The IWCE was a great event this year, with lots of great companies and exhibitors. Particular noted showcase's were Pryme and their new Bluetooth range. You can find the original source of the article on this websiteÂ
Pryme Radio Products recently showcased four accessories that leverage Bluetooth technology as the California-based manufacturer continues to expand its product portfolio supporting both two-way-radio and cellular users.
Introduced at IWCE 2015, Pryme Radio Productsâ new BTH-600 is a heavy-duty Bluetooth wireless speaker microphone that supports push-to-talk (PTT) capability on two-way radios, according to Pryme Radio Products President Dave George. By loading different software into the headset, the user can utilize PTT applications that are available on cellular phone, he said.
Based on Prymeâs Storm Trooper platform, the BTH-600 is waterproof and utilizes an off-the-shelf, rechargeable cell-phone battery, George said.
âOne of the coolest things about it is that itâs got a big batteryâ"it can run for 40 hours of continuous duty on a single charge, and it can be in standby mode for 30 days,â George said during an interview with IWCEâs Urgent Communications. â
The BTH-300 is a small, lightweight clip-on box that converts any wired Apple iPhone accessory into a Bluetooth headset, according to company literature. Featuring 10 hours of battery life, a built-in PTT switch and a built-in noise-canceling microphone, the BTH-300 can be used during covert operationsâ"there is no visible LED lightâ"and supports both radio and cellular communications, George said.
âThis will work both with radio dongles and with cell phones at the same time,â he said. âIt has a separate button on it for answering phone calls, and it has technology inside of it that will allow you to prioritize whether you want to ignore the two-way-radio calls while you are on you cell phone, or whether you want to ignore the cell phone calls when you are on a two-way-radio call.â
For those using Motorola Solutionsâ XPR-3300/3500 series radios on a MOTOTRBO network, Pryme Radio Products has developed the BT-M11, which is a Bluetooth adapter that attaches directly to the radio with a patent-pending locking mechanism, George said. Previously, Bluetooth chips were so large that Prymeâs Bluetooth adapter had to be attached with a cable, he said.
âNow that the Bluetooth chips have gotten much smaller, weâre finally able to get it inside the small connector,â George said. âSo, weâve designed a new small connector that will attach directly to the side of the radio and contain the Bluetooth technology.â

Clinton Portrait Shows Famous Liar
Presidential portrait artist Nelson Shanks has revealed that he incorporated a hidden message into his painting of former US President Bill Clinton.
In an interview with the Philadelphia Daily News, the artist told the world (well, Philadelphia) that a curiously long shadow, apparently cast by the plant next to the Prez, was, in fact, cast by a mannequin in a blue dress that he had in his studio at the time he painted the portrait.
According to Mr. Shanks, he did this as an allusion to Clintonâs famous affair with White House Intern Monica Lewinski, the woman who famously, um, relieved The Presidentâs stress levels - before using her highly prized oral skills to catapult herself into a career in shit telly, low-level celebrity and (I kid you not) fashion design.
âHave the same handbag that I put down on the Oval Office couch in order to sexually service our nationâs president! Just $9.99â the ad copy (probably) says, as the glass ceiling lowers to the point that it actually constricts the breathing of female professionals the world over.
The worst of it was that, although Iâll grant you that Monika was better looking than Hillary, she was still a bit of a minger.
Aaaaaanyway, getting back to the point somewhat, the inclusion of the blue dress hints at the DNA evidence (and I flat-out am not saying what kind of âevidenceâ, but Iâll pretend it was âspitâ. Hell, maybe it was!) that was famously left on Lewinskiâs blue dress. Basically, Shanks was trying to make a point about âthe shadowâ that Clinton cast on the office of President. Or something.
Eventually, after famously denying that he had enjoyed âsexual relations with that woman, Miss Lewinskiâ (possibly as much ashamed of her slightly minging appearance as the fact that heâd lied to the Nation), Clinton was forced to fess up, and Americaâs right-wing press had a field day.
Therefore, according to Mr. Shanks, Bill Clinton is âprobably the most famous liar of all timeâ.
Apparently, Mr. Shanks was knocked quite severely on the head and was completely unconscious for the 8 f*cking years that George W. Bush treated America (and the rest of the world) like his own personal nymphomaniac intern.
During the course of this era of idiocy, Bush openly lied about âsecuring weapons of mass destruction in Iraqâ and then used said disinformation to lead an illegal invasion/occupation of another country.
Oh yeah, he also rigged an election, too (probably).
Now, perhaps I should cut Mr. Shanks some slack, I mean, after all, during Bushâs reign of terror, Dubya could have been shagging every White House intern in the damned building five times a night, but nobody could tell because he was there were too many bombs whizzing about in a war that cost TWO TRILLION DOLLARS and resulted in 174,000 dead Iraqis (with 123,000 of that number being innocent civilians whose only crime was that they lived in Iraq), just so he could earn a bit of extra bank for his dadâs golf buddies.
So yeah, nicely done.
Now, Iâm not defending Clinton for scoring a BJ outside the confines of his marriage (however, if even half the stuff Iâve heard about marriage is true, then thatâs the only place he was likely to find one!), Iâm just saying that Clintonâs âdark shadowâ concerned an extra marital affair, the worst consequence of which was the rise of Monica Lewinski as a quasi-celebrity â" his wife didnât even chuck him over it. Whereas, if weâre playing the âblame gameâ here, his successorâs portrait should feature him snorting cocaine off of a Guantanamo prisoner and wiping his arse with the US flag, whilst at the same time dancing naked atop an oil tower crudely fashioned from hundreds of dead Iraqi civilians. Thatâs all.

How Do Passive Noise Cancelling Headphones Work
It is quite unfortunate that for most music lovers, there is a myriad of ambient noises and sounds that can really interfere with the music coming from your earphones, Now, if you have ever once tried to listen to music on a bus, train or airplane, then you are intimately familiar with this problem. The engine's roar and/or the incessant chatter from fellow passengers, make extremely hard to hear the sounds coming from your speakers, even if they are on or inside your ear. Fortunately, to combat this dilemma, innovators have come up with far more enjoyable way of listening to your music- Noise canceling headphones of which there are two types:
- the active- the passive types.
HOW PASSIVE NOISE CANCELLATION WORKS
The simplest type of noise cancellation is the passive noise reduction, sometimes called noise isolation. From a technical perspective, just about any kind of earphones are able to provide some degree of passive noise reduction (though some are designed for it more than others). This is mostly as a result of the materials used to make the headphones which block out particular sound waves, mostly those of a higher frequency. The absolute best type of passive noise canceling headphones are however the circum-aural types which are specifically engineered to maximize the amount of noise it filters. We will take a look at this some more in a bit. Essentially, where passive noise isolation, the head phones are so designed that they will fit snugly into or around each ear. This makes it significantly harder for noise to escape and bother others in your immediate environment, and it also prevents the noise in your environment from making it hard for you to listen to your music. Passive noise cancellation earphones tend to have very large ear pieces, with large pieces of foam wrapped around them. You need to squeeze the foam into your ear which them provides a perfect seal for the ear canal, or they fit just right around your ear.
All this is saying that passive noise cancelling earphones in essence imitate what happens when you choose to cover your ears with your hands or put some ear plugs in. The excess padding is always done with materials that naturally act as sound barriers- fitting into your ear and sealing off the ambient noise.
Supra-aural headphones, which are earphones placed over and around the ear, instead of in or around it, are probably the very worst at any form of sound cancellation. They tend to be low density, small and very light, as such there is really not much padding to block and outside sound or ambient noise from entering the ear. Furthermore, because they are only placed on the ear, there is a great deal of space for any external noise to travel around them and into the ear canal. It is on very rare occasions that you actually find a top quality supra-aural earphone, because they are simply unable to provide the kind of noise cancellation that circumaural or in ear headphones provide. Supra-aural earphones are lightly manufactured and as such are usually marketed for customers who are not particularly focused on headphone quality, but mostly looking for basic functionality.
Take for instance, most desktop or video game headsets tend to be supra-aural. They are mostly preferred because they are light and as such are suitable for the long, extended hours they will be used. Additionally, in cases like these audio quality is not of great importance since it they are mostly used for spoken communication, where clarity is the focus and nothing else really matters.
When it comes to passive noise cancelling headphones, circumaural or around the ear headphones provide a significantly better noise cancellation quality. They are bigger in size and as such they include more noise reduction material. This in turn creates a far better buffer against outside noise- think beats headphones. Essentially this means that they are heavily packed with layers of high top quality high density foam,, or some other sound absorbing material. Admittedly, this then makes them a bit heavier than the average headphones, but since they completely block the ear off, they keep out up to 95% of outside noise. Well, this is assuming that the circumaural earphones you choose, fit your ears snugly. If they are either poorly designed or not the perfect fit then ambient noise will still be able to make its way in.
