Bose QuietComfort 2

Pros: Awesome sound with any Player (CD, MP3 or plane)

Cons: Pressure in your ear drums....

Summary: Rather expensive headphones. I would like to describe my experience with these cans. First I have to say that if you are looking for a set of headphones and you are considering spending 300+usd you definitely need to go to store and try these out before buying, every brand behaves differenly and you need to decide. This being said, I love the sound and bass it is outstanding and the distortion level is hardly noticeable at a very high volume. I spoke to a rep regarding the very weak parts (the sidebars) and I saw the old model and the new model and according to them the sides are now reinforced and would not break as easy as the previous model. According to them the new model came on Aug 2005 and the there is new material that will withstand more physical abuse. I saw both models and I have to agree with the sales rep. Regarding noise cancelation I had an unexpected test, my girlfriend loves to dry her her hair when I am listening to music, wearing the QC2 I did not even notice she was there until I saw her her hair flying (it was awesome). I have to say that I did try several more inexpensive models that claim high quality but in my opinion these are the best. If you are in the US buy them at 300+usd, if you are in Europe or Latin America you have to pay WAYYYYYYY MOOOORRRREEEE.. in Mexico they are about 450 usd
