This is awesome for any serious water lovers! I live in the caribbean so i am constantly in the water. The MP3 player works really well. I have taken it snorkeling and when I do my laps. It it is awesome if you love to swim but get bored in the water. I also use it alot when I do outside work. It is really heavy duty and with the underwater ear buds I can even hear my music when I am mowing the lawn! The only drawback I have found is that if you get water in the earbuds you have to stop and clear them or the sound is muffled. This can mostly be avoided if you have them in before you get in the water. Also if you down more than 6 feet it is also muffled due to water pressure; but hey you can't change that so.. :) Overall great product! I love mine!
