So I bought these because I wanted to sleep and I can't sleep with over ear headphones on a window seat since the moment you put pressure on the bands, it goes haywire(the noise cancellation). These solved that issue.   However, I can only keep them in for 2-3 hours before my ears hurt. I tried both the medium and small tips and it still hurt. So for me, I had to return them. But other than that they are good.   Honestly, if you are buying these for sound, then look elsewhere. Only reason to buy these is for the long flights you have.
