I've had the Bose QC3's for a couple of years and I love them however I have gone through 2 pairs (both have been replaced under warranty). I've probably been unlucky as there doesn't seem to be any wide spread complaints about them not lasting very long, but i'm considering selling the replacement pair that they are going to send me and getting something different, as this pair won't come with any warranty. I don't want any people saying Bose stands for whatever. I don't care what you think about Bose. I really like the headphones and the active noise cancelling is amazing. What i'm looking for is something of a similar design to the Bose and of similar quality. They need to be on ear and preferably have great active noise cancelling. I have been looking at the Bowers & Wilkins p5's. They don't have active noise cancelling but build quality seems to be good and I quite like how they sound (although slightly lacking on the bass). Any recommendations?
