This item is a Poly (formerly Plantronics) Savi 8210 Office Wireless DECT Headset System. It appears to be new in open box. I got this from a business that closed.

The Savi 8210 Office Wireless DECT Headset System from Plantronics features an over-the-head headset design that offers a wireless range of up to 580'. The headset is designed to deliver enterprise-grade DECT audio for a premium listening experience with noise-canceling, hi-fi stereo sound support. It also features an all-in-one charging base with 3-way connection to a PC, mobile phone, and desk phone. It lets you transfer audio between the headset and a smartphone with the press of a button, and the entire system supports both DECT 6.0 and Bluetooth 4.2 connectivity.

• The built-in active noise cancelling microphone blocks out background noise, so you can have your calls with minimized distraction. For sensitive environments, you can turn up noise cancellation with the system's close conversation limiting feature, which is configurable via the Plantronics Hub for privacy.
• The boom microphone is flexible, letting you adjust it to your preferred distance while speaking.
• An adaptive power system allows you to downshift to a low power mode when the headset is close to the Savi 8210 Office base to save battery life. This feature contributes up to 13 hours of talk time before needing a recharge.
• The headset's microphone boom is designed to be flexible so it can be positioned at an ideal distance from your mouth for optimized voice quality.
• The Savi 8210 Office Wireless DECT Headset System has integrated voice alerts that notify you when you've muted the headset or have stepped out of range.
• The Savi 8210 Office Wireless DECT Headset System is built for UC applications and soft phones from Avaya, Cisco, and others.
• A ringer is conveniently built-in to the base with volume controls for off, low, medium, and high.
• DECT Security certified, which utilizes the latest standards in DECT wireless security.
• Other helpful features include audio transfer capabilities, and a one-touch button to answer and end calls, manage volume settings, mute, and flash.
