Significant discount for these ones, down from $1099 and free shipping. I guess no one is buying.
From what I gather looking online, fantastic sounding headphones with great noise canceling; however, poor execution with the fans being so close to your ears and the significant weight.

I have a pair of these, agree with the review above. They sound great and are comfortable, great battery life, but pretty heavy. The earcups are pretty chunky too so not the most comfortable to wear on planes etc.
If you can handle the extra $100 (and losing the gimmicky air filter), I'd probably recommend Dyson OnTrac, also on sale for $299 and essentially the same headphones in a smaller package. I recently "upgraded" to the OnTracs and am stoked with them so far.
