All Bluetooth Audio device
Listening to music at high volumes for long periods can lead to hearing
problems. We do not recommend using these headphones at maximum
volume, particularly for long periods of time.
To protect your hearing, turn down the volume of your music player
before connecting your headphones. After putting on the headphones,
gradually turn up the volume until you reach a suitable level. Sound
levels are measured in decibels (dB). Exposure to sound 85 dB or
above may result in gradual loss of hearing. Monitor your use. Hearing
loss depends on the intensity of the sound and the duration. The higher
the volume, the less your exposure capacity will last. The lower the
volume, the longer your exposure period can be.
Be responsible: pay attention to your environment (acoustic) when you
are wearing your headphones and listening to music or the radio.
Avoid hazardous behavior that may cause an accident for you or
somebody else (pedestrians, motorcyclists, drivers, cyclists) or cause
damage to property when you are wearing your headphones.
Lezun would like to inform you that the use of stereo headphones is
strictly forbidden when driving a motor vehicle. Lezun also
recommends not listening to music or the radio through your
headphones when riding a bicycle, a scooter or any other means
of transport for which it is not compulsory to wear a helmet. Lezun
can not accept any responsibility if you choose to ignore these warnings.
