Inspired by “grains of rice”, the ergonomic invisible-in-the-canal (IIC) hearing aids for users with mild-moderate hearing loss boast compact size and light weight, providing an invisible, comfortable hearing solution. Each hearing aid with a different color (red/blue) is soft, skin-friendly, and easy to distinguish. The supporting APP enables convenient control of the hearing aids via cell phones. The advanced digital chip ensures an ideal hearing experience even in noisy environments.
