Motorola W755

I love the phone.I have been having problems with the voice recognition on the bluetooth not the phone.I have the Plantronics Explorer 222.The sound quality is good.I would say 50% of the time when I tell the bluetooth to call a particular name it gets it wrong.Not even close and it calls the wrong person and I can't seem to disconnect in time. This is the second one I have tried.I tried adjusting the voice recognition on the phone.It's a shame because I like the clarity.
Any suggestions?
