not seriously dare they sell this stuff all!! no interest passed your way, it serves my kids to listen to the sound of the DSi! it's really not normal to have the right to sell the headphone in a called "pro"! it's cheap, okay, it is offered with the purchase of gear, OK!
I tried to mix with, the result is very disappointing, with an old sony headset orange headphone of an old player I had the same result! I am hard in my opinion? I know, but to tell the truth
