Plantronics Marque M155 bluetooth earpiece

Hello,

I checked up on that headset, and according to my research there is no driver for that headset for Windows 7.

It lists it as only compatible with bluetooth phones:

M155 doesn't show up for windows 7 compatibility:

I'm sure your out of luck - maybe check the windows 7 compatibilty guide for purchasing a different bluetooth headset that is compatible with Windows 7.
