These 'phones are incredible. I paid far more than the 179 that Play are selling these for and at that price you are getting Bose/Denon beating headphones. The noise cancelling element has made some recent longhaul flights very easy. I have read some negative reviews of these but I can't really see what people are complaining about. There is a comment I have noted that the Bass isn't ealistic enough. I am an audiphile and I can tell you the Bass handles perfectly. I have an eclectic music taste from bands like pearl Jam all the way to Massive Attack. The ultimate test is listening to Massive attack "angel" on these and you will not be dissapointed.
Price wise, 179 for a pair of headphones which I think are worth almost more than this. Build qualiy is second to one, I used my on some fairly rough terrain and dropped them a couple of times with no damage and no scratches! A very light and comfortable set of true digital 'phones for a great price.
In my humble opinion, you can't go wrong with these!
