    FAQ

    Frequently Asked Questions

    Why does call audio quality drop when using the mic?
    Many users notice reduced audio quality during calls when the mic is active over Bluetooth. This is a limitation of Bluetooth connectivity and isn’t unique to the Voyager 4320. With the Poly Voyager 4320 you can use USB wired mode—it bypasses Bluetooth codec limitations and delivers clearer sound.
    Can I use the headset without Bluetooth active?
    Yes: plug in via USB cable and disable Bluetooth on your device. The headset will work as a wired USB device. Although the headset may light up when turned on, it will rely solely on the wired connection .
    How do I pair to mobile phones and computers simultaneously?

    • Computer pairing: Plug in the BT700 USB‑A/C adapter and turn on the headset.
    • Mobile pairing: Hold the power switch until red/blue LED flashes, then pair via phone Bluetooth settings.
    The headset can remember up to 8 devices and maintain active connections with two simultaneously
    Why is the mic not working in Microsoft Teams?
    If your mic works in other apps but not in Teams, ensure:

    The headset is the default mic in Windows Settings.

    The device driver is up to date.
    Uninstall and reinstall Bluetooth audio drivers if needed. Also, try using the BT700 adapter instead of direct Bluetooth
    What’s the wireless range in real world use?
    The headset advertises up to 164 ft (50 m). In tests, users typically get about 70–80 ft before signal drop—still about 20 ft more than many competing headsets
    How do I fix echo or sound issues?

    Common fixes include:
    • Update firmware via Poly or Plantronics Hub software.
    • Disable conflicting drivers like Intel Smart Sound Technology from Device Manager.
    • Restart the PC, unplug and replug the dongle/headset.
    These steps often resolve echo, low volume, or mic issues
