How it works

Find what hurts. Then quiet it.

Haven pairs a wearable DSP device with a guided app. You tell it which sounds bother you — it softens exactly those frequencies, nothing else.

Hearing test

A guided test plays tones that rise slowly from quiet, with a large always-reachable stop button and a hard-coded 85 dB ceiling the app can never exceed. Find your sensitive frequencies safely.

Tune

Choose how many decibels a frequency band is reduced by — from a gentle dip to fully removed — instead of an all-or-nothing notch filter. Up to five bands at once.

Home

One glance answers the only question that matters: protected, or paused. A breathing amber light on the home screen — nothing to configure to check.

Where Haven is right now

Haven is in development and not available yet. Here is an honest snapshot of what exists, what's being checked, and what comes next.

Built & tested in software

The app (hearing test, Tune, Home, pitch matching) and the firmware are written and covered by automated tests. Everything so far has run in simulation and previews — not yet on a physical device.

Dev board: ready to build

The first hardware board is fully laid out and has passed its design-rule checks. We're finishing final pre-order checks (component placement, supply rails, sourcing) before ordering the first small batch of prototype boards.

Next: first real sound

When boards arrive: power-up, Bluetooth, then the audio chip, then hearing your own voice through the device. After that, measuring real output levels so the app's numbers mean real decibels.

Open source

Built in the open, on OpenEarable

Haven's hardware and firmware build on OpenEarable, an open-source ear-worn sensing platform. Everything Haven-specific — app, firmware, hardware, and the early prototypes that got us here — is public.
