Any music lover knows how difficult it is to find earbuds that actually fit inside your ears. A pair of Normals costs $199 (which includes tax and shipping), but the fitting is free: You simply download a free app from the Google Play or Apple app store, and use it to take a few photos of your ears. Pre-ordered Normals wills ship on August 9, but after that, the company says US customers will receive their earbuds within 48 hours of submitting their orders via the app.
