If you want a universal replacement kit that adds real earhook grip to almost any in-ear headphone you already own, choose Vezukv Silicone Replacement Earbuds; if you need purpose-built ear tips and hooks made specifically for the Beats Studio Buds and Studio Buds+, choose Luckvan Silicone. That's the short version. Both are silicone accessory kits built around the same core idea — keep your earbuds from sliding out — but they solve the problem from two very different directions, and picking the wrong one is mostly a question of which earbuds you actually own.
• Vezukv's biggest strength: a broad universal kit — 3 pairs of ear tips and 3 pairs of ear fins/earhooks in L/M/S, with a 3.8mm bore that fits 4mm–6mm nozzles.
• Vezukv's biggest trade-off: "universal" means it fits many earbuds but is not shaped for any one model, and 3.8mm tips won't work on nozzles outside that range.
• Luckvan's biggest strength: a 1:1 design made specifically for the Beats Studio Buds and Studio Buds+, with extra-small tips aimed at narrow ear canals.
• Luckvan's biggest trade-off: it's a one-model accessory — if you don't own Studio Buds or Studio Buds+, it isn't for you, and the earhooks come in medium only.
• Pick Vezukv if you want to fix the fit of a mixed drawer of wired and wireless in-ears, especially for sports.
• Pick Luckvan if your Studio Buds tips hurt, slip, or fall out and you want a model-specific replacement.
The Vezukv kit is essentially a fit-repair toolbox. You get three pairs of silicone ear tips in large, medium and small with a 3.8mm inner bore, plus three pairs of ear fins/earhooks in the same three sizes. The stated compatibility window is 4mm–6mm nozzles, which the listing frames as covering most wired and wireless Bluetooth earphones — including Beats Flex and BeatsX-style housings and similar designs. The earhooks use a ridge-support shape, which is the part that does the actual work: instead of relying on the tip alone to hold the bud in your ear, the fin presses against the curve of your outer ear and resists the downward pull that makes earbuds work loose mid-run.
That combination — multiple tip sizes plus matching fins — is what makes it useful for people who own several pairs of earbuds and are tired of one pair staying put while another slides out on the treadmill. The silicone is soft, washable and reusable, and the listing describes it as gentle enough for long wear without squeezing your ear. Noise isolation comes from the tip seal itself: a better-fitting silicone tip blocks more ambient noise, which makes music and calls clearer at the same volume. There's also a one-year warranty noted on the spec sheet.
Who should buy it: anyone with in-ear headphones in the 4mm–6mm nozzle range who wants a secure, sport-ready fit and doesn't mind doing a little size trial-and-error to get there. It's also a sensible pick if you alternate between a couple of different earbuds and want one kit that covers them. Who should skip it: if your earbuds have nozzles outside that 3.8mm bore range, or if you own Beats Studio Buds specifically — those have their own dedicated shape, and a universal kit is the wrong tool. Also skip if your earhook channel isn't compatible; the listing is upfront that these parts don't fit every earbud, so checking your nozzle size and hook shape before buying matters.
Luckvan takes the opposite approach: it isn't trying to fit everything, it's trying to fit one thing extremely well. This kit is made for the Beats Studio Buds and Studio Buds+, and the fit is described as a 1:1 original design — meaning the tips and hooks are shaped to match the Studio Buds housing rather than approximate it. The bundle is two pairs of anti-slip earhooks (medium size) plus two pairs of extra-small ear tips, along with a silicone storage box.
The extra-small tips are the headline feature here. If you have narrow ear canals, the stock tips on many earbuds simply don't seal — they sit loose, leak bass, and start to ache after an hour. Luckvan's whole pitch is that pain-free alternative: soft, washable, ear-gentle silicone in a genuinely small size, so the tip seats properly instead of being crammed in. The earhooks carry ridge support too, so they grip the ear and hold the bud during hard exercise rather than letting it pop out on a sprint or a heavy set.
The 1:1 shaping also means installation is a non-event: they go on and come off easily for daily swapping, and because they're built to the Studio Buds dimensions, you're not fighting a universal tip that's slightly off. There's a one-year warranty noted as well.
Who should buy it: Beats Studio Buds or Studio Buds+ owners whose original tips hurt, won't seal, or keep falling out — particularly people with smaller ear canals who've struck out with the stock sizes. Who should skip it: anyone who doesn't own Studio Buds or Studio Buds+. Because it's model-specific, it won't help a drawer full of other earbuds, and the earhooks only come in medium, so if you need a different hook size you're out of options here.
• Best for secure fit on a mix of earbuds → Vezukv Silicone Replacement Earbuds. Three tip sizes and three fin sizes cover more hardware.
• Best for Beats Studio Buds / Studio Buds+ → Luckvan Silicone. The 1:1 design removes the guesswork.
• Best for small ear canals → Luckvan Silicone. It's the only one of the two that ships extra-small tips.
• Best for sports and running → both, with a caveat. Both use ridge-supported earhooks to resist slipping; Vezukv's advantage is choice of fit, Luckvan's is a precise fit for one model.
• Best for noise isolation → Vezukv Silicone Replacement Earbuds. Its sound-isolating tip design is stated across three sizes, so you can dial in a proper seal.
• Best for a one-model, low-fuss replacement → Luckvan Silicone. Easy install and removal for daily use.
• Best for owners of multiple brands → Vezukv Silicone Replacement Earbuds. The 4mm–6mm nozzle range and bundled fins make it the more flexible kit.
• Easiest to get right the first time → Luckvan Silicone. If you own the target model, there's no size guessing.
In my opinion, the deciding factor here isn't the silicone — it's your earbuds. If you own Beats Studio Buds or Studio Buds+ and the fit is the problem, I'd buy Luckvan Silicone: the 1:1 design and extra-small tips solve a specific, common complaint, and there's no trial-and-error. For everyone else — a mixed drawer of wired and wireless in-ears, a workout pair, anything in the 4mm–6mm nozzle range — I'd go with Vezukv Silicone Replacement Earbuds. The three-size tip and fin set gives you more ways to chase a secure fit, and the ridge-supported hooks are exactly what keeps a bud planted during exercise. Check the current price on Amazon before you commit, since both are accessories you'll want to size correctly.
Luckvan. It's built specifically for the Studio Buds and Studio Buds+ with a 1:1 design and extra-small tips. Vezukv is a universal kit, so it's not shaped for that model.
Only if your nozzles are in the 4mm–6mm range, since the tips have a 3.8mm inner bore. If your earbuds fall outside that, look elsewhere — and check your earhook shape too.
Both use ridge-supported earhooks that grip the ear to resist slipping during exercise, which is the design intent. The result still depends on matching the right tip and hook size to your ear.
That's their main purpose. The kit includes two pairs of extra-small tips for narrow ear canals, aimed at people whose stock tips feel uncomfortable or won't seal.
