Insulated devices like this don't have ground! They don't touch or have a pathway to mother earth "Ground" You often have a Faraday cage to Insulate/Isolate the internals from exposing people to danger or signal interference.
Chassis Ground/Logic board Ground Plane is the common within, it's the mounting point for the 'Other' side of the connection one needs to supply to complete the circuit to the power services.

Ok, so im trying to attach a 3.5mm aux to the audio output of this bluetooth earbud. I can see where some wires will go, but i cant figure out where on the board to attach the two ground wires coming from the 3.5mm plug. Any suggestions?
