Change ringtone on bluetooth headset?

I'm now working from home for myself instead of a company (yeah me)
I finally bought a bluetooth device so I can work and talk at the same time. (I totally look like a telemarketer but luckily no one has to see me)
It's an over the ear boom mic job, and it works great.
The thing is the ringtone in my ear sucks.
I've looked through all the places I can think of to change the tone for the bluetooth, but I can't find anything.
Am I stuck with this awful dixieland music?

Thanks
:on-phone:

Is there any way to set it on the headphone, itself?
