Poly Voyager 4320 Wireless Bluetooth Headset - Stereo, 164 ft Range

A call center floor doesn't quiet down for your shift, and staying immersed in a conversation gets harder every time you catch the person three desks over. The Poly Voyager 4320 wireless headset covers both ears specifically for that environment — the stereo sibling to the mono Voyager 4310, built for focus over awareness.

Same Class 1 Bluetooth range as the 4310, same 24-hour battery, same Acoustic Fence microphone technology — the difference is entirely in how much of the room you want blocked out. If your day is back-to-back calls in a busy space, that's the headset this page is for.

Build the exact Voyager 4320 you need

Three choices, each independent of the others.

Connector:

• USB-A. The BT700 adapter plugs into a standard USB-A port.
• USB-C. Same adapter, USB-C connector for modern laptops.

Certification:

• UC Certified. Compatible with Avaya, Cisco, Skype, 8x8, and other major UC platforms.
• Microsoft Certified. Formal Microsoft Teams and Zoom certification, with a dedicated Teams button on the BT700-M adapter.

Accessory:

• Headset Only. Headset, BT700 adapter, and charging cable.
• With Charging Stand. Adds a desktop stand — a dedicated spot to rest and charge the headset.

Mono or stereo — the real choice in the Voyager 4300 series

The Poly Voyager 4320 wireless headset covers both ears at 162g, versus the mono Voyager 4310's single-ear design at 122g. That's not just a comfort tradeoff. The 4310 is built for office managers, dispatch roles, and anyone multitasking who needs to stay aware of the room. The 4320 is built for call centers, remote workers, and anyone whose job is genuinely better done with the outside world dialed down — both ears covered, full focus on the call.

Why 164 ft only works with the included adapter

The Poly Voyager 4320 wireless headset reaches its full 164 ft (50m) range specifically through the included BT700 USB adapter, a Class 1 Bluetooth device. Pair it directly to a laptop's built-in Bluetooth instead, and range drops to roughly 30 ft — the standard Class 2 ceiling. The adapter isn't optional if the range claim matters to your setup.

A microphone certified beyond Poly's own marketing

The dual-microphone Acoustic Fence technology on the Poly Voyager 4320 wireless headset meets Microsoft's own Teams Open Office premium microphone specification — a real, named certification bar for background-noise rejection, not just a Poly-branded claim. It's not active noise cancellation for what you hear, though; Poly is direct about that and points to the Voyager Focus 2 for ANC. What this headset does is make sure your voice reaches your caller clean, even from a loud floor.

Battery life and fast charging

The Poly Voyager 4320 wireless headset runs up to 24 hours of talk time or up to 47 hours of listening time per charge, with standby stretching up to 50 days. A full charge from empty takes about 1.6 hours, and a 15-minute quick charge is good for roughly 10 hours of listening.

It's not Bluetooth-only

Plug in the included USB cable and the Poly Voyager 4320 wireless headset runs in Audio-over-USB mode — Bluetooth off entirely, every function still working. Useful on a dense call center floor where too many Bluetooth signals compete, or as a no-battery-required backup when the charge runs out mid-shift. It also charges while operating in this mode, so a dead battery doesn't mean stepping away from the desk.

Multipoint pairing and desk phone connectivity

The headset stays connected to two devices simultaneously and remembers up to eight, so switching between a work laptop and a personal phone doesn't require re-pairing. Dynamic EQ adjusts sound automatically depending on whether you're on a call or listening to media. For desk phone connectivity, Poly sells an optional Voyager Office Base separately — confirm current availability with us before ordering if that's a requirement.

This is the headset for someone whose day is genuinely better with the room shut out — a call center agent, a remote worker in a noisy house, anyone whose focus depends on not hearing what's happening three feet away. The range and battery numbers match its mono sibling exactly; the only real tradeoff is 40 extra grams for both ears covered.
