The Directionalplus utilises a sophisticated Directional Microphone system combined with the proprietary Personal Noise Reduction technology found in the Natura 2 SE. These two technologies emphasise speech from the front and reduce noise originating from all directions, while also minimising noise typically associated with directional microphones. Also features second-generation DSP technology, expansion technology to minimise ambient noise, switchable directionality, and audible alert tones for low battery.
