Description from the website:
Rugged Waterproof Headphones
The Rhinoceros has always been revered as a tough, and seemingly indestructible animal. With tough, thick skin it survives some of harshest conditions on our planet. Just like the animal, the Rhinos are built tough. Made to withstand some of the harshest punishments, the Rhinos just keep chugging along providing hours of audio ecstasy. Water and headphones don't mix, until now. The Rhinos can be rained on, splashed on, dunked in water, and they even float. After dunking them in water, just shake off the excess water and go back to listening to those self-help tapes on how not to drop stuff in water.
40mm drivers deliver the full range of clear sound, wirelessly.

External controls allow you to adjust volume, change tracks, play/pause, and answer calls.
