Responsible for your hearing
To avoid hearing loss, turn down the volume of the music player before wearing headphones. After
putting on the headphones, slowly adjust the volume to a suitable level. The unit of measurement
for noise is (db). Long-term exposure to 85db or higher noise environment may cause hearing loss
gradually. Monitor usage; hearing loss is the result of too much noise and time. The louder the
sound, the more time to reduce exposure to noise. The softer the voice, the longer you can listen.
Please visit the Consumer Electronics Association website (www.ce.org) to learn how to establish
a safe listening level and review other important safety guidelines. For important information on
how to prevent noise-induced hearing loss (NIHL) and a complete list of what noise can cause
hearing loss, please refer to the website of the Foundation for the Study of the Hearing Impairment:
