Poly Voyager 4320 UC — Stereo Bluetooth Headset with BT700 USB-A Adapter and Charging Stand
Up to 24 h talk timeCharging stand includedAcoustic Fence microphone50 m Bluetooth range
The Poly Voyager 4320 is a dual-ear Bluetooth office headset, and part number 77Y99AA is the specific bundle that includes the BT700 USB-A adapter and the desk charging stand — which is exactly what separates it from three near-identical order codes. It runs up to 24 hours of talk time, reaches 50 m from the adapter and uses Poly Acoustic Fence technology to keep the voices around you out of the call. A 32 mm driver on each ear covers 20 Hz to 20 kHz, and the online indicator lights up so colleagues can see you are busy.
Compatibility — check before buying:
This bundle uses a USB-A BT700 adapter. On a USB-C-only laptop it needs a hub or an adapter you supply, and a cheap passive hub is the usual reason a dongle drops calls; if your machines are USB-C, the equivalent bundle is 76U50AA. It is also the UC build — certified as Microsoft Teams Open Office, Zoom and Google Meet, but not the dedicated Teams variant, which is the Voyager 4320-M. Worth knowing before you enable it: switching the online indicator on costs about six hours of talk time, 18 instead of 24. And this model has no active noise cancellation; Acoustic Fence and SoundGuard work on the call and on hearing protection, not on quieting your own ears. Tell us your ports and platform and we will confirm the code.
Best For
✓ Desks that want the headset docked and charged between calls
✓ Long call days where 24 hours of talk removes the charging question
✓ Offices on Zoom, Google Meet or Teams Open Office
✓ Users who move around a floor rather than sitting still
✓ Shared desks where a stand keeps the headset in one place
✓ Staff pairing a mobile alongside the computer
Key Features
A charging stand in this bundle, not an accessory
Order code 77Y99AA is the version that ships with the desk charging stand. Near-identical codes do not: 76U49AA is the same headset and adapter with no stand. If the headset should live on a dock, this is the code that delivers it.
Up to 24 hours of talk, 50 days of standby
Poly publishes 24 hours with the online indicator off, 18 hours with it on, 47 hours of music and 50 days of standby. A full charge takes under 1.6 hours, so a lunch break covers most of a working day.
Acoustic Fence keeps the office out of your calls
Two noise-cancelling microphones covering 100 Hz to 6.8 kHz, with Poly Acoustic Fence creating a boundary around your voice. SoundGuard Digital protects your hearing from sudden bursts on the line.
Range that covers more than a desk
Bluetooth 5.1 with up to 50 m from the BT700 adapter, and up to 91 m with a Voyager Office Base — that base is a separate accessory, not part of this bundle. The headset weighs 162 g and folds flat for the supplied pouch.

Frequently Asked Questions
Singular Expert Insight
The Voyager 4320 exists in at least four order codes that look the same in a catalogue and differ in ways that matter on the desk: with or without the charging stand, USB-A or USB-C BT700, and UC or the Teams-dedicated -M build. This one is UC, USB-A, with the stand, which is the combination most offices actually want if their machines still have USB-A ports. Where it fits against the competition: it trades active noise cancellation for battery life and a charging dock, so it suits a moderately noisy office where people move around more than they need silence. If the room is genuinely loud, an ANC model such as the Jabra Evolve2 55 is the better answer. One practical note for the quote: HP does not publish EAN codes for its accessories, so match by part number rather than barcode. Compare the range in office and VoIP headsets, or look at video conferencing kit if the calls are increasingly held in rooms rather than at desks.
Buyer’s Guide
Buy it if
You want a wireless stereo headset that docks on a stand, runs 24 hours between charges and comes with its own USB-A adapter, on Zoom, Google Meet or Teams Open Office. 162 g, 50 m of range and a pouch for carrying it home.
Skip it if
You need active noise cancellation, or your laptops are USB-C only — 76U50AA is the USB-C bundle. Skip it too if your office wants the dedicated Microsoft Teams build, which is the Voyager 4320-M rather than this UC code.
Also consider
The same bundle without the stand, 76U49AA, if desks are short of space; the USB-C bundle 76U50AA for newer laptops; or the Jabra Evolve2 55 if active noise cancellation matters more than battery life.
