Summary: The battery pack for the noise canceling feature has a clip, but the length of wire between the headphone and the clip isn't long enough for my needs. That said, I've been using it at night to listen to binaural sleep sounds/music. It seems to work well at keeping out other noises, like the trains that run near my house.
Excerpt: The sound quality was fine but it was so uncomfortable and slipped off of my thin fine hair that I returned the item. It clamped very tightly, giving me a headache, and then slipped off if I tried to adjust it.
Excerpt: I don't notice any diff when I click on the noise cancleing button but that doesn't mean it's not working.I think they do a great job at canceling noise either way. My phone has five seperate ring tones so if I need to hear the phone I can find one,and vice-versa.I find them a little clumsy because they fold for easy storage and I don't fly.If your going to be taking them off and on alot you may want to try other head-phones.
Pros: Comfortable, Compact Design, Easy To Use, Great Sound Quality
