As a swimmer who loves music, got these for my birthday last fall and they're a dream come true!!! The sound quality is incredible - never imagined I'd be able to listen to tunes so clearly underwater.

The sound is strong and much better than I ever experienced with other waterproof MP3 players. I can really listen to audiobooks and not lose a word even when it’s choppy on the water! I'm very happy with my Sonar Pro and recommend it to all swimmers.

I was skeptical about bone conduction, but DAMN . . . it works great in the water. Out of the water there is an added benefit . . . I ski VERY crowded slopes. You need situational awareness. Unlike earbuds, with these your ears are open . . . so you can hear everything going on around you.

H2O Audio has made a huge difference in my workouts. When I am putting in hours and miles everyday, having headphones gives me motivation, meditation, distraction and tempo for pacing if I choose to swim to the beat. It is by far the best way to manage monotonous laps on long swims!
