Summary: I bought this after experiencing compatibility problems between a MacBook Pro and two different USB headsets. This plugs into the computer's headphone port, and it just works. Sound automatically switches from the built-in speakers to this headset when you plug in.
Excerpt: When I searched for phone headsets, this popped up. It looked like what I needed until I got it. It didn't work with my office phone. Wish it would be put into a different search engine if it doesn't work with regular telephones.
Excerpt: I searched for Telephone headsets and this came up. It looked great so I ordered it, but it CANNOT be used with a standard phone. I think the product would probably be great but couldn't use it for what I bought it for. Returning it.
