OK, so on the headstock? You have something loose. If it’s up near the headstock, it’s most likely One of the hex nuts that hold the tuner to the headstock. If it’s not that, something else in the vicinity is loose, because that’s vibration that shouldn’t be there. Hit a low E open and move your ear around the guitar to help isolate where it’s coming from.
I had a similar rattle on my electric guitar a while ago, turned out the plastic thingy that covers the truss rod nut was a bit loose and I just had to tighten the screw.
