How this page is funded: we earn a commission if you buy through the links below, at no extra cost to you. As an Amazon Associate we earn from qualifying purchases. It does not change which products we pick or the order they appear in. Full disclosure.
How these picks were made: by comparing published specifications and clearly-credited public reporting. We do not run a laboratory, we have not measured these products, and we do not claim to have slept with them. Here is exactly how we choose.
Short version: the Alpine SleepDeep is the alternative to buy if what you want is a reusable plug shaped to be slept on, and it costs less than either Loop sleep model. Mack’s Pillow Soft silicone putty is the one to buy if the flat profile is what you want, because it is a cover rather than an insert and nothing sits flatter. Mack’s Slim Fit is the budget pick - the cheapest plug here, and higher blocking than any Loop.
Loop makes good plugs, and two of them have pages here already - the Quiet 2 review and the Dream in the reusable roundup. People look for alternatives for two honest reasons: price, and the fact that silicone does not suit every ear. Neither is a criticism of the product.
What Loop is known for
Three things, from the maker’s published specifications (Loop Quiet 2, US store) and (Loop Dream):
- Reuse. Soft silicone you wash and keep for months rather than discard after a few nights.
- Sized tips. Multiple ear-tip sizes in the box - the Dream offers four sizes XS to L plus four Double Tip sizes - which is how Loop gets a seal across very different ears.
- A body meant for a pillow. A low-profile shape that does not get levered inward when you lie on it.
What Loop deliberately does not sell is maximum attenuation. The Quiet 2 is 14 dB NRR and 24 dB SNR - the same plug under the US and European standards (why the two numbers differ) - and the Dream is 21 dB NRR. Cheap foam reaches 31 to 33 dB. If blocking is what you are shopping for, every alternative below beats Loop on paper.
If what you want is a reusable plug
Buy the Alpine SleepDeep. It is the closest match in kind: reusable, sized small, medium and large with a multisize pack to find your fit, and an oval body that follows the ear’s contours so it sits flat under a pillow (manufacturer specifications). The material is the differentiator - it is silicone-free and hypoallergenic, which makes it the plug to try if Loop’s silicone has made your ears itch or ache.
It costs less than either Loop sleep model, and it keeps the thing most people actually bought Loop for: a washable plug in a shape designed for sleeping rather than for a factory floor.
If what you want is the flat profile
Buy Mack’s Pillow Soft. It is moldable latex-free silicone putty at NRR 22 dB, and the important detail is that the maker is explicit it is a cover over the canal entrance rather than an insert (specifications and fitting instructions). Nothing sits flatter against a pillow, because there is nothing protruding to press.
The trade is real: you shape it by hand every night, it attracts hair and lint, and it is not for anyone who wants to pop something in and roll over. But at 22 dB it blocks more than a Quiet 2 and costs a fraction of it. The side-sleeping comparison is on earplugs for side sleepers.
If what you want is comfort at higher blocking
Buy the Flents Protechs Super Sleep. NRR 29 dB in soft foam the listing describes as pressure-reducing, sold specifically for sleeping rather than for work sites, in 50 and 10 pair packs (listing specifications). It is the sensible answer to “I want Loop’s comfort and foam’s blocking” - disposable rather than reusable, but comfortable at a rating Loop does not reach.
If you want the highest blocking in a narrow body instead, Mack’s Slim Fit is NRR 31 dB in a smaller barrel (manufacturer specifications), and it is the cheapest thing on this page.
What no alternative here matches
The tip ecosystem. Loop’s eight tip options on the Dream, and the ability to buy replacements separately, is the thing nothing else in this price range offers - and for an ear that falls between standard sizes, that is the whole product. Alpine gets you three sizes; Loop gets you eight.
Remember too that published NRR assumes ideal insertion, and NIOSH recommends derating it for field use (NIOSH 98-126). A Loop that seals every night can outperform a foam plug rated 10 dB higher that you fit badly. That is the real argument for the tips, and it is why the honest recommendation is to try the cheap alternatives first and buy the Loop if none of them seal. For the full field, see the main earplug roundup and earplugs under $25.

Our top pick · Anyone who has tried foam and silicone and found both painful
1. Alpine SleepDeep
A silicone-free oval plug sold in three sizes, for the case where the problem is not the material but that nothing has ever fit your ear properly.
- Rating:
- Up to 27 dB SNR (manufacturer figure)
- Material:
- Silicone-free, hypoallergenic, with a noise-reducing core
- Fit:
- Small, medium or large, plus a multisize pack to find your size
- Care:
- Washable and reusable; the manufacturer quotes up to six months of use
What it gets right
- The oval shape follows the ear rather than plugging it, which is the design that stops pillow pressure
- Three sizes sold separately, so two differently-shaped ears can be fitted individually
- Silicone-free and hypoallergenic, which matters if silicone has irritated you before
Where it falls short
- More expensive than a bag of foam, and the multisize pack costs more again
- Three sizes is fewer options than the eight tip pieces Loop ships
- Six months of life, not a year, so the running-cost case is weaker than it looks
Skip it if: You are fighting genuinely loud noise. An SNR in the mid-20s is a comfort-first number, not a blocking-first one.

Pick 2 · The flattest possible profile against a pillow
2. Mack's Pillow Soft Silicone Putty Earplugs
Moldable silicone that covers the ear opening instead of going into the canal, so there is nothing inside your ear for the pillow to press on.
- Rating:
- NRR 22 dB (manufacturer figure)
- Material:
- Moldable, latex-free silicone putty
- Fit:
- Molded by hand to your own ear each time
- Reuse:
- Reused until dirty or no longer tacky - Mack's says up to five uses
What it gets right
- Nothing sits inside the canal, which removes the pressure problem rather than softening it
- Molds to an ear shape that no stock tip size matches
- The cheapest entry point here, and stocked in nearly every drugstore
Where it falls short
- Tacky silicone catches hair and can pull at it when you take them out
- Five uses per pair means an ongoing cost if you wear plugs nightly
- Must be worn over the opening, never pushed in - people who insert them anyway are the source of most complaints
Skip it if: You sleep with long hair loose, or you want something you can wash and reuse for months.

Pick 3 · Anyone who has to stay wakeable
3. Flents Protechs Super Sleep Foam Ear Plugs
A sleep-specific foam plug that trades four decibels for a softer, lower-pressure body - and leaves you enough hearing to catch an alarm or a child.
- Rating:
- NRR 29 dB (figure printed on the listing by Flents)
- Material:
- Soft foam; the listing describes it as reducing pressure
- Intended use:
- Sold specifically for sleeping rather than for work sites
- Pack:
- 50 pairs; also sold in a 10-pair pack
What it gets right
- The lowest-pressure retail foam plug that still reaches the high twenties
- Four decibels down from the top is usually the difference between hearing an alarm and not
- Sold in a small pack, so trying it is cheap
Where it falls short
- The most expensive per pair of any plug on this page
- NRR 29 is not enough for loud snoring or a busy road
- Disposable, like all foam
Skip it if: Your problem is a snorer. Start at NRR 33 and work down only if comfort forces you to.

Pick 4 · Small or sensitive ear canals that standard foam hurts
4. Mack's Slim Fit Soft Foam Earplugs
A smaller-diameter version of the standard soft foam plug, which is exactly why it works for people whose ears ache in regular foam by 2am.
- Rating:
- NRR 31 dB (manufacturer figure)
- Material:
- Ultra-soft polyurethane foam with a smooth skin
- Fit:
- Smaller diameter than standard foam plugs
- Reuse:
- A few nights each, then discard
What it gets right
- The most blocking on this page, by a clear margin
- The narrower barrel is the specific fix for canals that standard foam presses on
- Cheap enough per pair that losing one in the sheets is a non-event
Where it falls short
- Foam still has to be rolled and inserted deep, and a deep plug puts more of itself inside the ear you are lying on
- At 31 dB you may sleep through an alarm you need to hear
- Disposable, so there is a permanent running cost and ongoing waste
Skip it if: You have to hear an alarm, a child or a smoke detector. Nothing about a high NRR is a feature on that night.
Questions people actually ask
What is the best alternative to Loop earplugs for sleeping?
The Alpine SleepDeep. It is the closest match in kind - reusable, sized, and shaped with an oval body that sits flat under a pillow - and it is silicone-free, which makes it the one to try if Loop's silicone irritates your ears. It also costs less than either Loop sleep model.
Is there a cheaper alternative to Loop Quiet?
Several, and most of them block more. Mack's Pillow Soft putty is NRR 22 against the Quiet 2's 14 dB NRR and costs a fraction as much; Mack's Slim Fit is NRR 31 and cheaper still. What you give up is reuse and the sized-tip system.
Do Loop earplugs block less than foam?
Yes, by design. The Quiet 2 is 14 dB NRR and the Dream is 21 dB, where cheap disposable foam reaches 31 to 33 dB. Loop is built around comfort, reuse and still being able to hear an alarm rather than around maximum attenuation.
What is like Loop Dream but cheaper?
The Alpine SleepDeep is the nearest thing: reusable, sized, and shaped for side sleeping, at a lower price. It offers three sizes plus a multisize pack rather than the Dream's eight tip options, which is the main thing you give up.
Are Loop earplugs worth the money?
If your ear falls between standard sizes, the tip range is worth paying for - a plug that seals comfortably every night beats a higher-rated plug you fit badly. If standard foam already seals for you, you are paying for convenience rather than performance.
