Ios 15.6. 1 does not support headphone ejection.

1. Make sure that the earphone is inserted correctly: When inserting the earphone, make sure that it is inserted into the earphone jack of the device and the insertion depth is appropriate. If the insertion is not deep or the earphone is unstable, the earphone cannot be detected.

2. Check whether the earphone works normally: You can test whether the earphone can be used normally on other devices. If it can be used normally on other devices, the problem lies in the iOS device.

3. Clean the headphone jack: Dust, dirt or other impurities will accumulate in the headphone jack of the device, making it impossible for the device to detect the headphones. These impurities can be removed by gently wiping the socket with a cotton swab.

4. Restart the device: There will be problems with the software of the device, which will make it impossible to detect the headset. You can try to restart the device, which can solve many software problems.

5. Update the iOS system: If the iOS device is running an old version of the system, there will be bugs or problems, which will make it impossible to detect headphones. Trying to update to the latest iOS version will fix these problems.
