Start with a clean baseline
Input and output are separate paths. Prove left/right playback and microphone capture independently before blaming Bluetooth, the app or the entire headset.
Live evidence
Relevant checks
Bluetooth LE Browser TestOpen the browser Bluetooth chooser for compatible Bluetooth Low Energy devices in supported environments.
→Gamepad Controller TestTest browser-detected controller buttons and analog axes.
→Keyboard TestPress keys and verify that the browser receives the expected keyboard events.
→Mouse Button TestVerify left, right, middle, and extra mouse button events.
→Left Right Speaker TestPlay left and right channel tones separately.
→First sequence
Do the high-signal checks before risky changes
- 1
Identify the device profile: audio, input, controller or BLE sensor
- 2
Pair in the OS when appropriate
- 3
Run the relevant DeviceOK function test after connection
Decision points
What the result should change
If playback passes but microphone failsKeep the diagnosis on input selection, headset profile, mute/gain or microphone hardware.
If only one channel failsCompare cable/earcup/driver and balance settings rather than reinstalling all audio drivers.
If browser audio passes but conferencing audio failsPrioritize the conferencing app's device routing and processing.
Browser can help check
- Test browser-visible functionality after OS pairing
- Request compatible BLE devices through Web Bluetooth
Browser cannot prove
- Replace OS Bluetooth pairing for every profile
- Inspect radio RF quality professionally
- Access classic audio profiles through Web Bluetooth
Repair boundary
Know when to stop browser troubleshooting
- High playback levels can damage hearing; use moderate levels during tests.
- Bluetooth codec/profile negotiation is not fully exposed to websites.
- Battery swelling or heat in wireless audio devices requires service/disposal guidance.
Used-device inspection
What to verify before paying or signing off a repair
- Left/right and frequency sweep at safe level
- Microphone recording and mute controls
- Wired/wireless connection modes and charging behavior
