How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a playful, waterproof silicone shell for your Bose Ultra Open Earbuds charging case, choose TSVSXS Silicone Case Compatible; if you need a Sony WF-C510 cover with a cleaning pen and a metal carabiner, choose WUNIAK Case.
• TSVSXS Silicone Case Compatible — biggest strength: a full-body silicone shell with a game-console design, keychain included, and a waterproof rating, sized specifically for the Bose Ultra Open Earbuds (2024) charging case.
• TSVSXS Silicone Case Compatible — biggest trade-off: it is a single-model case, so if you own any other earbuds it simply will not fit, and the game-button styling is a strong look you either love or don't.
• WUNIAK Case — biggest strength: it bundles more into the box — silicone cover, metal carabiner, cleaning pen and lanyard — for the Sony WF-C510, with an anti-fingerprint, dustproof surface treatment.
• WUNIAK Case — biggest trade-off: it is listed as not water resistant, so rain and heavy sweat are a real concern, and the bundle only matters if you actually want the extras.
• Who each pick is for: TSVSXS for Bose Ultra Open owners who want personality plus water protection; WUNIAK for Sony WF-C510 owners who want a practical, hang-it-anywhere kit.
This one is built around a single job: wrapping your Bose Ultra Open Earbuds (2024) charging case in soft, flexible silicone and keeping every port and indicator usable. The listing is explicit that it is only compatible with that model, and the fit is described as snug without being overly tight — which matters with a hard-shell rival, because a case that grips too hard is a case you stop using.
The design is the headline. It is a game-console theme with raised and recessed button shapes, so the case reads as a small handheld console rather than a plain black pod. If you like your accessories to start conversations, that is the point. There is also a keychain in the box, plus an anti-lost ring, so you can clip it to a bag, belt or backpack instead of hunting for it at the bottom of a pocket.
Functionally, the details are the ones that actually matter day to day. The silicone is described as waterproof, sweat-proof, scratch-proof and durable, and it is washable, so it wipes clean instead of absorbing grime. You can charge with a cable without pulling the cover off, the charging port stays accessible, and the LED light remains visible while charging. The headphone logo showing through is a small touch, but it keeps the case looking intentional.
Who should buy it: Bose Ultra Open (2024) owners who want drop, bump and scratch protection with a bit of fun, and who value a waterproof, washable shell. Who should skip it: anyone with different earbuds — this will not fit — or anyone who wants a plain, discreet case. The item is listed at 1.12 ounces and roughly 1.05 x 1.65 x 2.56 inches, so it is small and light in a pocket or on a strap. If cost is your deciding factor, check the current price on Amazon before you commit.
The WUNIAK Case is a soft silicone cover made for the Sony WF-C510 truly wireless in-ear headphones, and the brand is upfront that it is not for other models. That single-model focus is the same approach as TSVSXS, just aimed at a different pair of earbuds — so the first question is simply which earbuds you own.
Where this one pulls ahead is the kit. The box includes the silicone case, a metal carabiner clip, a cleaning pen and a lanyard. That combination covers three everyday annoyances at once: losing the case (clip it to a backpack, belt loop or keychain), dirty earbuds (the cleaning pen), and carrying it hands-free (the lanyard). The carabiner is metal rather than plastic, which is the part most likely to fail on cheaper clips.
The material story is also more specific than most. It is soft, durable, elastic silicone with protection against scratches, bumps, shock and slipping, and the surface gets a special oil-spray treatment for anti-fingerprint and dustproof performance. In practice that means fewer smudges and less lint clinging to the shell — a real difference if your case lives in a pocket or gym bag. Installation is helped by a highly sticky double-sided adhesive design that holds the earbuds in place when you head out the door, and you can charge with a cable without removing the cover.
The honest trade-off: WUNIAK lists this case as not water resistant. Silicone will shrug off a splash and it wipes clean easily, but this is not the pick to trust in steady rain or a soaked gym bag. It is also a black, nature-patterned cover — practical and understated rather than playful.
Who should buy it: Sony WF-C510 owners who want a bundled, hang-anywhere protective kit with a cleaning pen and a metal clip. Who should skip it: anyone who needs genuine water resistance, or who owns anything other than the WF-C510.
• Best for water resistance → TSVSXS Silicone Case Compatible. It is listed as waterproof and washable; WUNIAK is listed as not water resistant.
• Best for earbud compatibility with Bose Ultra Open (2024) → TSVSXS Silicone Case Compatible. It is designed only for that model.
• Best for earbud compatibility with Sony WF-C510 → WUNIAK Case. Also single-model, also not interchangeable.
• Best bundled accessories → WUNIAK Case. Case, carabiner, cleaning pen and lanyard versus case plus keychain.
• Best for hanging on a backpack or belt → WUNIAK Case. The metal carabiner is the more secure clip of the two.
• Best for a distinctive, fun look → TSVSXS Silicone Case Compatible. The game-console design and see-through logo are the whole point.
• Best for keeping earbuds put when you grab and go → WUNIAK Case. Its sticky double-sided adhesive is designed for exactly that.
• Best for charging without removing the cover → a tie. Both support cable charging with the shell on, and both keep the charging port accessible.
In my opinion, the deciding factor here is your earbuds, not the case — these two are not interchangeable. If you own the Bose Ultra Open (2024), I would buy the TSVSXS Silicone Case Compatible: the waterproof, washable silicone and the snug fit are the things that keep a case in daily use, and the game design is a bonus rather than the reason. If you own the Sony WF-C510, I would buy the WUNIAK Case, because the carabiner, cleaning pen and lanyard make it the more complete everyday kit — as long as you accept that it is not water resistant. Pick the one that matches your earbuds, then check the current price on Amazon.
how to charge earbuds case
Put the earbuds back in the case first, then connect the charging cable to the port. Both the TSVSXS Silicone Case Compatible and the WUNIAK Case are designed so you can charge with the cover still on — no need to peel the silicone off. On the TSVSXS, the LED indicator stays visible while charging so you can see the status at a glance.
how to charge case without earbuds
You can plug the charging case in on its own — the earbuds do not need to be inside for the case to take a charge. With either cover fitted, the charging port stays accessible, so you just connect the cable as usual. The WUNIAK Case's sticky adhesive is there to keep the earbuds seated when they are in the case, not as a requirement for charging.
how to charge jlab earbuds case
Neither of these covers is made for JLab models. The TSVSXS Silicone Case Compatible fits only the Bose Ultra Open Earbuds (2024), and the WUNIAK Case fits only the Sony WF-C510. For JLab, you would want a case designed for that specific charging case, since the fit is model-specific.
how to charge apple earbuds case
Same answer: these two are not compatible with Apple earbuds. TSVSXS is built for the Bose Ultra Open (2024) and WUNIAK for the Sony WF-C510, and each brand states it is not for other models. Charging an Apple case means using a cover made for that case — the port cutouts and fit differ too much to swap.
