Poly Voyager 4220 Office Stereo Bluetooth Headset with 1-Way Base (212721-01)

The Plantronics Voyager 4220 Office is a two ear Bluetooth over-the-head style headset that connects to a computer or desk phone through a USB-connected wireless/charging base, or a mobile device via Bluetooth. It features a larger wireless range than the 4220 UC, a noise-canceling microphone, and earpiece-integrated call controls. The wireless/charging base comes with a USB-A cable, and it can connect to non-USB desk phones via EHS cable (sold separately). It also has a one ear model (4210 Office), a UC model for use with a USB wireless adapter, and two-way-base models for simultaneous desk phone/computer connections.
