bluetoothctl 5.76 fails to connect after pairing on broadcom card

I am trying to connect my (up to date) arch linux with my headphones.
It seems that there are a lot of questions about the topic, and I have tried many ideas:
I have tried rebooting, removing the /var/lib/bluetooth directory, reinstalling the packages, removing the device and retrying to pair+connect, restarting the services, none has helped me.

Bluetooth card is the following (from lsusb): `ID 0a5c:4500 Broadcom Corp. BCM2046B1 USB 2.0 Hub (part of BCM2046 Bluetooth)`
I installed bluez-hid2hci to make the device detectable.

On another occasion when I start or stop pulse audio with

 pulseaudio --start 

I am getting:
