I also added nuts with lock-washers to make sure the threads in soft aluminum would be more solid. Manufacturers across the globe now gluing tread to upper. Pic of tear uploaded. They ALL hurt my ear, except this one. EDIT : After contacting the seller, they shipped me another version that work super great! As received, the rubber is so thick that clamping on a regular smooth bar requires a lot of pressure. This is not Arctis Pro and there was no game DAC provided along with the headphones. I was worried that this set would see the return of the headache inducing MSR7 clamp, something that was so severe (to me), that I ended up returning them. I bought these based only on one review that said "These are my happy shoes" and I couldnt agree more! If you value sound and dont mind wearing them for an hour or 2 at a time .
