If you want a complete replacement kit that fixes both the seal and the fit — new tips and earhooks in three sizes — choose Vezukv Silicone Replacement Earbuds; if you need a single pair of adjustable, rotatable earloops to stop your existing earbuds from working loose, choose Mobestech 10pcs.
• Vezukv's biggest strength: it's a two-part system — 3 pairs of silicone tips (L/M/S, 3.8mm bore) plus 3 pairs of ear fins/earhooks with ridge support. You're replacing the part that seals and the part that grips.
• Vezukv's biggest trade-off: it's a kit, not a universal fix. You need to know your nozzle diameter (it fits 4mm–6mm) and accept a black-only, three-size format.
• Mobestech's biggest strength: the 360° rotatable earloop. Instead of picking a size and hoping, you twist the hook until it locks onto your ear shape.
• Mobestech's biggest trade-off: it's hooks only. There are no replacement tips here, so a bad ear seal stays a bad ear seal.
• Pick Vezukv if: your earbuds sound thin or keep popping out, and you want to refresh the whole interface between you and the earphone.
• Pick Mobestech if: your tips are fine but the buds slide during runs, rides, or long shifts, and you want a quick add-on rather than a rebuild.
The Vezukv kit solves the two most common complaints about in-ear headphones at once. Most earbuds loosen because the tip is the wrong size or the housing has nothing to brace against — the tip seals, but nothing holds. Vezukv ships 3 pairs of silicone tips in L/M/S with a 3.8mm inner bore, and 3 pairs of ear fins/earhooks that add a ridge inside the ear. That ridge is the part doing the real work: it presses against the curve of your ear and resists the outward drift that happens when you run, bend over, or chew.
The specs say the tips fit nozzles between 4mm and 6mm, which covers most wired and wireless in-ear models, and Vezukv specifically names Beats Flex and BeatsX as compatible designs. Note the shape logic here: those Beats models use a wingtip-style housing, so if your earbuds have a similar fin slot, this kit drops in cleanly. If your earbuds are a smooth, wingless barrel, the earhooks may not seat the way they do on a winged design — the description itself warns that these aren't suitable for every earbud and tells you to check your earphone's size and shape first. Take that seriously. Measure your nozzle before ordering.
Material-wise, this is soft, washable silicone with a stated one-year warranty, and the noise-isolating design is about the seal, not electronics — a properly sized silicone tip blocks ambient noise by physically closing the ear canal. The set is black, small (roughly 2 x 2 x 0.25 inches for the kit), and reusable.
Buy it if you want to fix fit and seal in one purchase, you own winged-style in-ears like the Beats models named, or you want spare tips on hand in multiple sizes for different earphones. Skip it if you only need hooks, your nozzles fall outside the 4mm–6mm range, or you want a color other than black.
Mobestech takes the opposite approach: one job, done with adjustability. These are silicone earloops — hooks that wrap over the top of your ear and hold the earbud's cable or housing in place. The headline feature is the 360° rotatable design, which means you can twist the loop to sit wherever your ear anatomy wants it rather than committing to a fixed angle. That's genuinely useful, because ear shape varies far more than earbud shape does.
The hooks are transparent, made of lightweight silicone, and each one measures roughly 2.01 x 0.94 x 0.14 inches — so they're thin and low-profile, intended to disappear against your ear rather than announce themselves. Mobestech describes them as suitable for long wear without fatigue, which follows logically from the material: soft silicone spreads pressure instead of concentrating it at one point. They're also pitched as shareable — the flexible loops adapt to most earbuds and earphones, so a single set can serve several people or several pairs of buds in a household.
What they don't do is change your sound. There's no tip here, no bore diameter, no seal. If your earbuds leak bass or let in train noise because the tip is too small, Mobestech won't help — you'll just be holding a poorly-sealed earbud more securely. The brand also lists no warranty, which is worth knowing before you commit.
Buy it if your existing tips fit well and you simply need anti-slip security for running, cycling, gym work, or all-day wearing. Skip it if you're chasing better isolation or fuller bass, you need replacement tips, or you want a warranty behind the purchase.
Side-by-Side: Which Should You Choose?
• Best for adjustability across different ear shapes → Mobestech. The 360° rotation is the single most flexible feature in this comparison.
• Best for fixing sound isolation and bass → Vezukv. Only Vezukv includes replacement tips, and the seal comes from the tip.
• Best for a quick, low-effort add-on → Mobestech. No sizing decision, no nozzle measurement — just fit the loop and twist.
• Best for households sharing accessories → Mobestech. Flexible loops that adapt to most earbuds suit multiple users.
• Best for multi-size tinkering → Vezukv. Three tip sizes and three fin sizes let you dial in the fit rather than accept it.
• Best for warranty coverage → Vezukv. One year, versus none stated for Mobestech.
• Best for long-wear comfort without pressure → Mobestech. Transparent, ultra-light silicone built around all-day use.
• Best for a complete refresh of an older pair of earbuds → Vezukv. New tips plus new hooks effectively rebuild the worn parts.
In my opinion, Vezukv Silicone Replacement Earbuds is the smarter buy for most people, because fit problems are almost always seal problems too — and only Vezukv addresses both. The three-size tip range plus the ridged ear fins gives you real adjustability, and the one-year warranty backs it up. I'd recommend Mobestech 10pcs instead if your tips already seal well and your only issue is buds slipping out during movement; the 360° rotatable loops are a clever, low-commitment fix for exactly that. Either way, check your earbud nozzle size and shape before ordering, since neither product fits everything.
FAQ
Earhooks stop earbuds from falling out; tips control the seal, isolation and bass. If your buds sound thin or let in outside noise, you need tips — which means Vezukv. If they sound fine but slip, Mobestech's hooks are enough.
Both target active use. Mobestech leans hardest into it with rotatable, non-slip loops for high-impact workouts. Vezukv's ridged ear fins do the same job while also keeping the tip sealed, which matters when you're moving and sweating.
