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.
