• CURVD Ear Plugs – biggest strength: Five tip sizes from XXS to L, which is unusually generous for small or awkward ear canals, plus an aluminum case with a satin nickel clip so the plugs travel with you instead of rolling around loose.
• CURVD Ear Plugs – biggest trade-off: The noise reduction rating is lower. It is listed at 28dB SNR with an EPA NRR of 20dB, so if you are chasing the loudest possible block, this is not the louder of the two.
• Tphalen 32dB – biggest strength: A 32dB SNR rating, the higher number here, in a low-profile silicone body that twists flush into the ear.
• Tphalen 32dB – biggest trade-off: Four tip sizes (XS to L) versus CURVD's five, and no case or clip is mentioned in the package contents — just the plugs and spare tips.
• Who CURVD is for: Side sleepers, people with smaller ear canals, and anyone who wants a tidy case that clips to a bag or keys.
• Who Tphalen is for: Buyers who prioritize the strongest stated noise reduction and want a full set of replacement tips in one simple kit.
CURVD's Everyday earplug is built around fit as the whole pitch. The listing carries five pairs of ear tips spanning XXS through L, and the instructions are refreshingly blunt: noise leaking through means size up, pressure building up means size down. That is a real advantage for anyone who has given up on earplugs because "one size" never quite worked. Smaller ear canals, in particular, get an option here that most silicone plugs simply do not offer.
The design is deliberately low-profile, which matters most at night. Side sleepers press an earplug into a pillow for hours, and a plug that protrudes gets nudged loose or digs in. CURVD's shape is meant to contour into the ear so it stays put. The material is soft, reusable silicone, hypoallergenic, and there is no foam to replace weekly — you wash them and keep going.
Buy CURVD if you sleep on your side, have struggled to find tips small enough, or want a case-and-clip system that keeps everything together. Skip it if maximum noise reduction is your single deciding factor.
Tphalen 32dB: Who It's For
Tphalen leads with a number: 32dB SNR. That is the headline spec, and it is the higher rating of the two plugs here. For loud, persistent, harmful-sounding environments — snoring right next to you, a noisy commute, an open-plan office — that extra reduction is the reason to pick this one. The plugs are flexible silicone designed as hearing protection, and the stated goal is a private quiet space you can create on demand.
The fit system is simpler than CURVD's. Four sizes, XS through L, with medium tips pre-installed so the plugs work straight out of the package. Insertion is a twist-to-lock motion, and the low-profile body is meant to sit flush inside the ear without protruding — the same overnight-friendly idea as CURVD. Tphalen also calls out skin-friendly, pliable silicone that stays pain-free through side sleeping, and the plugs are washable for repeated long-term daily use.
What you give up is the extras. The package is one pair of earplugs plus four pairs of replacement tips. No case, no clip. And the tip range stops at L on the small end of the scale — there is no XXS, so the very smallest ear canals get one less option.
Buy Tphalen if the 32dB figure is what you are after and you want a straightforward kit with a spare in every size. Skip it if you need the smallest tip size available or you rely on a case to keep earplugs clean and findable.
Side-by-Side: Which Should You Choose?
• Best for maximum stated noise reduction → Tphalen 32dB. Its 32dB SNR tops CURVD's 28dB SNR / EPA NRR 20dB.
• Best for very small ear canals → CURVD Ear Plugs. Five tip sizes from XXS to L beat Tphalen's XS to L.
• Best for side sleepers → either, with a caveat. Both use low-profile silicone designed to sit flush; CURVD adds the extra XXS option for tighter canals.
• Best for a no-fuss first fit → Tphalen 32dB. Medium tips come pre-installed, so there is nothing to assemble before your first night.
• Best for a spare in every size → Tphalen 32dB. Four pairs of replacement tips cover XS, S, M and L.
• Best for durability without consumables → both. Neither uses foam; both are reusable, washable silicone.
• Best for travel and commuting → CURVD Ear Plugs. The clip-on case is the difference-maker in a bag or on a keyring.
I would buy the CURVD Ear Plugs. In my opinion, the deciding factor is not the dB number but how often earplugs actually get used — and a plug that fits properly, stays flush through a night of side sleeping, and lives in a case clipped to your bag is a plug you will still be using in six months. The XXS tip size alone makes it the safer pick for smaller ears, and the 28dB SNR with a certified EPA NRR of 20dB covers snoring, traffic and shared walls perfectly well. If you know you want the highest reduction figure on paper, Tphalen 32dB is the honest choice — and its pre-installed medium tips and four-size spare set make it a genuinely easy kit. But for most sleepers, fit wins.
It is a real difference, but not a night-and-day one. Tphalen's 32dB SNR is the higher rating, while CURVD lists 28dB SNR with a certified EPA NRR of 20dB. Both are designed for snoring, traffic and noisy neighbors; the gap matters most in genuinely loud environments.
Which earplugs are better for side sleepers?
Both are low-profile silicone plugs designed to sit flush rather than stick out, which is what side sleepers need. CURVD adds an XXS tip option, so if standard plugs have felt too large or leaked sound at night, that extra size is worth having.
Not strictly, but it helps. CURVD includes an aluminum case plus a clip that attaches to a bag, purse or keys. Tphalen ships without a case, so you would store the plugs in the included tip packaging or your own container.
Both are reusable silicone, not disposable foam. CURVD uses hypoallergenic silicone with five pairs of tips; Tphalen uses pliable skin-friendly silicone with four pairs of tips and is washable for repeated daily use. You clean them rather than toss them.
Decide on fit first, then rating. Want the smallest tip and a clip-on case? Go CURVD. Want the higher 32dB figure and a spare tip in every size? Go Tphalen. Then check the current price on Amazon using the button on this page before you commit.
