for placing your trust in the ear-measurement technology AR KI TECH. Here are the instructions for the ear measurement. It takes only two steps (2 min) for us to combine two technologies, the AR (augmented reality) and the KI (artificial intelligence), to measure your left and right ear. The AR technology measures distances based on the uploaded photos of your ears. In the second step, the AI technology analyses the uploaded images and, based on algorithms (about 3 million experiences), offers the best individual selection of earplugs – just for you.
