I bought this headset (as well as the binaural version) for a Meridian phone and I'm very happy with it.
Before that I tried Ovislink models, cheaper, but which broke after only a couple of weeks (very poor plastic quality).
This Jabra one is sturdy, light and has a good sound quality. The microphone comes with a foam cover to cancel noise. The soft ear cushions are very comfortable.
I recommend it.
