After all these years, finally scripted up something to help with bluetooth connect / disconnect

bluetooth_toggle.sh

#!/bin/bash
mac_addr="XX:XX:XX:XX:XX:XX" # your bluetooth headset MAC address goes here, pactl list to get it
sink_addr="${mac_addr//\:/_}"
bluez_card="bluez_card.${sink_addr}"
bluez_sink="bluez_sink.${sink_addr}"

if bluetoothctl <<< "info $mac_addr" | grep -qi "Connected: no"; then
	echo "connecting ${bluez_card}..."
	bluetoothctl <<< "connect $mac_addr"
	sleep 5s
	pactl set-card-profile $bluez_card a2dp_sink
	echo "set-default-sink ${bluez_sink}" | pacmd > /dev/null
	pactl set-sink-volume ${bluez_sink} 0
	pactl set-sink-volume ${bluez_sink} +50% 
else
	echo "disconnecting ${bluez_card}..."
	pactl set-card-profile $bluez_card off
	sleep 5s
	bluetoothctl <<< "disconnect $mac_addr"
