I really like the sound quality on these. They have the MySound app that goes with them and gives you a lot of options on customization that I have never had on any headphones I had before. My sound preferences are probably different than other people's (I like a lot of bass)...but the app fixes that issue as you can change it to however you personally like the sound on your headphones, more bass, no problem! I also use them to listen to audio books on my phone sometimes and there is also an audio book option!
