When this guide applies

Exact WH-1000XM4 with two Bluetooth sources. Two-device mode excludes LDAC on this model. This is sequential playback switching, not mixing simultaneous audio.

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 Mixed WH-1000XM4 multipoint handover experiences

The thread describes failed handover with different phone/computer combinations. Replies report mixed outcomes after pausing playback, manual disconnection or software/driver changes.

How this informs the checks: Supports asking users what they hear after each check rather than promising automatic switching from a feature list.

Limits: Reports span old versions and conflicting outcomes. They establish neither a universal workaround nor a currently fixed firmware version.

Checks and possible outcomes

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

ldac

Is two-device mode the behavior you want?

WH-1000XM4 uses AAC or SBC with two-device mode; LDAC cannot run in that mode.

Look for: Choose the observation you can confirm.

pair-a

Pair source A

Complete Bluetooth pairing with the first source.

Look for: The source has a pairing record for WH-1000XM4.

Pair source B

Complete Bluetooth pairing with the second source.

Look for: Both sources have pairing records.

Enable the two-device setting

Enable Connect to 2 devices simultaneously in the Sony app.

Look for: The setting is enabled.

both

Does the app show both sources connected?

Inspect connected devices; do not equate two saved pairing records with two active connections.

Look for: Choose the observation you can confirm.

Pause source A

Pause the source that is currently playing.

Look for: The first playback is paused.

Can you hear source B?

Persistent handover failure needs a further configuration-specific check.

Possible result

Choose the LDAC procedure instead

For WH-1000XM4, LDAC requires the two-device setting to be off. Change the symptom to the missing-codec check if LDAC is your priority.

    Possible result

    A required observation is missing

    Check the exact model, OS/app version and the linked official instructions. A missing or different screen is not a negative capability result. Stop this path until that observation is known.

    Look for: Report your own outcome separately. Reaching this screen does not mean the issue is solved.

    insufficient data

    Reaching this result does not mean the issue is solved. Only your own feedback can report improvement.

      Possible result

      The next step needs official support

      These checks did not establish a working setup. Use the linked Sony instructions or support with your exact model, source and versions. No hardware or driver fault has been diagnosed. Factory initialization is outside this flow; it removes stored pairing information.
