I bought a pair of these headphones because I really wanted to see how good they could be and to support this new comer. My experience is pretty much similar to Berger's. I like the build quality. The clamping force on the head isn't that much, which is a good thing. However, it can be a bit too loose. The headphones almost fell out of my head a few times.
About the sound, they sound very similar to my Omega clone. I might be a bit bias, but my Omega clone has just a bit better bass extension.
Overall, I would say that the phones are very nicely built. The headband can use some improvement. The price, IMO, is a bit pricey putting it in a similar price range as the Stax SR007.
