I use headsets with my cordless phones, because I have friends I talk to for hours at a time. Holding the phone to my ear, I find my arms and shoulders get tired.So I bought a headset years ago. I loved it, but it finally died. I've been looking for one just like it, and this one fit the bill. It has the same longer than average, flexible boom microphone (with the foam anti-wind cover) and a headset that doesn't try to crush my skull. I have tried so many, and I very highly recommend this one. It has a "mute" button, so I can press it, answer a question from my husband, or shoo a cat off the couch, then press it again, and there's no interruption of the conversation with my friend.This isn't a necessity, by any means, but if you're a talker, you should have this. You can talk longer, more comfortably! It uses the standard 2.5 jack most cordless phones have. I really do love this thing. (And my husband finally got a headset, too - he talks as long as I do!!)
