Performance and Safety Tips

Listen Responsibly

To avoid hearing damage, make sure that the

volume on your music player is turned down

before connecting your headphones. After

placing headphones in / on your ears, gradually

turn up the volume until you reach a comfortable

listening level.

Noise levels are measured in decibels (dB), exposure

to any noise at or above 85 dB can cause gradual

hearing loss.

Monitor your use; hearing loss is a function of

loudness versus time. The louder it is, the less

time you can be exposed to it. The softer it is, the

more time you can listen to it.

This decibel (dB) table compares some common

sounds and shows how they rank in potential

harm to hearing.
