Noise cancelling technology, which is widely used in headphones, lets users drown out background distractions to hear their music better. But what if you don't want to hear anything at all? Standard earplugs often don't cut it (or bring inconveniences of their own), so the new QuietOn earplugs use active noise cancelling (sans music) to minimize what users can hear.

The QuietOn earplugs aren't the only noise cancelling earplugs available (there's ProSounds X-Pro earplugs, which passively cancel different noise using valves, and Hush earplugs, which combine passive cancellation with white noise or nature scenes). But QuietOn differentiates itself by using active noise cancelling tech similar to what you'd find in some consumer headphones.
