The right ear recently stopped working. Die Kopfhörer sitzen sehr gut im Ohr. I am certainly glad that I sprung for the Quincys! And then keep falling one by one. Can put a new pair on and do a Day in a theme park, no pain or blisters. My Razer mouse died and I needed a quick budget friendly replacement. No noise canceling. Really want to like them, and they really have great sound, but the fit & finish is just no good for smaller ears. This happens even if the other USB devices in the room are turned off. (you get the point) it Sparks Joy!
