The EM is the most popular omni-directional microphone offered. The superior performance of the low noise EM makes it the choice of hearing instrument manufacturers for all hearing instrument sizes. The EM can also be used in directional applications as a matched omni-directional pair. The BEM is an improved version of the EM microphone. It offers enhanced PFA performance, as well as power-on reset and an electrical high pass filter. The BEM is ideal in directional applications as a matched omni-directional pair.
