Bluetooth Multipoint Lacks Official Spec, Undermining 2-Device Headphone Connections

Summary
Bluetooth SIG says so-called multipoint is not an official Bluetooth specification but a manufacturer-built use of existing profiles, helping explain why headphone switching between two devices often fails unpredictably.
Profiles such as A2DP, AVRCP and HFP can compete across a phone and laptop connection, so a call or even a notification may interrupt the audio you meant to keep playing.
That behavior varies by brand because headset makers decide their own connection logic, while mixed combinations of headphones, phones and laptops often run different chipsets and Bluetooth software stacks.
Apple and Samsung reduce that friction inside closed ecosystems by controlling both devices and the switching logic, even though they rely on the same underlying Bluetooth technologies.
LE Audio could improve transitions, fidelity and power use through newer profiles such as TMAP and BAP, but consumers still depend on manufacturers to adopt those features.
