Avoiding hearing damage Permanent hearing loss may occur if earbuds or headphones are used at high volume. You can adapt over time to a higher volume of sound that may sound normal but can be damaging to your hearing.

ÂLimit the amount of time you use earbuds or headphones at high volume.
ÂAvoid turning up the volume to block out noisy surroundings.
ÂTurn the volume down if you can’t hear people speaking near you.
