N.B.: NoiseGard ™ reduces noise and increases comfort.
NoiseGard ™ is not a medical noise protection
system!
NoiseGard ™ cannot replace an industrial ear
defender system for use in noisy environments!
Volume up? - NO !
When people use headphones, they tend to choose a higher volume than with
loudspeakers. Listening with high volume levels for a longer time can lead to
permanent hearing defects. Because the
NoiseGard ™ circuitry is reducing the
ambient noise, the headphones can be set at a correspondingly lower level leading
to more comfortable hearing conditions so protecting your hearing.
N.B.: The microphone boom is adjusted for an individual user. However, care
should be taken when doing this. Once set, the boom should not be re-adjusted.
If it is continually flexed it is liable to break.
