Heavy Duty Behind-Head Noise Cancelling Headset (no cable)


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.

This headset is sold as a replacement for a broken or damaged headset as it doesn't come with a cable.

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