfit their entire pit and support crews with custom-engineered, hand-built headphones and two-way radios ordered through Racing Radios. Multi-car teams may choose to connect even more people through their radio communications network. Active Noise Reduction (ANR) technology helps to cancel out distracting background noise. Exceptional communication is one of the reasons a 21st century NASCAR pit crew can change four tires and refuel a race car in around 13 seconds — and do it 10 or more times in a single race”.

$100-headphone review What does a Benjamin get you

earpiece$100-headphone review: What does a Benjamin get you?
You might be safe in the knowledge that I bring the top earpiece content pieces, some of which are my very own some of which are curated by me, if i choose to use somebody elses writing it is because it is relevant to my readership, so feel confident you are reading the very best from my industry.

Every type of electronic gadget has pricey, top-of-the-line models that provide phenomenal performance. But most of us have a gadget-shopping sweet spot: We look for the products that make us happy enough that spending more would be a waste.

Though many audio fans tout pricey audiophile headphones that cost hundreds of dollars (or more!), the sweet spot for full-size cans has, over the past decade, gotten less and less expensive. I tested five popular models that you can easily find for under $100, as well as one that competes with them for significantly less, to see what a reasonable budget gets you. All the models I tested use a full-size, closed design. Some are intended for home or studio use, while others include mobile-friendly features. (For more about the different types of headphones, consult our headphone buying guide.)

denon ah d510r over ear headphones
Denons AH-D510R Over-Ear Headphones
Denon AH-D510R Over-Ear Headphones
In the middle of Denons classic full-size headphone lineup sits the $109 AH-D510R Over-Ear Headphones. The earpieces are made of light metal, embossed with the Denon logo, and are suspended from gimbals that have L and R markings engraved in them. The earpieces rotate 90 degrees to lay flat, but the headband itself does not fold. Theres plenty of plastic in the construction, and picking up the headphone doesnt impart a sense of quality.

The AH-D510Rs faux-leather earpads arent especially soft and dont provide much noise isolation, but they fit nicely over the ears and remain comfortable thanks to the light weight of the headphone. The metal headband is covered in a brushed-metal-like plastic with thin, black padding around the top sectionagain, because the headphone is light, this thin padding isnt uncomfortable, and I was able to wear the AH-D510R for extended periods.

A thin, non-coiled cable exits each earpiece, and a three-button, Apple-style inline remote/microphone module sits on the left cable. The remotes buttons are small but easy to find and use by touch, and the inline mic produces better-than-average sound quality, though the output is a bit low.

I didnt find much to like here in terms of sound quality. The AH-D510Rs sound signature is skewed heavily toward bassso much so that the mids and highs, which already sound muted and veiled, get buried. And even the bass has issues: There isnt much definition, and much of the emphasis is in the mid-bass regionresponse tapers off at the lower frequencies. While I admit to being generally critical of the current trend of over-emphasized bass, the AH-D510R all but abandons the upper two thirds of the audible frequency range. Theres also a significant lack of depth in the audio presentation.

Im a pretty big Denon fan, and Ive owned and loved some great Denon equipment, so its difficult to express how disappointed I was by the AH-D510R. It offers sufficient comfort and a decent remote/microphone, but lackluster build, appearance, and sound quality.

house of marley rise up over ear headphones
House of Marleys Rise Up Over Ear Headphones
House of Marley Rise Up Over Ear Headphones
House of Marley offers headphones and audio systems, but also bags and jewelry. The company emphasizes sustainability and earth-friendliness, noting the extensive use of recycled and recyclable materials in its products. The Rise Up Over Ear Headphones exemplifies this corporate philosophy, and despite a $150 MSRP, it regularly sells for $90 or less.

The sustainability message comes through loud and clear even before you open the box, as the packaging shouts its recycled/recyclable nature, looking and feeling like rough, crude cardboard. No extras are included except a unique, semi-rigid carrying case that resembles a small portfolio. The Rise Ups sturdy metal headband is sheathed in a minimally padded canvas cover, and the earpieces are hinged for folding. The Rise Up is available in several designs, including Blue Denim, Camo, Carmel, and Saddle; the Rasta model I tested sported earpieces with a green, yellow, and red canvas covering. The thin, fabric-covered cable on the Rasta version continues the tricolor scheme, but adds black to the striping, and is fairly resistant to tangling and kinking. An inline three-button remote/mic module sits on the cable.

The Rise Up headphone is about average in weight for a full-size headphone, and the earpads are firm with a soft-cloth covering thats comfortable on the ears. The headband is a bit tight, even on my average-sized noggin; the resulting pressure on the ears might make extended listening sessions uncomfortable, though the tight fit does keep the headphone in placea plus for mobile use. Despite the tight fit, sound isolation is only average.

The inline remote is easy to use, with a full-length rocker switch for volume control and a small-but-easy-to-find play/pause/call button in the center. The microphones output level is about average, but the sound quality of the mic is excellent. My only complaint here is that a non-removable cable is an odd compromise on a portable headphone in this price range.

The companys online PR material frequently references House of Marleys signature sound, and a brief listen makes it clear that this audio signature prizes bass above all else. Even at louder volumes, the mids and high frequencies never really make it past the strong bass emphasis. However, that bass is solid and clear, and it extends to the limit of my testing (20 Hz). Soundstage has decent depth, though the highs are muted to the extent that the breadth of the soundstage is compromised. I know there are serious bass fans out there, and the Rise Up offers powerful lows that are much less boomy than you usually find with bass-heavy headphones, but as someone who prefers a more-balanced approach, I personally felt as if there were cotton stuffed in my ears when listening.

The Rise Up is a well-built, apparently environmentally conscious headphone. Its not a headphone for audiophiles or those who prefer balanced sound, but for bass fan who also want to make a fashion statement, The Rise Up is worth a listen.

monoprice premium hi fi dj style over the ear pro headphone 8323
Monoprices Premium Hi-Fi DJ Style Over-the-Ear Pro Headphone
Monoprice Premium Hi-Fi DJ Style Over-the-Ear Pro Headphone (8323)
When you hear the word Monoprice, you probably think of cheap cables. Thats likely to change soon, as the company has been steadily expanding into other electronics markets by using a unique business model: products that are good enough, at prices that are much lower than anyone else. The Premium Hi-Fi DJ Style Over-the-Ear Pro Headphone (8323), which sits at the top of Monoprices full-size headphone lineup, is a prime example. Its a solid headphone that listsbe seated, put down sharp objects, turn off machinery, remove liquids from mouthfor roughly $24. (Monoprices prices change frequently, so you may find that when you visit the product page, the price is $23.51, or $25.17, or $22.84.) More important, the sound and build quality is good enough to include in this group, despite the headphones low cost.

Of course, the packaging of the 8323, as Ill call it from here on out, is minimal: a thin-cardboard box, with the headphones nestled in white, vacuum-formed plastic. (The upside is that theres none of the dreaded hard-clear plastic to cut through.) Included are a 1/8-inch-to-1/4-inch plug adaptor and two non-coiled cables: a thin, three-foot one and a thick, ten-foot one. Neither includes an inline remote/mic module.

Except for the silver Monoprice logo on each earpiece, the MHP-839 is entirely black. The headband and earpieces are made of sturdy plastic, and the ends of the headband are double-hinged, allowing full articulation of the earpieces. The earpieces also swivel horizontally slightly, helping you get a flush fit. Overall, the build quality is solid, and the material appear to be of high quality. In fact, in both appearance and feel, the MHP-839 is quite similar to the Sennheiser HD 280 Pro, below.

The 8323 isnt light, but its about average for headphones of this type, and its pretty comfortable. The earpads are soft, with adequate padding covered in black faux leather. The padded headband provides a good range of adjustability, and its design is unlikely to snag loose hair.

The build of the 8323 is impressive given the price, but its audio value is even more striking: Put simply, no $25 full-size headphone should sound this good. You dont get audiophile-level sound quality, but its far, far better than youd expect at this price. The flaws? The soundstage is flat, and theres a veiled, slightly cardboard coloration to the music. The low end is slightly boosted, giving the 8323 a warm character, though its not enough to upset the overall balance. The mids and high frequencies are pushed a bit to the background, with a corresponding loss in detail. But Im going out of my way to point out the 8323s flaws. For under $25, it sound great, especially at the low end, as bass is full and solid, with all but the lowest octave reproduced faithfully. When fed really low signals (20Hz), the 8323 just steps out of the way and produces no audible distortion.

Not everyone needs (or wants) audiophile-caliber headphonesin fact, most dont. Which means that for most listeners, the 8323 is unquestionably good enough. It doesnt sound as good as the best full-size headphones that squeak in under $100, but the 8323 embarrasses many costing much more. Its also a great option for situations in which potential loss or damage makes using expensive headphones unwise.

Sennheiser HD 280 Pro
Sennheiser has been making audio products since the smoke from World War II cleared, and its established a widely respected name, especially among audiophiles. The companys current lineup includes headphones that range from budget portables to models costing well above $1000. The HD 280 Pro sits at the lower end of that range, but its no cheapie, and the Pro in its name isnt merely marketingthis rugged headphone is equally suitable for home and studio use. It carries a list price of $100 to $150, depending on the current state of the ever-changing Sennheiser website, but its regularly available for for less than $100.

The HD 280 is very sturdy, constructed mostly of a heavy plastic that offers a bit of a soft-touch finish. The design is utilitarian, with little concession to fashion. The earpieces are double-hinged to fold into the headband for portability. The headband is lightly padded and designed to make hair snags unlikely. The soft, well-cushioned earpads fully envelop the ears, and, with help from ample pressure from the headband, offer great sound isolation. (The strong squeeze might bother some, but it should loosen up a bit over time.) Despite the on-ear pressure, the HD 280 Pro is heavy enough to slide a bit if, for example, youre lying on your backor if your dancing gets too exuberant.

The only extra included in the package is a screw-on, 1/8-inch-to-1/4-inch plug adaptor. A long, coiled cable exits the bottom ofand is permanently attached tothe left earpiece. You get no inline remote/mic, befitting the intended home and studio use.

The HD 280 is a great-sounding headphone. Bass is solid, authoritative, and deep, with even extreme lows handled exceptionally well, and theres no bass bleed into the lower midrange. The mids are full, smooth, and natural, with little colorationmale and female voices sound like male and female voices. And high frequencies are crisp, clear, and detailed. The HD 280s studio aspirations are not at all unfounded, as this headphone lets you hear it all.

If I were pressed to criticize the HD 280 Pro, I would say that compared to the excellent bass and treble, the midrange frequencies can seem slightly recessed with some recordings, and theres a slight V-pattern to the HD 280 Pros frequency responsethe extreme highs and lows are slightly emphasized. With certain recordings, or music with emphasized low and high frequencies, listening through the HD 280 Pro might become fatiguing. Nevertheless, the HD 280 delivers all the sound, in precise detail, and its excellent isolation is useful not only in presenting solid bass but also in helping you appreciate a wide, spacious soundstage.

The HD 280 Pro is a great choice if you want to hear everything your recordings have to offer. It has the flat, accurate response and great detail needed by a pro in the studio, with just enough bass and treble emphasis to entertain the consumer. And its built to last.

Shures SRH440 Professional Studio Headphones
Shure SRH440 Professional Studio Headphones
No one involved with audio is unfamiliar with the Shure name, which is synonymous with higher-end in-ear monitors, microphones, and phono cartridges. So I was interested to see what the companys could offer in a serious under-$100 headphone. Slotted near the bottom of Shures headphone lineup, the SRH440 Professional Studio Headphones lists for $125, but has a street price of $99.

The SRH440 sports a simple, conventionalalmost retrodesign, but despite a bit of visible wiring running from the earpieces to the headband, seems solidly made. Much of the headphone is made of plastic, but its high-quality plastic that feels sturdy and is pleasant to the touch. The left and right earpieces are clearly labeled with small, blue and red plastic inserts, and a silver Shure logo is visible on each earpiece.

The earpieces are double-hinged, allowing them to fold into the headband for storage or transport. A nice touch is the capability for the earpieces to rotate in their mounts while maintaining contact with your head. The single-sided cable is terminated in a standard 1/8-inch plug, and though its detachable, the connection to the headphone itself uses a non-standard bayonet mount, which means you wont be able to easily swap the long (and heavy) coiled cable with a shorter straight cable. On the other hand, the cable is reinforced nicely at each endthe spots where cables often fail. The cable doesnt include an inline remote or microphone; the included extras are a 1/8-inch-to-1/4-inch plug adaptor and a soft, faux-leather carrying case.

Ive read complaints claiming that the SRH440 has a tight fit, but my average-size head didnt find that to be an issuefor example, it wasnt tight enough to keep the headphone in place when lying on my back. (My test model was not brand new, so its possible that the fit has loosened up over time.) Partly because I didnt get a tight fit, noise isolation was only average. The replaceable earpads are nicely padded and covered in faux leather, and they fit comfortably over the ears; the headband, on the other hand, offers very little padding. Still, as long as temperatures are low, the headphone is comfortable for long listening sessionsas with many headphones of this type, and especially those with pleather earpads, your ears will get warm after a while.

Like the HD 280 Pro, the SRH440 is a great-sounding headphone. Its audio output is flat and accurate with full, solid bass thats well-defined with absolutely no bleeding into the midrange. The low frequencies are solid down to 20 Hz, without the over-emphasized low-frequency bump that bassheads crave (and, sadly, that many consumers have come to accept as normal). What I really like is the way the SRH440 plays the lower midrange strongly and cleanly but without a hint of bass until real bass is present in the recording, when it comes through appropriately. The midrange is also smooth and even, and highs also are clear and detailed, blending well for a very balanced presentation.

Soundstage is about average, with great left-right placement but not a lot of depthnot a surprise in this price range. One criticism (which for some people might be a strength) is that the overall sound character can seem overly subduedwhereas the HD 280 Pro presents a much more immediate, dynamic impact, the SRH440 is more laid back. Nevertheless, this is a very minor criticism of a very good sounding headphone. Its neutral-but-relaxed character makes it great for long listening sessions.

Overall, the SRH440s solid construction and cabling mean that it should hold up over time, and its accurate, neutral sound wont lose its appeal. At this price, its a steal.

Sonys MDR-7506 Professional Headphones enjoys almost mythical status among headphone geeks, as its been on the market since 1991 and has earned a reputation among professionals and amateurs alike as an audio workhorse. (The MDR-7506 is externally similar to Sonys MDR-V6; at times, its apparently been internally identical, as well, but that doesnt seem to be the case currently.) The MDR-7506 lists for $130, but commonly sells for under $80.

Befitting its age, the MDR-7506 is a conventionally designed headphone thats survived long enough to seem retro. The headband is metal, sheathed in what looks and feels like real leather, and lightly padded. Red and blue plastic inserts in the headband make identifying left and right sides easy, and the earpieces are double-hinged to fold nicely into the headband for storage or transport. Small wires are visible running from the earpieces to the headband, as are a few screws fastening the plastic and metal bits together. Beautiful it is not, but it truly looks like what youd imagine a studio-monitor headphone to be. The long, coiled cable is not removable, nor does it include an inline remote or microphone. Included are a faux-leather carrying pouch and a threaded, 1/8-inch-to-1/4-inch plug adaptor.

The easily replaceable, pleather-covered oval ear pads are soft and comfortable, though as with the Shure model above, your ears will heat up after a while. (Velour earpads, available from third-party vendors, improve the 7506s comfort dramatically.) The headband pressure is a little on the high side, but that pressure makes for a good seal and good sound isolationand it does loosen up over time. Since the MDR-7506 is a bit lighter than most headphones of this size, it stays securely on your head without squeezing too much. Heat aside, this is a headphone that can be comfortably worn for long sessions.

The MDR-7506 is a great-sounding headphone. Solid bass extends cleanly to 20 Hz while never creeping into the lower midrange. The midrange itself is clear and natural, and the detailed, crisp highs bring out nuances in your music that you might not have heard before. Soundstage and instrument placement are very good, though better left to right than front to back.

Best of all, there is no buttheres a reason this guy has been around more than twenty years. Its of course not perfectthe design is ancient, in summer your ears will quickly sweat if you havent swapped out the earpads, the soundstage is merely good, and Id love to see a replaceable cablebut the MDR-7506 will shame headphones several times its price. When asked, this is the full-size headphone I recommend most frequently.

Buying advice
While this article began with the premise of reaping the benefits of trickle-down technology, its remarkable that among the best headphones in the group is one that dates back to 1991. That doesnt completely invalidate the hypothesis, however, as the $25 Monoprice 8323 is a truly astounding bargainits difficult to reconcile this kind of quality with such a low price. The Denon and House of Marley headphones, on the other hand, miss the mark, plain and simple.

As for the remaining three, whats noteworthy is not only how very good each is, but also how similar they are to each other. Each comes in relatively plain packaging, and the design of each is decidedly old school studioalmost enough to be retro hip. But what you give up in looks you reap in sound quality, build quality, and comfort. The Shure SRH440 has an unobtrusive, reserved output thats reminiscent of what was once called the New England Sound of speakers from makers such as KEF, KLH, and Advent. Sennheisers HD 280 Pro spices things up a little, with a more dramatic soundstage, more kick to the bass, and more sparkle in the highs. It sounds great, but if the audio engineer mixing your music has also kicked up the bass and highs, you may end up with too much of a good thing. Sonys MDR7506, in my opinion, gets it right.

But the truth is that when it comes to sound quality, the Shure, Sennheiser, and Sony models are very similar to each otherand all very, very good. Unless youre a perfectionist audiophile (and we know who we are), theres a good chance that $100 really is the sweet spot for full-size headphones. And if even thats too much for your wallet, the Monoprice 8323 is astonishingly close behind, making it the clear winner in terms of value.

Walkie Talkies – An Overview

I don’t know if you came here because you read it on social media, twitter, facebook, google +, stumble upon or somewhere else. But thank you for coming and I trust you like reading this as much as I did.

Walkie talkies are unique in that the half-duplex channel they operate on will only allow one radio to transmit at any time, though there are no limits to the amount that can listen.
Rather than have an earpiece similar to a telephone, they have a built in speaker so the unit does not have to be held to the ear. They are used to connect to both other handheld units and to radio stations which are in a fixed location. The typical shape is of a large telephone handset, with a fixed antenna poking out of the top of the unit.

History
The fist radio audio transmitter and receiver that was coined the ‘walkie talkie’ was created by Motorola. The group involved created the Motorola SCR-300 using frequency modulation. This first revision was actually backpack mounted. Not long afterward, during World War 2, Motorola produced the ‘Handie Talkie’ which rather confusingly is what we would now recognise as a ‘Walkie Talkie’.

It had massively reduced performance, but was the first completely self contained handheld device.
Nowadays
They are widely used nowadays in both consumer and commercial environments, for example outdoor recreations, business use, military and public safety. As a result of this the prices and quality of the units vary greatly, from kids walkie talkies to rugged digital units for heavy industry use.

As technology has improved, and reduce in size, so have the housings. Normally, you will find the commercial walkie talkies are tougher, in protective cases and limited to a select few frequencies. Consumer versions on the other hand tend to be smaller, more lightweight and capable of scanning across far more channels within the band.

Kids walkie talkies are generally low power units, and as a result are exempt from licence requirements. Though they often look the same as fully featured versions, they are normally relatively low-tech in comparison.
