I had the opportunity to test the AKG headset in Saturn yesterday. The headset makes a stable, good quality impression. Just as it was stretched in the shop, it would long ago have to be broken, if it were not well made. The sound without NC could unfortunately I could not test, because it was too loud in the shop. With only the NC, it was noticeably quieter. Except for a few voices in the background very pleasant. Sonically the AKG with NC is really great. His sound has pleased me very well. Bass, middle and treble ware where I expect. I also had the impression that the AKG good spatial and detailed representation offered. The headset is tight, but pleasantly. I would imagine that it is sitting still enjoyable even after a long time. What really annoyed me was the bezel to turn on the NC. Super design, totally impractical to use. That would be for me already a reason not to buy it.
