The Neumann UM 57 (manufactured by the East German Gefell company) is a large diaphragm tube condenser microphone capable of omnidirectional, bidirectional, and cardioid polar pattern using the same M7 capsule as in the early U 47 and M 49 microphones. The UM 57 is electronically similar to the CMV 563 "Bottle" mics of the 1930s with an EC92 triode amplifier.

Due to quality parts generally not being readily available in late-'50s East Germany, these microphones need careful maintenance and attention to bring them to their full potential and are not as valuable as other Neumanns of the era.

A 110V version of the UM 57 was released for the US market as the UM 67 and, other than operating voltage and output connector on the power supply is identical to the European microphone.
