After 3 different sennheisers, 2 Sonys and a Shure 530 all broke cause my sweat got in them There is only one earphone I would use to work out with and I will also use it on my DX100 dap. That earphone is the Atrios MG7 which is even better then the JH13.

I had a Sennheiser and a Sony Sport earphone models and both broke after sweat got in them. The Atrios not only can compete with custom made earphones but they cost a lot less and my pair which are over 5 years old fell into a glass of water and they still work. I am a basketball coach and I use them while warming up.
