Sony ULT WEAR: check two-source playback handover

Confirm two actual connections, then use the ULT guide’s pause-first handover.

When this guide applies

Exact ULT WEAR with two Bluetooth sources. No simultaneous audio mixing is promised. The model guide documents LDAC being unavailable in two-device mode; app names may differ after renaming to Sound Connect.

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.

What owners have reported

These are public, self-reported experiences. They help explain the order of checks and the limits of a guide. They are not controlled tests, proof of a cause, a success rate or a substitute for the manufacturer instructions above.

User-reported ULT WEAR owner discussion of LDAC and connection settings

The owner describes inspecting multipoint and sound-quality settings while investigating LDAC that stayed on AAC. The later report concerns the phone’s codec control.

How this informs the checks: Explain the independently documented ULT LDAC/two-device choice and then ask for actual connection and audible handover observations.

Limits: This is configuration-tradeoff context, not a reported multipoint handover test or evidence that all sources switch successfully.

Checks and possible outcomes

Start at paired. Follow the link that matches what you actually observe. Alternative branches are not a single sequence of actions.

paired

Are both intended sources already paired?

A saved pairing is not yet an active connection. If either is unpaired, use Sony’s pairing instructions first.

Look for: Choose only the observation you can confirm.

Connect the first app-equipped source

On the source with the Sony app installed, establish the Bluetooth connection to ULT WEAR.

Look for: That first source is actively connected before you change two-device mode.
