Review on 🔌 Plantronics Spare Cable Assembly: Enhanced Connectivity - 2.5mm to Quick Disconnect (Q.D) by Martha Fernandez

A good short cable connects the Plantronics QD to the 2.5mm jack on most desk and cordless phones. This adapter may not work depending on the headset and phone used. With. When I connected my 15 year old Plantronics headset to my new Panasonic cordless phone, the microphone was too quiet to be useful. When I connected it to the base unit, there was a loud background hum. However, when I used this adapter to connect my new Discover D712 headset (Plantronics QD compatible) to the same two phones, it worked perfectly. The short length of this cable is very useful when connecting to cordless phones. For a desk phone, you will likely need a longer cord.
