What to listen for

  • Centered Focus: In Summed Mono mode, audio should sound perfectly anchored in the center of your forehead.
  • Imbalance Check: If Mono audio pulls toward one ear, this indicates driver volume mismatch or uneven ear-tip insertion.
  • Normalization: Mono mix combines Left + Right with -3 dB gain normalization to maintain consistent acoustic level.
