I have impressed this Kopförer now for 2 months in continuous use and have the price / performance ratio real. Since I have 2 sons who deal not necessarily squeamish with the headphones, and the unit still working properly, you can actually give a 5 star. The sound is more than adequate for gaming and by the bass vibrator which can be switched in 2 levels, it rumbles just right in my favorite games. Every now and then my wife complained that it can quite loud outwardly be. But that is rather mind I always turn the volume to stop. Have the headphones tested the MP3 player and the Operation with batteries you can enjoy the bass vibration to the fullest here. One point deduction, there is still, as I after prolonged wear uncomfortable, feeling the ear schwitziges have.
