Bests & Worsts Reviews from Amazon

I owned a set of Bose Quietcomfort2 headphones for about 2 years. I really loved them, and they lasted about... 2 years. Within months of purchasing them, the plastic arms slowly crumbled, until each sidearm of the set was thickly wrapped in electrician's tape to keep the thing together. Last week, one headphone cup broke off, and no amount of tape would any longer keep them together. I've never traveled with these, I used them only at my desk, I've never dropped them. Even with such care, the plastic slowly crumbled away. Is this planned obsolescence? For something that cost me $350 dollars, I'm very upset. So, I ordered a set of these Audio Technica headphones. So far, they cancel noise slightly better than the Bose, and in fact allow me to go to a lower volume on music while I'm working at my desk. I guess to really compare to the Bose, I'll have to give them a little time and see if they begin crumbling away after just 6 months as the Quietcomfort2 did. So, if that happens, I'll give another review. But for now, I'm happy. UPDATE 09/05/08: I've fixed a few editorial errors on my review pointed out in comments. Also, I wanted to follow through on my promise to give another review: After more than a year of use, these headphones are still going strong without any of the degradation problems I encountered with the Bose set. I still highly recommend these.
