The tinnitus masking feature generates calming background sounds (like white noise or ocean waves) to cover ringing/buzzing in your ears.

To activate it:

  • Double-tap your hearing aid twice quickly to cycle through programs until masking starts.
  • Or long-press (3 seconds) the charging case button while the device is inside.

Core One Pro offers stronger sound output, 160% better noise reduction, and two additional sound modes — including wind noise management and tinnitus masking — all while staying just as discreet.
