Excerpt: I've already passed the advertised battery life and they are still working. I will switch to rechargeable batteries when the one that came with it expires.
Pros: I use a treadmill for an hour each morning. With a regular headphone, I had to keep the volume very high to hear over the noise of the treadmill. With these noise-cancelling headphones, I was able to lower the volume of the TV from about 56-60 all the way down to 20.
Excerpt: I am no audiophile so take this for what it's worth. I was using UE6000s, which are great-sounding but the NC is poor. These destroy the UEs in NC and might sound a little better (wider soundstage). They do not match Bose in NC.
Excerpt: The quality of sound speak for himself. I have tried Beats By Dre and Bose, but the best combination of precise sound and huge noise canceling is present in ATH-ANC9. They still working after battery runs out (but without noise canceling, of course) and the control cable shipped with product works...
Excerpt: I started using ATH-ANC9 QuietPoint to eliminate airplane noise on transatlantic flights. These headphones provide excellent sound quality sound eliminating 95% of jet noise. Most of the time battery lasts over 15 hours which takes care of most of the flights.
Excerpt: I use these headphones at every opportunity I can, which usually means in the office or at home. I listen to indie/alternative rock and EDM, and I think these headphones are versatile enough to provide me with the sound I'm looking for in both genres.
Excerpt: Very comfortable. They goes over entire ear, so they block large chunk of noise just by that. NC is not intrusive. Compare to headphones from company which "makes better sound through marketing" ATH sounds superbly. If you do not want to sacrifice sound quality for NC, this is perfect choice.
