One of the earbuds for the standard samsung headphones is not working

This happened randomly that when I plugged in my headphones that only the left side would play. After twisting the end of the headphones where it connects to the phone it would work but if I move I would have to keep twisting it until I get sound through the right bud. Nothing seems to be torn and the headphones are very clean. i also tested out different earbuds on my phone and those seem to be working fine, so it has to be a problem with the headphones. Is there any way to fix the headphones?
