Codec latency
Bluetooth buffering and codec choice add delay that a browser cannot remove completely.
Bluetooth Audio Delay or Poor Quality
Wireless audio is late, unstable or switches to low-quality sound.
- 01
Move closer and remove radio obstructions.
- 02
Close apps using the Bluetooth microphone.
- 03
Forget and re-pair the device, then compare with a wired output.
Most useful causes to check
Hands-free profile
Using the headset microphone may switch the connection to a lower-bandwidth voice profile.
Interference
Distance, crowded 2.4 GHz radio traffic and low battery can cause retries and dropouts.
Repair steps by system
Interfaces change between system versions. Use the setting names as landmarks, then return to the same test.
Windows
- Open Settings → System → Sound and verify input and output devices.
- Open Volume mixer and confirm the browser is not muted or routed elsewhere.
- Disable enhancements temporarily and retest.
macOS
- Open System Settings → Sound and verify the selected output.
- Check output volume and the left/right balance control.
- Reconnect the device, then quit and reopen the browser if routing is stale.
iPhone and iPad
- Open Control Center and check the current AirPlay output.
- Open Settings → Accessibility → Audio & Visual and review mono audio and balance.
- Disconnect and reconnect wired or Bluetooth audio.
Android
- Use the media output switcher to choose the intended device.
- Check media volume separately from ring and alarm volume.
- Review Accessibility audio balance and mono settings, then reconnect the device.
Verify the repair
Change one setting or connection, then repeat the same controlled signal. If the symptom follows the hardware to another source, physical service becomes more likely.
