Dual Input Heavy Duty Over-The-Head Noise Cancelling Headset


The Heavy Duty, Noise Cancelling Headset has been manufactured with a positive-action PTT button on one of the earmuffs. You can choose the optional Inline-PTT cable which also has a heavy duty positive-action PTT inline, or can go with the standard Earmuff-PTT cable. The headset has been designed with strain relief, meaning that any pressure is placed directly onto the Kevlar reinforced cable. If the cable is caught in machinery it will give way preventing damage to the headset. A new cable would then be purchased rather than an entire headset.

The replaceable cable also gives the flexibility to continue to use your headsets if you upgrade your fleet of radios, as you would only have to purchase the relevant cable.

The Dual Input headset allows a radio user to listen to two radios (of any make/model) simultaneously. It has Earmuff PTT buttons for each radio (one red, one black on each side) and has the option for both radios to use the Inline PTT cable.

They are designed for all industry types but are particular favourites in motor racing, production, manufacturing, mining and construction applications.
