How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a passive, battery-free way to mute a noisy room and you like the idea of a reusable plug that never needs charging, choose HeyEars Soft Ear Plugs; if you need in ear noise cancelling earbuds that also play audio, run a Sleep Mode and pair over Bluetooth, choose Houlyn ANC Sleep Earbuds. Those two goals sit at opposite ends of the "quiet" problem, and picking the wrong one means you either carry a charger you don't need or you give up sound you actually want.
• HeyEars biggest strength: certified passive reduction (ANSI NRR 16 dB, SNR 26 dB) in an ultra-soft silicone body with four tip sizes (XS/S/M/L), so you tune the seal instead of hoping one size fits.
• HeyEars biggest trade-off: it is a plug, not a device. No Bluetooth, no audio, no active cancellation — it only blocks sound.
• Houlyn biggest strength: active noise cancelling plus a low-profile, roughly 3g-per-bud mini shape built for side sleepers, with Bluetooth 5.4 and Sleep Mode.
• Houlyn biggest trade-off: it depends on power. Roughly 4–6 hours per charge and up to 30 hours with the case means charging is part of the routine, and ANC is still ANC — it reduces snoring, traffic and air-conditioner hum rather than erasing everything.
• Who each is for: HeyEars for sleepers, students, swimmers and concert-goers who just want the world turned down; Houlyn for anyone who wants quiet and white noise, podcasts or music in their ears all night.
The HeyEars plug is a single-purpose tool, and it's honest about that. It's a soft silicone in-ear plug rated for ANSI NRR 16 dB and SNR 26 dB — that's certified passive attenuation, meaning the reduction happens purely through the physical seal, with no electronics, no pairing and no battery state to think about. You get four tip sizes in the box (XS, S, M, L), which matters more than it sounds: passive plugs live or die by how well they seal, and having four sizes to cycle through gives you a real shot at a custom fit rather than a compromise.
Comfort is clearly the design brief here. The silicone is described as ultra-soft and skin-friendly with an ergonomic shape that stays secure, and the point of that shape is side sleeping — the claim is you can lie on your side without pressure or irritation. That's the classic failure mode of stiff foam plugs, so a soft silicone body is the right call for anyone who rolls onto their side at 3 a.m. It's also reusable and washable, ships in a plastic-free box and stores in a recyclable aluminium case, which is a genuinely nice touch if you're tired of throwing away disposable foam every few nights. The same case clips to a bag, keyring or pocket.
Who should buy it: side sleepers who just want quiet, students and shift workers, swimmers (the plugs are described as waterproof), frequent flyers, and anyone heading to a loud concert or a focus-heavy work session. If you want silence and nothing else, this is the simpler, more predictable purchase.
Who should skip it: anyone who wants to fall asleep to music, white noise or a podcast, take a call, or use active cancellation. The HeyEars plug makes no sound and takes no input — it only subtracts. If you need audio in your ears at night, stop reading this section and go to the next one.
The Houlyn buds attack the same problem from the opposite direction: they don't just block noise, they replace it. Active noise cancelling handles steady background sound — snoring, traffic, air conditioners — while double-layer silicone tips add a passive seal on top. That layered approach is the right one for sleep, because ANC is strongest against constant low-frequency drone and weaker against sharp, sudden sounds; the silicone tips pick up some of that slack.
The shape is the other half of the story. Each bud weighs about 3g and uses a mini, low-profile design specifically so side sleepers don't feel a hard lump pressing into the pillow. That's the detail that separates sleep earbuds from ordinary true-wireless buds — a normal bud with a stem is genuinely painful to lie on. Houlyn also builds in a Sleep Mode that trims interruptions while you drift off, and the audio side is real: a 6mm bio-diaphragm dynamic driver for clear, balanced sound, Bluetooth 5.4 for fast pairing and a stable connection with phones and tablets, and touch controls on the buds themselves.
Battery is where the trade-off lives. You get roughly 4–6 hours per charge, up to 30 hours total with the included charging case, and the kit ships with the two buds, the case, a USB-C cable and a manual. Four to six hours covers a normal night's sleep if you start the buds when you get into bed, but if you sleep eight or nine hours, you'll likely wake to a dead bud — or you'll want to top up the case regularly. That's not a flaw so much as the physics of a 3g bud.
Who should buy it: side sleepers who want white noise, meditation audio or a podcast as they fall asleep; people sharing a bed with a snorer; travelers who want one pair of buds for the plane, the hotel and the bedroom; and anyone who also wants discreet everyday listening, since the mini design is nearly invisible in the ear.
Who should skip it: anyone who wants zero charging, zero pairing and zero setup. If you've ever been woken up by a "low battery" chime, you know exactly who you are.
• Best for pure, no-hassle silence → HeyEars Soft Ear Plugs. Nothing to charge, nothing to pair, nothing to fail.
• Best for side sleeping with audio → Houlyn ANC Sleep Earbuds. The ~3g mini shape and Sleep Mode are built around exactly that.
• Best for blocking snoring and steady background noise → Houlyn ANC Sleep Earbuds, because ANC plus double-layer silicone tips targets the low-frequency drone that keeps people awake.
• Best for concerts, swimming and loud jobsites → HeyEars Soft Ear Plugs. Certified NRR 16 dB / SNR 26 dB protection and a waterproof, reusable build fit those environments better than a pair of music buds.
• Best for travel and commuting → it depends what you want on the journey. Houlyn if you want music and calls; HeyEars if you want to sleep through the engine noise and keep the case on your keyring.
• Best for fit flexibility → HeyEars Soft Ear Plugs, with four tip sizes (XS/S/M/L) versus the fixed double-layer silicone tips on the Houlyn buds.
• Best for all-night wear without charging → HeyEars Soft Ear Plugs. No battery means no 4–6 hour ceiling.
• Best for everyday discreet listening → Houlyn ANC Sleep Earbuds, with Bluetooth 5.4 and a near-invisible fit you can wear to the office.
In my opinion, the right pick comes down to one question: do you want quiet, or do you want quiet plus sound? If you want to fall asleep to white noise, a podcast or calming music — or you share a bed with a snorer and want active cancellation doing the heavy lifting — I'd buy the Houlyn ANC Sleep Earbuds. The 3g mini shape, Sleep Mode, ANC and 30-hour case make it the more complete sleep tool, and the 4–6 hour per-charge limit is a manageable routine rather than a dealbreaker. But if your goal is simply to make the world quieter with nothing to charge, nothing to pair and nothing to think about, I'd buy the HeyEars Soft Ear Plugs — certified 26 dB SNR reduction, four tip sizes and a reusable aluminium case is a cleaner answer to that specific problem than any electronic bud. Check the current price on Amazon for whichever one matches your night.
For sleep specifically, the Houlyn ANC Sleep Earbuds are the stronger pick of these two: they combine active noise cancelling with double-layer silicone tips, weigh about 3g each, and use a mini low-profile shape so side sleepers aren't lying on a hard bud. Note that the HeyEars Soft Ear Plugs reduce noise passively — certified at NRR 16 dB and SNR 26 dB — so they're not "noise cancelling" in the electronic sense.
Neither product here is an over-ear design — both are in-ear. The HeyEars plugs sit inside the ear canal as passive silicone plugs with four tip sizes, and the Houlyn buds are in-ear true-wireless earbuds with ANC and Bluetooth 5.4. If you specifically want an over-ear fit, that's a different category of headphone than either of these.
Yes. The Houlyn buds give roughly 4–6 hours of use per charge, with up to 30 hours total when you use the included charging case, and they charge over USB-C. If you sleep longer than six hours, expect to top up the case regularly. The HeyEars plugs have no battery at all, so charging is never a factor.
Both are designed with side sleepers in mind, but differently. The HeyEars plugs use ultra-soft silicone so you can lie on your side without pressure or irritation, and four tip sizes help you get a secure seal. The Houlyn buds rely on a mini, roughly 3g low-profile body that sits flat in the ear. If you want audio at night, go Houlyn; if you want silence only, go HeyEars.
