• LIHOBI Noise Reductution Ear — biggest strength: A 40dB noise reduction rating in a soft, moldable silicone body, plus a waterproof build that's reusable for more than 3 years. Biggest trade-off: It comes as one pair with no extra eartips, and it's a left/right-specific design, so you have to wear it the correct way to get the rated reduction.
• CASCHO Ear Plugs — biggest strength: A higher 45dB rating using a multi-layer acoustic filtration system, and an eight-size eartip system (XS–L) so you can match the fit to your ear canal. Biggest trade-off: It's a newer, more complex product, and the multi-layer system means more parts to keep clean.
• Who LIHOBI is for: Swimmers, side sleepers and anyone who wants one simple, durable pair that just works.
• Who CASCHO is for: People who've struggled to get earplugs to seal properly and want maximum quiet with a customized fit.
• Bottom line: For simplicity and water resistance → LIHOBI. For maximum noise reduction and fit options → CASCHO.
The LIHOBI Noise Reductution Ear is built around one idea: soft silicone that molds to your ear and stays comfortable. The brand calls out German silicone material, and the practical result is a pliable earbud that the manufacturer says fits any ear canal without pressure or pain. If you've ever given up on stiff foam plugs because they made your ears ache by 2 a.m., that moldable quality is the whole point here.
What stands out in the specs is the 40dB noise reduction rating — the brand notes that's roughly 10dB more than similar earplugs. There's one important detail: the plugs are marked "R" and "L," and LIHOBI is explicit that you have to follow the correct wearing steps to actually realize that 40dB figure. So this isn't a toss-it-in-and-hope product; it rewards a little attention to the fit.
The other headline feature is durability and water resistance. The silicone is waterproof, which makes these a genuinely good pick for swimming — the brand specifically mentions reducing the risk of swimmer's ear infection. Cleaning is just a rinse and dry. LIHOBI states the pair can be reused for more than 3 years, and backs it with a 2-year replacement. That long service life is a real reason to consider them over disposable plugs.
Who should skip it: If you have very narrow or unusually shaped ear canals and have never gotten a good seal from a one-size plug, you may want the CASCHO's range of sizes instead. And if you want the absolute highest reduction number available, LIHOBI's 40dB sits below CASCHO's 45dB.
CASCHO Ear Plugs: Who It's For
CASCHO Ear Plugs take the opposite approach: instead of one universal fit, they throw options at the problem. The package includes eight eartips in sizes XS through L. The brand says the design was developed using a database of millions of ear canals, with a 3D contoured shape meant to sit perfectly in different ear shapes. For anyone who's ever had a plug feel loose on one side and tight on the other, that size range is the most compelling part of this product.
On noise reduction, CASCHO claims a professional-grade 45dB using a multi-layer acoustic filtration system with high-density sound-absorbing material. The brand states the precision sealing structure blocks about 90% of environmental noise, and specifically calls out low-frequency sources like airplane engines and construction. There's also a selective frequency filtering feature that the brand says attenuates mechanical low-frequency vibration to avoid constant pressure on your eardrums — a thoughtful touch if pressure buildup is what usually makes you pull plugs out.
Comfort-wise, the eartips are made of an ultra-soft liquid silicone that CASCHO describes as SGS-certified, zero-irritation and anti-allergic, with a vacuum-grade seal you can supposedly wear all night without swelling or pain. The whole set is lightweight and pocketable, with a case included, and the brand says daily cleaning keeps them hygienic. CASCHO frames the reusable design as cutting waste versus disposables, and states the plugs are washable and reusable for up to 6 years.
Who should skip it: If you want the simplest possible routine, the eight-eartip system and multi-layer construction mean more pieces to manage and clean. And if water resistance for swimming is a priority, LIHOBI is the more clearly swim-oriented option.
Side-by-Side: Which Should You Choose?
• Best for maximum noise reduction → CASCHO Ear Plugs (45dB vs LIHOBI's 40dB).
• Best for fit customization → CASCHO Ear Plugs (eight eartip sizes, XS–L).
• Best for swimming and water exposure → LIHOBI Noise Reductution Ear (waterproof silicone, swimmer's-ear angle).
• Best for simplicity → LIHOBI Noise Reductution Ear (one pair, rinse-and-dry, no eartip swapping).
• Best for pressure-sensitive ears → CASCHO Ear Plugs (selective frequency filtering aimed at easing eardrum pressure).
• Best for side sleepers → either, since both use soft silicone earbud designs; CASCHO leans harder on all-night wear in its claims.
• Best for long-term value → CASCHO Ear Plugs on stated lifespan (up to 6 years vs LIHOBI's 3+ years), though LIHOBI includes a 2-year replacement.
• Best for travel kit → CASCHO Ear Plugs (case plus spare eartips included).
• Best for allergy-prone skin → CASCHO Ear Plugs (skin-friendly, anti-allergic silicone).
In my opinion, CASCHO Ear Plugs are the better pick for most people, and it comes down to fit. The single biggest reason earplugs fail is a bad seal, and eight eartip sizes plus a higher 45dB rating directly attack that problem. If you sleep next to a snorer or live near a road, that combination is hard to beat. That said, I'd steer swimmers and anyone who wants zero fuss toward LIHOBI Noise Reductution Ear — the waterproof build, simple one-pair design and 2-year replacement make it the easier daily companion. Check the current price on Amazon before you decide, since both are sold there.
The right answer is whichever seals comfortably in your ear canal, because a good seal is what actually blocks noise. Both of these are soft silicone sleep earbuds, but CASCHO gives you eight eartip sizes (XS–L) to dial in the fit, while LIHOBI offers a moldable single-pair design with a left/right fit. If you've struggled with fit before, more size options usually win.
Yes — both LIHOBI Noise Reductution Ear and CASCHO Ear Plugs are reusable silicone earbuds designed for sleeping. CASCHO states you can wear them all night without swelling or pain, and LIHOBI emphasizes ultra-soft silicone that fits any ear. Neither is an electronic earbud; these are passive noise-blocking plugs.
For LIHOBI, it matters: the plugs are marked "R" and "L" for right and left, and the brand says you must follow the correct steps to achieve the full 40dB reduction. For CASCHO, start by testing eartip sizes to find the one that seals without pressure, then insert so the contoured shape follows your ear canal.
Both are reusable rather than disposable. LIHOBI states its silicone plugs can be used more than 3 years and includes a 2-year replacement. CASCHO states the plugs are washable and reusable for up to 6 years with simple cleaning. In both cases, routine rinsing and drying is what preserves performance.
