When can we let our child use an earphone/ headset to listen to music?

I think there is no suggested appropriate age. The main consideration is the volume at which your child is listening at. Research has found that headphones above 75dB is related to permanent hearing loss. As the damage is cumulative, early exposure to loud noises may lead to premature hearing loss. When allowing the use of earphones/headphones for your child, be sure to: - Use volume control. Adjust the volume on their devices and set a limit on the maximum decibel level on the device (most devices have this setting). - Monitor the time your child spends using earphones/headphones. Limit each “session” to less than 60mins. - When your child is old enough, educate them on the dangers of listening to loud music or for prolonged use.
