If you want a replacement charging case that keeps a pair of AirPods Pro 3rd Generation earbuds alive after the original case is lost or damaged, choose korllo A3122; if you need a complete set of Bluetooth earbuds with their own charging case, long battery life and a sport-ready build, choose Ordtop Earbuds. These two look similar in a search results page — both are white, both involve a charging case, both sit in the "earbuds" aisle — but they solve completely different problems. One is a case without earbuds. The other is earbuds with a case. Getting that wrong is the single most common mistake buyers make here, so let's sort it out properly.
• korllo A3122 — biggest strength: it's a purpose-built replacement charging case for AirPods Pro 3rd Generation earbuds (models A3064/A3063, case model A3122), with both USB-C and Qi wireless charging plus over-charge, over-voltage, over-temperature and short-circuit protection.
• korllo A3122 — biggest trade-off: case only. No earbuds are included, and it will not work with AirPods Pro 1st or 2nd Gen, AirPods 3, AirPods 4 or any other model.
• Ordtop Earbuds — biggest strength: a full, self-contained kit — Bluetooth 5.4 earbuds, a charging case with dual LED power display, up to 40 hours of total playback and IP7 water resistance.
• Ordtop Earbuds — biggest trade-off: they're their own ecosystem. You're buying new earbuds, not reviving an existing pair, and the noise control is passive rather than active.
• Who korllo A3122 is for: someone who already owns AirPods Pro 3rd Gen earbuds and just needs the case back.
• Who Ordtop Earbuds is for: someone who wants a complete, affordable everyday and workout pair — case, cable, ear tips and all.
The korllo A3122 is a niche product, and it's honest about that. This is a replacement charging case for AirPods Pro 3rd Generation earbuds — the ones carrying model numbers A3064 and A3063 — and it's built to match the A3122 case model. If your original case went through the washing machine, got crushed in a bag, or simply vanished on a train, this is the part that gets your existing earbuds charging again instead of forcing you to replace the whole set.
What it does best is the boring stuff that matters daily. You get two charging routes: a USB-C port for wired top-ups and Qi wireless charging if you'd rather drop it on a pad. Inside, korllo lists over-charge, over-voltage, over-temperature and short-circuit protection — the kind of safeguards that keep a battery from being stressed during regular overnight charging. Pairing is handled with a simple physical gesture rather than a menu: seat both earbuds, keep the lid open, double-tap the front of the case until the indicator flashes white, then pick your AirPods from the Bluetooth list. The shell is white ABS plastic, so it visually blends with the original hardware.
Buy it if you own AirPods Pro 3rd Gen earbuds and the case is the only thing that's broken or missing. Skip it if you don't already have those earbuds — this listing contains no earbuds at all, and it is explicitly not compatible with AirPods Pro 1st/2nd Gen, AirPods 3, AirPods 4 or other models. Check your model number before you order; that's the whole ballgame with this product.
The Ordtop Earbuds are the opposite proposition: a complete wireless earbud system that arrives ready to use. Inside the box you get two earbuds, the lightweight charging case, a USB-C cable and three sizes of ear caps (S/M/L). Nothing else to buy, nothing to match against existing hardware.
The headline spec is endurance. Ordtop rates a single charge at up to 8 hours of playback, with the case providing roughly four additional recharges for up to 40 hours of total music time. A dual LED display on the case shows the charge status of both the earbuds and the case itself, which is genuinely useful on a long trip — you can see what's left without guessing. The port is USB-C, which keeps charging quick and cable-common.
On the audio and connection side, they run Bluetooth 5.4 with support for HSP, HFP, A2DP and AVRCP, and Ordtop claims 0.1s low latency — worth noting if you watch video or play games and hate lip-sync drift. The driver is a 13mm dynamic unit paired with DSR lossless HD rendering, tuned for punchy bass and a full midrange. There are four HD mics with ENC noise cancelling for calls, so you should be intelligible on a video meeting or a call from a busy street, though note the noise control is listed as passive — this isn't active noise cancellation.
For sport, IP7 nano-coating protects the internals from sweat and splashes, and the curved, ear-canal-shaped design is meant to stay put while running or lifting. Touch sensors handle play/pause, track skipping, volume, calls and voice assistant activation. At 35 g for the set, they're light enough to forget you're wearing them.
Buy them if you want one purchase that covers commuting, gym sessions and calls, with battery life you won't have to think about. Skip them if you specifically need active noise cancellation or you're only looking to replace a case for earbuds you already own.
• Best for reviving existing AirPods Pro 3rd Gen earbuds → korllo A3122. It exists for exactly one job and does it.
• Best for a complete out-of-the-box setup → Ordtop Earbuds. Earbuds, case, cable and three ear tip sizes included.
• Best for battery life → Ordtop Earbuds. Up to 8 hours per charge and up to 40 hours total with the case.
• Best for charging flexibility → korllo A3122. Both USB-C wired and Qi wireless charging, which the Ordtop case doesn't list.
• Best for workouts and sweat → Ordtop Earbuds. IP7 water resistance and a shape designed to stay seated during runs.
• Best for calls in noisy places → Ordtop Earbuds. Four HD mics with ENC noise cancelling for voice pickup.
• Best for charging-status visibility → Ordtop Earbuds. The dual LED display shows both earbud and case power at a glance.
• Best for battery-safety features → korllo A3122. Over-charge, over-voltage, over-temperature and short-circuit protection are called out explicitly.
• Best for cross-platform use → Ordtop Earbuds. Works with iOS, Android, TV, laptop and other Bluetooth devices; the korllo case only fits specific AirPods Pro 3rd Gen models.
In my opinion, these aren't really competitors — they're two different purchases that happen to share a product category. If you own AirPods Pro 3rd Generation earbuds and your case is gone, I'd buy the korllo A3122 without hesitation; it's the cheaper path to a working pair again, it adds wireless charging and protection circuitry, and there's no reason to replace earbuds that still work. If you don't already own those earbuds, I'd buy the Ordtop Earbuds, because the korllo case is useless to you — no earbuds included, no compatibility outside that one model. Buy the korllo A3122 to fix something. Buy the Ordtop Earbuds to start something.
how to charge earbuds case
Drop the earbuds into the case and close the lid, then charge the case itself — either by plugging the case into a USB-C charger or, on models that support it like the korllo A3122, by placing it on a Qi wireless pad. The case's internal battery then recharges the earbuds. On the Ordtop Earbuds, the dual LED display shows the charge level of both the earbuds and the case so you know where things stand.
how to charge case without earbuds
You can charge either case on its own. The korllo A3122 accepts power over USB-C or Qi wireless even with no earbuds seated inside, and the Ordtop charging case likewise charges independently of the earbuds. Keeping the case topped up when empty is a reasonable habit before a trip, since the case is what refills the earbuds later.
how to charge jlab earbuds case
JLab cases aren't covered by either product on this page. The korllo A3122 is built specifically for AirPods Pro 3rd Generation earbuds (A3064/A3063, case model A3122), and the Ordtop case is designed only for Ordtop earbuds. For a JLab case, follow that brand's own instructions — usually a USB-C or micro-USB connection to the case.
how to charge apple earbuds case
Apple's own case charges over its standard connector or wirelessly depending on the model. If you're replacing a lost or damaged AirPods Pro 3rd Gen case, the korllo A3122 is the compatible option here: USB-C or Qi wireless charging, with over-charge, over-voltage, over-temperature and short-circuit protection built in. Remember the A3122 ships as a case only — your existing earbuds go inside it.
