• Uonlytech 10pcs — biggest strength: 360° rotatable silicone hooks you can dial in for a precise, secure position on each ear, sold as a 10-piece set of black replacement hooks.
• Uonlytech 10pcs — biggest trade-off: Only 10 hooks, so if you lose them often or want a hook for every pair of earbuds in the house, you'll run out fast.
• Homoyoyo Silicone Earphone Earhook — biggest strength: A 40-piece pack split into 20 left and 20 right covers, so you get far more spares and a clear left/right fit.
• Homoyoyo Silicone Earphone Earhook — biggest trade-off: The hooks are shaped and sized for a left/right orientation rather than being freely rotatable, so fine-tuning the angle isn't part of the design.
• Who each pick is for: Uonlytech 10pcs suits one careful user who wants adjustable, low-profile hooks for running and cycling. Homoyoyo suits families, multi-earbud households, or anyone who wants a big reserve of spares in black and transparent grey.
Uonlytech 10pcs is built around one idea: making a hook that stays exactly where you put it. Each hook is 360° rotatable, which means you can twist it to match the angle of your own ear and the shape of your earbud, then leave it there. That's genuinely useful, because ear shapes vary a lot and a fixed-angle hook can either dig in or sit too loose. The package is 10 black hooks, each measuring roughly 2.01 x 0.94 x 0.14 inches and weighing next to nothing, so once they're on you won't notice them.
The material is silicone, and the manufacturer describes it as able to withstand stretching and bending, which is what you want from a part that gets tugged on and off repeatedly. The overall pitch is anti-loss: the hook grips the earbud and adds a soft anchor behind your ear so the bud doesn't drop out mid-stride. That makes this a sensible pick for running, gym work, cycling, or a commute where you'd rather not stop and hunt for a fallen earbud.
Who should buy it? If you're one person with one or two pairs of earbuds, and you specifically want to adjust the hook angle for a snug fit, this is the more considered option. Who should skip it? If you need hooks for several people, want a ready supply of spares, or prefer a simple push-on left/right cover rather than something you rotate into place, the 10-piece count will feel thin.
Homoyoyo Silicone Earphone Earhook takes the opposite approach: volume and simplicity. The pack contains 40 pieces total — 20 left covers and 20 right covers — which is four times the piece count of the Uonlytech set. The left/right split is the detail that matters most here. Instead of one universal hook you rotate, you get covers shaped for each side, which makes installation almost foolproof: pick the correct side, push it on, done.
The material is again silicone, with the brand emphasising elasticity and toughness, saying the hooks resist deforming or breaking and hold their shape over time. The covers come in black and transparent grey, which is handy if you want to roughly match different earbuds, and each one is about 1.18 x 0.55 x 0.20 inches — compact and, per the listing, lightweight and easy to carry when not in use. The brand also lists an anti-slip function that keeps earbuds from falling out during sport, and notes the covers add a degree of noise isolation, which is a mild side benefit rather than a headline feature. The whole set ships in a bag, and each cover is small enough that a spare can live in a pocket or a bag pocket without notice.
Who should buy it? Anyone buying hooks for more than one person, or for more than one pair of earbuds, gets far more value per piece here. It's also the easier pick if you'd rather not fiddle with angles and just want a cover that goes on the right way. Who should skip it? If you specifically want to rotate the hook to a custom angle, that adjustability isn't part of this design — you're working with a fixed left/right shape.
Side-by-Side: Which Should You Choose?
• Best for a custom, adjustable fit → Uonlytech 10pcs. The 360° rotation lets you set the hook angle to your own ear rather than accepting a fixed shape.
• Best for households or shared earbuds → Homoyoyo. The 20-left/20-right split is designed to cover multiple pairs and multiple people.
• Best for slipping a spare in a pocket → Homoyoyo. Its covers are the smaller of the two (about 1.18 x 0.55 x 0.20 in versus about 2.01 x 0.94 x 0.14 in), and the brand describes them as lightweight and portable.
• Best for colour choice → Homoyoyo. It comes in black and transparent grey; Uonlytech ships in black only.
• Best for a minimalist, single-user setup → Uonlytech. 10 hooks is plenty for one person with one or two earbuds, and you avoid storing a surplus.
• Best if you hate guessing which side is which → Homoyoyo. The left/right labelling removes the trial-and-error of orienting a universal hook.
• Best for sports use in general → both. Both are silicone anti-slip designs aimed at keeping earbuds in place during running, cycling and gym work; the difference is adjustability versus quantity.
If I were buying for myself — one person, one pair of earbuds, mostly running and cycling — I'd take Uonlytech 10pcs. In my opinion the 360° rotatable design is the feature that actually changes how the hook feels day to day, because you can match it to your own ear instead of hoping a fixed shape lines up. Ten hooks is more than enough for a single user, and the slim black profile keeps things tidy. I'd recommend Homoyoyo instead if you're outfitting a family, juggling several earbuds, or simply want a big box of spares with clear left/right covers. Different priorities, both reasonable — just be honest about how many hooks you'll realistically lose.
Not universally. Uonlytech wins on adjustability thanks to its 360° rotatable hooks. Homoyoyo wins on quantity and simplicity with 40 left/right covers. Pick based on whether you value a tunable fit or a large supply of spares.
Uonlytech 10pcs includes 10 black hooks. Homoyoyo includes 40 pieces: 20 left covers and 20 right covers, in black and transparent grey.
Uonlytech describes its hooks as compatible with most brands and types of earphones, and they're designed as universal silicone replacements. Homoyoyo uses left/right-specific covers rather than a universal shape, so fit depends on matching the correct side to your earbud.
Both are silicone. Uonlytech says its hooks withstand stretching and bending; Homoyoyo says its covers resist deforming or breaking and keep their elasticity. Neither brand offers a warranty, so treat them as affordable consumables you replace when they wear out.
That depends on how you'll use them. For one user who wants an adjustable fit, Uonlytech's 10 hooks go further. For multiple people or multiple earbuds, Homoyoyo's 40 covers spread the cost across far more pieces. Check the current price on Amazon for each before deciding.
