How We Build

Building smart earbuds with an ear-hook design requires coordinated work across audio engineering, embedded systems, and companion software.

Audio engineering

  • Acoustic tuning for everyday in-ear listening
  • Microphone, playback, and voice-capture planning
  • Noise control, call quality, and listening balance

Embedded systems

  • Low-power firmware and device-state behavior
  • Bluetooth connectivity, sensors, and battery coordination
  • Hardware integration across the main device subsystems

Companion software

  • Companion app flows for setup and device controls
  • Listening settings, status surfaces, and everyday interactions
  • Product validation across device and software behavior
