Earphones plugged in, but sound comes from earphone and speakers

So as i have said, my phone suddenly started playing music out of the speakers while i was listening to music in my phone, and now when i almost fully plug in my earphones, there would be a loud static noise which comes out of the speakers (it seems to happen while detecting the earphone), please help me since i will be using the phone for the next year and i want to play games like PUBG while not disturbing others D:

Thanks in advance :D
