Risks associated with excessive volume levels
Be careful when using headphones. Audio listening at high volume can harm the
user’s auditory system. Do not use headphones at high volume levels, otherwise
you will damage your hearing and possibly disturb other people. Even if the
headphones are designed to enable you to hear external noise, never turn the
volume up so high that you cannot hear what is going on around you. Please
note that ambient noise can be perceived in a different and unfamiliar way.
Do not use headphones in hazardous situations, e.g. when driving or riding a
bike, working with machines or other situations which require your full attention.
The sound may distract your attention or prevent you from being aware of what
is happening around you.
