Customer Reviews of Plantronics Discovery 975 Replacement Headset - Bluetooth - Graphite
The only problem with these headsets is my ability to loose them. I am now hooking them to a lanyard; I cannot keep it in my ear all day long. If someone would invent a way to keep these from breaking loose it would be great. I have used the Plantronics lanyard, it hooks to the USB port, but lost 2 on that thing. I just don't think it's cool to keep it in my ear all the time. Otherwise best bluetooth I have ever had; too bad I have had 4 of them.
