Poly QD-N1 Headset Adapter This Poly/Plantronics QD-N1 Headset Adapter 65287-01 features a special 2.5mm plug prong adapter with 3 black bands (rather than the normal 2 black bands found on cell phone headsets). The other end of the cord has Quick Disconnect to snap together with Cisco 7920 Wireless IP Phone and assembly with Resistor Kit for use with any Plantronics H-series headsets such as H91-CIS or H101-CIS which are specially engineered with increased RF shielding to mitigate any buzzing sounds due to the strong signal of the cordless phone.
