Hi there, thank you for sharing your experience. We recommend checking out the user manual for detailed instructions on testing volume settings and proper insertion. Feel free to contact us if you need further assistance!
Each press of the button (press and release) adjusts the volume by one level, with a total of 9 volume levels. Three beeps indicate the maximum volume is reached, and three beeps also indicate the minimum volume when the button is pressed again. Please read the instruction manual.
For detailed instructions on how to wear the device, please refer to pages 21-22 of the instruction manual.
