First check that the accessory is not damaged.

Inspect the headphones, cable and connector. Do not force a damaged connection. Check whether the case prevents full insertion.
Disconnect and firmly reconnect a compatible accessory, then test at moderate volume. For debris in the connection, follow Apple’s safe-cleaning guidance without inserting objects into the port.

Use the comparison to decide what to check next.

Connect another compatible pair known to work. If that pair plays correctly, check the original headphones with their manufacturer.
If it also fails, save work and restart iPhone normally. Check for an iOS update and test again after applying it.

Still not working?

If several compatible headphones fail on the same iPhone, request Apple support. If only one pair fails, contact its manufacturer. Do not confuse this result with a Bluetooth pairing problem.
