If you want an all-in-one open-ear earbud you can wear straight out of the case, choose Ttbesmi Purple Over Open; if you need to keep your existing AirPods 4 locked in place during hard workouts, choose WC HookZ.
• Ttbesmi Purple Over Open's biggest strength: a complete wireless listening system — Bluetooth 5.4, dual mics with environmental noise cancellation, touch controls, a 20-hour charging case with LED readout, and IPX5 sweat resistance.
• Ttbesmi Purple Over Open's biggest trade-off: it's an open-ear, bone-conduction design, so you get situational awareness and comfort instead of deep, isolating bass.
• WC HookZ's biggest strength: a bendable, malleable core that turns your AirPods 4 into hook-secured earbuds with a custom fit.
• WC HookZ's biggest trade-off: it's an accessory, not a headphone — it does nothing on its own and only fits AirPods 4.
• Pick Ttbesmi Purple Over Open if you want one purchase that covers sound, calls, controls and battery.
• Pick WC HookZ if you already own AirPods 4 and only need them to stop falling out.
The Ttbesmi Purple Over Open is a self-contained pair of open-ear sport earbuds. The design hangs over your ears on earhooks rather than sealing into the canal, and it uses a bone conduction driver rated from 20 Hz to 20,000 Hz. The point of that build is awareness: the product's own framing is that you stay tuned in to traffic, people and surroundings while cycling, walking, running, driving or working out. If you've ever felt uneasy wearing sealed buds on a road or in a parking lot, that's the case this product is built for.
On the practical side, it's a fairly complete package. Bluetooth 5.4 handles the connection with a stated range of about 10 meters. Two microphones with environmental noise cancellation work together on calls, and touch controls cover play/pause, call answer/end, volume, track skipping and voice assistant. IPX5 means sweat and rain aren't a concern during a session. Battery is quoted as 4 hours of playback per charge, with the case extending total listening to 20 hours, and the case has a digital LED display that shows the remaining charge in numbers rather than vague dots — a genuinely useful detail when you're heading out the door. Charging the case takes about 4 hours. The whole thing weighs 0.16 kg, and it's packaged as a case-only kit.
Who should skip it: anyone chasing heavy bass or strong passive isolation. Bone conduction and open-ear designs trade that low-end thump for awareness and comfort — that's the nature of the format, not a defect. If you already own AirPods 4 and love them, you don't need this at all. And if you want active noise cancellation rather than environmental noise cancellation on calls, this isn't that product.
WC HookZ: Who It's For
WC HookZ is not a headphone. It's a set of adjustable over-ear hooks designed specifically to be compatible with Apple AirPods 4 — and only AirPods 4. The brand is explicit that it will not work with AirPods Pro, AirPods 1, 2 or 3. Read that twice if you're unsure which model you own, because compatibility is the entire ballgame here.
What makes them interesting is the malleable core inside each hook. You bend it to match your ear shape, and it holds that shape, which is how a one-size accessory gets closer to a custom fit. The outer material is soft, skin-safe silicone with rounded edges, so the hooks add stability without digging in during long listening sessions. Installation is tool-free: you slide your AirPods 4 into the hooks in seconds, and the low-profile design keeps them light enough for daily carry and travel. The stated purpose is simple — stop your earbuds from slipping when you run, cycle or lift. There's also a 365-day full warranty listed. In cyan prism, they're meant to look intentional rather than purely functional.
Who should buy it: AirPods 4 owners whose buds work fine acoustically but won't stay put during activity. If you like how your AirPods sound and just want them anchored, this is the cheaper path by design — you're buying a fit fix, not a new headphone.
Who should skip it: anyone without AirPods 4. Also skip it if you want touch controls, a charging case, a battery indicator or IPX5 protection — none of that lives here, because those features belong to your AirPods. And if your real problem is that you dislike how AirPods 4 sound, hooks won't change that.
• Best for a complete, standalone setup → Ttbesmi Purple Over Open — it includes the earbuds, charging case, controls, mics and battery.
• Best for AirPods 4 owners → WC HookZ — it upgrades hardware you already own instead of replacing it.
• Best for long sessions and battery visibility → Ttbesmi Purple Over Open — 4 hours per charge, 20 hours with the case, and a numeric LED readout.
• Best for sweat and rain → Ttbesmi Purple Over Open — IPX5 is a stated rating; WC HookZ carries no water-resistance claim of its own.
• Best for a truly adjustable fit → WC HookZ — the bendable core lets you shape each hook to your ear.
• Best for situational awareness → Ttbesmi Purple Over Open — the open-ear, bone-conduction design is built around hearing your surroundings.
• Best for calls → Ttbesmi Purple Over Open — dual mics with environmental noise cancellation and touch call control.
• Best for travel and minimal bulk → WC HookZ — a lightweight, low-profile accessory you slide on in seconds.
In my opinion, most people reading this should buy the Ttbesmi Purple Over Open. It's the only one of the two that is a complete product: sound, calls, controls, waterproofing and a 20-hour case with a digital battery display. I'd pick it for running, cycling and gym work, where open ears and a clear battery readout matter more than isolation. I'd only steer you to WC HookZ if you already own AirPods 4, like how they sound, and just need them to stay in your ears — in that specific case, it's the smarter, more targeted fix. Check the current price on Amazon before deciding.
how to wear ear hook earbuds
Hook the curved arm over the top of your ear so the earpiece rests near the ear canal opening without pressing in. On the Ttbesmi Purple Over Open, the earhook holds the bone-conduction driver in place outside the canal; the ergonomic shape distributes weight so it stays put during movement.
how to put on ear clip earbuds
For clip-style hooks like WC HookZ, slide your AirPods 4 into the silicone hook first, then bend the malleable core until the hook follows the curve of your ear. It's tool-free and takes seconds, and you can re-bend it any time the fit feels loose.
are ear hook earbuds good
They're good for a specific job: keeping audio stable during movement and, in open-ear designs, letting you hear your surroundings. The trade-off is less bass and less isolation. If you want punchy, sealed sound, hooks may not be what you're after.
are WC HookZ compatible with AirPods Pro
No. WC HookZ are custom-designed only for Apple AirPods 4 and are not compatible with AirPods Pro, AirPods 1, AirPods 2 or AirPods 3. If you own a different model, these hooks won't fit.
