If you work in high noise, or need to be hands-free around machinery, Earmark radio Headsets make you truly productive. These Headsets provide the best combination of performance, durability and comfort available. Battery compartments are sealed against moisture and dust. Rated Intrinsically Safe by Underwriters Laboratories, the Series 4 also operates on rechargeable NiCd cells when called upon.
Comfort means a lot.
We try hard to make you as comfortable as possible when you use Earmark radios. The Series 4 Headset features a Vertical Support Strap to distribute the weight evenly, across the top of your head, and a back strap to keep the Headset from falling when you bend forward. By moving the headband you can vary the load over the course of a day. Earmuff covers help avoid perspiration problems. Hard-hat mounts snap in, in place of the headband.
