Monster 821 Mirrors

Hello! Does anyone know if the Monster 821 mirrors have a ball joint? Seems like a daft question but it’s impossible to rotate the actual mirror head and are therefore rather redundant as can’t see a thing out of them… Can rotate from the handlebar arm but not the actual mirror itself.
Don’t think I want to move to bar end mirrors, but would be good to know if I just need to be more forceful…
Thank you
