Normal

Seems like the earbuds that come with smartphones and MP3 players never fit: That’s why we’re excited about this Chelsea store. Customers can get fitted (via the Normal smartphone app) for a pair of stylish-yet-high-tech custom-made earphones ($199). 3-D printers produce the buds on-site, so you can wait around at the store’s coffee bar, or have the Normals shipped to you free of charge.
