Trusted, paired bluetooth headphones won't auto-connect

I've followed the "Bluetooth Headset" ArchWiki article and what I've achieved is that I can turn on the headphones and type `connect 00:1D:43:A0:04:5B` in `bluetoothctl` and the headphones are connected and I can listen to music.

The problem is that I have to connect *manually*. How do I make the connection establish automatically?

When the headphones are turned on `systemctl` reports:

[CHG] Device 00:1D:43:A0:04:5B Connected: yes
[CHG] Device 00:1D:43:A0:04:5B Connected: no

i.e. the heapdhones connect and immediatly disconnect. Here is the `hcidump` of this happening:

Is this a hardware issue? These are some no-brand "deleyCON" headphones. Thanks for reading
