These two aren't really competitors in the usual sense — they're built for completely different earbuds. But if you landed here, you're probably holding one of these two models and trying to decide whether the case in front of you is the right one. Let's sort that out quickly.
• UYRUREL Compatible strength: Clear TPU shell with precise cutouts that support both wired and wireless charging without removing the cover, plus a visible LED window.
• UYRUREL Compatible trade-off: It only fits the Sony Ambie AM-TW02 — nothing else, and the clear finish is more about protection than personality.
• FJIASTB Case strength: Soft, skin-friendly silicone with an integrated flip cover and a full carry kit (case, keychain, wrist strap).
• FJIASTB Case trade-off: It's locked to the Moondrop Pudding TWS, and the dark green color is a fixed choice rather than a clear, show-off-the-device look.
• Who should pick UYRUREL Compatible: Sony Ambie AM-TW02 owners who want a low-profile, see-through shield with hassle-free charging.
• Who should pick FJIASTB Case: Moondrop Pudding TWS owners who want a grippy silicone cover and a ready-to-clip carry setup.
The UYRUREL Compatible case is a purpose-built shell for the Sony Ambie AM-TW02 Open-Ear TWS Earbuds. That's the whole story, and it matters. This isn't a universal pouch that will "sort of" fit — it's molded specifically for that one model, and UYRUREL is upfront that it isn't compatible with other related devices. If your earbuds are the Ambie AM-TW02, you're the intended buyer. If they aren't, walk away; no amount of stretching will make this right.
What you get is a clear Thermoplastic Polyurethane (TPU) enclosure with a slim-fit, soft-shell build. TPU is the interesting choice here. It's the material that tends to resist deformation, shrug off fingerprints, and cut down on static, dirt, and dust pickup — which is exactly what you want from a case that lives in a pocket or bag all day. The "nature" pattern styling is subtle, and because the material is clear, your actual earbuds case shows through rather than disappearing behind a solid color.
Charging is where this case earns its keep. The cutouts are precise enough that you can charge wired or wirelessly without pulling the cover off, and the LED indicator stays visible through the shell so you're not guessing whether the buds are topping up. That combination — charge in place, see the light — is the everyday difference between a case you tolerate and one you forget you're using.
FJIASTB Case: Who It's For
The FJIASTB Case is made for the Moondrop Pudding TWS earbuds and, like the UYRUREL option, it's a strict one-model fit. FJIASTB explicitly warns that it isn't suitable for other models and asks you to check your device before buying. Take that seriously — a silicone cover that's molded for one charging case won't do you any favors on another.
The material story here is soft silicone, which FJIASTB describes as skin-friendly and harmless, waterproof, and shockproof. That's a meaningfully different feel from TPU. Silicone tends to be grippier and softer to the touch, which helps it stay put in a hand or pocket and gives it a slightly cushioned feel against drops. The trade-off is that silicone loves to collect lint, so a dark green cover will show fuzz and dust more readily than you'd like.
The design detail I'd point to is the integrated build. FJIASTB notes the flip cover is integrated so it won't accidentally fall off. If you've ever owned a two-piece case that separated at the wrong moment, you know why that matters — it's the kind of small engineering decision that prevents the case from becoming a nuisance.
Charging is handled the same way as the UYRUREL: the case is designed so you can charge without disassembling anything. And the package is where FJIASTB pulls ahead on accessories. You get the case, a keychain, and a wrist strap — three carry options right out of the box, versus the UYRUREL's single lanyard. For someone who clips a case to a backpack strap or wants a wrist loop for walks, that's a real convenience advantage.
The color is dark green, and that's your only choice — there's no clear version that lets the Moondrop Pudding case show through. If you'd rather your earbuds case stayed visible, this isn't the pick. If you want a soft, grippy, fully kitted cover that travels well, it is.
Side-by-Side: Which Should You Choose?
• Best for Moondrop Pudding TWS owners → FJIASTB Case. Same rule, opposite device.
• Best for keeping your device visible → UYRUREL Compatible. The clear TPU shell lets the earbuds case and LED show through.
• Best for grip and a soft, cushioned feel → FJIASTB Case. Silicone is the grippier, more skin-friendly material of the two.
• Best carry kit out of the box → FJIASTB Case. Case, keychain, and wrist strap versus a single lanyard.
• Best for lint-free, low-maintenance looks → UYRUREL Compatible. Clear TPU resists fingerprints and dust better than dark silicone.
• Best for wireless charging without removing the case → both. Each uses precise cutouts that let you charge in place with the LED visible.
• Best for a flip cover that won't detach → FJIASTB Case. Its integrated design specifically targets that failure point.
The honest takeaway: this isn't a "which is better" question so much as a "which earbuds do you own" question. Match the case to your model first, then let material and accessories decide the rest.
In my opinion, the right buy comes down to your earbuds, not the case. If you own the Sony Ambie AM-TW02, I'd choose UYRUREL Compatible — the clear TPU build, precise charging cutouts, and visible LED make it the cleaner everyday companion. If you own the Moondrop Pudding TWS, I'd choose FJIASTB Case for its soft silicone grip, integrated flip cover, and the included keychain and wrist strap. Buy the one that fits your model. Don't cross the streams — neither case works on the other device.
No. UYRUREL states it's made only for the Sony Ambie AM-TW02 and isn't compatible with other related devices. If your earbuds aren't that model, this case won't fit properly.
Yes — it's designed specifically for the Moondrop Pudding TWS. FJIASTB cautions that it isn't suitable for other models, so double-check your device before ordering.
Yes. Both cases use cutouts that let you charge without removing the cover — UYRUREL supports wired and wireless charging with a visible LED, and FJIASTB is designed to charge without disassembly.
UYRUREL uses clear Thermoplastic Polyurethane (TPU) that resists fingerprints, static, dirt, and dust, while FJIASTB uses soft silicone that's described as skin-friendly, waterproof, and shockproof. In short: TPU for a clear, low-maintenance shell; silicone for a grippier, cushioned feel.
FJIASTB includes the case, a keychain, and a wrist strap. UYRUREL includes the case plus a lanyard. If carry options matter to you, FJIASTB gives you more to start with.
