Works, but flimsy
We use these and the newer, solid-boom models at work for taking calls and these Encore ones are total trash. The mic booms easily contort and bend, becoming permanently crimped and making it impossible to pick up your voice. The swivel for the boom loosens with use and eventually will no longer stay where you put it. In addition, the head band is not very strong so during the day your headset slowly slides off your ear due to it's own weight.I suppose if you got one new, were the only user, and babied it when you used it that it would do a good job. I mean, when I am forced to use one at work (because the new ones are all being used) I still get my job done, but it isn't comfortable or convenient. At all.
