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 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.
