I have been using one of these headsets to handle calls on my business (land-line) phone for several years. I have gotten HOURS of use out of this headset. It is comfortable (both over the ear and in the ear canal) and durable, as well as easy to flip to be used on either ear. I came by this one so easily (it was the first one I bought), I thought all headsets were created equal (and equally utilitarian). Now I know differently. I started looking for an additional headset to keep in my car for using my cell phone. Unfortunately, there is no other headset that I have tried that has the same comfort level! I have returned 2 now (ATT - earpiece won't stay on/doesn't fit; Wireless brand (broke when I tried to remove it from the package). I'm going to stick with this, the tried & true! In fact, I think I'll get two of them (one spare or for one of my kids)! The one drawback is that the microphone picking up my voice is not that sensitive. However, I use the clip on the wire to attach it to my earring. This makes the microphone fall right below my mouth, and others can hear me perfectly. For those who do not wear earrings, clipping to a collar will work, but I would say that the mic must be within one inch of your mouth to provide the right volume for your listeners. This is why I gave it 4 stars instead of five. Also note: this is a bare-bones set - no volume control or mute. However, it is the perfect headset for me.
