• korllo's biggest strength: it's a genuine, pre-owned charging case for the Galaxy Buds 3 Pro that supports both USB-C wired charging and wireless charging — a real power source for earbuds whose original case is lost or dead.
• korllo's biggest trade-off: it's used, it's case-only, and it only fits the Buds 3 Pro SM-R630 — not the standard Galaxy Buds 3.
• HAOBOBRO's biggest strength: a rigid polycarbonate shell wrapped in woolen-textured vegan leather, with adhesive strips and a removal tool, so it protects a Bose charging case without loosening over time.
• HAOBOBRO's biggest trade-off: it's a protective outer case, not a charger. It adds weight and bulk and does nothing about battery life.
• Choose korllo if you already own Buds 3 Pro earbuds and need to charge them again.
• Choose HAOBOBRO if you already own Bose QC Ultra or QC Earbuds II and want to protect the case you have.
The korllo case solves one very specific problem: your Galaxy Buds 3 Pro earbuds are fine, but the case that charges them isn't. It's a genuine replacement charging box for the SM-R630 model, and it's listed as pre-owned but tested and working. In other words, someone else's original case, checked over and ready to pair with your earbuds.
What it does best is restore function. You drop the earbuds in, hold the pairing button on the bottom for roughly three seconds until the light flashes, and select the buds from your phone's Bluetooth list. From there you can top up over USB-C or set the whole thing on a wireless pad — which matters if your desk or nightstand already has a charging surface and you'd rather not hunt for a cable. For anyone who streams music or podcasts for hours — the kind of listener who treats earbuds as an always-on companion — a working case is the difference between earbuds that last the day and earbuds that sit in a drawer.
Who should buy it: Galaxy Buds 3 Pro owners with a lost, damaged, or non-charging original case who want an authentic replacement with a one-year warranty behind it. Who should skip it: anyone with the standard Galaxy Buds 3 (it won't fit), and anyone expecting earbuds in the box — this is case only. Also skip it if your priority is cosmetics; this is a plain silver functional shell, not a style piece.
HAOBOBRO's case is the opposite kind of product: it doesn't power anything, it protects. It's built for Bose QuietComfort Ultra Earbuds (1st and 2nd Gen) and QuietComfort Earbuds II, and its whole pitch is materials and construction. The exterior is fully covered in PU leather treated to feel like woolen cloth — a skin-friendly texture rather than slick plastic. Underneath sits a rigid, injection-molded polycarbonate shell, and inside there's a recycled microfiber lining to cushion whatever it's wrapped around.
The details show the intent. Adhesive strips lock the shell to the charging case so the lid doesn't slide off, and a T-shaped removal tool is included so you can take it off again without prying at it. The maker claims the hard shell won't loosen over time the way some soft cases do — which is the real test for any snap-on cover. At 36.5 grams and roughly 2.95 x 2.6 x 1.26 inches, it's a compact, pocketable layer, not a bulky armor box.
Who should buy it: Bose QC Ultra or QC Earbuds II owners who carry their case loose in a bag, clip it to a strap, or work somewhere that's hard on gear — a jobsite, a commute, a crowded office — and want it to look good doing it. Who should skip it: anyone who doesn't own a compatible Bose model, and anyone hoping this replaces a charging case. It's a cover, not a charger.
• Best for restoring power to lost-case earbuds → korllo Replacement Charging Case. It's an actual charging case with wired and wireless options.
• Best for protecting a working Bose case → HAOBOBRO Handmade Case. Rigid shell, adhesive fit, microfiber lining.
• Best for wireless-charging convenience → korllo. It supports cable-free top-ups; HAOBOBRO is protection only.
• Best for build quality and feel → HAOBOBRO. Vegan leather over polycarbonate is a genuinely nicer object in hand than a plain plastic charging box.
• Best for kids headphones for streaming setups at home → it depends on the earbuds you own. korllo only fits Buds 3 Pro; HAOBOBRO only fits the three Bose models listed.
• Best for long listening sessions → korllo, because a charged case is what keeps earbuds alive through the day.
• Best for durability against scrapes and drops → HAOBOBRO. Its shock-absorbing shell is designed for exactly that.
• Best for a no-fuss, single-purpose buy → korllo if you need charging, HAOBOBRO if you need protection.
One more angle worth naming: if you're shopping for bluetooth headphones for streaming and you already own one of these two earbud families, the "right" accessory is simply the one that matches your model. The korllo case is useless to a Bose owner, and the HAOBOBRO shell is useless to a Samsung owner. Match the model first, then decide whether you need power or protection.
In my opinion, the korllo Replacement Charging Case is the pick for most people who land on this comparison, because it fixes a problem that actually stops you using your earbuds — no charge, no streaming. It's the practical choice for Galaxy Buds 3 Pro owners who lost or broke their original case and just want their earbuds working again, with both wired and wireless charging and a one-year warranty as backup. I'd choose HAOBOBRO only if my Bose case already works and I want it to stay pristine — it's the better-looking, better-built object, but it can't charge anything. Buy the one that matches your earbuds and your actual need. If price matters to you, check the current price on Amazon before deciding.
how to charge earbuds case
For the korllo case, place the Galaxy Buds 3 Pro earbuds inside, then charge the case itself either over USB-C or on a wireless charging pad. The case stores power and passes it to the earbuds. The HAOBOBRO case does not charge anything — it's a protective cover that stays on your existing Bose charging case.
how to charge case without earbuds
You can charge the korllo case on its own — plug in USB-C or set it on a wireless pad with the earbuds removed, and it will hold that power for later. Just remember the earbuds themselves only charge once they're seated inside the case. With HAOBOBRO, there's no charging function at all; you charge the Bose case underneath it as usual.
how to charge jlab earbuds case
Neither product here is made for JLab. The korllo case is designed specifically for the Samsung Galaxy Buds 3 Pro SM-R630, and the HAOBOBRO case fits Bose QuietComfort Ultra Earbuds (1st and 2nd Gen) and QuietComfort Earbuds II. Check your own model number before buying either one.

Same answer: these aren't AirPods accessories. korllo only fits the Galaxy Buds 3 Pro, and HAOBOBRO only fits the listed Bose models. If you're on AirPods, neither of these will work — you'd need a case built for your specific model.
