Configure Manual Call and Media Audio Split

Since the WH-1000XM3 hardware does not support simultaneous multipoint media streaming, use this manual configuration to split call and media duties between two devices.

1. Pair both source devices with your WH-1000XM3 headphones.
2. Ensure any voice assistants (Google Assistant or Amazon Alexa) are disabled on both devices to prevent connection conflicts.
3. Connect the first device (e.g., your smartphone) to the headphones.
4. Access the Bluetooth settings on the smartphone, select the WH-1000XM3, and uncheck 'Media audio' so that only 'Call audio' remains enabled.
5. Disconnect the headphones from the first device.
6. Connect the second device (e.g., your laptop) to the headphones and ensure it is configured to use the headphones for 'Media audio' only.
7. Reconnect the first device. The headphones will now prioritize the laptop for media and the smartphone for incoming calls.
