Manufacturer-documented Reviewed 2026-11-09 · Revision 1
Follow these checks in Audio Fix →When this guide applies
Android connected product, safe stationary comparison; no noise-attenuation test.
Connection scope: Bluetooth. Symptom: Noise cancellation or listening modes aren’t working.
This is a documented check, not a diagnosis of your equipment. The model name does not confirm the selected input, mode, software or connected partner.
If your exact model or a required setting is unknown, use the “I don’t know” branch below. Do not apply a similarly named model’s instructions.
Checks and possible outcomes
Start at check-0. Follow the link that matches what you actually observe. Alternative branches are not a single sequence of actions.
check-0
Are both earbuds comfortably and correctly worn?
Do not cover the outer microphone area when checking noise modes.
Look for: Confirm the stated observation; do not infer an unavailable detail.
