● Listen Responsibly
To avoid hearing impairment, please make sure to turn down the volume of the music player before
connecting the earphones. After putting the earphones into/onto the ears, turn up the volume
gradually until to a comfortable listening level. Noise level is measured in decibels (dB). Exposure
to 85dB or higher noise will lead to gradual hearing impair- ment. Please supervise your usage and
the hearing impairment is a function of loudness against time.
The louder the sound is, the shorter you can be exposed. The softer the sound is, the longer you
can listen.
