If you want a certified, quantified noise-blocking earplug with a fit range that actually reaches extra-small ears, choose CURVD Ear Plugs; if you need a low-pressure, low-profile silicone plug with more tips in the box and a lighter feel for all-night side sleeping, choose Hadrsion Sleep Ear Plugs.
• CURVD's biggest strength: a stated 28dB SNR (EPA NRR 20dB) noise-blocking rating, plus five tip sizes from XXS to L — a rare amount of fit range, especially for smaller ear canals.
• CURVD's biggest trade-off: it's built as an "everyday" plug — sleep, travel, focus, concerts — so it isn't positioned purely as a sleep-specific design, and the purple silicone look is more gear than bedside accessory.
• Hadrsion's biggest strength: a deliberately soft, low-profile shape aimed at side, back and stomach sleepers, with 10 interchangeable tips in S, M and L for a low-pressure fit.
• Hadrsion's biggest trade-off: no noise-reduction rating is stated on the data sheet, and the tips stop at L on the small end of the range — no extra-small option.
• Choose CURVD if you want a measured noise reduction figure and ear tips that go genuinely small.
• Choose Hadrsion if you want the softest-feeling, lightest plug for sleeping in any position and you don't need a decibel claim.
CURVD Ear Plugs are, in my opinion, the more "specified" of these two. The headline number is 28dB SNR, with a certified EPA NRR of 20dB. If you're the kind of buyer who wants a concrete figure to compare against before you commit, that's the entire appeal here. It tells you roughly what the plug is designed to knock down: snoring, traffic hum, noisy neighbors — the everyday noise floor that ruins sleep.
The other half of the story is fit. CURVD ships five pairs of ear tips spanning XXS through L, and the design logic is refreshingly simple: if noise leaks through, size up; if you feel pressure, size down. Very few earplugs reach XXS at all, which is why I'd point anyone with narrow ear canals in this direction first. A plug that doesn't seal doesn't block anything, so that range matters more than any single spec on the sheet. The low-profile body is also explicitly aimed at side sleepers.
Who should skip it? If you want the absolute softest, lowest-pressure feel and you don't care about a decibel rating, Hadrsion's sleep-first shape may suit you better. And if you dislike a saturated plastic color, note CURVD's silicone is purple. That's the whole trade-off.
Hadrsion Sleep Ear Plugs: Who It's For
Hadrsion Sleep Ear Plugs are the opposite philosophy: less numbers, more comfort engineering. The design brief is written entirely around sleeping in any position — side, back or stomach — using a soft, low-profile shape that sits naturally in the ear canal. There's no noise-reduction rating on the data sheet, and I won't invent one. What the sheet does tell you is that these are built to reduce surrounding distractions while still letting some awareness of your surroundings through. That's a meaningful distinction: this is a calmer-environment plug, not a sealed-off-from-the-world plug.
The tip situation is generous in a different way from CURVD. Hadrsion includes 10 interchangeable silicone ear tips in S, M and L. That's more spares, but the range starts at S — there's no extra-small. So if you have very narrow canals, CURVD is the safer bet; if you're a standard S/M/L fit, you'll have plenty of options and backups here.
The rest of the pitch is about weight and pressure. Hadrsion is described as lightweight with a low-pressure wearing experience, reusable and easy to clean. It's compact enough to pocket or drop in a travel case for commuting, office work, studying, reading or meditation. If your problem is a partner's snoring at 2 a.m., the soft, flat profile is the feature you'll notice; if your problem is a leaf blower next door, the missing decibel rating is the gap you'll notice.
Who should skip it? Anyone who needs a quantified noise-blocking figure before buying, anyone with extra-small ear canals, and anyone who wants a hard case and clip included — the sheet lists a compact, lightweight form factor rather than a carry case and accessory.
• Best for measured noise blocking → CURVD Ear Plugs (28dB SNR, EPA NRR 20dB stated).
• Best for very small ear canals → CURVD Ear Plugs (tips from XXS to L, five pairs).
• Best for pure side-sleeping comfort → Hadrsion Sleep Ear Plugs (soft, low-profile shape built for side, back and stomach sleepers).
• Best for low-pressure, lightweight feel → Hadrsion Sleep Ear Plugs (lightweight, low-pressure design).
• Best for spare tips and backups → Hadrsion Sleep Ear Plugs (10 tips in S, M and L).
• Best for keeping awareness of surroundings → Hadrsion Sleep Ear Plugs (reduces distractions while allowing some awareness).
• Best for travel and commuting kit → CURVD Ear Plugs (aluminum case plus a clip for a bag, keys or backpack).
• Best for concerts and loud environments → CURVD Ear Plugs (rated hearing protection rather than a general quieting plug).
• Best for studying, reading and meditation → either, but I'd lean Hadrsion if you want to still hear a doorbell or a name being called.
I'd buy the CURVD Ear Plugs. In my opinion, the combination of a stated 28dB SNR rating, a certified 20dB NRR, and tips running all the way down to XXS is the more useful package for actual noise isolation — and those are the exact things you can't verify or improvise later. The aluminum case and clip seal the deal for travel.
That said, if you're a side sleeper whose only goal is the softest possible plug and you don't need a decibel figure, Hadrsion is the honest alternative. It's lighter, lower-pressure, and comes with more tips. It just can't tell you how much noise it blocks. Check the current price on Amazon for both before you decide.
FAQ
are there earbuds for sleeping
Yes — both products here are in-ear sleep plugs, though they're passive silicone earplugs rather than electronic earbuds. CURVD is a rated, reusable silicone plug for sleep, travel and focus, and Hadrsion is a soft, low-profile silicone plug designed for side, back and stomach sleepers.
what are the best noise cancelling earbuds for sleeping
can you sleep with noise cancelling earbuds
You can sleep in passive earplugs like these, and both are explicitly built for it. CURVD targets side sleepers with a low-profile body and five tip sizes from XXS to L; Hadrsion is designed for side, back and stomach sleeping with a soft, lightweight shape.
is it bad to sleep with noise cancelling earbuds
There's nothing in either data sheet suggesting a problem with sleeping in reusable silicone earplugs — both are described as reusable, comfortable and easy to clean. That said, Hadrsion notes its plugs reduce distractions while still allowing awareness of surrounding sounds, which some sleepers prefer for safety and alarms.
