Bluetrek is a company that many in the US may not have heard of but still may have encountered their products. About half of their products are re-branded and sold, so your "Verizon" bluetooth earpiece might actually be a Bluetrek. Bluetrek recently released the Crescendo Voice which they claim to be the best in terms of noise cancellation and includes its own applications. The notion of an appstore for a bluetooth headset might seem a little bit odd, but it really makes sense. Not everyone wants to be able to text via bluetooth so why add a menu option if you don't need it? The Crescendo includes Bing's 411 search, several "favorite" contacts, voice recognition, and a state of the art noise cancellation algorithm. Unlike the Jawbone headset, there is no sensor to monitor movement but the cancellation relies upon a proprietary algorithm to mute background noise. It also features "Talk To Me," which is a service that can read text on your phone.
The company promises a 30-50 dB SNR improvement in a loud environment while blocking wind noise. I decided to test their claims in a few different environments. The first was in a quiet room– of course the Crescendo performed effortlessly allowing clear communication between both parties. To ramp it up, I turned on some very loud music. 119 dB to be exact (according to my SPL meter). While this level of noise is dangerous for prolonged exposures, it was a quick test. The other party could hear me, albeit poorly, but this was pretty amazing as I couldn't even hear myself speaking. My final test was driving in a convertible with the top down. The Crescendo again allowed normal communication.
The primary downsides that I found were relatively poor documentation (the menu system wasn't very clear), the Talk 2 Me system costs money monthly (though you get a free trial), and speaker quality was sometimes muffled and uncomfortable. Still, the Crescendo Voice competes very well with the Jawbone line and to be honest, it's almost definitely better at cancellation vs the Jawbone 1. Overall it's a pretty good value if you are exposed to a loud environment when you need to be able to be heard. In the 119 dB test, the loudness of the environment is the limiting factor– not because the person you are communicating with is unable to hear you but because you can hardly hear yourself let alone the other person. If you're thinking about getting a noise-cancelling Bluetooth headset, you should definitely consider the Bluetrek Crescendo Voice.
