Excerpt: I ordered this headset to use for several web seminars and meetings to be able to participate in the training without having to dial in to a separate number and deal with all the background noises and such. this headset was very easy to install, audio was very clear, and the microphone worked well for the times it was needed for questions or comments. Great value!
Summary: I downgraded to four stars, because I specifically searched for a headset with a USB port and this showed up in the search. Dual 3.5 mm are a pain in the neck, literally, as connection is limited to the back of the computer, rather than a USB hub. I also had to use my Windows 7 Control panel to make them operate with Windows Movie Maker and Skype. Otherwise they are excellent, particularly with canceling outside noise.
