Why does the music volume from the POCO F7 Pro sound low when using earphones?

The low volume you are experiencing when using earphones with the POCO F7 Pro is due to regulatory restrictions on the maximum sound pressure for earphones. These regulations are in place to protect your hearing and prevent potential damage caused by excessively loud audio levels. If you feel that the sound is too low, you can try turning up the volume.
Additionally, listening to music in a quiet environment can help to improve your perception of the volume, as background noise can interfere with your listening experience. If you still feels that the volume is insufficient, you can also consider adjusting the sound settings or sound effects for better clarity and louder output.
