Comfortable earpads (the main reason I bought them), the sound is pretty good, but after an year of sparse usage the right speaker stopped working suddenly. Maybe the cable, which I find horrible (too stiff) has failed somewhere, but it doesn't make a contact at any position of the cable, so might be something else. When buying them, I knew that a non-removable cable is a weakness, but expected them to last longer, so this is a big disappointment. Now I prefer I have bought something else, with a detachable cable, even though not so comfortable.
EDIT: I got them serviced by Thomann for free under warranty. Now they work again, but the cable is still worrisome. The whole repair including the free transportation from and to Bulgaria took 2-3 weeks, which is very reasonable, so kudos to Thomann for this. The repair report was about the cable, and there are no traces of the repair, which is great. On the other hand I requested, if possible to put a jack, and a detachable cable, even if it will not look as stock made, and it was recorded as a desire, but not fulfilled and even not a mention about it, when I was notified that the repair was completed. Of course I understand they might have had technical obstacles doing it.
