Headset Troubleshooting
The overwhelming majority of headset complaints come down to the wrong device being selected somewhere. Before suspecting hardware, check the three places an audio device can be set — the system default, the communications default, and the meeting application — because a mismatch in any one produces symptoms that look like a broken headset.
Check these three first
- System default playback and recording device
- System default communications device — separate on Windows and frequently different
- The device selected inside the meeting application itself
- Then: is the headset muted at the headset, as well as in the software?
Start here
| Symptom | Most likely cause |
|---|---|
| Nobody can hear you | Wrong recording device, or muted at the headset |
| Call audio comes from laptop speakers | Communications default device not set |
| You cannot hear the other party | Wrong playback device, or volume at the headset |
| Buttons do nothing | Not the certified variant, or companion software missing |
| Muted in software but not on the headset | Mute state out of sync — a certification issue |
| Wireless cuts out intermittently | Range, interference, or using laptop Bluetooth instead of the adapter |
| Battery lasts a fraction of what it did | Normal cell ageing after a few years |
| Robotic or distorted audio | Interference, or a USB hub issue |
| Very quiet microphone | Boom position, or input level set low |
| Echo heard by the far end | Speakers active alongside the headset |
| Headset not detected at all | USB hub, cable, or port |
| Works in one app, not another | That application has its own device setting |
Nobody can hear you
- Check the mute button on the headset itself Obvious, and genuinely the answer a large share of the time — particularly when the software shows unmuted, because the two can be out of sync.
- Check the recording device in the meeting application Applications keep their own setting and do not always follow the system default.
- Check the system recording device and its level Confirm the headset microphone is selected and the input level is not near zero.
- Check the boom position Pointing away from the mouth or rotated up produces a very quiet, distant sound. Boom toward the corner of the mouth.
- Test in a different application A voice recorder confirms whether the microphone works at all, which splits hardware from application configuration in seconds.
- Try a different USB port, avoiding hubs Unpowered hubs cause intermittent audio device problems that are easy to misread as headset faults.
If muting on the headset does not mute in the application, the two are tracking mute independently — and someone will eventually speak for a minute believing they are unmuted, or worse, believing they are muted. This usually means the headset is not the certified variant for that platform, or the companion software is not installed. Fix it properly rather than telling people to only use one mute button.
Audio coming from the wrong device
This is the Windows default-device split, and it accounts for a large share of headset support calls.
- Set the headset as the default device in sound settings.
- Set it as the default communications device as well. This separate setting is what applications use for calls, and it is why music plays through the headset while calls do not.
- Set it inside each meeting application, since these keep independent settings.
- Check for application exclusive mode, which can let one application seize the device.
- Re-check after Windows updates, which occasionally reset audio device preferences.
- Watch for the adapter and headset appearing as separate devices — select the correct one, which is usually named after the adapter for wireless models.
Wireless dropouts
| Cause | What to do |
|---|---|
| Using laptop Bluetooth instead of the adapter | Use the supplied USB adapter. It gives better range and more reliable behaviour than built-in Bluetooth. |
| Adapter in a rear or obstructed port | Move it to a front port, or use a short extension so it is not behind a metal chassis or under a desk. |
| 2.4 GHz congestion | Bluetooth shares spectrum with Wi-Fi. In dense offices this causes intermittent breakup — one reason DECT suits high-density headset environments better. |
| Genuinely out of range | Bluetooth range is around a desk. If someone walks the floor while talking, they need DECT. |
| Firmware | Connection stability fixes are common in headset firmware updates. |
| Docking station USB issues | Try the adapter directly in the laptop. Dock USB ports sometimes handle audio devices poorly — see docking station troubleshooting. |
Battery life
- Gradual decline over years is normal. Lithium-ion cells lose capacity with charge cycles, exactly as in any device.
- Dock between calls rather than running flat. Partial top-ups are gentler than deep discharges.
- Check the charging contacts and cradle if it is not charging. Dirty contacts are a common cause misread as a dead battery.
- Keep it off hot surfaces. Heat ages cells faster than use.
- Check firmware, since power management improvements do appear in updates.
- Replace the headset when a full charge no longer covers a working day. On most business headsets the battery is not user-replaceable, so this is end of life.
A wired USB headset needs no charge, no pairing, and no configuration beyond selecting it. As a loaner it gets someone back on calls in thirty seconds while you deal with their actual problem — which matters most for exactly the people whose headsets fail, because they are on calls all day.
When it is genuinely faulty
- Microphone works in no application after checking every device setting.
- Audio in one ear only, which usually means an internal cable failure at a flex point.
- Physical damage to the boom or headband, common and generally uneconomic to repair.
- Will not hold charge for a working day after several years of service.
- Not detected on multiple computers, which rules out one machine's configuration.
- Persistent crackling on a wired unit, typically a failing cable near the connector.

Firmware tools, companion software, and platform-specific behaviour vary by model. Confirm against documentation for the exact part number.
Headset problem you cannot pin down?
Tell us the model, the platform, and whether it fails in every application or just one. That last detail usually separates a device setting from a genuine fault in under a minute.
