I have had it with Bluetooth! I spend more time fiddling with the Bluetooth headsets (any manufacturers) than is reasonable, plus when they are signalling in and out it is very distracting and othen the calls are not clear. I am in outside sales so I rely on my cell phone. I searched high and low for a decent wired headset and this one fits the bill. I purchased it originally from a local office supply store, but it dod not have the call answer/end button and was $39.99. I did however like the fit and fucntion. I returned that one and purchased 2 of these from Amazon for basically the price of one at the store and it has the call answer/end button I want. Great design - I wear glasses so the under the ear is great. I also wear earrings that often dangle and they don't get in the way of this design. Best I have ever seen and I know Plantronics makes good products. Volume control also a plus!So if you are like me and have had enough of Bluetooth and are looking to "regress" to a wired headset give this one a look-see, I think you'll agree with me!
