  • [Using DearBuds with App]

    Connect with the DearBuds Connect app. (See 3. [Connecting with the DearBuds Connect App] for how to connect)

    After placing DearBuds in your ear and entering the main screen, the temperature/humidity in your ear is measured in real time and displayed on the screen.

    After checking the temperature/humidity in your ears, you can select your favorite mode from the 6 modes (3 smart modes, 3 manual modes) and wait for the dehumidification to finish.

    Once the dehumidification is finished, you will see the maximum and minimum humidity on the screen with an pop-up message.


  • What is a comfort zone? - Taking into account your surroundings, weather information, etc., we automatically calculate the humidity zone where your ears feel most comfortable in the place you are currently located and display it on the screen.
  • Humidity is too high! - After measuring your surroundings, weather information, and the condition of your ears, we set a zone of extremely high humidity and display a notification when your ear humidity level is above that level. If your ear humidity level is above that level, App will notify you.
