It is likely, but the same set of utilities work on Linux Mint flawlessly.
I've tried a fair bit of troubleshooting with no luck and eventually given up on getting it running on XFCE.
The versions are the same? Maybe its time for a bug report to blueman or your distro.
I mean Linux Mint is a distro while XFCE is a desktop environment... I'm sure if you installed XFCE on Mint your bluetooth earbuds would work just fine, and that bluetooth would be broken on your current distro regardless of what desktop environment you used.
Yes, and I will consider the Linux Mint XFCE edition at the next fresh install opportunity.
