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-part 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 the goggle straps so it rests on the cheekbones for a comfortable, contoured fit. A streamlined interface offers four buttons for easily navigating between music, podcasts, audiobooks, and other supported audio files.

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