I have one of these. The sound and noise canceling were very good. Unfortunately there seems to be a design flaw that created a weak spot where the ear pieces attach to the headband. After about two years of very light use when flying the headphone broke and really cannot be repaired. You can find many comments around that show that this was not an uncommon occurrence. At this price it may be worth trying but if you can afford the Bose QC-25 it is much better in every way except price. The noise reduction using the Bose is truly amazing.
If you read the reviews across the net, this flaw where the ear piece breaks loose is fairly common. I am NOT trying to cost Woot any sales. I just feel strongly that this kind of information sharing is what these sections are for.
