How It works ?

Your hearing cells aren't gone. They're dormant.

Over time, the tiny hair cells inside your inner ear lose the cellular energy they need to function. They stop firing. They go quiet. But for many people, they are still there — just waiting.

HearAmp™ uses 650nm red light — a specific wavelength shown in photobiomodulation research to penetrate inner ear tissue and stimulate the energy centres inside those dormant cells. When the cells get that energy, they wake up. They start firing again. Your natural hearing improves.

Not amplification. Restoration.

Put them in for 20 minutes every morning. That is all it takes.

Margaret testimonial
★★★★★
Week three. My husband said something from the kitchen and I heard him first time. I sat down and had a proper cry. I use it every morning with my tea now. He says it's like having me back.

David testimonial
★★★★★
I'd stopped suggesting restaurants. Four weeks in and we went back to our favourite Italian. I heard the whole evening. Not fragments — the whole thing. My wife just looked at me across the table and smiled. She knew.

Carol testimonial
★★★★★
I paid £3,200 for private hearing aids that whistled and went in a drawer. HearAmp™ cost me £69. Six weeks later I can hear clearly in a restaurant for the first time in four years. The comparison is almost embarrassing.

Trial Results

What 836 users reported after 90 days

Self-reported outcomes from a 90-day trial. These are the numbers that matter to the people who tried it.

86%
Reported meaningful hearing improvement within 30 days
79%
Reduced TV volume to a comfortable level for the family
83%
Noticed significant reduction in tinnitus symptoms
94%
Said family conversations became enjoyable again

Results are self-reported by trial participants over a 90-day period. Individual outcomes vary depending on the nature and severity of hearing loss. Results are cumulative — improvement builds with consistent daily use.

Clinical Perspective

Why audiologists are taking notice

For decades, the standard model of hearing loss said damaged hair cells are gone permanently. New research is changing that picture — and the most significant shift is the distinction between cells that are dead and cells that are simply dormant.

"In over twenty years of audiology practice, I've seen too many patients leave appointments with nothing more than a resignation letter. The evidence base for photobiomodulation in hearing health is growing — and what distinguishes it is that it works at the level of cellular energy production rather than simply amplifying what remains."

Clinically Developed HearAmp™ by Derythm

Using HearAmp™

Three steps. Twenty minutes. Every morning.

Designed to fit into real British life — not require a new one built around it.

1
Minutes 0–1

Insert HearAmp™ like ordinary earbuds

Sit in your armchair. Make a cup of tea. There is nothing to configure, no app to download, no complicated settings. They fit comfortably and naturally in both ears.

2
Minutes 1–20

The 650nm light reaches your dormant hair cells

The precisely calibrated red light penetrates into your inner ear tissue — exactly where damaged and dormant cells are located. It stimulates the mitochondria inside those cells, restoring their energy production. Session by session, more cells become active.

3
Weeks 2–8

Notice the difference building day by day

Most users notice the first real changes between weeks two and four. Not overnight transformation — but genuine, cumulative improvement. Conversations becoming clearer. The television volume coming down. The world becoming more complete.

Questions & Answers

The questions we'd ask if we were you

My audiologist told me hearing loss is permanent. Are you saying they're wrong? +
Not entirely. Severely damaged or fully destroyed hair cells cannot currently be regenerated. What the growing body of photobiomodulation research shows is that many cells appearing non-functional are dormant rather than dead — they have lost cellular energy but haven't disappeared. Red light at 650nm stimulates the mitochondria inside these cells, restoring their energy production. We are not claiming to regrow tissue. We are working with what is already there.
How is this different from hearing aids? +
Hearing aids are amplifiers. They make everything louder — which includes background noise, feedback, and everything else you didn't want louder. They address none of the underlying reasons your hearing has declined. HearAmp™ works at the cellular level, aiming to restore the functioning of the hair cells themselves. This is not compensation — it is restoration.
Does it help with tinnitus as well as hearing loss? +
Many users report significant tinnitus improvement alongside general hearing improvement. This is consistent with research suggesting tinnitus is often the brain's response to reduced sensory input from damaged hair cells. As natural hearing improves, tinnitus commonly reduces. 83% of our 90-day trial participants reported noticeable tinnitus reduction.
How long before I notice a difference? +
Most users report the first noticeable changes between weeks two and four of consistent daily use. The improvement is cumulative — it builds. Some people notice a difference within the first ten days; others take closer to six weeks. The nature and severity of your hearing loss will affect the timeline. This is why our guarantee covers the full 30-day period.
What if it doesn't work for me? +
You have 30 days from delivery to try HearAmp™ with no financial risk. If you don't notice any meaningful improvement, contact our Support team and we will refund you in full. No complicated return process, no questions designed to make you give up. A complete refund. We are confident enough in this product to back it completely.
Is it safe to use? +
Red light therapy at the wavelengths and intensities used in HearAmp™ has a well-established safety record across numerous medical applications. The 650nm wavelength is widely studied in photobiomodulation research. The device generates no heat in the ear canal and has no known side effects at recommended usage levels. It is drug-free, non-invasive, and does not require a prescription.
