Those New Tracks You’re Listening to Are About to Sound Much Better

SO you’re walking down the street and suddenly the music kicks in, you drop to the ground and pull your earphones out of your ears! “what just happened” you think, then you realise the un-pause on the mp3 has just kicked in and you forgot to turn it down. Well people this will be a problem of the past with these earphones, Now all I need them to do is make coffee. VERY IMPORTAN You can find the original article here

What’s been your favorite set this weekend? Or the best new track you’ve shared with all of your friends? Well take that track and imagine listening to it in exactly the way your ears want you to.

Meet the Even earphones, who tune themselves to each person’s particular hearing. At just under $100, they customize the sounds they play to suit your own audio needs. They use their own EarPrint technology that measures how you hear different frequencies, then sets the earphones to play back sound specifically for each ear. As a result, the headphones give you a profile tuned to your own ear (each ear with its own profile).

One of the biggest things that originally drew me to the earphones was the fact that they are not a pre-order campaign â€" they have physical earbuds available now. The company, who launched in in June, has sold out batches twice thus far and are continuing to take orders on their website. Luckily, I was able to get my hands on a pair to try out as well.

I’m pretty picky about the gadgets I use for audio, as I’m constantly listening to music â€" digging for new sets on Soundcloud, reviewing new tracks, jamming out in my own world. Being able to plug in and listen to my own music is what allows me to focus and, as a result, I’m very specific about the type of earphones or headphones I use. That being said, I was overly ecstatic when I was handed a pair of Even earphones to try out.

First, their appearance: the cords are a high-quality string that have a smooth look and feel. The buds look sleek, with a simple black-and-white color scheme â€" one black, one white, with the EarPrint device hanging at the middle of the cord, meant to dangle at your chest. They don’t tangle easily, which makes them easier to carry without having to worry about dealing with knots. They’re the type of earphones I wouldn’t mind wearing out in public.

Next: the sound test. This is where we meet “Sarah,” the soothing female voice that guides you through a number of sounds to test where your hearing level is at. This test was very straightforward â€" Sarah literally starts by saying “Hi, this is really easy” â€" and felt very conversational as she talked you through each noise. Five pieces of music are played for each ear, and you’re required to hit the button once you hear the sound. Though the process takes a little bit longer than I’d like, it’s seamless.

Overall quality of the listening experience was great. I switched between my Bose over-ear headphones and the Even earphones to test the difference in sound quality and worked to try a few subgenres of electronic music to see how each would sound between both pairs. I started off by listening to Louis The Child’s set from Lollapalooza this year and instantly found that the vocals were much more emphasized than in my Bose headphones. Next, I moved on to Mikey Lion’s live set from Desert Hearts 2016 and loved the emphasis on the bass I was hearing â€" the Even earphones made it much more of an all-around experience. I then switched over to Troyboi’s tracks Do You? and O.G. to continue to test this bass theory and, again, Even delivered.



As my hearing is likely damaged based on the amount of festivals and shows I’ve attended over my lifetime, it was much appreciated that the earphones were able to pick up on the frequencies I have more trouble hearing to create the full experience tracks deserve. Interestingly enough, every time I switched back to my Bose headphones to compare, I had to turn the volume down because it came at full blast and was overwhelming â€" and, when I did, the clarity between vocals and bass was lost. All in all, these babies pack a punch with their sound quality when it comes to electronic music.

It’s refreshing that these earphones don’t require using an app, since that seems so commonplace nowadays. All of the information that goes into your profile is saved in the little box hanging onto the string, so you can plug them into any device â€" phone, laptop, iPod, whatever you want â€" and still have your own profile saved. I found this extremely helpful, as it meant that I don’t have to re-adjust my volume based on what device I’m using. Beyond that, it’s a refreshing change from listening to sets with friends and having to change the volume based on everyone’s sensitivities. It makes listening much simpler and, quite frankly, electronic music better. How could you say no to a custom-made, surround-sound system in your own ears?

To get you started, here a few sets, old and new, you may enjoy listening to in the earphones (ok, to be fair, these are sets that I would want to hear in them):

How Many Walkie-Talkies Can Operate on the Same Channel?

Theoretically, you can use an unlimited amount of walkie-talkies on the same channel (although in practice you might experience a few problems if you took that suggestion literally). Basically, there isn’t really a set limit. You could use as many as you like provided they are set up correctly. Anybody set to the right channel and in range at the time of transmission would then be able to pick up the signal and respond to it.

Most radios have access to 8 channels. These channels each have 38 separate ‘identification tones’. The user sets his/her channel up with the desired tone and then only other users who know the channel/tone will be able to hear the transmissions. As a result, there are, in any given area, about 304 different combinations, so signal interference is unlikely to affect you.

Please do not interpret this answer as saying that your radio has access to 304 possible channels. It does not. It will likely only have access to 8. Some less reputable manufacturers tend to falsely imply access to 304 channels; this is simply not the case. You will have access to 304 possible tone/channel combinations, that’s all.

To better explain the CTCSS codes and how they work; we’ll include a little information from Amherst.co.uk’s FAQ page.

“CTCSS stands for "Continuous Tone Coded Squelch System". These codes are also often called "Privacy codes" If a CTCSS tone is selected; a CTCSS sub-audible tone is transmitted along with the regular voice audio by the transmitting radio. The receiving radio, set to the same CTCSS tone, will only receive audio if it contains that sub-tone. Interference from other users on the same frequency is therefore rejected (unless they are also on the same sub-tone). This is a way of allowing groups of users of walkie-talkies on the same channel to avoid hearing messages from other nearby users”.



So, in conclusion, you can probably use as many walkie-talkies as you like on the same channel. As long as the units in question are of the same type (either VHF or UHF) and have the same CTCSS setup, then you simply shouldn’t have a problem. You also shouldn’t suffer from signal interference due to other users (although you may still experience signal loss/interference/degradation from other sources). We have talked about combating signal loss elsewhere, so please see the other questions if you have any problems in this area.

What Walkie Talkie Channel Do I Need To Use

You may get confused about various types of walkie talkies on sale in the UK, or not be certain what type of walkie talkies you require , and what you’re legally allowed to use in some other countries that you plan to visit, or in your part of the world. Firstly, it is important to have in mind that any type of walkie talkie will function in any part of the world.

A walkie talkie is used on a channel that has a frequency associated with the walkie talkie. In other words, if a channel has a frequency different from that of a walkie talkie, then the two will not work together.

License Free Walkie Talkies

There are 446 license-free frequencies that can be used for leisure radios such as, Motorola talkabout, Binatone and Cobra radios. However, there are eight PMR466 frequencies or PMR466 channels that can be used.

The spacing between each of these frequencies is 12.5 kHz. As the system name suggests, PMR446 frequencies are located around 446MHz and are in the UHF segment of the radio range.

Even though they are not necessarily authorized, PMR446 frequencies are harmonized for use across European countries.



High level use of PMR446 frequencies may result in some annoying problems. However, these can be reduced or rectified by changing the frequency of the PMR446. Other systems such as DCS codes and CTCSS tone can as well help in alleviating the problems.

In view of the possible high use of the frequencies and the PMR446’s unlicensed nature, the scheme is not appropriate for individuals who need to gain access to frequencies at specific times and locations or for life use.

These are simple, short-range walkie talkies that conform to the European Union-wide PMR446 standard and can be used by any person in the United Kingdom or European Union without a license. These types of radios are commonly sold in High-Street shops as well as in most radio outlets.

Commonly known as "PMR446s” radios that meet these standards usually have a power output of 0.5watts, meaning that their range is lower compared to the powerful business walkie talkies that are a licensed and which feature power outputs of 4-5 watts. All of them make use of the same eight channels and this causes problems sometimes if a given area has a lot of radio users using these channels.

Licensed Walkie Talkies

Two Way Radio for Business

Licensed handheld walkie talkies can have a power output of 5 watts, but "license free" PMR446 walkie talkies can only have 0.5watt power output. Therefore, the licensed walkie talkies usually have a better signal penetration and better range in buildings.

A majority of businesses prefer using a licensed 2-way walkie talkie system because, in spite of the benefits of license free walkie talkies (PMR 446), they have some downsides (like lower power, a short range and interference) which make them less effective than licensed business radio systems.

Taxi as well as other transport companies, and large sites like factories or hospitals, and businesses situated in a number of different locations are excellent examples of circumstances where a licensed radio system may be a favored option.

These situations require more powerful radios as opposed to hand-held portable walkie talkies with low frequencies. If the system of your radio relies on vehicle-mounted radios or a base station, a licensed radio system is necessary.

Ofcom

If you want start using a radio system in your business, then you will have to get a license from Ofcom. In other words, Ofcom is a company that controls who can transmit on what frequency and where, to ensure that different users don’t interfere with each other.

Business radio system users range from factories and taxi companies, to industrial sites, hospitals, transport operators and care homes. To begin Ofcom’s licensing process there are a number of requirements that a business must first of all fulfil.

Ofcom license is especially important regarding official radio users like police, military, railways, air traffic control and emergency services, railways, etc. Radio systems that meet specific standards can be used without any license from Ofcom. For many walkie talkie users, license free radios will be okay. And if you are in need of a license, it isn’t that expensive or complicated to get one.

The UK simple license is a license issued by Ofcom and gives holders the right to use more powerful radios. It is effectively a license to use powerful radios any place in the UK, using give frequencies which are shared by anyone using this license. This license is easy and quick to apply for, costs about £75 per organization, and is valid for 5 years.

It is the only option for people who need to use their radio systems anywhere in the United Kingdom, and is ideal for most business radios users.

Geographic License

This license provides you with specific frequencies or frequency allocated just for your organization’s use within a given geographical area. The cost of the license varies from moderately cheap in most locations in the UK (about £100 annually), with the cost heightening in key cities, more so London, where the demand for radio frequencies is very high, going for up to more than £500 per year.

Radios that are designed to use dedicated frequencies such as this, should not be used outside of the licensed area, since the same frequency will possibly have been assigned to somebody else and you will therefore be causing interference to them.

UK Business Radio Suppliers License

This is a license for hire companies and radio equipment suppliers. It allows these companies to do short term radio hire via a set of frequencies allotted to radio hire companies. It also allows these companies to provide ‘demo’ radio systems to potential customers and to undertake repairs to radio systems.

When these companies hire out their radio equipment, it’s hired using this license, so that the person hiring it does need to worry about licensing issues.

Summary

The importance of walkie talkies and radios in the UK and other parts of the world cannot be overlooked. Not only are these gadgets important in everyday communication, but they continue to play a very crucial role in the development of other communication tools. A lot of useful information about radios and walkie talkies has been highlighted in this article for the benefit of radio users and the public in general.

5 Reasons The FBI Hate To Use a Radio Earpiece

When you think of the US Secret Service agents, the image that comes to mind is that of a person in dark sunglasses, black suit, and a coiled tube thing goes into his ear. The coiled tube thing is what the agents use to monitor and communicate what's going around them, where dangers lurk and where they're are needed. Unfortunately, the coiled tube thing tends to be very noticeable such that the bad guys will easily identify the secret service agents. Over the past couple of years, various earpiece companies have closely worked with the US secret service, and have supplied the agents with quality covert tactical earpieces. The covert tactical earpieces are much better than the traditional coiled tube earpieces because of a number of reasons. Some of the reasons include;



1. Discreetness/Covertness

Security professionals typically chose earpieces based on just how discrete/covert they want to be. The level of covertness or discreetness is usually determined by the type of earpiece, earpiece style, and also the color. As aforementioned, if you want to identify a secret service agent you can simply look for the guy with a coiled tube type of earpiece. Luckily for secret service agents, various earpiece companies now offer earpieces which allow the secret service agents to efficiently communicate in a more covert and discreet manner without anybody noticing. They allow for discreet communication between the agent and his or her team.

In-ear earpieces are typically more discreet because they're worn inside of the the ear as compared to the over-the-ear earpieces which are worn outside of the ear. It is also wiser to opt for colourless earpieces as opposed to the coloured earpieces for extra covertness. You can also opt for the wireless earpieces; the wireless earpieces are usually preferred over the wired earpieces since it is hard to tell that somebody is actually wearing the wireless earpiece as compared to the coiled tube, wired earpieces. The wireless earpieces normally receive the signals wireless. One needs to have a separate microphone worn at the end of the sleeve, or even on a lapel. In order to send a message to the other(s), the wearer has to speak into that microphone, and the other(s) will receive the message via their wireless earpieces.

2. Comfort

You should obviously choose an earpiece which is comfortable to wear; Some of the crucial questions to ask prior to choosing an earpiece can include; how easy that earpiece is to not only wear, but also to remove, how easy is it to control and use the earpiece, and also whether the earpiece will be able to remain intact for as long as needed without falling off. One of the main reasons why most people dislike the coiled tube earpieces, is the lack of comfort. Most agents say that the coiled tube earpieces cause a lot of ear fatigue. Most of the secret service agents are usually connected to the radio 12 to 16 hours per day, and some agents will have the earpieces draped over their ears and hanging out, with the volume of their radio turned way up so they do not have to have to plug the coiled tube earpiece in their ears all day long. . Fortunately, the covert/discreet earpieces are very comfortable to wear. They use speakers which are smaller than the average ear canal; this means that there's very little contact, thus are ideal for secret service agents who want to avoid the feeling of ear fatigue.

3. Sound quality

Secret service agents are dealt with protecting the President and as such, it is crucial to get everything right, including the message being sent to their earpiece. In case of a sensitive situation, it is even more crucial to get the message right or correctly. Listening to sounds which are being pushed up a coiled tube may leave a margin for error. The tactical earpieces have the speakers placed in the canal of the ear which means that the sound is basically created there, (approximately 7millimeters from the eardrum), and is worn in both of the ears. This allows the wearer to clearly listen to what's being transmitted through the earpiece, meaning they will be more efficient in their work.

4. Volume

This is one of the main reasons why secret service agents dislike their coiled tube earpieces. Many of the secret service agents say that they usually feel like they are gradually incurring hearing loss especially in the ear which they plug the radio earpiece. Well, with the covert earpieces , the ear isn't plugged so that the sound pressure can get released. And since it's worn in both of the ears, and the speakers are located in the ear, the radio may be turned down, and you will have much better sound clarity. This allows agents to work more efficiently, and in addition, they will have no fear of incurring hearing loss.

5. Localization

The brain is typically wired to locate where sounds/noises originate from, or rather the brain is wired to localize. When you hear a sound from the right side, you will know it since it enters your right ear a little louder and a little quicker, and your brain registers that the sound came from the right direction. This means that a secret service agent, or anybody wearing the coiled tube type of earpiece in their right ear, might hear a similar sound a little louder in their left ear since their right ear is plugged. In sensitive situations, mistaking the location of the sound can be disastrous since it could leave time for bad guys to get away, attack, or complete their objective. The tactical earpieces are designed such that they help the secret service agents to accurately locate the actual place the sound is originating from.

Conclusion

The covert earpieces address all negative issues which anybody who wears or uses the coiled tube type of earpiece experiences. They're comfortable, discreet, they use top notch, high end, high quality speakers which offer the best clarity, they help in reducing the risk of future hearing loss since one can reduce/adjust the radio volume, and they also allow wearers to accurately and quickly localize the direction a sound is coming from.

Intel Made A VR Headset And It's Totally Cord-Free

Intel just announced its own virtual reality headset called Project Alloy, a VR competitor to the Oculus Rift,HTC Vive and the forthcoming PlayStation VR headsets. But what separates the Alloy from the pack is that it’s completely wireless (the wire above is for capturing video for the demo) and it should give you complete spatial awareness without all the dongles the Rift and Vive currently require.

It does this using two of Intel’s RealSense cameras to continuously map your environment. It can even map your hands.

Intel calls the idea “Merged Reality”, essentially combining inputs from cameras around your environment into a virtual world. And Intel was able to pack everything â€" the processor, sensors and controllers â€" into one cord-free headset.



During Intel’s demo, however, the RealSense camera didn’t seem quite as fluid as you’d hope, especially if it’s your primary means of reacting to the digital world around you. Intel says that its hardware will be open source in the second half of 2017 (ugh), so the headset won’t be available anytime soon. Intel is also working with Microsoft so Alloy can run Windows Holographic, the software which powers Hololens, according to Microsoft’s Terry Myerson. Microsoft says that Windows Holographic will also be released in an update for all Windows 10 PCs next year.

The Sepura Group to Provide Communications for the Olympic Games

It’s a brave move by the olympic organisers, the London Olympic communications was run by Riedel and they did an excellent job, they have experience in this field, but the Brazilians are obviously set on using Teltronic and we all hope that they do just as good as a job.

Teltronic, part of the Sepura Group, has been chosen by the public security secretary of Río de Janeiro State in Brazil to supply communications for the Summer Olympics and Paralympics, informally known as Rio 2016.

The €10m contract will cover four venues (Barra da Tijuca, Copacabana, Deodoro and Maracanã), two airports (Rio de Janeiro/Galeão - Antônio Carlos Jobim International and Santos Dumont) and several key transport routes in the Olympic area.

The agreement with Teltronic will see an extension to the traffic capabilities of the existing Teltronic network currently used by the Rio police, as well as the installation of further Nebula base stations to provide additional coverage for the state police and emergency services, and the Olympics organisation workforce.

The existing network was originally provided by Teltronic for the Pan American Games in 2007 and, after some upgrades, is now supporting over 100 dispatch operators and more than 18,000 radios. This new upgrade for the Olympics will feature two extra TETRA carriers for each site, to update the capacity of the existing network; base stations with up to 12 TETRA transceivers to support high traffic loads throughout the event; a CeCoCo Control Centre, to accommodate a further 50 dispatch operators; an additional 6,000 terminals featuring Teltronic's Synchronous Data Manager application to pare down the GPS refresh time in AVL applications; and 24/7 maintenance and operational support during the Games.

"This win builds on our long-term relationship with the Brazilian authorities and public safety agencies," said Paulo Ferrao, the Sepura Group's sales director for Brazil.

"We have a strong background in events of this scale, having supported communications for the FIFA World Cup 2014 and the Pan-American Games, both huge events in the sporting calendar of Brazil and, indeed, the world. We are delighted that Rio de Janeiro's public safety agencies have, once again, placed their trust in us."

Superintendent of critical communications at the Security Secretariat of the State, Colonel Alexandre Corval, commented: "We are extremely happy to have chosen Teltronic.

"The company has been a trustworthy partner to our public safety agencies for over ten years. Once again, they have exceeded our expectations in terms of technical development, quality of the deployment and, above all, their dedication to customer service: throughout the project, they have paid close attention to our technical and operational requirements.

"We are confident that this extension to the existing Teltronic TETRA system will optimise our mission-critical communications, enhancing the security of both visitors and employees throughout Rio 2016."
