For sleep, comfort beats the highest rating. Slim foam blocks the most when fitted with the roll, pull, insert, hold method; silicone putty or wax pressed over the canal opening suits side sleepers and sensitive ears. Hearing your heartbeat is the normal occlusion effect. Test that you can hear your alarm, keep plugs clean and see a doctor for ear pain or discharge.
The best earplug for sleeping is not the one with the highest number on the box. It is the one that stays in, does not hurt when you lie on your side, and still lets you wake for an alarm. This guide compares the main types, shows you how to fit them properly, and solves the problems people complain about most: side-sleeping pain, plugs falling out, and hearing your own heartbeat.
Do earplugs actually help you sleep?
They can. A Cochrane review of 30 trials involving about 1,600 intensive care patients found some evidence that earplugs, eye masks or both may improve sleep, although the quality of evidence was low. One randomized trial in intensive care found that the benefit was partly offset by discomfort. That research took place in hospitals, not homes, but the lesson carries over: comfort decides whether earplugs work for you.
The main types compared
| Type | Blocking | Comfort for side sleepers | Reusable? | Good for |
|---|---|---|---|---|
| Foam | High, if fitted deeply | Good if slim or small sizes | Short-term only | Snoring partners, traffic |
| Silicone putty (covers the canal opening) | Moderate | Very good; sits flat | A few nights | Sensitive ears, people who dislike deep insertion |
| Wax | Moderate | Good; molds to the ear | A few nights | Small ear canals |
| Flanged or shaped reusable silicone | Low to moderate | Varies; some stick out | Yes, washable | Light noise, people who want reusable |
| Custom molded | Depends on design | Often excellent | Yes | Nightly users who want a precise fit |
All US hearing protectors carry a Noise Reduction Rating (NRR). For sleep, a slightly lower-rated plug that you can wear all night beats a high-rated one you pull out at 2 a.m. Real-world protection is usually well below the label anyway; see our hearing protection guide.
How to fit each type
Foam: roll, pull, insert, hold
- Roll the plug into a thin, tight cylinder with clean, dry fingers.
- Pull the top of your ear up and back with the opposite hand to straighten the canal.
- Insert it well into the canal.
- Hold it for 20 to 30 seconds while it expands.
Most of a well-fitted foam plug sits inside the ear. If a lot sticks out, it will block less and press when you lie on your side.
Silicone putty: over, not in
Warm the putty in your fingers, flatten it and press it over the opening of the ear canal, not into it. It should seal the entrance without being pushed inside.
Wax
Warm and soften it, then shape it over the canal opening in the same way as putty.
Solving the common problems
"They hurt when I sleep on my side." Try slim or small foam, silicone putty or wax, which sit flush with the ear. Hard plastic or bulky shaped plugs tend to press.
"They fall out during the night." Foam usually falls out when it is not inserted deeply enough. Re-check the roll-pull-insert-hold method, or try a smaller size so it can go in further.
"I can hear my heartbeat or my own breathing." This is normal. When the ear canal is sealed, sounds from inside your body travel more clearly, which is known as the occlusion effect. It usually becomes less noticeable within a few nights. A slightly less deep fit, or putty over the canal, can reduce it.
"Will I hear my alarm or a smoke alarm?" Test it. With earplugs in, run your alarm and press the test button on your smoke alarm while lying in bed. If you cannot hear them clearly, use a vibrating alarm, move the alarm closer or choose a lower-blocking plug.
"They don't block my partner's snoring." Snoring has a lot of low-frequency energy. Combine well-fitted foam plugs with a steady background sound, and see how to block a partner's snoring. Very loud snoring with gasping or pauses in breathing is worth a doctor's visit for your partner.
Keep your ears healthy
- Wash your hands before inserting plugs.
- Replace foam plugs often, and wash reusable ones as the maker directs.
- Do not share earplugs.
- Stop and see a doctor for ear pain, discharge, persistent itching, a feeling of blockage or reduced hearing.
- Never dig for a plug or a piece that breaks off inside the canal; get it removed by a clinician.
Earplugs can push earwax deeper for some people. If you use them every night and notice fullness or muffled hearing, have your ears checked. Our guide to sleeping with earplugs every night covers long-term use.
Myths worth dropping
- "A higher NRR is always better for sleep." Comfort and fit matter more.
- "Earplugs cause infections for everyone." Clean hands and fresh plugs reduce the risk; see a doctor if symptoms appear.
- "If I hear my heartbeat, they're faulty." That is the normal occlusion effect.
The short version
Choose comfort first: slim foam for the most blocking, silicone putty or wax for side sleepers and sensitive ears. Fit foam with roll, pull, insert, hold. Test that you can hear your alarm, keep plugs clean and see a doctor for any pain or discharge. For a complete sleep setup, read the quiet bedroom.
Questions people ask
Is it safe to sleep with earplugs every night?
For most people, with clean hands and fresh or washed plugs. See a doctor for pain, discharge, blockage or reduced hearing, and have ears checked if you notice fullness.
What earplugs are best for side sleepers?
Slim or small foam, silicone putty or wax, which sit flush with the ear. Bulky or hard plugs tend to press.
Why do I hear my heartbeat with earplugs in?
Sealing the ear canal makes body sounds travel more clearly, called the occlusion effect. It usually becomes less noticeable within a few nights.
Will I hear my alarm with earplugs?
Test it with plugs in. If not, use a vibrating alarm, move it closer or choose a lower-blocking plug.
