Bluetooth Headphone Controls?


I’m having trouble finding solid information on this, so I thought I’d ask.

Are Bluetooth headphone controls, like play/pause and skip supposed to be supported by the Vox Preferences extension? There’s an option for “Use headphones controls” but I haven’t been able to get this to work with my Bluetooth headphones, and from looking around the forums other people have had similar issues over the years.

I know for a fact my Bluetooth device works with iTunes, but isn’t working with Vox.

Are any Bluetooth devices supported by Vox?
If not, are there plans to add support?
If some are supported, any way support can be extended to more devices?

OS: Mojave 10.14.4 (also had this issue with all previous versions of Mojave and High Sierra)
Vox: 3.3.8
Vox Preferences: 1.5
