I purchased the Logitech Clear Chat Stereo PC Headset in order to make calls online through Skype and also to listen to a variety of things on my computer. It works very well. I was impressed at how clear voices sound and through several test calls, I found out that my voice is clear too. The headset is very comfortable. There is padding on the ears and overall it fits my head great. It is adjustable so I'm sure it fits most head sizes. There is a built in microphone which swings down in front of your mouth when in use or can be moved away if you are just listening. I can talk with a normal voice and can be heard clearly. I like the volume control located conveniently halfway down the wire. This is nice because you don't have to fumble to find the volume control. My favorite feature is the noise-canceling microphone which minimizes the background noise of my children!
I highly recommend this product.
