I used my Pyle mp3 player while swimming 3 times. The sound quality is excellent, it's easy to control and weighs next to nothing. It easily attaches to the back of my goggles while swimming. The only issue I have is the ear tips that came with the headphones. I didn't like the style of the earbuds as they didn't fit my ears well (constantly falling out). I bought another Pyle pair of headphones with a better fit for me so this was a good workaround.
