You're not alone
Our founder has hearing loss. But for years, no one knew—not even close friends or colleagues. That’s common. Hearing loss, like mental health, is something we don’t talk about.
Yet according to the World Health Organization, 1 in 5 people globally experience hearing loss, and only 20% use hearing aids.
Why? Because the hearing aid experience has long been frustrating, confusing, and impersonal. About half of those who get a hearing test leave without doing anything—not because they don’t need help, but because they haven’t found something that works.
We built Concha Labs for those people— the ones still searching.

Why hearing is personal—and complex
Hearing loss isn’t just about volume. Two people with identical audiograms can need completely different adjustments to produce different sound profiles.
That’s why our approach focuses on personalizing hearing across the entire sound profile, to help you hear speech clearly even in background noise. We’ve secured 7+ patents to protect our unique methods—and they’re already making a difference.

Understanding the test: Speech in Noise (QuickSIN)
Hearing tests are often done in quiet rooms—but that’s not real life. One of the most important, industry-standard ways to measure real-world performance is the QuickSIN test, or the Quick Speech in Noise test, which measures how well someone can hear speech in background noise.
It’s also a gold-standard clinical benchmark that shows how much clarity a hearing aid really delivers.

Our clinical results
Our technology was evaluated in a clinical trial led by the University of Minnesota and published in Trends in Hearing—a leading, peer-reviewed journal.
The results? Participants using Concha Labs hearing aids achieved an average speech-in-noise score of 1.3, a level typically seen in normal-hearing individuals.
“We found that the self-fitted intervention was also superior to the clinician-fitted intervention for both self-reported benefit and objective speech-in-noise outcomes.”

A personal problem, turned into a mission
“I’ve lived with hearing loss for most of my life, but I never found hearing aids that worked the way I needed them to. They were too loud, too quiet, or just… off. It was frustrating. So I decided to build something that could work for me—something that could personalize hearing across the full sound profile and adapt to each person's unique perception of sound. After years of research and development, we now have a patented approach that’s clinically proven to deliver the kind of hearing I didn’t think was possible.”
