For sale is a pretty new Neumann KM 184 stereo pair of cardioid small diaphragm microphones. They were used only once in a smoke free studio.

the Neumann KM 184 is a dependable, transparent-sounding small-diaphragm condenser microphone. Thanks to its non-modular design, the microphone is available at an attractive price without sacrificing any of Neumann's renowned engineering, and its combination of a frequency-independent cardioid polar pattern and a smooth linear frequency response provides effective protection against feedback. With genuine 28-bit resolution and an impressive impulse response, the KM 184 is an excellent choice for a wide range of applications in both studios and on stage. The slight treble boost of approximately 3dB between 5 and 15kHz makes the recorded signal sound fresh and easier to integrate into the mix. The pair on offer here is perfectly matched and is therefore particularly suitable for stereo miking. The only difference between the KM 184 mt model here and the classic nickel-finish KM 184 is the mt's matte black finish.
