Skullcandy hesh 3 possible problem

[ors.24102002]

Hey, I got some Skullcandy Hesh 3 recently. They are brand new, however, the supposedly "Middle" audio (the one that should sound exactly the same in both of your ears) seems to be a little bit to the right. When I tested these headphones at a store they were completely normal (on the demo song that was put).
Should I worry about this problem?
Do these headphones really sound like this?
Thank you

Oh god I'm sorry
Made an auditory test and I'm going deaf in only my left ear

Thanks, everyone anyways
