That's what I get when I try to connect -- a less than helpful error 
message. The same error message as quoted before appeared in the systemd 
journal when I make the connection attempt.

And the output of info <addr> is quoted above as well. I am wondering if 
among the UUIDs listed should be a2dp-sink, and since we are not getting 
it it is getting booted. But as we know from the journal entry, 
a2dp-sink protocol is "not available" -- and I think that remains the 
issue to fix to get this working.

Overall I am inclined to think something is misconfigured / broken / 
missing in the _computer_'s bluetooth setup, not the headphones -- as 
the headphones work fine with other devices eg my iPhone, and for anyone 
coming late into the conversation they also worked with this computer 
too until about 2 weeks ago now.
