MKE 2 clip-on microphone

The Sennheiser MKE 2 is a professional miniature lavalier microphone and an industry favorite among field audio engineers, broadcast engineers and film crews. With a wide frequency and high sensitivity response, the MKE 2 lavalier is developed for crucial audio reproduction of vocals and instruments. Its omnidirectional polar pattern provides an even frequency response throughout the perimeter of the microphone.

The result minimizes handling noise caused by clothing, while providing accurate, transparent audio fidelity without noise. The MKE 2 is widely favored for its superior audio quality and miniature profile. The sub-miniature yet durable design enables the microphone to be used in stage performances, video shoots, film shoots, or anywhere an unobtrusive microphone is necessary. The microphone features various terminations to accommodate wireless transmitters and connectors.

Connector 3.5 mm jack
Frequency response 20 to 20.000 Hz ± 3 dB
Max. sound pressure level 142 dB
Cable length approx. 1.60 m
Transducer principle pre-polarized condensor microphone
Pick-up pattern omni-directional
Sensitivity in free field, no load (1kHz) 5 mV/Pa, ± 3 dB
Equivalent noise level 26 dB
Equivalent noise level weighted as per CCIR 468-3 39 dB
