Not very impressed with these.. The treble is very veiled, midrange is boosted, bass doesn't really have much extension and is boomy. After a bit of EQing they sound ok, but still not good. The clamping power is almost too much, I couldn't see myself wearing them for more than a few minutes. But I am used to my Matrix2's with HM5 velour pads.
The build quality seems very good, they get quite loud without much distortion, and they look great.
I mainly got them because the bundle was nice for $40 (Delta, AP001, HM2, Hengja). The Delta IEM's that were included sound better to me. I think my old HD457's have a more balanced sound. Maybe some burn in will help? I just don't see them changing that much.
