Abstract: The invention relates to the various features of a headset design that utilizes active noise cancellation (76). This particular design has been developed to work with radio communication systems, but many features are applicable to headsets designed solely for ear protection. The unique design features of the invention allow for uninterrupted communication capability with active noise cancellation (76). The design also provides its own built-in rechargeable power supply (2) that is easily removed for recharging.
