Our Story

Microsonic Inc. was founded in 1964 by Miklos Major and has since grown into a global leader in manufacturing high-quality custom earmolds. Today, we are a women-owned and operated family business led by Monika Major, a second generation earmold expert and entrepreneur.

Using the highest quality materials available, Microsonic’s skilled craftsmen give each earmold individual attention and create handmade products with absolute precision and care.

Microsonic also utilizes an end-to-end digital workflow, enabling audiologists to uploaded 3D ear scans via our online ordering system directly to our 3D Print Lab. Our experienced and creative designers designers produce earmolds for patients of all ages and even for those with complex fit needs. 

At Microsonic, we are committed to reviewing emerging trends and adopting the latest technologies that best serve our customers. We support the global hearing health industry through our ISO 9001 and 13485 Certified Facilities in the USA and Europe, which combine old-world craftsmanship with the latest technologies in 3D printing. Microsonic also offers the industry’s longest “proper fit” warranty of six months, and all Microsonic earmolds are registered with the FDA.

In addition to our dedication to quality, Microsonic is continually researching, testing and developing new ideas and materials. Some of our innovations include the tragus earmold, stethoscope adapter mold, advanced design free field mold, the use of a silicone canal in conjunction with hard materials, and the tube lock. We hold a number of patents, including the exclusive Tube Lock Plus™, the popular Microsonic Universal Syringe, plus a design patent on our unique SOLO container for individual portions of silicone impression materials. Microsonic has also introduced a number of established European materials and methods to the U.S. market.

Style is a core feature of Microsonic products. Our custom earmold department is staffed with art school graduates and creatives who produce the widest selection of colors and styles available today. Logos, swirls, glitters … we have it all. We can even add fun logos or shapes to most earmolds!  View our Custom Earmold Gallery here.
