Pairing is not the same as connecting
A product may remember several paired devices while connecting to only one at a time. Multipoint support can allow more than one active connection, but the details depend on the model. Do not infer the feature from a recent Bluetooth version number or from a listing that merely says multiple devices are supported.
Write down the switching sequence you need: music on a laptop, a call on a phone, then a return to the laptop. Look for instructions describing that sequence. If the manual says to disconnect one source before selecting another, the product may still suit occasional use, but it will not provide the automatic handover you imagined.
Check what interrupts what
Two connections do not necessarily mean two audio streams mixed together. A call may take priority, or playback on one device may need to stop before the other is heard. Check whether notifications interrupt listening and whether playback resumes afterwards. Behaviour can vary between the headset, operating systems and applications.
If a companion app enables the feature, confirm that you can install it on a supported device. Some settings or audio modes may change when multipoint is enabled. Read the relevant model instructions rather than assuming every product from the same brand makes the same trade-offs.
Test the ordinary return journey
Pair the intended devices in the recommended order, then test the sequence with non-sensitive audio. Pause one source, start the other and check a call where appropriate. Make a note of the selected input and output devices if the computer continues to use its speakers or built-in microphone.
Also test reconnection after the product has been switched off. A device that reconnects to the last nearby phone may behave differently when the laptop wakes first. Keep the manual's reset procedure available, but do not repeatedly reset everything before checking which source is still playing. Choose according to the transitions you perform each day; an easily reached source button can be more predictable than automatic switching that does not match your habits.
