Manufacturer-documented Reviewed 2026-11-09 · Revision 1
Follow these checks in Audio Fix →When this guide applies
Environmental mode and comfortable fit only. No guaranteed noise attenuation or hardware diagnosis.
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
Is the product worn securely and comfortably?
Ensure both ear cushions seal around the ears; lifting a cup prevents normal ANC operation.
Look for: Confirm the stated observation; do not infer an unavailable detail.
