Georg Neumann GmbH is a German professional-audio manufacturer founded in Berlin in 1928 by Georg Neumann and Erich Rickmann, best known for the condenser microphones that have been studio standards since the CMV 3 and the U 47. It has been part of the Sennheiser group since 1991, added the Klein + Hummel-derived KH studio monitors in 2010, and released its first headphone, the closed-back NDH 20, in 2019.

Two labs call it ruler-flat; the arguments are about price, rooms, and the odd unit that won't wake up.

A 4-inch box that measures like a reference monitor — the argument is whether a reference this small is enough.

A studio monitor you wear — flat on most benches, dark on some heads, and fussier about where it sits than any headphone should be.

The measurements are close to perfect; the arguments are about whether perfect is pleasant, and whether it lasts.
