Series 3400 Headsets are designed to provide crisp, clear communications and effective hearing protection in highnoise environments. They are engineered to be compatible with David Clark Series 3100, 3400 and 3800 Intercom Systems and Series 3000 Mobile Radio Adapters.

The Model H3441 is a single-ear, behind-the-head style headset capable of affording comfort and communication clarity over long periods of time, and designed for use under protective head gear. It utilizes the M7-A electret, noisecancelling microphone, delivering excellent speech intelligibility.

The H3441 includes one ear slotted dome without earphone for hearing ambient sound. The other ear cup is noiseattenuating, providing clear isolated reception of the connected parties by either intercom or radio. A microphone on/off switch is also included.

Durable construction and quality components are found throughout the Series 3400 headsets, with enhanced comfort features for exceptional comfort in any temperature or environmental conditions. David Clark created the world’s first noise attenuating communication headsets, and continue to lead the world in delivering quality communication tools.
