I phone not supporting headphone cord

I have an I phone so I’m using a cord to be able to use headphones through the charging port it’s weird I can charge my phone with any I phone charging cord just

fine but through the same port it won’t support this headphone cord so I can use cord headphones I wish I phone had a regular headphone port because my I phone doesn’t have a headphone jack port and it works for a few seconds then says this device is not supported by you’re I phone? How can I fix that? Usually I would use wireless headphones but mine broke and I have no funds to buy more also these are more comfortable. I would play my show I’m watching out loud but it’s late and my fiancé is asleep I am pregnant 26 weeks first time being pregnant and also up with a bad toothache at 3:33 am so I’m trying to distract myself ugh my toothache is so painful any tips for that would help to thank you!
