HD-681 Evo BK : Excellent sound, but build quality isn't the best.

The package is good with a lot of accessories, even an extra pair of velvet pads.

The quality of both of the pads (leather and velvet) is very good, they're comfortable and they don't wear easily.

The build quality of the Headphones isn't great, it's all plastic and in some parts not very solid, but with standard-careful use it's not a serious problem.

They can be attached to everything, even mp3 portable players and smartphones, and they sound good.

I use them on a PC sound card, a Sound Blaster Z, and the sound is excellent in all ranges, the mids feel a little thick but aside from that the bass are controlled and the highs are clean, and after some hours of use they don't feel heavy at all.

The price is ridiculous for what you get, they sound even better than some 150-200 euro professional headphones i've tried.
