Weird sound issues on Samsung Note 5

[AC Question]

I have sennheiser HD 598 Heahphones and they work perfectly fine with my note 5. When i plug in the earbuds that came with my phone, or my other headphones with a mic attached, sound only comes out of the left ear. Is this a problem with the mics? I know for a fact that at least one of the other headphones aren't broken, so its not their wiring, ect. Not many people seem to be having this problem.
