We’ve all been there: noisy airplanes, loud passengers and the struggle to fall asleep and have time pass quickly. Finnish tech startup QuietOn wanted to create an active, noise-cancelling earbud both comfortable and effective. Enter: QuietOn 3.1.

These tiny earbuds are powered by active noise-cancelling technology to improve sleep by reducing low-frequency sounds like talking passengers, traffic noises and rumbling plane engines. Fitting entirely inside the ear, QuietOn 3.1 is the only ANC sleep solution comfortable enough for everyone, from side sleepers (no more bulky headphones that make it awkward to lie down) to seated sleepers.

“While white, pink and brown noise machines are often used by consumers to help them fall asleep at night, studies suggest that adding new noise on top of existing noise to attempt to cancel it out isn’t always the healthiest option,” said Janne Kyllönen, founder, QuietOn. “With the QuietOn 3.1 update, we’re looking forward to providing users with a safer and more effective way to get a better night’s sleep.”

The earbuds come in a sleek and compact carrying case, complete with its own battery. A single charge lasts 28 hours. The moment the earbuds are removed from the case, they activate, beginning in a transparent hearing mode before automatically switching over to active noise-cancelling mode within less than a minute.

QuietOn 3.1 comes with four different-sized ear tips and also features zero electromagnetic field radiation due to it not having any receivers, transmitters or connectivity options. QuietOn 3.1 earbuds are available for $289 and include a charging case and charging cable.
