+ Audio output is very good, because you can not complain against. Not for audiophile, perhaps, but for Electro, Pop, and other bass-heavy things perfect. o Short microphone, thus the input level is very low. o Due to the own integrated device can be activated no microphone gain in the operating system, so you have to constantly "a little louder" talk. If then the Internet line or the audio codec used are not 100% good, it slips quickly into unintelligibility. o Occasional disconnections, even if you're sitting just two feet in front of the station. For a period of 5 ~ 7 seconds you can hear nothing and is not heard until the headset has the connection restored to its sender. This happens roughly three times in eight hours, independent of battery condition. - Housing is only moderately well finished and began to participate in at least in my case, after about 6 months with every smallest movement unbearable to creak. Even on the left side, so that the sound from the microphone to the receiver of the conversation went.
The latter finally was also the reason to give away the headset again. The other shortcomings are ways royal of the purchase price bearable; but a headset, with each conversation for the opposite to torment, is missing its benefits.
