Plantronics CS351 is built on digitally-encrypted DECT 6.0 technology, the Plantronics CS351 SupraPlus Wireless Professional Headset System lets contact center supervisors who desire mobility answer or end calls while away from the workstation—in unmatched comfort and with best-in-class audio quality. Combining the clarity of traditional corded technology with the mobility of wireless, the SupraPlus Wireless encourages hands-free productivity for employees and lets contact center supervisors monitor agents and handle escalation cases up to 300 feet from their desk phone. Designed for over-the-head comfort, the SupraPlus CS351 Wireless lets wearers converse easily with coworkers without removing the headset (Monaural design) or experience total-focus sound reduction (Binaural design). Both the Voice Tube and Noise-Canceling microphone filter out excessive background sound.
