If you want to protect a pair of Sony WF-C510 earbuds you already own, choose WUNIAK Case Cover; if you need a standalone single-ear Bluetooth headphone for running, cycling or calls, choose LICAEVEY GD28.
These two look like they belong in the same shopping cart, but they are completely different products. One is a protective shell. The other is an actual earbud. That's the whole decision in one line, and everything below explains why.
• WUNIAK Case Cover — biggest strength: it's a purpose-built clear TPU shell for the Sony WF-C510, with a carabiner and a cleaning pen in the box. It protects without hiding the original look of your earbuds.
• WUNIAK Case Cover — biggest trade-off: it is only a case. It produces no sound. If you don't already own Sony WF-C510 earbuds, it's useless to you.
• LICAEVEY GD28 — biggest strength: it's a real, working single-ear open-ear headphone with Bluetooth 5.3, roughly 7 hours of playback and a clip-on hook that stays off your ear canal.
• LICAEVEY GD28 — biggest trade-off: it's mono. One earpiece, one ear. No stereo pair, and the battery is a modest 7 hours, not all-day.
• Who WUNIAK Case Cover is for: WF-C510 owners who want drop and scratch protection plus a way to clip the case to a bag.
• Who LICAEVEY GD28 is for: runners, cyclists and commuters who want one ear free and don't want anything stuffed into their ear canal.
Think of the WUNIAK Case Cover as armor, not audio gear. It's a crystal-clear TPU shell shaped specifically for the Sony WF-C510. Because the material is transparent, the original colorway of your earbuds still shows through — you get protection without turning your case into a plain black blob. The soft TPU absorbs the kind of everyday knocks that happen when a charging case slides off a table or rattles around inside a backpack.
The package is small but genuinely useful. You get the case itself, a metal keychain carabiner, and a cleaning pen. The carabiner is the detail I like most: it turns the case into something you can clip to a belt loop, a tote strap or a gym bag zipper instead of hunting for it at the bottom of a pocket. The cleaning pen addresses the other quiet annoyance with earbuds — earwax and dust building up in the mesh — and having it in the same kit means you're more likely to actually use it.
Installation is meant to be set-and-forget. WUNIAK uses a double-sided adhesive inside the shell so the earbuds don't slip out of the case, and — importantly — the case supports cable charging without being removed. That last point matters more than it sounds. A case you have to peel off every time you charge is a case you'll eventually stop using. Because it's a soft TPU skin rather than a hard shell, expect it to flex and hug the case rather than add bulk.
Who should buy it: anyone who already owns Sony WF-C510 earbuds and wants cheap insurance against scratches and drops, especially if you carry them loose in a bag. Who should skip it: anyone who doesn't own WF-C510 earbuds — the fit is model-specific and won't work on other earbuds — and anyone hoping a case will change how their earbuds sound. It won't. It's a cover.
The LICAEVEY GD28 is a different animal entirely: a single-ear, clip-on, open-ear Bluetooth headphone. It uses Bluetooth 5.3 with a rated range of about 10 meters, and the driver is a 13mm dynamic speaker with a copper ring, tuned across three frequency bands. The design goal is obvious from the spec sheet — this is built for movement, not for critical listening in a quiet room.
The defining feature is the not-in-the-ear fit. The earpiece clips onto your ear rather than plugging the canal, which means no pressure, no swelling, and no soreness during long sessions. If you've ever pulled earbuds out after an hour because your ears felt stuffed, that's the problem this design solves. There's also a magnetic earhook element and an ergonomic shape intended to fit different ear sizes.
Battery life is rated at about 7 hours of working time, with roughly 800 hours of standby and about an hour to charge via the included USB cable. That's a full long run, a bike ride, or most of a workday — but it is not a multi-day battery, so plan on charging between sessions.
Controls are handled by a single multifunction button with a "blind press" layout: one short press to play or pause, a long press to reject a call, a double click for the next track, and three clicks to redial. Once you learn the pattern, you can operate it without looking. That's genuinely useful when your hands are cold, gloved or holding handlebars.
Two practical details round it out. First, IPX4 water resistance: it handles sweat and rain, which is exactly the protection level this kind of sports headphone needs. Second, the leakproof earhole design is meant to keep your audio from spilling out to people standing next to you. The enclosure is ABS plastic in black, and there's a 90-day manufacturer warranty.
Who should buy it: runners, cyclists, walkers and anyone who wants one ear open to traffic or coworkers while taking calls and listening on the move. Who should skip it: anyone who wants stereo music in both ears, or who needs long battery life away from a charger.
• Best for protecting earbuds you already own → WUNIAK Case Cover. It exists purely to shield Sony WF-C510 earbuds from scratches and drops.
• Best for actually listening to something → LICAEVEY GD28. It has a driver, a battery and Bluetooth. The WUNIAK has none of those.
• Best for running, cycling and sweaty workouts → LICAEVEY GD28. IPX4 plus a clip-on, not-in-the-ear fit is designed for exactly this.
• Best for staying aware of your surroundings → LICAEVEY GD28. The open-ear, single-earpiece design leaves one ear free.
• Best for long-wear comfort → LICAEVEY GD28. No ear canal pressure, so no soreness over a long session.
• Best for keeping your case clean and findable → WUNIAK Case Cover. The carabiner clips to a bag, and the cleaning pen handles earbud grime.
• Best for charging convenience → WUNIAK Case Cover. You can charge the earbuds by cable without removing the cover.
• Best for stereo music → neither, honestly. WUNIAK doesn't play audio, and LICAEVEY GD28 gives you one earpiece, not a stereo pair.
• Best if you don't already own Sony WF-C510 earbuds → LICAEVEY GD28. The WUNIAK cover is model-specific and won't fit anything else.
If I had to pick one, I'd buy the LICAEVEY GD28 — but only because it's a complete product rather than an accessory. It plays audio, it survives sweat, it lasts about 7 hours, and it keeps one ear open for traffic. In my opinion, that makes it the more useful purchase for most people reading a comparison like this.
That said, the WUNIAK Case Cover is the smarter buy if you already own Sony WF-C510 earbuds. It's a small, focused accessory that protects a device you've already paid for, and the carabiner and cleaning pen make it a genuinely practical kit. Different jobs, different answers.
FAQ
Just a case. It's a clear TPU protective cover made specifically for the Sony WF-C510, and it includes a keychain carabiner and a cleaning pen. It does not produce sound and does not include earbuds.
No. It's a single-earpiece, clip-on headphone. It's designed so one ear stays open while the other listens — good for running, cycling and staying aware of your surroundings.
The rated working time is about 7 hours, with roughly 800 hours of standby and about 1 hour to charge. That covers a long workout or most of a workday, but not several days of heavy use.
