CyFi is a wireless speaker designed specifically for sporting applications including biking, boating, and camping. Available in two versions, one attaches directly to an Apple iPod and the other features Bluetooth support for providing wireless tunes from any A2DP-enabled device including MP3 players, cell phones and PDAs.

Both versions weigh less than 4 ounces and are designed for easy mountability on a bike handlebar or stem, backpack, or other device. The Bluetooth version also acts as a hands-free speakerphone when used with a phone, allowing you to answer calls while biking, hiking, or other activity and switch back to music after ending the call. The transmitter can broadcast audio up to 30 feet away from the source device, with battery life coming in around 6 hours.

Available in red/black, black/black and silver/black, CyFi is available direct from the web site and at select cycling stores for $149 for the iPod version and $129 for the Bluetooth.
