Headphone Jack Port Replacement for MacBook Pro

Hey! 🙂

I have a eary 2011 MacBook Pro 13" i5 and I noticed that when inserting my headphones into the headphone port it is not as firm as it was before (This happened after using a splitter). I haven't had any issues with audio so far but as time goes by and due to usage there is a chance that the jacks might not fit in as firm as before so I'm wondering it there would be replacement ports or is it part of the mother board? 😕
