How To Reset Plantronics Headset

Plantronics (now Poly) headsets are built for daily calls, but they do lock up sometimes. Audio drops, Bluetooth won’t pair, or the base just sits there with a flashing light. At that point, you start looking for how to reset Plantronics headset without guessing and pushing random buttons. The right reset depends on the series you own – Voyager, BackBeat, Savi, CS, or an office base. I’ll keep each method clear, short, and safe so you can get the headset back to a clean state and reconnect it in minutes.

If you also use other brands, you can follow their reset steps in our guides for Sony, Beats, Bose, and JBL headphones.

Universal Reset Methods

Poly (Plantronics) headsets store button states, Bluetooth links, and audio routing in temporary memory. When that data corrupts, the headset stops pairing, LEDs freeze, or controls stop responding. The resets below clear those states safely across most Voyager, BackBeat, CS, and Savi models.

1. Soft Reset (Bluetooth Models)

Clears minor pairing faults and frozen buttons.

1. Turn the headset off.
2. Hold Call + Volume Down (–) for 6–8 seconds until the LED flashes.
3. Power the headset back on and re-pair.

2. Factory Reset (Supported Models Only)

For headsets that allow deep cache clearing.

1. Turn the headset off.
2. Hold Call + Mute for 8–10 seconds until the LED pulses rapidly.
3. Release the buttons and restart.

(Models without a Mute key use Call + Volume Up (+).

3. Clear Bluetooth Pairing Profile (All Bluetooth Models)

Resolves stale or duplicated entries preventing reconnection.

1. Remove the headset from your device’s Bluetooth list.
2. Put the headset into pairing mode (red/blue flash).
3. Reconnect as a new device.

4. USB Dongle Reset (BT600 / BT700 / D200)

Fixes desynchronization between the headset and its adapter.

1. Unplug the dongle.
2. Wait 5 seconds.
3. Plug it back in and allow auto-resync.
4. Re-pair if needed.

5. Base Station Reset (CS / Savi Office Models)

Restores DECT link between the headset and office base.

1. Disconnect the base’s AC power.
2. Wait 7–10 seconds.
3. Reconnect power and dock the headset.

6. Software Reset (Poly Lens / Plantronics Hub)

Used when button resets don’t clear audio or routing faults.

• Poly Lens: Settings → Device Actions → Reset Configuration
• Plantronics Hub: Settings → General → Restore Defaults
