Reply to S4 sound coming out louder on one side of headphones

Ok so ive been having this issue now for a few weeks, I own an s4 and the music is clearly coming out louder on one side of my headphones. Now ive tried this on two different sets of headphones so I know they arnt broken, ive messed around with the headphone settings on traktors main screen, googled it 1000 times and im totally at a loss, like all DJ related issues its probably the most simple thing ever to fix and im an idiot but I really could use some help on this one thanks!
