Wanted to ask if you might know how to use 2 Bluetooth headphones simultaneously on one device.
So listen to music at the same time
Bluetooth has a strict 1-1 protocol. You can connect a Bluetooth device to multiple devices but not at the same time. Thus, it is always tied to a device. You need a Bluetooth splitter to work around the problem, but if you really need it is another question. https://www.sir-apfelot.de/bluetooth-splitter-6842/
