• CURVD Ear Plugs — biggest strength: Rated 28dB SNR (EPA NRR 20dB) with five tip sizes from XXS to L, so you can tune the seal instead of settling for "close enough."
• CURVD Ear Plugs — biggest trade-off: These are earplugs, not headphones. No audio, no mic, no cable. They block sound and nothing else.
• PENGARO iPhone 17 — biggest strength: A Hi-Res DAC chip, dynamic drivers and passive noise isolation in a wired USB-C package that covers an enormous list of phones, tablets and laptops.
• PENGARO iPhone 17 — biggest trade-off: The seal depends on three silicone tip sizes (S/M/L) and a half-ear fit, and the 4ft cable is still a cable — a real consideration if you move a lot at night.
• Who CURVD is for: Side sleepers, light sleepers and anyone whose main enemy is noise, not silence.
• Who PENGARO is for: People who want one wired pair for sleep, commuting, calls and gaming without juggling a charging case.
CURVD Ear Plugs are built around one job: making the room quieter. The headline number is a 28dB SNR rating, with EPA NRR 20dB certification, which tells you these are positioned as genuine hearing protection rather than a soft accessory. In practice that's the difference between "I can still hear the neighbor's bass" and "the snoring is a background hum." The soft, reusable silicone body is designed for all-night wear, and there's no foam to replace every week — you rinse them, dry them, and they go back in the case.
The fit system is where CURVD earns its keep. Five tip sizes run from XXS to L, and the brand's own logic is simple and useful: if noise leaks through, size up; if you feel pressure, size down. That's a surprisingly practical troubleshooting rule, especially if you've ever abandoned earplugs because they hurt after an hour. The low-profile shape is explicitly aimed at side sleepers, so your ear isn't fighting a lump against the pillow. A case clip attaches to a gym bag, purse, keys or backpack, which matters more than it sounds — earplugs that live loose in a pocket collect lint and lose their seal.
PENGARO iPhone 17: Who It's For
The PENGARO iPhone 17 is a wired USB-C earphone that happens to be unusually well suited to sleep and rest, mostly because of what it isn't: there's no battery to die at 3 a.m., no Bluetooth pairing to redo, and no charging case to lose under the bed. It uses a USB-C plug and claims compatibility across a genuinely wide spread of devices — iPhone 17 Pro Max/17 Pro/17 Air/17/16e/16 series and iPhone 15 series, iPad Pro, MacBook Air M4 and MacBook Pro, Galaxy S25/S24/S23 lines and Z Fold/Z Flip models, Google Pixel 10 and 9 series, OnePlus, and "all USB-C devices without 3.5mm jack."
Inside, a Hi-Res DAC chip handles the digital-to-analog conversion, and the dynamic drivers are tuned for balanced bass, mids and highs. The noise control is passive: the in-ear design physically plugs the canal, and you get three silicone tip sizes (S/M/L) to dial in the seal. That's the same physics earplugs rely on, just with audio attached. The 4ft lightweight cable includes a clip to keep it tangle-free, and the half-ear ergonomic shape is designed to reduce fatigue during extended wear — the brand specifically calls out sleeping, commuting and workouts. There's also a built-in microphone, so calls and voice chat work without pulling the buds out. One honest caveat from the specs: PENGARO notes that if audio cuts out, you may need to enable "USB audio routing" in Developer Options on some devices.
Buy PENGARO if: you want one wired pair that handles music, podcasts, calls and gaming, and you're comfortable sleeping in something with a cable. Skip it if: you need maximum passive blocking with zero hardware, or you want a completely cable-free night.
• Best for pure noise blocking → CURVD Ear Plugs. 28dB SNR and a 20dB EPA NRR rating is the whole point of the product.
• Best for side sleepers → CURVD Ear Plugs. The low-profile shape is designed to sit flush, and five tip sizes (XXS–L) let you fix pressure or leakage without guesswork.
• Best for audio at night → PENGARO iPhone 17. Hi-Res DAC, dynamic drivers and a built-in mic mean you can actually listen, not just mute the world.
• Best for small ears → CURVD Ear Plugs. XXS exists. PENGARO starts at S.
• Best for device flexibility → PENGARO iPhone 17. The compatibility list spans iPhone, Galaxy, Pixel, OnePlus, iPad and MacBook over USB-C.
• Best for zero maintenance → tie, leaning CURVD. No battery and no firmware anywhere, though both need their tips kept clean.
• Best for calls and gaming → PENGARO iPhone 17. The mic and the clip-equipped 4ft cable are aimed squarely at that.
• Best for travel and commuting → CURVD Ear Plugs if you want blocking only; PENGARO iPhone 17 if you want blocking plus sound.
In my opinion, most people searching for "noise isolating sleep" should start with CURVD Ear Plugs. The 28dB SNR rating, the XXS-to-L tip range and the side-sleeper-friendly profile attack the actual problem — noise — with nothing to charge and nothing to fail. I'd pick PENGARO iPhone 17 instead if you want your sleep audio to be the point: wired USB-C, a Hi-Res DAC, a mic, and passive isolation that comes from the same in-ear seal principle. If you can only buy one and your goal is silence, buy the CURVD. Check the current price on Amazon before you commit.
are there earbuds for sleeping
Yes. The PENGARO iPhone 17 is explicitly described as suitable for sleeping thanks to its ergonomic in-ear shape and low-fatigue design, and the CURVD Ear Plugs are a sleep-first product with a low-profile shape aimed at side sleepers. The main difference is that one plays audio and the other only blocks it.
what are the best noise cancelling earbuds for sleeping
For blocking alone, the CURVD Ear Plugs are the stronger pick on paper with a 28dB SNR rating and EPA NRR 20dB. For listening plus isolation, the PENGARO iPhone 17 uses passive noise cancellation through its in-ear seal and three silicone tip sizes. Neither uses active electronics to cancel sound.
can you sleep with noise cancelling earbuds
It's physically possible with both. CURVD is designed for all-night comfort in soft silicone, and PENGARO's half-ear fit and clip-equipped 4ft cable are built for extended wear. The practical question is whether a cable bothers you — if it does, the earplugs are the easier sleep.
is it bad to sleep with noise cancelling earbuds
There's nothing in either spec sheet suggesting these are unsafe for sleep. The real risks are comfort and fit: pressure from a tip that's too large, or a seal that's too loose to block anything. CURVD's size-up/size-down rule and PENGARO's three tip sizes both exist to solve exactly that.
