This is great - While there are other headphones out there, this has been my overall favorite headphone. I have never had any problems with it, and the sound quality/noise cancelling excel in my opinion. The cord that attaches it to a computer/phone is awesome. I use it when I run, work out, play sports, or want to listen to something but not bother those around me. The headphones does not apply too much pressure to the ears as others have. I received them from a friend as a gift and they have held up for over six months now without a single problem. Sound Quality It is great on sound quality; the sound is played in high definition. Comfort The comfort level is great. Compared to other headphones, it is slightly better than those I have listened with. Design They are designed well, but I can't give much detail here. Durability They are very durable - They have been put to good use for six months without any dip in quality.
