Easy to Use – Just Insert and Sleep
QuietOn 4 is built for effortless sleep. There’s no Bluetooth, no pairing, no app, and no sound masking. Just take the earbuds out of the charging case, insert them into your ears, and they automatically activate Active Noise Cancelling (ANC) mode in 15 seconds. No buttons, no setup. Just pure functionality focused on helping you sleep better.

How Active Noise Cancelling Works
Active Noise Cancelling (ANC) technology uses tiny microphones to pick up the sounds around you and creates opposite sound waves to reduce them. It reacts to all ambient noise the microphones detect, including low‑frequency sounds like snoring or traffic. ANC noticeably lowers these sounds, but it won’t create total silence and no device can.
For the best possible performance, it’s essential that the earbud sits securely and properly in the ear, as a good seal greatly improves both passive and active noise reduction.

Oval Design for a Natural, Comfortable Ear Fit
QuietOn 4 sleep buds use a unique oval‑shaped design that follows the natural contours of the ear for a secure, pressure‑free fit. The ergonomic shape sits comfortably inside the ear without sticking out, making them ideal for side sleepers and anyone needing all‑night comfort. Soft foam tips in four sizes ensure a snug acoustic seal that enhances noise reduction for deeper, more peaceful sleep.
