Plantronics C052A CS520 Wireless Headset + Base | 3mth Wty

The latest CS520 is for use with an office phone only and comes as a binaural wireless headset (the headset has two ear cups) and that puts it in a very unique class – there are very few binaural wireless headsets available. Manufacturers’ actually suggest that if you spend more than 4 hours a day on the phone, you should use a binaural model. The reason is twin ear cups offer a less fatiguing listener experience, since the sound is distributed equally between the ears so the volume doesn’t need to be as loud.
