Insert an ultra-light diaphragm into an acoustic field. Detect the pressure gradient as the membrane symbiotically oscillates. Move a coil of wire in the magnetic field. Generate an analogous electrical current in compliance with Faraday. Precisely phase align to create maximum attenuation at +/- 125 degrees. Install blast filter, mechanical decoupling, and recessed on/off switch. Apply non-reflective polyurethane. Compare to industry standards for tone, gain before feedback and handling noise rejection. Mic clip and protective travel pouch are included.
