Regular price $56.00 Sale

A range of Knowles Acoustics miniature microphones assembled by Micronic. Very high quality sound with high accuracy and precision providing premium audio signal. The quality is beyond words, you have to hear it to believe it. The difference is incredible when compared to any other microphone. Used in high end specialist hearing aids and medical / military equipment. With high EMI and RFI suppression and excellent noise cancelling providing accurate and clear sound. Reliability is essential when recording sensitive important information or want sound in pure form. It has become standard requirement for many in the sound recording and surveillance industry. 

Hundreds of possibilities can be applied to these microphones with such high-performance. Ideal for new products that require premium audio in miniature / sub-miniature form. Solutions include noise canceling, omni-directional and uni-directional performance. Variables include size, shape, amplification, sensitivity, low noise, and resistance to vibration and mechanical shock.

The variations above include 3 options - Microphone Model, Microphones Connectivity and the Cable Length. Choose microphone model first followed by the choice of 3.5mm Jack plug connector and then cable length. These are for use with most 3.5mm Mono TS / Stereo TRS microphone inputs and 3.5mm TRRS Smartphone headset inputs. Also available is 3.5mm locking jack plug for use with wireless body pack transmitters Sennheiser / Trantec and most other similar transmitters.
