• Yawsoy Ear Plugs — biggest strength: a full noise-reduction system with a claimed 25–33dB SNR, two earplug heads, and six silicone plus six foam tips across sizes S/M/L, all in a portable case.
• Yawsoy Ear Plugs — biggest trade-off: it is a standalone earplug, not a tip for earbuds you already own, and it reduces noise rather than silencing it completely.
• Klowcok Replacement Ear Tips — biggest strength: purpose-built soft silicone tips that fit Soundcore Sleep A20 / A30 earbuds, three pairs in S/M/L, easy to swap and wash.
• Klowcok Replacement Ear Tips — biggest trade-off: it is only a tip set — no earbuds included — so it is useless unless you already own the matching Soundcore model.
• Who each pick is for: Yawsoy if you want one kit for sleep, snoring partners, work, travel, motorcycles and concerts; Klowcok if you own Soundcore Sleep A20 / A30 buds and want a comfortable, hygienic refresh.
Yawsoy Ear Plugs are built as a complete hearing-protection kit rather than a single pair of plugs. The box gives you 2 pairs of earplug heads, 3 sets of soft silicone ear tips (S/M/L), 3 sets of foam ear tips (S/M/L), a portable storage box and instructions. That matters more than it sounds. Ear canals vary a lot, and the difference between a plug that seals and one that leaks is usually the tip, not the plug. Having both silicone and foam in three sizes means you can experiment until you find the combination that actually stays put through a night's sleep.
The headline number is a noise reduction rating of 25–33dB. Read that honestly: it is meaningful reduction, not silence. Yawsoy says this itself — the plugs block noise and reduce its impact, but they will not make the world completely silent. In practice that is the right expectation for a snoring partner, a noisy street, a shared office or a long flight. It will take the edge off and let you settle, and it will not erase a leaf blower two metres away.
The design choices point to a general-purpose tool. It is an earbud-style plug in black silicone, and the silicone surface is smooth, which makes it less likely to collect dust and easier to wipe clean — a real advantage if you use the same plugs every night. The listed uses cover sleeping, partner snoring, working, studying, travelling, motorcycles and concerts, which is a wide net, and Yawsoy offers five colour options if you care how they look.
Who should buy it: anyone who wants one kit that handles sleep, focus and loud environments, and who is willing to spend a few minutes finding their size. Who should skip it: anyone who already owns Soundcore Sleep A20 / A30 earbuds and just needs fresh tips — this is a different product category. Also skip it if you expect total silence; no passive plug at this rating delivers that.
Klowcok Replacement Ear Tips are a maintenance part, and they are honest about it. They are silicone tips made specifically to fit Soundcore Sleep A20 / A30 earbuds, sold as 3 pairs in S/M/L — one pair per size. The listing is explicit that the earbud itself is not included. If you own those buds, that is exactly what you want; if you do not, this product has no use to you at all.
The appeal here is straightforward. Ear tips are the part that touches your skin, collects earwax and body oils, and eventually loses its grip and its seal. Klowcok describes the tips as high-quality and lightweight, easy to replace, securely fitting, washable, and offering effective noise blocking. Because they are silicone, they can be rinsed and reused, which is the practical reason people buy replacement tips in the first place rather than replacing whole earbuds.
Sizing is the quiet hero. Three pairs in small, medium and large let you find the size that seals your ear canal properly — and a proper seal is what makes noise isolation work on a sleep bud. A tip that is too small leaks; one that is too large can feel tight and itchy. Having one pair of each size also means you can keep a spare set for travel or hand one to a partner.
Side-by-Side: Which Should You Choose?
• Best for blocking snoring and general noise → Yawsoy Ear Plugs. The 25–33dB rating and dual silicone/foam tips are aimed squarely at sleep and shared rooms.
• Best for refreshing earbuds you already own → Klowcok Replacement Ear Tips. It exists only to serve Soundcore Sleep A20 / A30 buds.
• Best for fit flexibility → Yawsoy Ear Plugs. Two materials across three sizes beats three silicone sizes, because foam and silicone seal differently.
• Best for hygiene on a sleep bud → Klowcok Replacement Ear Tips. Washable silicone tips that swap out in seconds are the simplest fix for worn or grimy tips.
• Best for travel, work, concerts and motorcycle use → Yawsoy Ear Plugs. The listed use cases and the included storage box make it a portable all-rounder.
• Best if you want everything in one box → Yawsoy Ear Plugs. Plugs, tips, case and instructions arrive together; Klowcok assumes you already have the hardware.
• Best if you only need a spare set → Klowcok Replacement Ear Tips. Buying a whole new plug kit to fix a tired tip would be overkill.
• Best for a gift or a first-time buyer → Yawsoy Ear Plugs. It works out of the box with no other purchase required.
For most people reading this, I would buy Yawsoy Ear Plugs. In my opinion it is the more useful purchase because it stands alone: you get the plugs, two tip materials, three sizes each, and a case, and it covers sleep, study, travel and loud events without needing anything else. I would only pick Klowcok Replacement Ear Tips if I already owned Soundcore Sleep A20 or A30 earbuds and my problem was worn, uncomfortable or unhygienic tips — in that case Klowcok is the correct, targeted fix. Check the current price on Amazon for whichever one matches your situation, since that is the number that decides it.
FAQ
how to put on silicone earbuds
what are the best earbuds to sleep in
The best sleep earbuds are the ones that sit flat, seal well and stay comfortable on your side. This page compares a standalone plug kit against replacement tips, not earbuds themselves. If you already use Soundcore Sleep A20 / A30 buds, Klowcok's soft silicone tips in S/M/L are designed as the direct fit; if you want no electronics at all, Yawsoy's plugs are the alternative.
are there earbuds for sleeping
Yes. Dedicated sleep earbuds exist, and Soundcore's Sleep A20 / A30 are the models Klowcok makes replacement tips for. Those tips are silicone, lightweight and washable, with effective noise blocking, and they come in three sizes. If you would rather avoid earbuds entirely, passive earplugs like Yawsoy's reduce noise by a rated 25–33dB instead.
do I need replacement ear tips or a whole new earplug set
It comes down to what you already own. If you have Soundcore Sleep A20 / A30 earbuds and only the tips are worn, Klowcok's 3-pair S/M/L set is the smaller, more sensible fix. If you own nothing and want noise reduction for sleep, work, travel or concerts, Yawsoy Ear Plugs give you the complete kit with silicone and foam tips, a case and instructions.
