When this guide applies

Exact Ultimate Ears BOOM 4. Exactly two same-model units; no visibility/privacy setting is changed or update started. Bluetooth source context; no reset or saved-pairing deletion is prescribed.

Connection scope: Bluetooth. Symptom: Stereo or party speaker linking 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.
