Summary: I borrowed these from my roommate when my other headset broke, so these are my impressions from 1 day of use. Used during a raid. Also, as I've said these were borrowed so I'm not sure how they are new but, the mic was a little wobbly/loose and the headband kept sliding. Something to watch for.
Pros: Sound quality - 9/10 Music sounded ok, Mic quality - 10/10 People said they could hear be better than my other headset (3.5mm connector). Connecting and Setup - 10/10 Windows 7 quickly found and configured the headset with no help from me. Raidcall was a bit trickier but that's not the headset's ...
Cons: Comfort - 0-10 The ear pads are so hard.. it felt like 2 rocks crushing my ears immediately after putting them on. Ears numbed after a few hours but couldn't wait to get them off. These are the only real issue I have with these, but its painful from start to finish.
Excerpt: I use these for online conferencing every day and want to use them for some podcasts, but haven't gotten to that yet.
Sound quality is good, people on the other end say it's good too.
The inline volume control and mute are nice and work great with Windows 7.
They just aren't very comfortable.
Summary: Great mic and speakers for the price, but minus 2 eggs for ear pain.
Pros: The built in mic picks everything up great and the sound is pretty good to my non-audiophile ears as well. USB connectivity is very fast, no drivers needed, and the cord can be run over repeatedly and still be fine.
Cons: Unfortunately this headset does get uncomfortable, even painful, after about 3 hours, generally around the tips and sides of the ears. I think it's because the headband pulls the speakers towards each other so hard.
Summary: My second pair just died out on me and I think you should know that if you are going to buy this for a tabletop computer, you may want to wrap up the wires to allow you maximum movment without accidentally snagging it. Once you snag it, the sound will most likely go out in one ear.
Pros: Very crisp sound and a high quality microphone for $30-40. Very easy to use. (Just plug it in and give it a second.)
Summary: I ended up wearing the headset around my neck and routing the incoming sound to my external speakers, just using the headset as a mic. It just hurt too much after a half hour of wearing the headset to keep going.
Pros: Good sound, good mic pickup, very easy to use.
Cons: If you're an avid gamer or need to wear the headset for extended periods of time it will start hurting.
