Hush earplugs are wireless noise-masking earplugs that connect to your smartphone and play soothing sounds, reports The Huffington Post.

Invented by three University of California, San Diego students who are all named Daniel (Daniel “Ewok” Lee, Daniel Synn and Daniel “Chesong” Lee), Hush earplugs hit Kickstarter on Nov. 12 with a goal of $100,000. As of Wednesday, the campaign had raised almost $240,000.
