Probably the wires are broken inside the cable from long use and constant wiggling of the cable around the plug, which is normal. A typical malfunction. The copper wire or wires looses permanent conduction due to mechanical stress, but when you twitch it it may recconect for a while and conduct the signal current to the earphones for the moment. This is the most typical thig if the phones woudn't work with many appliances alike, otherwise it could be some socket thing or output stage in a particular device to blame and not the headphones themselves. This could only be fixed by cutting the cable off a few cms up from the plug and soldering in a new same type plug in place after checking the wiring to the phones with a multimeter. I assume it's a mini jack plug connector TRS or TRRS perhaps. See here for https://en.wikipedia.org/wiki/Phone_connector_(audio) So that's that I'd think. And would be most probably fixable the way I outlined, but it requires some skill.
