SUPREME PRO COMMUNICATIONS HEADSET PRODUCT FEATURES
Thank you for choosing this MSA hearing protector! This may be the fi rst time you have chosen
an MSA product, or you may already be familiar with our models. We are proud to be able to
protect your hearing. MSA's professional technology helps ensure that you are never isolated
– but always protected.
The MSA Supreme Pro Communications Headset is a hearing protector equipped with
electronics for reproducing ambient sound. The electronics include two externally mounted
microphones that capture the ambient sound (Fig A). This sound is then reproduced by
speakers inside the hearing protector. The sound is reproduced in stereo to preserve or
improve direction location. Sound reproduction is limited to a maximum of 82 dB(A) to prevent
damage to hearing. This function is intended for use in situations where there is a need to
hear ambient sound, e.g. hunting, shooting, warning signals, conversation, traffi c, etc. Supreme
is one of a series of products developed to improve your working environment – and your
leisure time if you are exposed to noise.
