The Electro-Voice RE50/B is a specially shock-isolated, omnidirectional, dynamic microphone that was created for the most exacting professional applications. An advancement in shock-mounting techniques, it was designed particularly for handheld broadcast and sound- reinforcement use. All handling noise, clothing noise, and even cord shock have been isolated from the microphone element so that mechanically induced noise is greatly reduced. By use of a high-mass zinc internal acoustic chamber, shock mounted within the machined-aluminum outercasing, the RE50/B offers a degree of isolation unprecedented in omnidirectional dynamic microphones. The internal transducer uses a mechanical nesting concept all its own. Each part is nested inside another so that the transducer (head assembly) is nearly a solid structure. It is highly resistant to damage from shock.

The diaphragm is unaffected by temperature extremes and atmospheric conditions. A carefully designed integral windscreen and blast filter provides excellent protection from wind noise, excessive sibilance and annoying "P- popping." The RE50/B has a grille that bounces back to retain its shape. A four-stage pop filter prevents dust and magnetic particles from reaching the diaphragm. The RE50/B's attractive, nonreflecting, semi-gloss black finish is ideal for on-camera use.
