• CURVD Ear Plugs — biggest strength: a 28dB SNR (EPA NRR 20dB) silicone plug with five tip sizes (XXS–L), a satin nickel case clip, and a genuinely low-profile shape built around side sleepers. Biggest trade-off: lower rated reduction than the TOAPEX, so very loud snoring or traffic may still creep through.
• TOAPEX 45dB — biggest strength: a 45dB hearing-protection rating using a multi-layer sound insulation design, plus eight pairs of eartips (XS–L). Biggest trade-off: the higher rating and larger tip bundle mean a bulkier kit to manage, and the brand is newer to the category.
• Who CURVD is for: light sleepers with smaller ear canals, side sleepers, frequent flyers, and anyone who wants one clean kit that clips to a bag.
• Who TOAPEX is for: people chasing maximum rated reduction for snoring, concerts, shooting, or motorcycle use, and anyone who wants spare tips in several sizes.
• Bottom line: pick CURVD for fit flexibility and a sleep-first low profile; pick TOAPEX if the number 45dB is what convinces you to stop hearing your neighbor.
CURVD positions this pair as an everyday noise blocker rather than a specialist tool. The headline spec is a 28dB SNR rating with an EPA NRR of 20dB, and the plugs are made from soft, reusable silicone rather than disposable foam. That matters for anyone who has gotten tired of squashing foam cylinders every night and tossing them in the bin. The purple colorway, aluminum carrying case, and case clip round out a kit that feels designed to live on a nightstand or a backpack strap.
In my opinion, this is the pick for the traveler and the light sleeper who wants one pair that does sleep, flights, focus work, and the occasional loud room. It's also a sensible choice for neurodivergent students and professionals who need to dial down background noise without fully sealing off the world. Skip it if your problem is industrial-level sound — a snoring partner two feet away, a flight path overhead, or a drum kit in the next room. At 28dB SNR, CURVD is a strong everyday filter, not a maximum-reduction tool.
TOAPEX 45dB: Who It's For
TOAPEX goes straight for the number. This pair advertises 45dB of hearing protection, achieved through a multi-layer sound insulation design that combines high-density materials with acoustic filtering. The brand claims the filter blocks disruptive noise like snoring and conversation while preserving clarity for concerts, which is the classic trade-off argument for filtered earplugs: reduce the volume, not the music. Whether or not 45dB is achievable in every ear canal, the design intent is clearly maximum reduction with minimal distortion.
Comfort and fit get real attention here too. The plugs use ultra-soft silicone with a 3D ergonomic shape meant to mold to the ear canal, and the kit includes eight pairs of eartips in XS, S, M, and L — two pairs of each. TOAPEX claims that spread fits 95% of ear shapes. The housing uses a combination of ABS and silicone with a matte finish and metallic color plating, which is a more fashion-forward look than most sleep earplugs bother with. A mini storage case keeps everything together.
The use-case list is broad and specific: sleep, snoring, concerts, festivals, motorcycle riding, shooting, airplane pressure changes, and tinnitus relief. That's a lot of jobs for one product, and it tells you the target buyer isn't only a sleeper — it's someone who wants one pair of reusable plugs for loud environments across the board. Skip TOAPEX if you want the absolute slimmest plug for stomach or side sleeping, or if you prefer a single well-defined kit over a pile of spare tips. And if you've had trouble with earplugs feeling bulky, the higher-density multi-layer build may be less forgiving than a simple silicone dome.
• Best rated noise reduction → TOAPEX 45dB. Its 45dB rating and multi-layer insulation design target the loudest environments.
• Best for smaller ears → CURVD Ear Plugs. The XXS tip size reaches canal sizes TOAPEX doesn't cover.
• Best tip variety → TOAPEX 45dB. Eight pairs across XS–L, including two pairs of every size.
• Best low-profile sleep design → CURVD Ear Plugs. The shape is explicitly built around side sleepers and pillow contact.
• Best for concerts and loud events → TOAPEX 45dB. The frequency-filtering claim is aimed at preserving music clarity while cutting volume.
• Best travel kit → CURVD Ear Plugs. The aluminum case and satin nickel clip make it easy to keep the plugs clean and attached to a bag.
• Best for general focus and sensory overload → CURVD Ear Plugs. A 28dB everyday filter is usually enough for offices, commutes, and study.
• Best for maximum-environment versatility → TOAPEX 45dB. Sleep, snoring, flights, motorcycling, and shooting all fall inside its stated range.
If I were buying one pair for sleeping, I'd take the CURVD Ear Plugs. The five-size tip range is the thing that actually determines whether an earplug works for you, and the low-profile shape is purpose-built for side sleepers — which is how most people actually sleep. The 28dB SNR rating is honest everyday protection, and the case clip means the plugs stay clean instead of rolling around a drawer.
That said, if your bedroom backs onto a highway or your partner snores like a chainsaw, the TOAPEX 45dB is the more aggressive tool and the better fit for loud environments beyond the bedroom. Match the product to the noise, not the other way around. Whichever you pick, check the current price on Amazon before you commit.
FAQ
Yes — reusable in-ear plugs like these are made specifically for sleep. CURVD uses soft silicone with a low-profile shape for side sleepers, while TOAPEX uses ultra-soft silicone with a 3D ergonomic design. Neither is a powered earbud; both are passive noise blockers you insert and wear overnight.
what are the best noise cancelling earbuds for sleeping
If "best" means the highest rated reduction, TOAPEX 45dB claims 45dB with a multi-layer insulation design. If "best" means fit and comfort for side sleeping, CURVD's 28dB SNR plug with five tip sizes (XXS–L) is the more sleep-focused option. In my opinion, fit matters more than the rating for all-night wear.
can you sleep with noise cancelling earbuds
Yes, provided they're designed for it. Both of these are reusable silicone plugs rather than battery-powered devices, so there's nothing to charge and nothing to overheat. CURVD is explicitly built for side sleepers, and TOAPEX lists side sleepers among its intended users.
is it bad to sleep with noise cancelling earbuds
Passive earplugs like these are a normal sleep aid — the main risk is discomfort or pressure from a poor fit, not the plugs themselves. That's why tip sizing matters: CURVD says to size up if noise gets through and size down if you feel pressure, and TOAPEX includes four sizes across eight pairs. If you have ear or hearing concerns, talk to a clinician.
