I have been using these for a couple of weeks and I am quite satisfied, at least with the sound and comfort.
But from the first days I started get sound interruptions. I listen to a music, game or video and suddenly..silence.. or sometimes I get a small amount of sound. I don't even move and it can be very annoying.
I tested both cables and the issue is still there. I think it is somethimg that doesn't make good contact between cable and headphones.
In some cases I just shake my head and the sound is back, but some other times I have to move the cable to another position.
Overall, these headphones are very comfortable. I can use them for hours with no problem. The sound is good.. When they work.
