QuietOn 4 review

QuietOn 4 is on this list as the alternative for side sleepers who want quiet rather than sound. QuietOn calls it the world's smallest active noise cancelling earbud designed for sleep, and each bud weighs 1.8 g, close to Ozlo's 1.6 g. It deliberately leaves things out: no Bluetooth, no app, no sound masking and no music. The noise cancellation targets low-frequency sounds such as snoring and traffic that passive earplugs struggle with, while Comply foam tips in four sizes from XS to L provide the passive seal. Battery life is up to 28 hours on a charge, the longest of any earbud here, and the charging case doubles as travel storage. QuietOn ships US orders from a US partner, offers a 30-day money-back guarantee and a one-year warranty outside the EU. The official store showed prices in euros when we checked, so we have not listed a US price. Because it plays nothing, it scores lower here than on a pure noise-blocking list.

Who it is for

Side sleepers who want electronic quiet, not sound, and long battery life.
