BlueAnt Stereo F4 Interphone kit

Your everyday Bluetooth headset is pretty much rendered useless whenever you need to take your bike out for a ride no thanks to the ways helmets fit snugly around your head. BlueAnt has an idea to circumvent this situation with their Stereo F4 Interphone kit which comes with a weatherproof Bluetooth device that is located right outside the helment, featuring a set of thin headphones and a microphone on the inside. It is capable of pairing with up to 8 other Bluetooth devices, letting you make and receive calls on a couple of different handsets while listening to audio directions from your GPS navigation device or even enjoy your favorite tunes while you’re eating up the asphalt at insane speeds. Expect this puppy to retail for $225 when available.
