HD-668 B : Great sound, not so great build

I mostly listen to rock from soft to metal, and a little bit of classical music. The sound is very clear, It`s easy to tell the instruments apart. The frequency range is wide and I can hear parts in the songs that I wasn't able to hear with my previous headphones (Marshall Major), along with that when i plug the headphones the the amp and play guitar along to a song i was able to hear both my guitar and the song clearly (They were kind of muffled with the Marshalls).

Of course at this price they have to compensate with something, and that something is build quality and comfort.

Not too say it`s too bad, It`s made of mostly plastic, so not very sturdy. The earpads are a little tough and I can feel a bit of pressure around my ear, but even after long use it doesn't hurt. Also the earpads can be easily replaced with more comfortable ones (There is even an explanation on how to do it in the manual).

The pads at the top are pretty comfortable, but they sometimes get stuck under the the two bows when i put them on, but a little wiggle and its fine, no big deal.

Also in regard to the high Impedance of the drivers, it is still possible to listen through a cellphone for example, but it is noticeably different, especially for the bass, you can hear it struggle.

Overall i would recommend this headphones for home use, and possibly at some point changing the earpads if you will fill it`s necessary
