Follow these checks in Audio Fix →When this guide applies
Two intended sources already paired to this exact speaker pair.
Connection scope: Bluetooth. Symptom: Switching between devices 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
Start at step-0. Follow the link that matches what you actually observe. Alternative branches are not a single sequence of actions.
step-0
Is the destination source already paired?
Do not confuse another KEF pair with the currently selected speakers.
Look for: Confirm the stated prerequisite or observation; unknown is not a fault diagnosis.
- If Yes / this check is completed → Do you accept interruption of the current Bluetooth audio?
- If No / this cannot be confirmed → Keep the observation for manufacturer support
- If I do not know / cannot check → A required observation is unknown

step-1
Do you accept interruption of the current Bluetooth audio?
The next short rear-button press disconnects the current source; no pairing deletion is intended.
Look for: Confirm the stated prerequisite or observation; unknown is not a fault diagnosis.
- If Yes / this check is completed → Briefly press the Primary Bluetooth-pair button
- If No / this cannot be confirmed → Keep the observation for manufacturer support
- If I do not know / cannot check → A required observation is unknown

step-2
Briefly press the Primary Bluetooth-pair button
Use rear B once; discovery becomes available. Do not hold or press Reset.
Look for: Perform only the stated check, then confirm whether it could be completed.
- If Yes / this check is completed → Does the intended second source connect and play?
- If No / this cannot be confirmed → Keep the observation for manufacturer support
- If I do not know / cannot check → A required observation is unknown
