When this guide applies

Exact SOUNDPEATS H3; two Bluetooth sources that can each pair with the earbuds. LDAC cannot operate with dual-device mode. No mixing of two audio streams or automatic call-app behavior is promised.

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.

Possible result

A required observation is missing

Do not guess the setting or support. Open the linked documentation and check the exact source model and the relevant screen. If the control differs, record the app/OS/firmware version for the manufacturer; this guide cannot confirm a version-specific path.

Look for: This is the outcome of the checks, not a claim that your problem has been solved.
