I had the same problem with my old phone. Every earphone I used was not working. Turned out that the little metal reseptors inside the 3.5mm jack hole were bent and couldn't percept the earphone. You might need to chance your jack socket.

Welcome to Android Central! I agree with Ahmetozefe. First, check the jack to see if there is any debris in there. Use a can of compressed air to blow it out. If it's completely clear and still doesn't work, then bring it to a repair shop to replace the headphone jack.
