Pros: Tiny, practically weightless, and sleek-looking .. can plug into multiple computers AND the 2.5mm jack on my VOIP phones. Sound quality is first rate, others say I sound great on same system I used other headsets with negative comments. Once in position you forget the headset is there and it works well. Price is great for quality. The newegg shipping was insanely fast. Try this for Skype and Google Voice connections, it amazed me.
Cons: I have small ear canal so earbud does not sit inside my ear, a bit uncomfortable to put on and get into position. The ear clip goes above the ear, which hits my glasses.. the earclip on my other Plantronics phones fit under the ear (great great design) but they sound so bad I just don't use them any more and paid the same price. I don't like the control module on the main (3.5mm) cable, it's a bit clunky, in comparison to the sleek design of the headset itself, and it...
Pros: It's neat. I like it, and regardless of what others have said about the hard rubber that irritates their ears, they must have some sort of dumbo ears or something. The rubber piece is almost too big for me, yet is quite comfortable. Very clear sound, and good mic.
Pros: Long cable, Very clear headphone and mic, the cable can be shortened by pulling the plug above teh volume button which I think will be handy if you just need to use the headset as a speaker with laptops(The cable length shortens to about 2-3 feet). Fits comfortably on my ear, easy to adjust to fit both ears. I bought it to chat online and it works well with yahoo, skype and google talk.
Cons: no way to adjust, it fits or it doesn't. For me, it doesn't. Terrible raspy audio, bulky design so it's not portable, and I could have bought a cheapo for better. In fact, I got a free one with a digital camera I just bought, love it a lot more.
Summary: The microphone is not very sensitive, so you will have to crank everything up to max settings in windows, and in the software you are using, and also talk very loud.
Pros: It's cheap, long cord, and it looks decent.
Cons: The earpiece can be very painful. It uses a very thick, hard rubber that is not very flexible. It is not a minor irritation like some other headsets have from hours of use, these hurt right from the beginning.
