 note..... this plantronics 26716-01 coiled cord has been included with plantronics m series amplifiers for many years and works perfectly with the m series amplifiers. the off label use with cisco phones, absent an amplifier, will often yield substandard results (low volume or lack or transmission gain). i always recommend using your plantronics headset with a plantronics m series amplfier, allowing for volume control and microphone gain control. this allows you to attenuate volume to your ear AND volume out, using the microphone gain control.....
