What a pleasant surprise. I was really just looking for some cheaper noise cancelling headphones to wear at work. I use studio headphones and have in my home studio arsenal cans by Shure, Sony, and Beyerdynamic. These Sennheiser HD202's are simply amazing not just for the price point but for the comfort and function. The sound quality is absolutely stellar, even when listening to a 48khz AAC+ web radio stream. And now that I have these, I've noticed them being used in radio studios and being included in condenser microphone package deals. I also like the belt-clipping cable spool that comes with it so you can wind up the non-coiled cord neatly.Haven't used these for studio work as of yet but they do sound comparable to my $200 Beyerdynamic 770's and sound much better than my Sony MD7506 cans. 

Question: What do you think about the sound quality?
Answer: sound much better
