When this guide applies

Exact Technics EAH-AZ100 with a Bluetooth source. The other party cannot hear you in an active Bluetooth call. Touch assignments may have been customised. Reversible checks only; no factory reset or pairing-list deletion.

Connection scope: Bluetooth. Symptom: My microphone isn’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

known-muted

Is the microphone confirmed muted?

Check the active call or documented headphone mute indication. Use the next mute-toggle control only when you can confirm the microphone is currently muted. A missing voice alone does not establish the mute state. If already unmuted, skip the toggle and check the result.

Look for: Confirm this state explicitly before continuing.
