Paint can clog the device’s moving parts or ventilationopenings and prevent proper operation.Responsible ListeningCaution!: Avoid potential hearing loss.Damage to hearing occurs when a person is exposed to loud sounds over time. Therisk of hearing loss increases as sound is played louder and for longer durations.Prolonged exposure to loud sounds (including music) is the most common cause ofpreventable hearing loss. Some scientific research suggests that using portableaudio devices, such as portable music players and cell phones, at high volumesettings for long durations may lead to permanent noise-induced hearing loss. Thisincludes the use of headphones (including headsets, earbuds, and Bluetooth® orother wireless devices). Exposure to very loud sound has also been associated insome studies with tinnitus (a ringing in the ear), hypersensitivity to sound, anddistorted hearing. Individual susceptibility to noise-induced hearing loss andpotential hearing problem varies. Additionally, the amount of sound produced by aportable audio device varies depending on the nature of the sound, the devicesettings, and the headphones that are used. As a result, there is no single volumesetting that is appropriate for everyone or for every combination of sound, settings,and equipment.You should follow some common sense recommendations when using any portableaudio device:• Always turn the volume down before plugging the earphones into an audio source.• Set the volume in a quiet environment and select the lowest volume at which you can hearadequately.• Be aware that you can adapt to higher volume settings over time, not realizing that thehigher volume may be harmful to your hearing.
