Update again for Ubuntu 17.04
I was having connectivity issues again after rebooting my laptop. I had to change
Enable=Socket back to
Disable=Socket. Furthermore, I had to use Blueman to "Trust" the headphones to allow reconnection without setting the headphones up everytime I turned them off and back on. However, I will leave the update below in place, just in case. As it seems to help me overcome my issues initially.
