How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want to fix the earbuds you already own and get serious noise isolation while you listen, choose COMPLY 100; if you need standalone earplugs for sleeping, focus and travel that don't require any electronics at all, choose Yawsoy Noise Cancelling Ear.
• COMPLY 100 — biggest strength: heat-activated memory foam that expands to seal your ear canal, which is exactly what noise isolating sleep earbuds live or die on.
• COMPLY 100 — biggest trade-off: it is not a product on its own. It's a set of replacement tips, so it only helps if you already own compatible Etymotic, Westone, Klipsch, ISOtunes or Jays earbuds.
• Yawsoy Noise Cancelling Ear — biggest strength: soft silicone plugs rated at 40dB SNR reduction, reusable, and sold in four sizes (XS/S/M/L) so you can match your own ear canal.
• Yawsoy Noise Cancelling Ear — biggest trade-off: they block sound, not play it. No audio, no music, no calls — just quiet.
• Who each pick is for: COMPLY 100 is for the listener who wants their existing IEMs to isolate better and stay put. Yawsoy is for the sleeper, traveler or student who wants silence and nothing else.
Think of COMPLY 100 as a tune-up rather than a new device. These are memory foam replacement tips in the Comply 100 Core Series, sold in black, size Large, as three pairs per pack. The material is Comply True Memory Foam, and the whole trick is body heat: the foam warms up, softens, and expands to fill the shape of your ear canal. That expansion is what creates the seal, and the seal is what does the noise isolating work. A good seal also means you hear more bass and more detail at lower volumes, because you're no longer fighting background noise with the volume dial.
The second benefit is grip. Foam conforms to the canal instead of just pressing against it, so the tips hold the earbud in place during workouts, commutes and general movement. Comply also frames these as a comfort fix — the point is to cut the pain and pressure that stock silicone tips can cause after an hour or two, which matters a lot if you're using earbuds at night.
Who should buy it: anyone who already owns compatible IEMs and wants better isolation, a more secure fit and less ear fatigue. Who should skip it: anyone without compatible earbuds, and anyone who wants a product that works on its own.
Yawsoy Noise Cancelling Ear: Who It's For
Yawsoy takes the opposite approach. This is a finished product — reusable silicone earplugs, one pair, in-ear style, black with a matte finish. The headline number is 40dB SNR noise reduction. Just as important is how Yawsoy describes the character of that reduction: balanced, blocking unwanted background noise without cutting off every ambient sound. That's a deliberate design choice, and it's the right one for everyday use, because total isolation can feel disorienting when you're walking, commuting or moving around.
Comfort is the other half of the pitch, and it's where the silicone matters. Soft silicone reduces pressure and irritation compared to firmer materials, and Yawsoy states the ergonomic shape holds a secure fit even while side sleeping. That single detail is why these deserve attention from sleepers: a plug that shifts or pops loose when you roll onto your side is useless by 3 a.m.
Yawsoy also leans into sizing. The plugs come in XS, S, M and L, which is the honest way to sell earplugs — canal size varies enormously between people, and a plug that's too big is painful while one that's too small leaks. There's a sustainability angle too: reusable plugs are cleaned and reused instead of thrown away, which cuts both waste and the ongoing cost of disposables. Use cases Yawsoy names include work, sleep, travel, study, concerts and general noise sensitivity. And yes — they're a sleek-looking object, which is a small thing, but earplugs you're happy to be seen wearing are earplugs you actually wear.
Who should buy it: side sleepers, light sleepers, travelers, students, concert-goers and anyone with noise sensitivity who wants silence without electronics. Who should skip it: anyone who wants to listen to music or take calls — these don't play audio.
• Best for improving earbuds you already own → COMPLY 100. It upgrades isolation, bass and fit on compatible models without buying new earphones.
• Best for sleep, especially side sleeping → Yawsoy. Silicone with a stated secure fit while side sleeping is purpose-built for the bed, and there's no cable or battery to deal with.
• Best for noise isolation as a listening experience → COMPLY 100. The foam seal raises isolation and lets you hear more detail at lower volumes.
• Best for blocking noise without playing anything → Yawsoy. 40dB SNR reduction with no device required.
• Best for fit options out of the box → Yawsoy. Four sizes (XS/S/M/L) versus COMPLY's fixed Large in this listing.
• Best for repeated long-term use → Yawsoy. Reusable and easy to clean; COMPLY's foam is a wear item that you'll replace over time.
• Best for workouts and commuting → COMPLY 100. Memory foam's grip is designed to stop buds slipping during movement and daily activity.
• Best for anyone who wants zero compatibility homework → Yawsoy. It works with your ears, not with a specific list of earbud models.
In my opinion, these two barely compete — they solve different problems, and the right answer depends on whether you want to hear something.
If you already own compatible Etymotic, Westone, Klipsch, ISOtunes or Jays earbuds, I'd buy the COMPLY 100. Memory foam that heat-expands to seal your canal is the single most effective isolation upgrade you can make to gear you already have, and the comfort and grip benefits come along for free.
If you don't, or if your goal is simply to sleep and focus in a noisy room, I'd buy the Yawsoy. Four sizes, soft silicone, a stated side-sleeping fit and 40dB SNR reduction make it the more practical pick for a bedroom. That's the one I'd reach for.
are there earbuds for sleeping
Yes, and there are two routes. You can use earbuds with noise isolating tips like the COMPLY 100 memory foam replacements, which seal the canal for better isolation, or you can use dedicated earplugs like the Yawsoy, which are soft silicone, sized XS to L, and stated to hold a secure fit while side sleeping.
what are the best noise cancelling earbuds for sleeping
In my opinion, the deciding factor is fit, not branding. For listening in bed, compatible IEMs plus COMPLY 100 foam tips give you a heat-activated seal that improves isolation and comfort. For silence only, the Yawsoy plugs are the better fit because they're built for side sleeping with no cable or battery involved.
can you sleep with noise cancelling earbuds
You can, but the design matters more at night than during the day. Anything that presses hard against your ear while you lie on your side gets uncomfortable fast. The Yawsoy plugs are explicitly designed for side sleeping in soft silicone, while COMPLY 100 focuses on reducing the pain and pressure that stock tips cause during long listening sessions.
is it bad to sleep with noise cancelling earbuds
There's nothing in the specs suggesting it's harmful, but two practical points matter. First, fit: pressure and irritation are the real risks, which is why soft silicone and memory foam both exist. Second, awareness: Yawsoy states its plugs block background noise without isolating all ambient sound, which is a sensible balance for everyday and overnight use.
