We’ll admit it, products prefaced with “smart” pique our interest. Because usually it means better. Hush earplugs are no exception. These wireless smart earplugs block noise & produce sleep-inducing sounds like pink & white noise, & binaural beats that can be programmed & changed with the Hush app. For proper fit, each pair comes with a variety of soft rubber tips so they sit snug in your ears while you sleep.
