Bose QuietComfort Headphones (2023): check two-device switching
Check both active connections and test deliberate pause-then-play handover.

Follow these checks in Audio Fix →When this guide applies
Exact Bose QuietComfort Headphones sold from 2023. The procedure switches one audio stream; it does not mix two streams or import Ultra/2nd Gen settings.
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 QuietComfort 2023 Mac/iPhone multipoint discussion
The author describes QC2023 Mac/iPhone playback interruptions and says turning multipoint off appeared to help their setup. Replies mix QC45, QC2023 and Ultra experiences.
How this informs the checks: Test documented sequential handover with observed active connections; preserve escalation if the second source remains silent.
Limits: Only the explicitly QC2023 observations are relevant. Disabling multipoint removes the two-device use case; it is not proof of a repaired handover or a general firmware fault.

Checks and possible outcomes
Start at both. Follow the link that matches what you actually observe. Alternative branches are not a single sequence of actions.
both
Are both intended sources actively connected?
Check both current Bluetooth states. Stored pairing entries alone are not active connections.
Look for: Choose only the observation you can confirm.
- If Yes → Pause source A
- If No → Check the multipoint setting
- If I don’t know / could not check → A required observation is missing

mode
Check the multipoint setting
In the Bose app, open Settings > Bluetooth Connections and turn Multi-point connection on if off.
Look for: Two-device operation is enabled.

Connect the second source
Use its Bluetooth settings to connect the already-paired headset.
Look for: Inspect both connection states.
- If I completed this check → Are both sources connected now?

Are both sources connected now?
If either remains unpaired or disconnected, resolve that connection first.
Look for: Choose only the observation you can confirm.
- If Both are connected → Pause source A
- If One or both remain disconnected → Continue with model-specific support
- If I don’t know / could not check → A required observation is missing

Pause source A
Pause audio on the source currently playing.
Look for: The first playback is paused.
- If I completed this check → Play source B
- If I cannot follow this step → Continue with model-specific support
- If I don’t know / could not check → A required observation is missing

Play source B
Start audio on the second source.
Look for: Listen for that source.
- If I completed this check → Is the second source audible?

Is the second source audible?
An observed handover is not a promise that every app or later call will behave identically.
Look for: Choose only the observation you can confirm.
- If Source B is audible → Checks completed — report your outcome
- If Source B is still silent → Continue with model-specific support
