earbuds or the earbuds are suddenly removed from your ears. After 
use, be sure to take the earbuds off your ears gently.

affect your hearing.

listening to the unit in situations where hearing must not be 
impaired, for example, while driving or cycling.

the headphones. Remember not to disturb those close to you.
