Query: Most impressive.

Not going to write much, as most has been posted on the site, but definitely get these headphones if you're looking in the 50-100 dollar range. Actually these are better than many higher-end(higher-priced)headphones I've tried. Only complaint is that the headphones might be slightly large and heavy - extended use makes for hot ears. Nevertheless,the sound quality is superb. You won't be dissapointed.
