Ideal for:

Loud, noisy environments – planes, trains, buses, work or dorms.

Best Purchase Nice noise cancelling, good voice quality, easy to fold/wrap. Easy to carry. Overall very nice value & good product January 25, 2013
good earphones good set of earphones really not much you can say except that they work well and keep backround noise around you to a minimum, also super fast shipping. August 22, 2011
Good buy I wanted a lightweight, comfortable set of head phones for my laptop. These headphones fit that bill very well at a reasonable price . Good quality sound. Slight hiss when used without sound input, and the noise canceling is ineffective. But they fit my bill very well and I am pleased with the purchase. June 2, 2011
