Excerpt: Very disappointed in this product. The felt ear pads are like the ones you get on airplanes. Yuck. They are very uncomfortable, especially on long phone calls. I also did not like the microphone placement. And the mute button on the headset doesn't operate efficiently. After three days of use I've returned this set. Logitech used to have leather ear pads on wireless sets. Now it seems like their leather ear pads are only on their non-wireless headsets.
Summary: I received the wireless headset a few weeks ago. Had no problems getting it setup and drivers downloaded, but problems came when I started using it. When you are very close to the dongle and there is not a variety of sound coming out of the system. When there is a variety of noise, such as action scenes in movies or cut-scenes in videogames, there is distortion.
