This is the second headset I have purchased from Plantronics, the first one lasted 9 years. As an Information Technology Executive Recruiter, I live on the phone, so clarity, battery charge, and mobility are very important for me and the CS500 has been great!

Headset was comfortable, sound quality was good, but unfortunately the microphone volume was not functioning normal. Sounded like I was a million miles away, regardless of settings. Troubleshot with Plantronics support, but they weren't successful either.

The headpphones were too small for it to be on both ears and I could not make it work with my panasonic phone system. Too bad. I would like to have a quality headset that functioned with the phone to avoid feedback on video conferences.
