My bluetooth headphones connect to my macbook pro when come home from work and my laptop is sitting on the kitchen table. My headphones tell me "two devices connected" when I walk in the door.

Although it seems like bluetooth _should_ be shut off by devices when not in use, I doubt most devices actually do that.

I'd really like to understand this deeper: are you sure your macbook was hibernating, even if it was closed? Are you sure the proximity advertisement came from the laptop? Usually it is the iPhone doing it.

I've seen that in airports and malls, more than 90% of the advertisements around are iPhones (Android doesn't do BtLe advertisement) and Windows computers (from the shops and stores). A small minority are beacons and wearables (iWatch, Fitbit, etc.) In libraries sometimes I can see Macbooks, but they all are non-hibernating.

My headphones are only paired with my macbook and my android phone. I always am walking with the headphones paired with my phone, so that's one of the two devices. The only other device is my macbook pro, that is often sitting on the kitchen table with it's lid closed, and unused for several days, and yet this happens every day. I obviously don't know what exactly is going on, but if they can "connect" then presumably something about the bluetooth is still functioning.
