Safety instructions
Attention! High volume!
This is a professional pair of headphones. Commercial use is subject to the rules and regulations of the trade association responsible. Sennheiser, as the manufacturer, is therefore obliged to expressly point out possible health risks arising from use.
This system is capable of producing sound pressure exceeding 85 dB(A). 85 dB(A) is the sound pressure corresponding to the maximum permissible volume which is by law (in some countries) allowed to affect your hearing for the duration of a working day. It is used as a basis according to the specifications of industrial medicine. Higher volumes or longer durations can damage your hearing. At higher volumes, the duration must be shortened in order to prevent damage.
The following are sure signs that you have been subjected to excessive noise for too long a time:
yYou can hear ringing or whistling noise in your ears!
yYou have the impression (even for a short time only) that you can no longer hear high frequencies!
