Query: Good, until it broke.

For the price of these headphones, I was expecting more than a month of use before they shorted out on me. Now, the sound ebbs in and out, stuttering as the cord moves. Obviously, I can't use them anymore since the sound quality is so horrible.Before they broke, they were fine. The noise cancellation was OK, but not phenomenal. For the price, if they were still working, I'd say they were fine, but since mine are now kaput, I would not recommend these to anyone.
