If you want a protective silicone case built specifically for Bose QuietComfort Earbuds II, Ultra and Ultra 2nd Gen — with a cleaning kit and a visible charging LED — choose Olytop Bose QuietComfort Earbuds; if you need a cute cartoon-style silicone cover with a carabiner for your AirPods 4, choose XMBYGY Cute Case.
• Olytop's biggest strength: a precision-molded, one-piece silicone shell made for Bose QuietComfort Earbuds II/Ultra charging cases, plus a 3-in-1 cleaning kit (flocking sponge, soft brush, metal pen tip) and a metal keychain.
• Olytop's biggest trade-off: it only fits Bose QuietComfort Earbuds II, Ultra and Ultra 2nd Gen — it is not water resistant, and the charging case itself is not included.
• XMBYGY's biggest strength: a soft silicone cartoon-pattern cover with a carabiner and a reserved charging port, so you can charge and open the lid without removing it.
• XMBYGY's biggest trade-off: it fits only AirPods 4 (2024) — not AirPods 1st/2nd/3rd Gen and not AirPods Pro or Pro 2 — and the earbuds are not included.
• Pick Olytop if you own Bose QuietComfort Earbuds II or Ultra and want drop protection plus a pocket-sized cleaning tool.
• Pick XMBYGY if you own AirPods 4 and want a fun, giftable cover you can clip to a bag.
Olytop's silicone case is a purpose-built cover for the Bose QuietComfort Earbuds II (2022), QuietComfort Ultra (2023) and Ultra 2nd Gen (2025) charging cases. The material is premium-grade silicone, precision molded for a snug fit, and it's a one-piece design — so there's no separate top cover to lose, which is a real annoyance with two-piece cases. The finish is described as silky and soft, and the case is built to absorb shocks and resist drops, scratches, scrapes and bumps. In the red colorway with a nature pattern, it's a practical, understated look rather than a novelty one.
What I like most here is the small stuff. The front LED stays visible while charging, and wireless charging works without pulling the case off — two things that sound minor until you're prying a silicone shell off every night. The included 3-in-1 cleaning kit (flocking sponge, soft brush, metal pen tip) is genuinely useful beyond earbuds: keyboard gaps, phone ports, camera seams. It weighs 0.4 oz and measures about 3.95 in long with a 0.53 in diameter, so it disappears in a bag. A metal keychain is included too.
Who should buy it: anyone who owns a Bose QuietComfort Earbuds II, Ultra or Ultra 2nd Gen charging case and wants everyday drop protection without blocking the LED or wireless charging, and who'd actually use a small cleaning tool. Who should skip it: AirPods owners (it won't fit at all), anyone who wants a waterproof cover — this one is listed as not water resistant — and anyone expecting the charging case in the box, because it isn't included. If you're weighing it up, check the current price on Amazon before deciding.
XMBYGY's case is a silicone cover made for AirPods 4 (2024) only. The compatibility note is worth repeating, because it's the single most common mistake with this product: it does not fit AirPods 1st or 2nd Gen (2016/2019), AirPods 3rd Gen (2021), AirPods Pro (2019) or AirPods Pro 2 (2022). If you own anything other than AirPods 4, this is not your case. The earbuds themselves are not included either — it's the cover only.
Where it shines is personality. The cartoon-pattern skin in the tomato-red colorway is designed to stand out, and the brand positions it as a gift for teens, men and women alike. It's made from soft silicone that the listing says won't scratch the charging station and won't loosen or deform over long-term use. A charging port is reserved at the bottom, so you charge without disassembling anything, and the cover is thin and light enough that you can open and close the lid by hand. Adsorption strength keeps it fastened firmly, and installation is straightforward.
The carabiner is the practical hook — clip it to a backpack strap, belt loop or keys, and your AirPods 4 stop living at the bottom of a bag. Who should buy it: AirPods 4 owners who want cute, colorful protection and a clip-on carry option, or anyone buying a small, inexpensive-feeling gift. Who should skip it: anyone with a different AirPods generation, and anyone who wants a cleaning tool or LED-visibility features — this one keeps things simple.
Side-by-Side: Which Should You Choose?
• Best for AirPods 4 owners → XMBYGY Cute Case. Olytop is Bose-only, so there's no crossover here.
• Best for charging convenience → Olytop. It keeps the front LED visible and supports wireless charging without removing the case.
• Best for style and gifting → XMBYGY. The cartoon skin and carabiner make it the more playful, gift-friendly pick.
• Best for keeping things clean → Olytop. The 3-in-1 cleaning kit works on earbuds, keyboards, phones and cameras; XMBYGY includes no cleaning tool.
• Best for clipping to a bag → XMBYGY. The carabiner is built for that; Olytop's metal keychain is more of a keys-and-lanyard accessory.
• Best for drop and scratch protection on Bose → Olytop. Shock-absorbing silicone with a snug, one-piece fit.
• Watch the fit: neither is water resistant, and neither includes the earbuds or charging case.
In my opinion, these two aren't really rivals — they're answers to different questions, and the question is which earbuds you own. If you have Bose QuietComfort Earbuds II, Ultra or Ultra 2nd Gen, I'd buy the Olytop: the one-piece fit, the visible LED, wireless-charging compatibility and the included cleaning kit make it the more useful everyday case. If you have AirPods 4 and want something cute that clips to your bag, I'd buy the XMBYGY. My overall pick goes to Olytop, simply because it does more per unit — protection plus a cleaning tool — for a Bose owner. Check the current price on Amazon for both before you commit.
Yes. It's designed for QuietComfort Earbuds II (2022), QuietComfort Ultra (2023) and Ultra 2nd Gen (2025) charging cases. It won't fit AirPods or other brands.
No. It's made only for AirPods 4 (2024). It does not fit AirPods 1st/2nd Gen, AirPods 3rd Gen, AirPods Pro or AirPods Pro 2 — double-check your model before ordering.
With Olytop, yes — wireless charging works and the front LED stays visible. With XMBYGY, yes — there's a reserved charging port at the bottom, so you charge without taking the cover off.
No. Both are covers only. Olytop includes the silicone case, a cleaning tool and a metal keychain; XMBYGY includes the silicone case and a carabiner.
