How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want one set of soft silicone tips that can rescue several pairs of earplugs you already own and finally fit the smallest ears, choose CURVD Earplug Replacement Tips; if you need a complete, ready-to-wear corded silicone earplug for sleep and study, choose MUCKLILY Noise Cancelling Silicone.
• CURVD's biggest strength: five pairs across five sizes (XXS, XS, S, M, L) in soft, hypoallergenic silicone, so you can re-tip earplugs you already own instead of replacing them.
• CURVD's biggest trade-off: it's a set of replacement tips, not a finished earplug — you need an existing pair of earplugs or earbuds to put them on.
• MUCKLILY's biggest strength: a single, complete, corded silicone earplug that's ready to use out of the box, with a lanyard cord so you can drape it around your neck between uses.
• MUCKLILY's biggest trade-off: it comes as one reusable unit in one size, so there's no fit ladder to climb if your ears sit at either extreme.
• Who CURVD is for: anyone who already owns earplugs and wants better comfort, a smaller size, or a refresh without buying a whole new pair.
• Who MUCKLILY is for: anyone who wants a simple, self-contained soft silicone earplug for sleep, study, travel and quiet focus.
Think of CURVD as a fit-and-comfort upgrade kit rather than a product you wear on its own. The pack contains five pairs of soft silicone tips spanning XXS, XS, S, M and L, which is unusual breadth — most replacement sets stop at S/M/L and leave small-eared sleepers stuck. If you've ever pushed a medium tip in, felt it pop back out, and given up on earplugs entirely, the XXS and XS options in this set are the whole point.
The material story matters just as much. CURVD uses hypoallergenic silicone with a soft, flexible feel designed for prolonged wear — which is exactly what sleep use demands, since you're asking your ear to tolerate something for six to eight hours. A stiff tip that's fine for a twenty-minute commute becomes unbearable at 3 a.m. The ergonomic, snug-fit shape is aimed at sealing the ear canal properly, and a proper seal is what actually delivers isolation; a loose tip leaks no matter how good the underlying earplug is.
Compatibility is the other reason to buy. CURVD explicitly lists its tips as fitting CURVD Everyday Earplugs, Loop Quiet, Engage and Experience, Jayine, Audree and a range of other earplugs. So if you already own any of those and the stock tips have hardened, gone missing, or never fit, this set lets you keep the earplug and fix the part that's failing. Five pairs also means you can experiment with sizes per ear — plenty of people are a medium on one side and a small on the other — and keep spares in a bag or drawer.
MUCKLILY Noise Cancelling Silicone: Who It's For
MUCKLILY takes the opposite approach: it's one complete, reusable earplug made from lightweight, flexible silicone, finished in black, and designed to be worn as-is. There's no assembly and no compatibility question — you open it, put it in, and get on with your night or your study session.
The cord is the defining feature. MUCKLILY builds in a lanyard cord, and that changes the daily experience in small but real ways. Corded earplugs are easier to find when you wake up, easier to hang around your neck when someone interrupts your focus, and much harder to lose in a bedsheet or a carry-on bag. MUCKLILY specifically frames it for snoring, sleep, travel, work and meditation — scenarios where you're taking the plug in and out repeatedly rather than wearing it once and forgetting it.
Comfort is pitched at long wear: soft material, ergonomic shaping, lightweight construction, described as suitable for extended use without discomfort. The whole thing is compact and portable, which fits the travel and study angle — it disappears into a pocket or a small pouch. Noise isolation is the headline claim, with the silicone body described as providing high-efficiency blocking for concentration and relaxation.
The honest trade-off is fit flexibility. MUCKLILY comes as a single reusable unit in one size, so there's no XXS-to-L ladder to work through. For average ears that's a non-issue. For very small or unusually shaped ear canals, a one-size product is a gamble — and a poor seal means the isolation you bought it for doesn't show up. If you already know you need an extra-small tip, that's a genuine reason to hesitate.
Side-by-Side: Which Should You Choose?
• If you already own earplugs and want them to fit better → CURVD, because the XXS–L range lets you dial in the seal.
• If you want a complete earplug with nothing else to buy → MUCKLILY, a single ready-to-wear corded silicone unit.
• If your ears run small → CURVD, since it's the only one of the two offering XXS and XS.
• If you want spares and size experimentation → CURVD, five pairs versus one reusable unit.
• If you want the simplest possible routine for sleep, study and travel → MUCKLILY, no fitting, no swapping, no assembly.
• If you're replacing worn, hardened or missing tips → CURVD, that's precisely what it's built for.
• If you're buying for someone else and don't know their size → MUCKLILY is the lower-risk gift; CURVD's five sizes are the better gift for someone whose size you do know.
In my opinion, CURVD Earplug Replacement Tips is the smarter buy for most people reading this, because so much of sleep-earplug misery is a fit problem, and five sizes in soft hypoallergenic silicone directly attacks that. If you already own Loop or CURVD earplugs, this is the cheapest way to make them wearable again. I'd pick MUCKLILY instead if you want one self-contained corded earplug and you're confident a single size will seat properly in your ears — the cord alone makes it the more practical choice for study sessions and travel. Check the current price on Amazon for both before deciding, since value depends on what you already own.
how to put on silicone earbuds
Replacement tips like CURVD's slide onto the nozzle of your existing earplug or earbud — you stretch the soft silicone over the stem and ease it until it seats fully. Fit the smallest size that seals without pressure, then try the other ear separately, since the two sides often differ. MUCKLILY is different: it's a complete earplug, so nothing goes on it — you simply insert the silicone body with the cord hanging outside.
what are the best earbuds to sleep in
The honest answer is the ones that seal properly and stay comfortable for hours, which is why fit matters more than branding here. CURVD's five-size range (XXS through L) is built for exactly that kind of tuning, and it works with earplugs from CURVD, Loop Quiet, Engage, Experience, Jayine and Audree. MUCKLILY is a corded silicone earplug designed for sleep and rest, and it's the simpler pick if you don't want to think about sizing at all.
are there earbuds for sleeping
Yes — both of these are aimed at sleep and quiet rest. MUCKLILY is a complete reusable silicone earplug with a lanyard cord, described as comfortable for extended wear and suitable for sleep, travel, work and meditation. CURVD is the replacement-tip route: soft hypoallergenic silicone tips that upgrade sleep earplugs you already own, including XXS for the smallest ears. Neither is an electronic noise-cancelling headphone — the isolation comes from the silicone seal.
Both rely on silicone sealing your ear canal, so isolation quality comes down to fit more than anything else. CURVD gives you five sizes to chase a proper seal, which is a real advantage if stock tips never fit you. MUCKLILY provides one reusable corded unit with silicone construction described as high-efficiency noise blocking. If your ears are average-sized, either can work; if they're very small, CURVD's size range is the safer bet.
