If you want a complete, ready-to-use set of earbuds with a playful charging case built in, choose AMAFACE Tiny; if you need a protective silicone cover for the Bose QuietComfort Ultra Earbuds II you already own, choose FJIASTB Case.
• AMAFACE Tiny – biggest strength: It's a full earbud system, not an accessory. Bluetooth 5.3, CVC8.0 noise reduction, IPX5 waterproofing, touch controls and a cartoon charging case that pushes total playback to a claimed 35 hours.
• AMAFACE Tiny – biggest trade-off: The playful "LITTLE DEVIL" cartoon styling is a love-it-or-leave-it look, and this is clearly aimed at kids, casual listeners and gift buyers rather than critical listeners.
• FJIASTB Case – biggest strength: A soft, skin-friendly silicone shell with a carabiner and lanyard that protects your Bose QuietComfort Ultra Earbuds II from drops and scratches, and it charges without you taking it off.
• FJIASTB Case – biggest trade-off: It does absolutely nothing on its own. No earbuds, no sound, no battery. It only fits one specific model, and if you own anything else it's useless to you.
• Who AMAFACE Tiny is for: Anyone who wants working earbuds out of the box, especially parents buying for kids over three.
• Who FJIASTB Case is for: Someone who already owns the Bose QuietComfort Ultra Earbuds II and wants cheap insurance against dings and scuffs.
The AMAFACE Tiny is a self-contained package. You get the earbuds, the cartoon charging case, a USB Type-C cable, three sizes of earcips and a manual. The Bluetooth 5.3 chip with a Qualcomm component and CVC8.0 noise reduction is a sensible spec set for a budget-friendly daily pair, and the claimed 5-second pairing and one-tap "B29" connection on your phone keep setup simple. Battery is the headline: roughly 5 hours per charge, with the case adding around 30 more hours across three to five top-ups, plus a quick-charge claim of 20 minutes for 2 hours of talk time.
Buy it if you want a complete, giftable, kid-friendly set with a genuinely long total battery figure and a case that looks like a toy rather than a tool. Skip it if you care about neutral sound, premium materials or a discreet, adult aesthetic — and skip it if you already own Bose Ultra Earbuds II, because you don't need earbuds at all.
FJIASTB Case: Who It's For
This is a single-purpose product and it's honest about it. The FJIASTB Case is a soft silicone protective cover made specifically for the Bose QuietComfort Ultra Earbuds II (2nd Generation, 2025 release). The listing states plainly that it does not fit other models, so checking your earbuds model first is step one. If you're in, you get a dark blue, skin-friendly shell with a slim fit, an integrated flip-cover design that won't pop off by accident, and — the detail that actually matters day to day — charging without disassembly. You drop the case in place and top up, no peeling required.
It's waterproof and shockproof in the sense that silicone absorbs impact and shrugs off splashes, which is exactly what you want when the alternative is a bare Bose charging case rattling around a bag. The package includes the case, a carabiner and a lanyard, so you can clip it to a backpack strap or belt loop instead of hunting for it at the bottom of a pocket. FJIASTB also advertises 24-hour after-sales support if something goes wrong.
Buy it if you've got the Bose Ultra Earbuds II and want cheap, low-effort protection with a clip-on carry option. Skip it if you own any other earbuds, if you don't like silicone, or if you were hoping this listing included actual earbuds — it doesn't.
Side-by-Side: Which Should You Choose?
• Best for protecting gear you already own → FJIASTB Case. Pure silicone armor with a carabiner and lanyard.
• Best for kids and gifts → AMAFACE Tiny. The cartoon case, earcip sizes and holiday framing are built for it.
• Best for workouts and sweaty use → AMAFACE Tiny. IPX5 waterproofing on the buds themselves; the FJIASTB cover is splash-resistant but houses no electronics.
• Best for charging convenience → FJIASTB Case. Charge without taking the cover off, which is the one thing a case cover must get right.
• Best for sound quality → AMAFACE Tiny (by default). It's the only one of the two that makes sound at all.
• Best for minimal effort → AMAFACE Tiny. Open box, pair, listen. No model-matching homework required.
• Best for people who own Bose QuietComfort Ultra Earbuds II → FJIASTB Case. And only them.
If I had to pick one, I'd buy the AMAFACE Tiny — but only because most people searching "charging case earbuds" want earbuds, not an accessory. It's a complete, working system: buds, case, cable, earcips, long claimed battery and a look that kids actually ask for. In my opinion, the FJIASTB Case is the smarter buy for a narrower, more specific person: someone who already owns the Bose QuietComfort Ultra Earbuds II and wants to keep that charging case from getting beaten up for very little money. If that's you, buy the cover. If you don't own those Bose earbuds, it's the wrong product entirely. Either way, check the current price on Amazon before committing — the button on this page takes you there.
FAQ
You can charge an empty case, and in the AMAFACE Tiny's case that's the sensible move — topping up the box first means it's ready to refill the buds later. The FJIASTB cover doesn't hold power at all, so it plays no role here; you're just charging your Bose case through the silicone.
That's a different brand, and neither product on this page fits JLab gear — the FJIASTB Case is made only for the Bose QuietComfort Ultra Earbuds II, and the AMAFACE Tiny is a complete earbud set with its own case, not a universal cover. Check your specific JLab model's own instructions instead.
Same answer: neither the AMAFACE Tiny nor the FJIASTB Case is designed for Apple earbuds or their cases. The FJIASTB cover is model-specific to Bose, and the AMAFACE set charges only its own included buds via USB Type-C.
