The Duo™ is an MP3 player designed for swimmers that delivers the highest quality sound without the use of headphones. The Duo™ uses a sleek two-piece design and bone conduction audio transmission to deliver crystal clear sound through the cheekbones to the inner ear.

An integrated clip design secures the Duo™ to eyeglass straps so it rests on the cheekbones for a comfortable, contoured fit. A simplified interface offers four buttons to easily navigate between music, podcasts, audiobooks and other supported audio files.

The Duo™ supports unprotected MP3 and WMA files. The included USB magnetic dock allows for data transfers and universal charging. The device offers 4GB of flash memory and a rechargeable lithium-ion battery life of up to 7 hours.
