I have a pair of these and I honestly like them a lot. Previously I used a pair of Sennheiser HD 4.50 BTNC, but the biggest problem with them (and most wireless headphones I assume) is that they simply couldn't play loud enough. And I don't mean unable to play loud enough to cause hearing damage, but unable play louder than normal conversation level if you're listening to songs that were made before the loudness war. With these headphones I haven't gotten close to maxing out the volume no matter what I play. Another thing I find great about these is that they have great sound isolation without the use of ANC, although it's very seal dependent as I notice a large drop in isolation when I'm wearing my glasses, which might explain the difficulty in measuring them. Also you can now use the app SoundID for EQ, although as far as I can tell you can't make your own profile. Instead you can do an A/B test with different kinds of music where the app makes changes to the sound that you vote on before coming up with a final correction. In my case it boosted the bass and the highs which made a big improvement.
