Frequently Asked Questions

HP Poly Voyager 4320 UC Stereo USB-A Headset (77Y99AA, 218476-01)
Frequently Asked Questions (FAQ's)



What devices can the Voyager 4320 UC connect to out of the box?
  • It pairs to a PC or Mac through the pre-paired BT700 USB-A Bluetooth adapter (or by plugging in the supplied USB-A cable) and to a smartphone over Bluetooth 5.2; an optional Voyager Office Base lets you add a desk phone later.
    • Is it certified for Microsoft Teams and other meeting apps?
  • Yes. The stereo 4320 is officially certified for Microsoft Teams, Zoom and Google Meet, so the call-control buttons and the Teams-purple LED work natively with those platforms.
    • How far can I roam before the audio cuts out?
  • You can walk up to 50 m / 164 ft from the computer when you’re using the BT700 adapter, giving you freedom to grab coffee or pace while talking.
    • How much talk and listen time do I get on a full charge?
  • Expect up to 24 hours of talk time or 47 hours of music/listening on one charge—among the longest runtimes in its price class.
    • Does it support quick-charge for emergencies?
  • A 15-minute top-up delivers roughly 10 hours of listening, and a full recharge takes under two hours, so you’re rarely tethered to a cable.
    • How well does the microphone handle background noise?
  • The boom houses a dual-microphone Acoustic Fence array that digitally blocks office clatter so callers hear only you—even next to a clacking keyboard or barking dog.
    • Can I mute quickly and know I’m muted?
  • Pinch the boom or press the dedicated mute button; the headset gives a spoken “mute on” prompt and a dynamic mute alert warns you if you start talking while muted.
    • Does it remember multiple devices?
  • Yes. It keeps eight devices in memory and can stay connected to any two simultaneously—ideal for toggling between laptop and phone without re-pairing.
    • Can I use it as a wired USB headset?
  • Absolutely. Plug the included USB-A cable into your computer and the headset switches to audio-over-USB mode while charging at the same time.
    • Is there an on-headset busy light?
  • A red online indicator on the earcup can be turned on via Poly Lens so colleagues know you’re on a call (or off when you prefer).
    • How heavy is the stereo model during all-day wear?
  • The Voyager 4320 weighs about 162 g (0.35 lb), light enough for day-long calls without head-pinch.
    • What’s included in the retail box?
  • You get the headset, BT700 USB-A adapter, soft carry pouch, USB-A charge/audio cable and a quick-start guide; the 77Y99AA bundle also adds a desk-charging stand.
    • Are the ear cushions comfortable and replaceable?
  • Cushions use plush memory foam and simply twist off for replacements, so comfort stays high even after heavy use.
    • Does the headset protect my hearing?
  • Poly SoundGuard DIGITAL limits sudden spikes to 118 dB and keeps daily exposure below 85 dBA to meet global safety guidelines.
    • What Bluetooth profiles and codecs are supported?
  • The Class-1 radio supports HFP, HSP, A2DP and AVRCP profiles over Bluetooth 5.2, so you get wide-band speech plus stereo music on any modern device.
    • How do I update firmware or tweak settings?
  • Download the free Poly Lens desktop or mobile app to push firmware, adjust sidetone, remap buttons or turn the busy light on/off in a few clicks.
    • What’s the difference between Voyager 4320 and 4310?
  • The 4320 is a two-ear (stereo) model weighing 162 g for immersive sound, while the 4310 is a single-ear (mono) version at 122 g; all other specs are the same.
    • Can I switch seamlessly between music and calls?
  • Yes. Smart sensors auto-pause music when a call comes in and resume playback afterward, so you don’t miss a beat (feature enabled via Poly Lens).
    • How does it sound for music, not just voice?
  • Reviews note surprisingly full bass and rich stereo detail, making the 4320 enjoyable for playlists when you’re off the clock.
    • Is there a carrying solution for travel?
  • A slim fabric pouch is supplied to protect the headset, dongle and cable in your backpack or carry-on, keeping hybrid workers mobile and organized.
