I have had a chance to play with two of the newer Bluetooth helmet systems to hit the market, the UClear UBC120 (demoed the 100) and the Sena SPH10s. These two units are both state of the art and performed stellarly but there were a few pluses and with each brand.
The UBC100's sound quality is of a very high quality, just what you would expect from a company that designs communication units for military use. The UClear uses the stock ear pieces and do require a but of playing around to get the iR microphone to align (the speakers each have an IR receiver and have to be aligned just right) but once you do, it worked very well. While the Uclear's speakers are internal and very clean in design, the controller is about 2"x1"x1" and had to attach to the helmet. The power and volume controls are rubber covered to protect them from the elements but not very easy to use.

The Sena SPH10s might not be as streamlined in speaker design, it uses their own earpieces that have all the controls integrated with knobs and buttons. the Sena on the other hand uses a earpiece/speaker/microphone combo has you have to remove the stock earpieces on the Giro but on the Smith helmets does take a bit of time because you have to disassemble the headlock control to get the earpieces out (it wraps around the back). The Sena is offered in models designed to work specifically with Giro, Smith and Red.
Both units charge with a supplied USB cable.

USE: The Uclear's best feature is the complete hands free ability to answer the phone. When listening to music, and the phone rings, you will hear a "beep" and the music will pause (not just mute) and all you have to do is say "answer" and the call will be picked up, when you are done with the call, and it ends, the music will pick up where it left off.'s While the Sena does not offer the complete hands free that the UClear does, the ease and access of the buttons is far superior and intuitive than the Uclear's buttons (volume, power, track control). The Sena also works very well with Apples Voice Control of my iPhone 4, I would be interested in seeing how Apple's Siri works. Both of these units to offer an intercom feature when paired with another like unit for quick on hill communication. While I haven't had a chance to test this feature both manufacturers claim a range up to 1000 yards. I am sure that will vary with the terrain of the mountain. I imagine this could be a good feature when on the lift and the other person is on either another chair or gondola/tram.
OVERALL: Both the Sena and Uclear work very well and have exceptional battery life, 2-4 days of daily use without charging. Sound quality of both of these units and top notch and the build quality is exceptional for both. If complete hands free control is what you are looking for, the UClear is the one for you but overall I found the Sena worked better and is overall a better design especially if you are one who is constantly adjusting the volume and accessing music.
Winner: Sena SPH10s
