Modern pocket supercomputers don't divulge anything useful about the kind of connection that is being used for Bluetooth audio so we don't know if it's using 256kbps AAC or something else instead, and it cuts out in some areas of [insert city], and when it comes back it sounds demonstrably worse.

It's an inscrutable mess.

Wires don't have these problems. Plug them in. Use them. Clean the contacts every now and then if/when they get crudded up.
