Hallo, ich habe mich sehr über das Headset gefreut, da es nach Herstellerangaben sehr viele Features besitzt und ich endlich ein Raumklangheadset besitzen wollte. Their software rocks, their mouse design rocks, the hardware rocks. I know other companies provide custom sound levels, but this one is very user-friendly, able to modify each ear cuff volume separately, and has a sound test that will automatically create a new sound profile just for your hearing. The roof rack pieces fit perfectly. This bike rack is all that you will ever need. They always fell off. It is blasting from the computer, all the voices, the voices! One 12 pound weight. Im glad to purchase these and HIGHLY recommend to get these pair! No wear shown at all and toe hold still very strong.
