Usage
To avoid hearing loss, please set the playing equipment volume to
minimum before connecting the headphone (or earphone). After wearing
the headphone (or earphone), increase the volume to a proper level. The
noise is calculated by dB. The noise above 85 dB leads to hearing loss.
Please pay attention to your operation habit. The relationship of volume
& hearing time and hearing loss as below: the higher the volume is, the
shorter the hearing time should be. The more proper the volume level is,
the longer the hearing time can be. The long time hearing at high volume
level leads to permanent hearing loss.
