I have two bluetooth headsets that I use for work, one primary, and one backup. My primary went out and I needed a new secondary so I found this Motorola H500. It works great as if it was brand new even though it was refurbished. The sound and microphone is great.The only thing was that it had a few nics and abrasions on the outer portion of the unit but this is to be expected because it is refurbished.
