Follow these checks in Audio Fix →

When this guide applies

Exact WH-1000XM4 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.

Is the headset powered on?

Passive cable listening with power off does not establish active noise cancellation.

effect

Can you confirm the intended mode and compare the effect?
