The Series 9900 Wireless Intercom System is the perfect
solution for wireless intercom communications in
demanding environments, such as airline/airport operations,
fire/rescue applications, marine intercom, or any application
requiring robust, reliable and secure communications in and
around high-noise areas.
The H9930 is a wireless, marine-grade version of our legacy
noise-attenuating headsets, providing the same rugged
dependability but designed for use with David Clark
Wireless Belt Stations.
It is a dual-ear, over-the-head style communication headset
incorporating a noise-canceling dynamic microphone which
is optimal for extreme noise environments up to 125 dB
(above which a mic shield may be considered, see H9910).
With superlative performance and unsurpassed comfort
features allowing for ease of use over long work shifts, the
H9930 is an ideal headset choice for use where high noise
levels make it difficult to communicate and effective hearing
protection is desired.
