exceed 50% of the maximum volume of your audio
device, always make sure to lower the volume
before using it and limit the use of headphones to
an hour or less per day . The use of high volume
headphones (higher than 85dB) or for prolonged
periods of time (over one hour per day) can cause
permanent hearing damage. They can be gradual

performing a hearing control and a medical
examination are the only way to diagnose any
auditory damage if you notice the following
symptoms: Brusii or buzzi and difficulty in
understanding dialogues.
- Do not use headphones when they could cause
distractions and constitute a danger (while driving
the car, cycling, walking or operating machine tools)
- Do not immerse or expose the headphones to
liquids.
