I bought it to communicate via Skype at work until they give out a working headset, so I took one of the simplest ones. If they cost 250 - there would be no complaints. But for their price and from such a manufacturer, I expected at least working quality. But no. At the volume turned up to the maximum, the interlocutors can hardly hear me, sometimes I have to repeat 2 times, putting the microphone almost into my mouth. It is also difficult to sit in them for more than an hour, because they are hard and uncomfortable. Before that, there were svens a little more expensive - there were no problems at all.
