IntriCon hears its future calling, and that future is in precision microminiature components and molded plastic parts, such as volume controls and switches, primarily for use in hearing aids. IntriCon's components are also used in professional audio equipment, such as headsets and microphones, and in biotelemetry devices for such uses as diagnostic monitoring and drug delivery. The company has concentrated it product portfolio on what it terms "body-worn devices" through a series of acquisitions and divestitures, including the 2010 sale of its RTI Electronics business line to Shackleton Equity Partners. About 70% of IntriCon's sales come from the US.
