The headphones proves good sound quality even without the USB device. In particular, the space is extremely good. In Dolby mode, the sound picture moves so far away from the head, that I looked more to me if something else happened behind me ... Unfortunately, the microphone without USB sound card is not powerful enough, the sound is still very good, whether. to an entertainment system or digital piano The Dolby effect is spatially extremely good but also somewhat artificial. But what, even in good THX cinema often. One should test the sound quality with high-quality sound sources, ie WAV, FLAC or HD video. Look for games and movies, the sound is fantastic, as pure music headphones still ok, especially because of the spaciousness. Who wants to hear the other hand, in poor quality much mp3, should take another handset, the 'Beautify' the sound artificial.
Clearly a point deduction in the score for the mitbestellten Sennheiser headset holder. Plastic for more than 20 cents worth, cost about 5 extra, and it is simply outrageous, something Not included in with the price and the quality. Ouch.
Also disruptive: the USB unit somewhere in the middle of the cable. As it moves inevitably in a larger radius of action, the headphone cable should have been much longer. Another trigger, especially because there again 20 cents should be saved. Too bad.
