Headphone Issues - Only left side works

I have not been able to get my headphones to work properly. Only the left earbud works and I have tried this on three pairs (including bluetooth ones). I had an iPhone 11 and it did this and then I got the iPhone 13 Pro and it is continuing to do this. I have adjusted the audio settings and even reset my settings on my phone and I still cannot get it to work. I am not sure what to do. Asking for any and all suggestions. Thank you!
