Rated 5 out of 5

Great headset, solid product, and strong stable signal.

We up graded to this system because of radio interference in our building. It was simple to set up and flawless in function. The fit of the microphone is different that the one I had previously used, which has taken some getting used to. Having said that it stays in place better and so produces a more consistent audio level.
