Tibbetts Microphones

Sierra Peaks Tibbetts is the only remaining American manufacturer of sub-miniature microphones.  Our units are the industry leader in size and fidelity; you simply can’t find a smaller, more sensitive microphone that is made in America.  Unlike mass producers of inexpensive foreign microphones, we work directly with our customers and partners to custom build microphones to meet the most exacting specifications, in production runs from the hundreds to the tens of thousands.  These devices are commonly used singly or in pairs in hearing devices, communications headsets and audio monitoring applications.

Below you’ll find our standard microphone offerings.  If you’re looking for something a little different or unique, let us know.  We will craft build a unique device to meet your specifications.

151 Series

mic-151

An extremely small package size combined with high sensitivity makes the 151 Series highly versatile for even the most demanding CIC applications.

  • Miniature size – 0.10″ (2.54mm) diameter
  • EMI protection – reduces electromagetic interference
  • Extremely low noise – patented JFET amplifier provides lowest microphone inherent noise specification in the industry
  • Low current drain – circuit design maximizes battery life
  • Optional pre-soldered leads available
