By receiving this article three months ago, I discovered at the opening of the box a defect on the coating of the left ear: the flap of leatherette had not been stuck inside the receiver (side facing the outside of the helmet). No big deal, I kept it. Three months later, I use the headset overnight. I ask him. The next morning, I see a breakout across a plastic bows. After handling the fracture gets worse and I end up with two pieces in hands. In short, bad design headphones: brittle plastic, self-breaking. Unable to repair (Super Glue + scotch changed nothing). Avoid.
