Now, as I already exchanged the headset and wanted to push the scratching sound in the ear almost to the keyboard I looked but then again here in the reviews and also had to realize to myself that just the adapter is broken. Turning him long enough and pulls something about him, there is exactly a small position in which the sound in both ears is acceptable. However, the adapter is leaving this position as soon as the slightest movement takes on the cable. Too bad!
