Harmony is a wearable device aimed at amplifying the user's voice, especially beneficial for aged people with a low voice and where explicit mic-and-speaker arrangements are not needed, but a high voice is required. As it also contains Bluetooth connectivity, it can be used to stream music or as voice input for phones. It's designed to use low power. Thanks to the low-power design, the design can be extended to use solar energy to charge the battery. The OLED display acts as the watch's display.
