Bluetooth is very insecure. Almost all the security comes from needing devices to be close together. And even the latest standards/devices won’t be that secure because the goal of the tech is simple easy connections with low latency. Encrypting your music stream would piss away battery power while you listen to Trump ASMR.
As others have said, there are plenty of downgrade attacks unless your devices are basically the latest and the protocol is set to encrypted file sharing.
You mention an android phone and a Linux laptop. If you’re worried about security then use a usb cable as the gold standard, or transfer encrypted files only. If you like convenience then just look around you for anybody suspicious.
