The Neptune is a waterproof MP3 player that provides the highest quality sound in the water without the use of ear buds. Neptune uses revolutionary Bone Conduction audio transmission to transmit crystal clear audio through the cheekbones directly into the inner ear. It has 4GB of storage, aquatic athletes can listen to music, audio books, podcasts and more, all with incredible sound quality. The charging cable is included and also allows for quick song upload to the device. The 3-piece design has 2 side speakers and a high contrast OLED screen that sits comfortably on the back of the head. The screen shows the song, artist and play status for each use. Neptune attaches securely to goggle straps and rests on the cheekbones so it does not interfere with swimming technique.
