I hate speakers with open bluetooth. I’d rather have to press a button than let anyone in range potentially have control, partially for shit like this, partially just because someone looking to connect to their own device might pick mine on the list if theirs isn’t showing up.

My soundbar is very good at always showing up on that bluetooth device list and I have had neighbours randomly connect to it. I’ll usually turn the bt off at that point, but it’s usually on because I use it sometimes. Just wish it had some sort of security instead of being designed for people who might have enough trouble getting the power on.
