There are a lot of people out there who swim to keep fit. These folks would probably like to listen to some music while they work out, just as people who work out on dry land like to do. The catch for the swimmer is that water and your typical headphones and PMPs simply don't mix. Those that sweat a lot during workouts in the gym will also tell you that sweat can ruin your headphones. A company called H2O Audio has announced a new set of headphones that can survive in the water called the Surge 2G.
The new Surge 2G headphones are 100% waterproof and can be used up to 12-feet deep. The headphones are also completely resistant to being washed and to heavy sweating. Naturally, you will have to pair these headphones with some sort of waterproof case for your PMP or buy one of the several waterproof players that H2O audio sells. The headphones are designed for bass amplified sound.
The earplugs the headphones use isolate outside noise, help improve the bass, and keep water out of the ears. Each set of headphones ships with five different sizes of elastomer earplugs in XS through XL for a personalized fit. The headphones are tested for water resistance before they ship and you can order a set now for $49.99.
