The Logitech PC 960 offers the comparatively low price, long life (my last was over 3 years) and good quality (both microphone and headphones). Via a controller, which you can also plug it on clothing ends, the volume can be set on and off the microphone by pressing a button (jargon: seem), which is indicated by a LED. Negative imputable would the headset more than that of the clip, with the one it attached to clothing, breaks off quickly in case of accidental exposure. Here, a flexible metal bracket would have been much better. Otherwise convinced the headset, however, in all categories, offering an excellent price / performance ratio.
