The Plantronics CS520-XD Wireless Binaural Headset features 900MHz technology and allows you to multi-task from up to 350' away. The headset features fingertip audio controls and allows you to conference in up to three additional CS500 XD Series headsets (sold separately).
The headset's 900MHz wireless technology allows for a high number of available channels and clear conversations. You can select either narrowband mode to preserve talk time or wideband mode for clearer conversations. The noise-cancelling microphone reduces background noise interruptions. Additionally, Enhanced Digital Signal Processing (DSP) offers for more natural sounding voices. The CS520 allows for up to 8.5 hours of talk time.
