Non-contractual photos

The visuals on this page are supplied by the manufacturer. They are frequently produced for a whole range — not for the exact model you are viewing: what you see in the photo is never a promise of what is included.

No exchange, return or cancellation will be accepted on the grounds that something seen in a photo (accessory, port, colour, keyboard layout, packaging…) is not found on the delivered product. Only the specifications written on the page are binding for the order.

What the image does not guarantee:

  • Staging : microphone stand, boom arm, pop filter, mounts and ambient speakers photographed are not included unless stated.
  • Quantity : the number of speakers or channels visible in the image does not necessarily match the set sold.
  • Cables and tips : the cables, adapters, ear tips and cases supplied are those listed in the specifications.
  • Specifications : Bluetooth, jack socket, USB, noise cancellation and battery life cannot be read from a photo.
  • Colour : one image often serves several colours, and the shade you see depends on studio lighting as much as on your screen settings; the colour sold is the one in the title and the specifications.
  • Props and accessories : the items shown around the product (cables, stands, decorative objects, content displayed on screen) are not included unless explicitly stated.
  • Packaging : boxes, labels and bundles change with the manufacturer's revisions: the packaging delivered may differ from the one in the photo.

What is binding: the product title, this page's technical specifications, the description and, when provided, the manufacturer's PDF datasheet available in the downloads.

Frequently asked questions about this product

Does the charging stand come with this Teams certified version?
Yes, this reference is supplied with its charging stand: you set the headset on it between calls, with no cable to plug in. A carrying case comes with the set.
How much freedom of movement does this headset give you?
Up to 50 m of wireless range: you stay on the call while fetching a file or joining a colleague at the other end of the floor. That is the main practical difference from a wired headset.
Does it need charging every evening?
24 hours of talk time and 47 hours of music: two separate figures, the first being the one that matters for a workstation. A full charge takes 1 h 36 min.
Can you keep making calls with a flat battery?
The headset switches to USB wired mode: the conversation continues over the USB connection instead of the wireless link. Poly presents this mode, together with the charging stand, as the way to extend talk time.
What is Acoustic Fence on the mic boom for?
It is the processing that reduces unwanted noise around the microphone: built into the boom, it focuses sound pick-up on your voice and leaves out the bustle of the floor. The person you are talking to hears a conversation, not an open-plan office.
Why a stereo version rather than mono?
Two ear cups shut out noise and help you concentrate on calls as well as music. The trade-off is that you hear your team less well: the mono version exists for reception and the switchboard.
Does the headset also connect to a mobile phone?
Yes, the headset connects directly via Bluetooth to the phone, in addition to the dongle plugged into the computer. It supports the hands-free and A2DP profiles, so calls and music alike.
At 162 g, is it comfortable through a day of meetings?
162 g, in an on-ear design — the cushions rest on the ear rather than around it. A carrying case is supplied for travel.
Is this POLY Voyager 4320-M Teams new and under warranty?
Yes, new in its original Poly packaging, stand included. Your invoice serves as the warranty document and covers 1 year on this reference. This is the Microsoft Teams certified version.
