I guess I'm the first reviewer on this as I could not find anything on this myself before purchasing.  My needs are a home-based business and I'm constantly on a headset taking orders and dictation.  My wired headset got very staticky and annoying as each time I went to answer my phone and reach for the headset, the wires would pull at everything in its path!  I'd answer my phone with half my desk stuff on the floor!
