QuietOn 4 Review: Earbuds That Cancel Snoring Noise

If you’ve ever been woken by a sound you couldn’t name, chances are it lived below the range of normal earplugs. Low-frequency noise is sneaky, and snoring is its loudest roommate.

This guide explains how the QuietOn 4 goes after that noise and whether the claims hold up. Some links here are affiliate links, so we may earn a commission at no extra cost to you.

How Active Noise Cancelling Works

A tiny microphone listens to the sound reaching your ear. The electronics then play a matching counter-signal that cancels the low-frequency part of it.

Foam alone can’t do that. QuietOn notes that foam plugs reduce higher-frequency noise but let low-frequency sound, like snoring, pass through.

The QuietOn 4 pairs the electronics with a foam tip. The seal does the high end and the cancelling does the low end.

What the Research Says

Snoring is airway vibration, according to the Mayo Clinic. That’s why it lands in the low range that foam misses.

A two-month couples trial of custom-moulded earplugs found better snoring-impact scores for snorers and partners alike. The authors called plugs an effective short-term fix for some couples.

A 2026 sleep-lab study concluded earplugs were efficacious at reducing the effects of intermittent environmental noise on sleep, in contrast to pink noise. Neither study tested QuietOn, so read them as support, not proof.

QuietOn 4 at a Glance

• Claims: up to 30 dB low-frequency cancelling, up to 90% less snoring noise with the foam tip (maker figures).
• Battery: up to 28 hours per charge in Tom’s Guide testing.
• Charging: case recharges over USB-C in about three hours; the earbuds take about two.
• Tips: Comply memory foam in XS, S, M and L.
• Weight: about 1.8 grams per earbud.
• Features: no Bluetooth, no app, no playback.

The specs come from Tom’s Guide and Basic Tutorials, plus QuietOn’s own materials.

Getting the Fit Right

Roll the foam thin, insert it quickly, and hold it for a few seconds while it expands. A poor seal weakens the cancelling, so most problems start here.

The earbuds begin cancelling after you remove them from the case. QuietOn’s FAQ says to allow about 20 seconds, and Tom’s Guide reports about 15 seconds to get them in.

Side sleepers should test with their own pillow, since Basic Tutorials found a very soft down pillow can press on the buds. Pair that habit with the advice in our guide to which sleep positions reduce snoring.

Who Gets the Most From It

Partners of snorers are the obvious fit, since snoring sits right in the low range. Light sleepers in noisy buildings come next, because fans, traffic and bass through walls land in the same range.

People who sleep on their backs or stomachs can use it too, but side sleepers are the design target. Tom’s Guide describes the soft design as comfortable for side sleeping.

It’s a poor fit for anyone who needs to hear a baby monitor or a doorbell at night. Active cancelling lowers the rumble, but it also dampens the sounds you might need to catch.

Price, Returns and Warranty

Tom’s Guide lists a $299 MSRP, and Basic Tutorials lists 259 euros in Europe. QuietOn advertises 30-day returns and a one-year warranty.

When Earbuds Are Not Enough

Earbuds protect the listener. They do nothing for the person making the noise.

Loud snoring with gasping or breathing pauses deserves a medical look, so read our list of early signs of sleep apnea. For other tools, compare our picks in best anti-snoring devices and best earplugs for snoring.

Quick Answers

Does it work for light sleepers who don’t live with a snorer?

It targets low-frequency noise like fans, traffic rumble and bass through walls. Sharp sounds and voices are softened, not erased.

Can I hear a smoke alarm or phone alarm?

Usually, yes. Higher-pitched sounds pass through, but set your alarm volume a little louder.

Did we test it?

Not the QuietOn 4. We reviewed the first-generation QuietOn Sleep before, and the details here come from the maker and independent testers.
