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.

The slightest doubt about a specification? Contact us before ordering and we will check for you.

Frequently asked questions about this product

What battery life does this Voyager 4320 UC offer?
24 hours of talk time and 47 hours of music listening: two separate figures, the first being the one that matters for a calling workstation. A full charge takes 1 h 36 min.
Is the charging stand part of the kit?
Yes, together with a carrying case and the BT700 USB-A adapter, already paired: the workstation is fully equipped with nothing else to buy, and the headset charges when you set it down.
Do the ear cushions rest on the ear or go around it?
They rest on the ear: the design is on-ear, in stereo to shut out noise and help you concentrate. The headset weighs 162 g.
How far can you move away from your desk?
Up to 50 m, over Bluetooth 5.1: the BT700 adapter goes into the computer, and your smartphone connects directly. You can move between work areas without leaving the call.
What does Acoustic Fence technology do on this headset?
It filters out unwanted noise around the microphone, on an adjustable boom: sound pick-up focuses on your voice, for clear, well-controlled calls.
Is this Voyager 4320 UC new and under warranty?
Yes, new in its original Poly packaging, with the BT700 adapter, charging stand and case included. Your invoice serves as the warranty document and covers 1 year on this reference, the 77Y99AA.
