Follow these checks in Audio Fix →

When this guide applies

Exact WH-CH730N using its documented controls. No factory reset, pairing deletion, physical repair or guessed firmware minimum. Noise cancellation is reduced ambient sound, not total silence. Use a safe stationary environment.

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 power. Follow the link that matches what you actually observe. Alternative branches are not a single sequence of actions.
