Excerpt: I tried 2 different sets of Wireless Logitch USB headsets and the Mic on both failed and were returned...great support by B&H. The "Wired" USB headset by Logitech works just great.
Pros: head set is amazingly clear, the directional mic works perfectly, it almost completely eliminates all back round sound, the little red mute light in the speaker and ear piece controls are very nice
Cons: if you move around to much the headset falls off :( for but for the price its not a bad con
Pros: Comfortable fit on my head, yet still allows me to hear what's going on in the rest of the house. Worked first time on both XP and Windows 7 with no additional software, besides adjusting the control panel audio settings to send data to the headset.
Cons: The microphone does not swivel as far downward as I would like it to. The lowest angle it goes to is slightly above my upper lip, which puts it in my lower peripheral vision. Nitpicky con, but there it is.
