The best earplugs for sleeping in the UK are not the ones with the biggest number on the packet. They are the ones you can wear all night, on your side, without noticing them, and that you will actually put in every evening. That usually means a compromise between three things: how much noise they block, how comfortable they are on a pillow, and how easy they are to keep clean.
As a rule of thumb, foam plugs block the most noise and cost the least, but they are bulky for side sleepers and need replacing often. Reusable silicone plugs sit flatter and can be washed, at the cost of a little less reduction. Wax or silicone putty sits over the entrance of the ear rather than inside it, which some people find the only tolerable option.
Below is what each type does, what to check before buying, how to use earplugs safely, and then a comparison of the main types with examples. If you want the quick, table-only version, see which earplug type suits you.
What earplugs can do, and what they cannot
Earplugs work by physically blocking the ear canal so less sound reaches the eardrum. They are most useful against noise that is steady and predictable, such as traffic, a fan, a boiler or a partner's rhythmic snoring, and against sudden sounds that would otherwise jolt you awake, such as a door or a neighbour's television.
They are not a wall. Low-frequency sound, the kind that comes through floors and walls, is reduced less than higher-pitched sound, so a bass-heavy party next door will still be felt. Sound also reaches the inner ear through the bones of the skull, so no plug gives silence. What a good plug does is drop the noise enough that your brain stops treating it as a signal worth waking for. If you wake at every creak, why light sleepers wake so easily explains what is going on and why earplugs help some people more than others.
There is a psychological cost too. Some people find the sound of their own breathing and heartbeat, which plugs make more noticeable, harder to ignore than the traffic was. That tends to fade over a week or two, but not for everyone.
In short: Earplugs turn down the volume of the world enough that ordinary noises stop waking you. They do not create silence, and they only work if you can bear to wear them.
The main types
Foam
Slow-recovery foam plugs are rolled into a thin cylinder, inserted into the canal and left to expand. Done properly, they give the greatest reduction of the common types, which is why they are the default for heavy sleepers in noisy flats. The downsides are real: they stick out of the ear enough to press when you lie on your side, they are single- or few-use, and the running cost adds up. Softer, lower-pressure foams are marketed specifically for sleep and are gentler than the industrial kind.
Reusable silicone
Pre-moulded silicone plugs, often with a round or flanged shape and a choice of tip sizes, are designed to sit low in the ear so the pillow does not push them in. They can be washed and used for months. They generally block a little less than a well-inserted foam plug, which for many people is a fair trade for comfort and cleanliness. Getting the tip size right is essential, so a box with several sizes is worth having.
Mouldable wax or silicone putty
A small ball of soft material is warmed in the fingers and pressed over the opening of the ear canal, not into it. Because nothing goes inside, many side sleepers find them the most comfortable option, and they seal well when applied carefully. They are short-life, they pick up hair and lint, and they are less suited to very loud environments. Wax versions are the traditional form; silicone putty behaves similarly.
Custom-moulded plugs
An audiologist takes an impression of your ear and makes a plug to match. These are the most comfortable long-term option and last years, but they cost far more upfront and are not in our product register. Worth considering if you wear plugs every night and nothing off the shelf fits.
What to look for
Noise reduction, in plain English
UK and EU packets carry an SNR figure (Single Number Rating), the number of decibels the plug reduces sound by under laboratory conditions. Higher is more, but the figure assumes a perfect fit by a trained wearer. Most people get less than the rated reduction, and a plug that is easy to insert well will beat a higher-rated one that you never get in properly. For sleep you rarely need the maximum; you need enough to take the edge off, applied consistently.
Fit and size
Ear canals vary a lot. If a plug hurts after an hour, falls out or leaves you with an ache in the morning, it is the wrong size or shape, not something to push through. Foam comes in different diameters, silicone in several tip sizes, and putty suits ears that reject anything in the canal. Expect to try more than one type.
Side-sleeper comfort
This is the deciding factor for many people. Anything that protrudes gets pushed into the ear by the pillow. Low-profile silicone plugs and putty were designed with this in mind. If you sleep on your side and use foam, choose the softest foam you can find and trim nothing (cut foam loses its shape).
Hygiene and lifespan
A plug that goes into the ear canal every night needs to be clean. Foam is disposable and should be binned once it is grubby or no longer expands, usually after a few nights. Silicone should be washed with warm soapy water and dried fully. Putty is used a handful of times and then thrown away. Never share plugs.
Getting a foam plug in properly
Most complaints that foam plugs do not work come down to insertion. Roll the plug between finger and thumb into a thin, smooth cylinder with no creases. Reach over the top of your head with the opposite hand and pull the top of your ear up and back, which straightens the canal. Slide the plug in until about a third remains outside, then hold it in place for twenty seconds while it expands. Your own voice should sound deep and muffled. If it does not, take the plug out, let it recover for a minute and try again. A plug you can push in without rolling is too small for your ear.
How long each type lasts
Foam plugs lose their spring after a few nights and should be binned once they no longer expand fully or look discoloured. Silicone plugs last months if washed, but the tips soften and split eventually; replace them when the seal starts to feel loose. Putty is good for a handful of nights before it picks up too much lint to seal cleanly. Keeping a spare pair of whichever type you use, on the bedside table, avoids a bad night when one goes missing at midnight.
Safety: alarms, wax and infections
Three things to be aware of.
First, alarms. Most people can still hear a loud bedside alarm through earplugs, but you should check this yourself before relying on it, and think about how you would hear a smoke alarm. A vibrating alarm, a lamp on a timer or a phone under the pillow are useful back-ups.
Second, earwax. Pushing a plug in can compact wax deeper into the canal. The NHS advises against poking anything into the ear to remove wax; if you get muffled hearing or a blocked feeling, a pharmacist can advise on softening drops.
Third, infection. Warm, damp, dirty plugs are a route for bacteria. Clean plugs, replaced regularly, inserted gently, keep this risk low. If you develop pain, discharge or itching, stop and see a pharmacist or GP. For a fuller look at nightly use, read is it OK to sleep with earplugs every night.
Who they suit and who should skip them
Earplugs are a good fit if:
- You live with traffic, a busy street, early bin lorries or thin walls.
- Your partner snores and you have tried the free fixes first.
- You wake at small sounds and then struggle to get back to sleep.
- You travel or stay in unfamiliar rooms.
They may not suit you if:
- You have a current ear infection, a perforated eardrum, grommets or recurring wax problems (ask a pharmacist or GP first).
- You need to hear a child, a monitor or a dependent relative in the night.
- The noise is low-frequency bass or vibration, where sound masking or moving rooms may work better.
- You find the sound of your own body in a blocked ear more disturbing than the noise outside.
If you cannot bear anything in your ears, steady sound from a white noise machine is the other main route. Our guide to earplugs vs white noise helps you decide, and many people find the combination of a softer plug and a steady sound works better than either alone.

Soft foam earplugs
Example: Mack's Ultra Soft Foam Earplugs
Foam plugs are compressed, inserted and allowed to expand. Mack's Ultra Soft are marketed as a low-pressure foam intended for sleeping and are sold in multi-packs. Foam plugs are single- or few-use and should be replaced regularly.
- Best for
- Maximum noise reduction at low cost
- Key feature
- Slow-recovery foam that expands to seal the ear canal
- Why it may help
- For steady noise such as traffic or a partner's snoring, a well-fitted foam plug usually gives the greatest reduction of the common types.
- Worth knowing
- Can feel bulky for side sleepers; disposable, so the cost adds up; check the SNR rating on the pack.
Reusable silicone earplugs for sleep
Example: Loop Quiet
Loop Quiet earplugs are marketed as reusable silicone plugs with a round, low-profile shape and several ear-tip sizes in the box. Manufacturer information describes them as intended for sleep, focus and noise sensitivity.
- Best for
- Side sleepers and people who want a washable, reusable option
- Key feature
- Low-profile, flexible silicone with interchangeable tip sizes
- Why it may help
- They sit flatter than foam, so they are less likely to press into the ear on a pillow, and they can be washed rather than thrown away.
- Worth knowing
- Generally a little less noise reduction than a well-inserted foam plug; fit depends on choosing the right tip size.
Mouldable wax or silicone putty earplugs
Example: Quies natural wax earplugs; Mack's Pillow Soft silicone
Putty-style plugs are pressed over the ear opening rather than inserted into the canal. Wax versions (such as Quies) and silicone versions (such as Mack's Pillow Soft) are both marketed for sleep and swimming.
- Best for
- People who find in-canal plugs uncomfortable
- Key feature
- Soft putty that moulds over the entrance to the ear canal
- Why it may help
- Because nothing goes inside the canal, many people find them the most comfortable option for side sleeping, and they seal well when applied properly.
- Worth knowing
- Single-use or short-life; can pick up hair and lint; less suited to very loud environments.
Free fixes to try first (or as well)
Earplugs are the cheap, fast answer, but the noise itself is often reducible. Move the bed away from the shared wall. Close the trickle vents and heavy curtains, which absorb more sound than you would expect. Put a draught excluder along the bedroom door. Ask the neighbour, politely and once, about the television. The full room-by-room list is in how to block out noise at night.
If the noise is a partner, the answer is rarely just plugs. Positioning, timing who falls asleep first, and, for loud snoring with pauses, a gentle push towards their GP all matter. See how to sleep with a snoring partner.
Where to go next
Start with the type that matches your sleeping position: putty or low-profile silicone for side sleepers, soft foam for back sleepers in loud places. Give each a week, keep them clean, and check you can hear your alarm. If noise is still winning, pair them with steady sound, and browse the rest of the sleep products guides for the machine and headphone options.
Frequently asked questions
Will I hear my alarm or a smoke alarm with earplugs in?
Usually a loud alarm close to the bed comes through, especially with silicone or wax plugs, but you should test this at home rather than assume it. A vibrating alarm, a bedside lamp on a timer or a phone under the pillow are sensible back-ups. If you live alone, keep the smoke alarm test in mind too.
What does SNR mean on an earplug packet?
SNR stands for Single Number Rating, the European measure of how much sound a hearing protector reduces in decibels under test conditions. A higher number means more reduction on paper. Real-world results depend heavily on fit, so a well-inserted lower-rated plug can outperform a poorly inserted higher-rated one.
Can earplugs cause ear infections or wax build-up?
Reusing dirty plugs or pushing wax deeper with in-canal plugs can contribute to both. Wash reusable plugs, replace foam regularly, insert gently and give your ears a break when you can. If you get pain, discharge or muffled hearing that does not clear, see a pharmacist or GP.
Are earplugs or white noise better for a snoring partner?
It depends on the snore. Steady, rhythmic snoring is often masked well by white noise, while loud, irregular snoring usually needs a physical barrier, and many people use both. Our comparison of earplugs and white noise goes through the trade-offs.
