I believe that many people will subconsciously raise their voices when listening to songs with headphones.On Ear Active Noise Cancelling Headphones  If they are not careful, the mobile phone will pop up this prompt. Why is this?

This is the ear with specialized hearing "receptors" -- the ciliated cells in the cochlea. We hear sound because the receptors are stimulated, and the cilia vibrate in response to the sound. Once the cilia swing too much, it is easy to damage the hearing.

Long-term use of headphones at high volume will damage your hearing in the high-frequency sound wave part (2000-4000 Hz). Excessive stimulation of the cochlear cilia will lead to reduced sensitivity, and will damage hearing in the long run, and this damage is gradual and often overlooked, so mobile phone manufacturers will set a prompt for a healthy volume to protect our hearing.

If the headset does not have an active noise reduction function, many people will subconsciously turn up the sound when exercising or going out to take a subway bus to block the noise from the outside world. Usually, the volume may be turned to 60, which is just right. , but because the surrounding environment is too noisy, it needs to be adjusted to 80 or even higher to hear the music in the phone clearly.
