When this guide applies

Exact LinkBuds Fit / WF-LS910N. Additional-source pairing; no factory reset. If no blue pairing indication appears, release the button and stop instead of extending towards initialization.

Connection scope: Bluetooth. Symptom: My devices won’t pair or reconnect.

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.
