If your Poly Voyager Focus 2 mutes itself when you tilt your head, lean back, or shift in your chair, the headset isn't faulty. It's the wearing sensors misreading your movement as taking the headset off. Here's why it happens and two ways to stop it.
Quick answer
Last updated July 2026
Why the headset mutes on its own
The Voyager Focus 2 has wearing sensors in the bottom of each earcup. They're what let the headset answer a call when you put it on, mute when you take it off, and pause media when it leaves your head. Useful when they work — and the source of this exact problem when calibration drifts.
If the calibration is slightly out, tilting your head, leaning back, or adjusting the headset can read as removal. The headset does what it's designed to do and mutes. From your side, the microphone cuts out mid-sentence for no visible reason.
Myth
My Focus 2 mutes randomly during calls, so the headset must be defective.Reality
Almost certainly not. Random muting during head movement is a wearing sensor calibration behavior, not a hardware fault — the headset is correctly executing an instruction based on an incorrect reading. It's fixable in software, and if a firmware update doesn't resolve it, disabling the sensors will. Neither requires a replacement headset.Step one: update the firmware
Before disabling anything, update your headset firmware. Sensor calibration is exactly the kind of thing firmware updates address, and if an update resolves it you keep the auto-answer and auto-mute features working as intended.
Firmware updates are handled through the HP Poly Studio App — the current name for the software formerly called Poly Lens, and before that Plantronics Hub. Connect the headset, open the app, and apply any available update.
Step two: disable the wearing sensors
If the muting continues after updating, turning off the wearing sensors stops it completely. Two ways to do it.
Through the HP Poly Studio App
- Open the HP Poly Studio App with your headset connected.
- Go to Settings.
- Select Sensors & Presence.
- Turn off Wearing Sensor.
Directly on the headset
If you can't install software on your computer — common on locked-down corporate machines — you can toggle the sensors from the headset itself:
- Hold the Mute and Call buttons together for more than 4 seconds.
- The LED flashes purple, then red. Sensors are now off.
- To turn them back on, repeat the same hold. The LED flashes purple, then blue.
Worth memorising if you manage headsets for a team — it works on any Focus 2 without touching a computer.
What you lose with sensors off
Disabling the wearing sensors removes the automatic behaviors, not the functions themselves:
- You lose: auto-answer when putting the headset on, auto-mute when taking it off, and automatic media pause/resume.
- You keep: manual mute via the mute button, mute by swinging the boom arm up, and normal call answering from the call button or your softphone.
For most people that's a fair trade — a headset that mutes unpredictably mid-call is worse than one that needs a button press.
Why does my Poly Voyager Focus 2 mute by itself?
The wearing sensors in the earcups are reading your head movement as removing the headset, which triggers auto-mute. It's a calibration behavior rather than a hardware fault, and it's fixable through a firmware update or by disabling the sensors.
How do I turn off the wearing sensors on a Voyager Focus 2?
Either through the HP Poly Studio App under Settings → Sensors & Presence → Wearing Sensor, or directly on the headset by holding the Mute and Call buttons together for more than 4 seconds until the LED flashes purple then red. Repeat the button hold to turn them back on — the LED flashes purple then blue.
Will I lose features if I disable the wearing sensors?
You lose the automatic behaviors — auto-answer when putting the headset on, auto-mute when removing it, and automatic media pause. Manual mute, boom-arm mute, and normal call answering all continue to work.
Should I update the firmware before disabling the sensors?
Yes. Sensor calibration is the kind of issue firmware updates address, and if an update resolves it you keep the automatic features. Update through the HP Poly Studio App first, and only disable the sensors if the problem continues.
Is my headset defective if it keeps muting?
Very unlikely. The headset is following a sensor reading, not malfunctioning. If neither a firmware update nor disabling the sensors resolves it, that's the point to have the headset checked.
If this is happening to you, work through it in order: update firmware first, disable the sensors if it persists. The button combination is the fastest route if you can't install software. Call our team at 877-999-3838 if it continues after both.
