Summary: Great range & sound quality however it has two failings 1. The handset lifter is quick to pickup, but slow to switch the audio. I've tested this on 3 models of Polycom IP phones and it's worse on all this unit that my previous Plantronics one. 2. If you use the earhook, they don't last more than a year due to a design fault where there plastic/rubber meets the metal inside. The earhook splits at this point. Don't believe me?
Summary: The quality of this headset is excellent - we were guided to it by our online consultant and her advice was spot on. At the moment we are using this on our older Commander system but soon we shall be upgrading to a computer based telephone exchange system and this headset ticks all the boxes with this set up too.
