Dude, I don't think it's the headphone, it's the jack. Can you see if your replacement headphone works when it's plugged in somewhere else?
If it can be used, it is the problem of the phone headphone jack, generally there is a fault in the place. It is generally the contact problem between the jack and the motherboard or the oxidation problem of the jack, and the oxidation of the jack will affect the contact between the headphone and the jack
