Comply™ Story



At Hearing Components, Inc., parent of the Comply™ brand, we develop products with an unrelenting passion for hearing.  We do this with a keen interest in providing you with an awe-inspiring listening experience while preserving your ability to hear and communicate.

Welcome to the story behind the sound of science.  Welcome to our world, where science and passion collide.

Our story begins in 1990 when Robert Oliveira, Ph.D. (Dr. Bob) spun the Comply™ brand of products out of 3M.  A serial inventor and biochemist, Dr. Bob worked at 3M for 18 years developing products ranging from biochemical diagnostics to surgical instruments.  An ear canal expert, he also led a team at 3M who developed the world’s first FDA-approved cochlear implant.  Dr. Bob’s research, presented worldwide, demonstrates that the shape and opening of the ear canal changes as one’s jaw opens and closes.  Ear canal shape also changes with such attributes as an individual’s weight, age, and level of hydration.  This discovery of the ear canal’s dynamic nature led our development of numerous unique and patented memory foam solutions to protect and enhance hearing, including the world’s first memory foam earphone tip. 

Offering superior sound isolation, in-ear retention and soft comfort, Comply™ foam tips are sold globally to top brands and through distributors and retailers.  First used for audiology products, our technology has expanded into consumer electronics, military, law enforcement, industrial communications and hunting.  Today, over 75 earphone brands choose Comply™ tips as part of their earphone solution for the ultimate listening experience. 

In high-noise environments, Comply™ has become the standard for many communication systems used in military and industrial settings.  As a result of Hearing Components' knowledge and expertise, we have been awarded several sizable research grants from the National Institute on Deafness and Other Communication Disorders (NIDCD)

We are a R&D focused company with a specialty in foam formulation… just a stone’s throw from our parent, 3M, in Oakdale, MN. 

You’ll never listen to anything the same again.  We promise.
