To design a headset which maintains speech intelligibility on one hand, doesn’t interfere with any headgear on the other, and is of very small size in addition, our engineers met the challenge by merging all functionalities in one single earpiece. One inner and one outer microphone within primero provide the sophisticated electronics with the required signals. primero is especially useful in circumstances where clear communications in hazardous environments is needed and obstructive headgear makes the operation even more difficult.
