We are transforming how custom-fit ear devices are made (e.g. hearing aids, noise protection, earphones). Standard-fit ear devices lead to poor fit, which in turn leads to a number of issues (e.g. pain, hearing loss). Hearables 3D addresses this by making custom-fit ear devices more accessible. We do this through our smartphone scanning and automated design technologies, both of which are game changing for ear-device OEMs. Our central mission is to combat the negative impacts of poor device fit, especially pain and hearing loss. Our vision is to make custom-fit devices the new norm by bringing them into the hands of 1 billion humans.
