I got mine yesterday, open box from Monoprice. I submitted for a RMA replacement for a couple reasons. The gimbal screw was loose on one side and scraping the cup/housing. I was able to tighten that myself, but it was a little tough given the placement. The second problem was the jack oh the other cup. It seems a little loose, and the sound on that side would cut out on the stock cables. With some wiggling/twisting it can come back in, but that's not something I can live with.
Playing with the gimbal screw and jack really demonstrated the free movement of the cups all over the place! I thought the pads we're comfy and a little warm after a while. The headband would be the trouble spot if any - as others have said.
If the replacement has any issues, it will make my decision between the M1060c and 1MORE triple driver over-ear a little easier.
