H2O Audio Waterproof iPod Shuffle Case with Waterproof Headphones, Black.

I was hesitant making this purchase as it isn't cheap, but so far I do not regret it at all. I use it one to two times a week and have been doing so for about 8 weeks. I use a hat to keep it in place, winding the wires around my goggles so that they do not drag and I never open it when it is wet. I double check the latch prior to every swim. My resilience has increased greatly and I swim for much longer without being bored, so my fitness has improved too. Music helps with my rhythm and podcasts with the boredom (though words are not as easy to hear).The sound is best when my cap doesn't cover the ear pieces and occasionally one of them will stop working as water has got into my ear. I find this a minor inconvenience when balanced with the increased focus I have.If this breaks, I will need to get another. I can't imagine swimming without it!
