I also recommend using the Waterproof MP3 player from SEWOBYE with these as well for the best experience in listening to music while you swim

The sound is great and I have found that the fit, while using the recommended "fitgoo", is just perfect for a really enjoyable swimming experience

Customer service quickly sent a new pair as soon as I contacted them; another 5 stars for a hassle free experience

I don't know if they sound better -- but since I am not fighting with water in my ears -- the experience is far superior to anything else :)I don't know why it's so hard for most earbuds to get this part right

I primarily listen to classical music and having Chopin's Nocturnes or Brahms' piano concertos playing in my ears while swimming can be quite a blissful experience and it actually encourages me to swim longer and with more energy

Finally I am close to a seamless audio experience, and can listen to podcasts and books while I swim..
