Solving Freebuds 3 volume problem on Linux

My freebuds 3 had a very low volume on Ubuntu 18.04 until I saw this answer. So running the following command 4 times resolved the issue

dbus-send --print-reply --system --dest=org.bluez /org/bluez/hci0/dev_<mac_address_of_headphones> org.bluez.MediaControl1.VolumeUp

Just note that the mac address should be seperated with _ underscore rather than : which you may find in the bluetooth settings.
