I bought a Logitech Clearchat Pro USB Head Set with built in mic a while ago - for the most part they were fantastic. I took them with me when we went to Europe recently as i had to make some voip calls back in Australia that were work related.
Brother in-law loved them that much, that i left them with him.
So when i got back home, i had a look at the Logitech products again as i was happy with the old USB headset VOIP ( mic and audio ) quality an such, and decided to get the Logitech Clear Chat Wireless Head Set this time round.
For the most part i am very satisfied with the quality - i predominantly use it with X-Lite on my main PC. It passes the test with gaming, music, movies, and VOIP quality is pretty great for a wireless device. All in all, it gets 9/10 from me.
