Finding the right earphones is tricky business. Your options are basically limitless and everybody has their own favorite brand or shape. The only problem is, where half the world might love a particular kind the other half could hate it. Startup Revols says it's because our ear shape is just as unique as our fingerprints. With this in mind, the company has developed a Kickstarter campaign for its wireless earphones that use gel-filled tips to mold specifically to your ear. All you have to do is place them in, click a button on the company's companion app and let the tips work their magic. Once set, they'll harden to keep their shape. The seemingly simple design and execution has seen the company already reach its crowdfunding goal of $100,000, with 59 days to go.
