Founded by three Bose engineers, these are the earplugs of our (literal) dreams. That's because they're not just earplugs: They are fully functioning Bluetooth earbuds with noise-masking technology and biometric sensing. Which means you can stream a podcast or music before bed, and they'll detect when you've fallen asleep—and seamlessly transition to your chosen masking sound to block out the world (or a partner's snoring) for the rest of the night. In the morning, they can wake you up with an alarm if you want, too. We find them extremely comfortable, even when sleeping on our sides. (They ship with four sizes of ear tips so you can find the perfect fit.) And the charging case makes them easy to travel with—which is good, because we've become totally dependent on them.
