Speech-range amplification
Targets the frequency range where speech clarity is lost first.

BUILT ON PROVEN HEARING SCIENCE
Hearo One targets the 350–5000 Hz speech range — where human speech lives, and where clarity fades first. It’s the same range prioritized in clinical hearing research.

SOUNDS FAMILIAR?
Most Hearo One customers say the same thing: they can hear, but voices feel muffled or tiring to follow — especially in conversations or busy rooms.
You hear people talking, but it sounds soft, blurred, or hard to pick apart.
You’re the only one who wants the TV louder — and still miss parts of shows.
You can hear the noise in busy places, but not the actual words people say.
Hearo One is tuned for mild-to-moderate hearing loss — the most common type as we age.
Effortless setup
A physical volume dial, universal fit, and a LED charging case. You don’t need to be tech-savvy to hear clearly.
QUESTIONS?
If you’re not sure whether Hearo One is right for you, these are the key details our customers care about most.
Hearo One is designed for mild-to-moderate hearing loss — the most common type as we age. It’s ideal if you hear sounds, but voices feel muffled or unclear, especially in conversation or when the TV is on.
Most people who benefit from Hearo One say the same thing: “I hear sounds fine… I just can’t clearly understand the words.”
If you have severe or sudden hearing loss, pain, or dizziness, you should see an audiologist or doctor in person before using any hearing device.
Yes — this is the exact type of hearing difficulty Hearo One is designed for. Many people can hear sounds perfectly well but struggle to follow speech, especially in conversations or noisy rooms.
Hearo One amplifies the specific speech frequencies that help separate voices from background noise — so words become easier to follow without making everything else uncomfortably loud.
Hearo One uses digital speech processing, feedback suppression, and frequency-targeted amplification in the 350–5000 Hz speech range.
That means it’s built to clarify voices — not just turn everything up the way basic sound amplifiers do.
No phone, no app, no pairing required. Hearo One is controlled with a simple physical dial on each device. Turn it on, set your volume, and you’re ready.
You get 30+ hours of use per charge with the included charging case. Just place the devices in the case when you’re not wearing them and plug the case into any USB power source.
Most customers charge the case every few days, similar to wireless earbuds. The case shows a clear charging indicator so you always know when the earbuds are topped up.
You can try Hearo One at home for 90 days. If it doesn’t help, simply contact us for a return — no clinic visits, no pressure, no questions about why.
Most people notice improvement within the first few days. We recommend wearing it regularly for the first 2–3 weeks so your ears and brain can adjust to hearing clearly again.
