The Finis Neptune speaker plays music underwater, solving the problem of how to make swimming lengths more motivating and fun. The speaker clamps just behind the ear and snakes around to the front of the face, resting on the cheekbone. Using vibration properties, the Finis Neptune sends vibrations from the speaker through the swimmer's cheekbones so that they can hear the music. It's such a wacky application of physics that it doesn't seem possible but the Finis Neptune is a fully functional set of speakers.
The Finis Neptune can also store up to 4GB of music, making it a cross between underwater speakers and an iPod. It even has a selection screen that rests on the back of the head while swimming and that can skip or play songs at will.
The Finis Neptune is an awesome invention that will definitely change the swimming experience for thousands of people.
