• COMPLY TW-200-C — biggest strength: Comply True memory foam that expands to grip your ear canal, so your earbuds stop falling out and external noise drops. Biggest trade-off: it isn't a product on its own — it only works if you already own a compatible set of earbuds, and the foam needs gentle care.
• LOETRUY 2 — biggest strength: a self-contained hearing-protection kit with a stated 25dB–30dB noise reduction rating, 2 pairs of plugs, 8 pairs of tips and a connector cord. Biggest trade-off: it's silicone earplugs, not audio tips — it won't improve or replace the sound of any earbuds.
• Who COMPLY TW-200-C is for: earbud owners whose tips keep slipping out or letting noise in.
• Who LOETRUY 2 is for: anyone who needs to turn down the world — concert-goers, musicians, light sleepers, people in loud workplaces.
The COMPLY TW-200-C is a three-pair pack of medium memory-foam replacement ear tips in Comply's TrueGrip Black foam. The whole point of this product is fit. Silicone tips sit against your ear canal; memory foam is designed to expand and press gently outward, which is what gives it that grip. Comply builds these to a specific length and shape for a deep, stable in-ear seat, so the tip stays put whether you're running, lifting, cycling or just moving around the house.
The compatibility list is the other half of the story, and it's long: Beats Studio Buds and Beats Fit Pro, OnePlus Buds Z, Huawei Freebuds 4i, Tozo T6/T8/T10/T12, JBL Tune T120TWS and Tune 120, UA Flash, Lypertek Tevi, SoundPEATS Capsule3 Pro, Anker Soundcore Space A40, Sennheiser Momentum 1/2, CX Plus, CX TW, CX 400BT and Sport True Wireless, Audio-Technica ATH-TWX9, Master & Dynamic MW08, Final ZE 3000, Raycon Work Earbuds Classic and EarFun Free Pro. Notably, the design is stated not to interfere with charging, so you can leave them mounted in the case.
Who should buy it: if your earbuds loosen up mid-workout, if you're constantly pushing them back in, or if you want more isolation on a commute or a flight, this is a targeted fix. The foam seals your canal more completely than a stock silicone tip, which in Comply's words blocks exterior noise and enhances bass — that's the practical payoff of a better seal, not a magic sound upgrade.
LOETRUY 2: Who It's For
The LOETRUY 2 is a completely different animal: a reusable hearing-protection kit built around silicone earplugs with a stated noise reduction rating of 25dB–30dB. The pitch is "still hear everything, just quieter" — these are designed to knock loud environments down to a comfortable level rather than mute the world entirely. That's exactly what you want at a live show, a music festival, a nightclub or a bar, where you want the music but not the ringing ears afterward.
The fit system is unusually generous for this category. You get 2 pairs of earplugs, 5 pairs of soft ear tips and 3 pairs of double-layer ear tips, which means you can size up if the plugs feel loose or size down if they hurt or stick out. The shape is designed to sit tightly and resist falling out, and since everything is skin-friendly silicone, LOETRUY positions it for all-day wear.
The accessories are where this kit separates itself from a bare pair of plugs: a connector cord for the two earplugs, a black carrying box, a round key chain ring and a cable buckle. The cord matters more than it sounds — at a concert or a festival, one bumped elbow and a loose plug is gone forever. The key chain ring means the case rides with you, which is the difference between actually using hearing protection and leaving it in a drawer.
Who should buy it: concert and festival regulars, musicians and crew, club-goers, light sleepers, and anyone working around sustained loud noise. The color is pink, the silicone is soft, and the kit is built to be reused rather than thrown away.
Side-by-Side: Which Should You Choose?
• Best for keeping earbuds in during workouts → COMPLY TW-200-C. Memory foam grip is the entire design brief.
• Best for concerts, festivals and live music → LOETRUY 2. The 25dB–30dB rating and connector cord are built for exactly that scenario.
• Best for sleep and light sleepers → LOETRUY 2. Silicone plugs sized three ways are far more practical for side-sleeping than foam tips on earbuds.
• Best for better isolation and bass from earbuds you already own → COMPLY TW-200-C. A deeper foam seal is what does the work.
• Best for loud workplaces → LOETRUY 2. Reusable, wipeable, with a carry case that clips to a key ring.
• Best for long-term value → depends on the job. Foam tips are a consumable you'll rebuy; silicone plugs are reusable. Check the current price on Amazon for both before deciding, since that's the only way to judge which makes sense for your budget.
• Best all-in-one kit → LOETRUY 2. Two pairs of plugs, eight pairs of tips, cord, case, ring and buckle out of the box.
• Best for someone who owns none of the compatible earbuds → LOETRUY 2. It works on its own; COMPLY TW-200-C does not.
If I had to pick one, I'd buy the LOETRUY 2 — but only because it solves a problem for more people. It's a complete, reusable kit that works the moment you open it, with enough tip sizes to actually dial in a fit and a cord that keeps a plug from vanishing at a show. In my opinion, the COMPLY TW-200-C is the better product for a narrower job: if you already own compatible earbuds and they keep slipping or leaking noise, memory foam is the fix, and nothing else here replicates it. Buy the COMPLY if that's your problem. Buy the LOETRUY 2 if you just want the world turned down.
They reduce noise in different ways. COMPLY relies on a memory-foam seal inside your ear canal while you wear earbuds. LOETRUY states a 25dB–30dB reduction rating as standalone plugs. For blocking loud environments without any earbuds, the LOETRUY 2 is the more direct tool.
Check the compatibility list first. It covers Beats Studio Buds and Fit Pro, OnePlus Buds Z, Tozo T6/T8/T10/T12, JBL Tune T120TWS, Sennheiser Momentum and CX models, SoundPEATS Capsule3 Pro, Anker Soundcore Space A40 and more. If your model isn't listed, don't assume a fit. This pack is medium only.
Yes — both are stated use cases. The kit includes three tip sizes so you can go smaller if the plugs hurt or stick out, and the connector cord keeps them together in crowds. The silicone is described as skin-friendly for all-day wear.
They're not competing for the same job, so value depends on your need. Foam tips are a consumable you'll replace over time; silicone earplugs are reusable. Compare the current prices on Amazon and weigh that against how often you'd actually use each one.
