Why is the volume of music played by the POCO X7 Pro earphones low?

The low volume you are experiencing with the POCO X7 Pro earphones is due to regulatory restrictions on the maximum sound pressure for headphones. These regulations are in place to protect consumers' 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 improve your perception of the volume, as background noise can interfere with your listening experience. If the volume still feels insufficient, you can also consider adjusting the sound settings or sound effects for better clarity and louder output.
