These headphones are amazing, the sound is really good, the bass is good too. it blocks out all sound which is excellent because it really annoys my mum.
One thing though, when I have the ANR on, and press firmly on the right earphone it begins to make this high pitched squeak. It doesn't bother me that much though because I'm not going to be pressing it like that anyway, but its just a small thing I noticed!
Buy It, Love It!
