The earphones you’re wearing to drown out the noise of the ride home, take conference calls and pretend like you’re not interested in what’s going on around you don’t fit all that well. It doesn’t matter which pair of the included fifteen silicone plug sizes you installed on the part that generates the sound; if they’re not custom made to fit your exact ear, they’re not as good as they could be. There are brands that already do this, but the process is time consuming and costly. Not with Normal. Using the iOS or Android app, you take pictures of your left and right ear (like other parts of the anatomy, they’re not identical), select the color you want your buds and send everything to Normal. Once they have the designs of your earholes, they’ll 3D print a pair of buds designed just for you.
