HD-668 B : amazing sound quality

Build quality could be better but it's good for its price. After falling down a few times, my headphone lost some plastic parts from the bow already but it is still working. Cable and earpads can easily be replaced.

What bothers me most about this headphone is the comfort. The earpads are too small to surround the ears so there is alawys pressure on them which can get annoying after short times already.

As for the sound i was really impressed. It sounds pretty clear and even over all frequencies except vor really low bass maybe. But then again i've never been satisfied with the bass of any headphone.

I never use the included bag because i only use it at home but even if i were to carry it with me i wouldn't use the bag. It's just enough to protect from dirt and scratches but offers no protection against mechanical influences.
