It seems that most of the comments on these are from Brainwavz fanboys or those that got review samples direct from Brainwavz so I thought I would give another voice, although mine doesn't count for much.
I picked up a pair of these for $40 on the Amazon sale and just received them. First impressions: Well balanced overall, bass is full and strong without being overpowering. Decent punch. Reasonably detailed mids and highs. A lot of space for a closed phone and really nice soundstage. There's some sort of frequency peak in the treble that causes quite a bit of sibilance on some material. If you like cymbal crashes, these will be to your liking. We'll see if that calms down after some burn-in time. Overall, a pleasant and very fun sound. They are a more compact design so they are fairly portable (but they do not fold), although not as efficient as other headphones. A portable device will drive it, but the volume will need to be turned up. An amp is probably a good idea.
Comfort is respectable, but not great. Quite a bit of clamp pressure, but not anywhere near headcrushing.They were still wearable with my glasses, but I wouldn't want to wear them for much more than an hour at a time (not nearly as bad as an HD205). Part of the problem is the padding is pretty hard. You don't get much cushion off the stock ear pads.
They seem like they would be pretty durable, although the adjustment mechanism for the cups seem like they would start to be too loose after a while, which would be my primary concern with the design. They just slide loosely on the metal bands, using only friction to hold them in place. The pleather-like material for the pads and earpads is completely low rent. Same type of stuff as on my sub $10 coby's and it reeks of chemicals coming out of the box. I highly think they should take another look at the padding and pleather for this set. They spend a buck more on that stuff and the overall impression of the build quality would skyrocket. The cloth wrapping on the wire that goes through the headband to the right ear is a nice touch. The regular cord is not overly thick, yet not overly thin either, and is quite pliable. Cord is on the short side so not really for home stereo use, but works very well for portable use.
