Plantronics CS540 Wireless Headset

This phone works well and is easy to hear on. There are dials on the bottom that give you more control over volume. There is a slight delay for the pick up of the receiver. We don't travel far from the base so I cannot speak to the range of the...

I was looking around for a "good" reliable wireless headset. I had reviewed several at local retailers. When I settled on this one, I then looked on line and there it was on Amazon. bought it, and just love it. I use it daily, and am able to walk...
