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.

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.
