A closer look at the technology inside, and why it works the way it does.

How Kleer Prime Turns Noise Into Clear Sound

Sound reaches a hearing aid the same messy way it reaches an unaided ear. Speech overlaps with traffic, wind, and background chatter, and a person's brain is left to sort out which parts matter. Kleer Prime processes that raw sound in real time, separating speech from noise before it ever reaches the ear canal, using the same 16-channel processing described below. Tap the icon above to hear an unprocessed recording, then tap again to hear the same recording after Kleer Prime's processing. This is not a matter of volume. It is a matter of clarity.

Smarter, Not Louder.

Hearing loss rarely affects every frequency the same way. A person can hear low tones almost normally while missing high tones entirely, a pattern shown in the chart below. Kleer Prime's 16-channel processing measures each of those frequency bands on its own and lifts only what needs lifting, rather than one blanket volume increase across the board. Fine adjustments can be made anytime through the free companion app, without a clinic visit.

Kleer Prime: precision by frequency

NORMAL HEARING 0 20 40 60 80 100 Volume (dB) 250 500 1000 2000 4000 8000 Frequency (Hz) Normal Mild Moderate Mod. Severe Severe Profound

Each frequency band is measured and lifted on its own, so every tone lands back at a normal, comfortable level.

The Problem With One Volume for Everything

Many basic sound amplifiers apply a single volume boost across every frequency at once. It is simpler to build, but it creates two problems together. Tones that were already comfortable get pushed too loud, while the high tones a person actually needed help with still do not get lifted far enough to become clear. The chart below shows this tradeoff across a typical hearing profile. Kleer Prime's per-channel approach exists specifically to avoid it.

Basic amplifier: one setting for everything

NORMAL HEARING 0 20 40 60 80 100 Volume (dB) 250 500 1000 2000 4000 8000 Frequency (Hz) Normal Mild Moderate Mod. Severe Severe Profound too loud too loud still unclear still unclear still unclear

One flat volume boost overwhelms tones that were already fine, and still leaves the missing ones out of reach.

Noise Reduction That Actually Protects You

Sudden loud sounds, a dropped pan, a slamming door, a passing truck, are not just startling. Repeated exposure to sudden loud noise can cause real harm to hearing that has already been strained. Kleer Prime listens continuously and generates an opposite signal the instant it detects a spike in volume, canceling it out before it reaches the ear automatically, with nothing to adjust by hand. The chart below shows that cancellation in action.

Sudden noise cancellation

Sudden loud sound + Instant anti-noise signal = What reaches the ear

A sudden loud sound is met with an equal, opposite signal before it ever reaches the ear.

Stopping Feedback Before It Ever Starts

The high pitched whistle known as feedback is one of the most common complaints people have about hearing aids, and one of the fastest ways someone stops wearing one. It happens when sound leaking from the ear gets picked up again and re-amplified in a loop. Kleer Prime detects the earliest stage of that loop, often before it is audible, and cancels it automatically. Kleer Prime also includes a dedicated tinnitus relief mode, offering a gentle masking sound for anyone who needs it.

Feedback (whistle) cancellation

Feedback building up + Canceling signal = No whistling

The moment feedback starts to build, an opposite signal cancels it before it turns into a whistle.
