The FG Series microphone is the world's smallest electret condenser microphone. Its cylindrical shape and compact size provide for superior fit rates. The FG can also be used in directional applications as a matched omni-directional pair. The BFG is an improved version of the FG microphone and offers enhanced PFA performance and power-on reset for instant settling time. Its electrical high pass filter enabling custom corner frequencies makes the BFG ideal for use in directional applications as a matched omni-directional pair.
Knowles is the originator of balanced armature technology which they apply to their receiver, specialty transducers and hearing aid products. Knowles is also a market-leading manufacturer of MEMS microphones, electret microphones, voice processors and acoustical component accessories.
