I love my headset. I really do. I am construction estimator, and I am running purchasing on an out-of-town project. I have many many many many lengthy conversations with subcontractors to discuss bids and scopes of work and I move around my office to look at plans. My chin had broken out from holding the phone to my face for so long! My neck ached every day. My employer had no trouble approving my request, and with Amazon Prime it arrived two days later!So for a mere $180 or so, we've avoided that workers comp claim! I am free to move about the office, even run to the copier without missing a beat.I downgraded a star for the fit and the trouble it took to change the ear-tip. It takes a while to get the hang of getting it on the ear in time to answer the phone (I don't wear it when I am not on a call.) Then with the original ear-tip, it would fall off. So I replaced it. I kept trying to remove the tip and I am certain I was following the diagram, but it wouldn't come off. You have to turn it 1/4 turn past the stop and then remove it (thanks IT guy!) I put the big sticky plastic one on there, and now it stays in my ear pretty well.It comes with a packet of ear-tips, one of each kind at least and more. So don't purchase more unless you share with people. Recommend that you check with your IT or communications folks to make sure this is compatible with your phone prior to ordering.Also, turn it off when you take it off, the battery lasts most of the day, but not if you leave it on.
