When this guide applies

Control app available, with the correct speaker pair selected.

Connection scope: Bluetooth. Symptom: Buttons, touch controls or wear detection 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 step-0. Follow the link that matches what you actually observe. Alternative branches are not a single sequence of actions.

Is Bluetooth the current input?

HDMI transport controls differ; do not use the TV media path here.

Look for: Confirm the stated prerequisite or observation; unknown is not a fault diagnosis.

step-1

Is KEF Connect controlling this exact pair?

The app may list several nearby pairs; a nearby listing is not necessarily the current controllable pair.

Look for: Confirm the stated prerequisite or observation; unknown is not a fault diagnosis.

step-2

Use app Play/Pause once

Request one playback-state change on the Bluetooth controls screen.

Look for: Perform only the stated check, then confirm whether it could be completed.

step-3

Does the actual source player change state?

Remote source/volume controls do not prove every app transport function works with the source.
