• Bose Open Earbuds — biggest strength: Does two jobs at once. It adds wireless charging to your Bose Ultra Open Earbuds case and wraps the case in protective silicone, so you get power and protection in one piece.
• Bose Open Earbuds — biggest trade-off: It only fits one model — the Bose Ultra Open Earbuds. If that isn't your earbuds, this cover is useless to you.
• FJIASTB Case — biggest strength: Soft, skin-friendly silicone with a shockproof, waterproof shell and an integrated flip cover that won't pop off — plus charging without removing the case.
• FJIASTB Case — biggest trade-off: It's built specifically for the Bose QuietComfort Ultra Earbuds II (2nd Gen, 2025), and it's a protective cover only — no wireless charging upgrade.
• Who each is for: Bose Open Earbuds for Ultra Open owners who want wireless charging and a carabiner clip. FJIASTB Case for QuietComfort Ultra II owners who want cheap, soft, shockproof protection.
Let's be clear about what this product actually is, because the name can throw people off. The Bose Open Earbuds Wireless Charging Case Cover isn't a pair of earbuds — it's the case accessory for them. More specifically, it's a cover for the charging case, and the headline feature is right there in the name: it upgrades your case to wireless charging.
The construction backs that up. The enclosure is soft silicone, tinted White Smoke, and it's built to shield your case from outside scratches and scuffs. That matters more than it sounds. A charging case gets thrown in bags, dropped on desks, and shoved into pockets all day. A silicone skin absorbs that abuse instead of passing it along to the plastic underneath. Bose also rates the cover as water resistant, which is a sensible touch for something that lives in a gym bag or on a backpack.
Who should buy it? Someone who already owns Bose Ultra Open Earbuds and wants two upgrades at once — wireless charging and physical protection — without buying two separate accessories. Who should skip it? Anyone whose earbuds aren't the Bose Ultra Open Earbuds. Compatibility here is narrow and specific, and that's the whole ballgame.
FJIASTB Case: Who It's For
The FJIASTB Case takes a different approach. It's a soft silicone cover for the Bose QuietComfort Ultra Earbuds II (2nd Generation, 2025 release), finished in Dark Blue. The brand is upfront about the fit: it's compatible with that model and not suitable for other earbuds, and they ask you to check your model before buying. I'd take that warning seriously — a cover that doesn't match your case shape protects nothing.
What you get for that specificity is a genuinely thoughtful cover design. The silicone is described as skin-friendly and harmless, which matters because this is a material your hands touch constantly. It's also waterproof and shockproof, so a little rain or a drop onto a hard floor isn't the end of the world. The integrated design is my favorite part: the flip cover won't accidentally fall off. Anyone who's owned a hinged case cover knows the annoyance of a lid that flops open in your pocket — that's a real problem this design addresses.
Charging is handled sensibly too. The case is cut so you can charge without disassembling anything, meaning you don't have to peel the cover off every time you top up. The package includes the case, a carabiner, and a lanyard — a nice pair of carry options, whether you prefer clipping it to something or wearing it on your wrist. It's also built slim and travel-friendly.
Who should buy it? QuietComfort Ultra Earbuds II owners who want soft, shockproof, waterproof protection on a tight budget and don't need wireless charging added. Who should skip it? Owners of any other Bose model, and anyone specifically hunting for a wireless charging upgrade — that's not what this cover does.
• Best for wireless charging → Bose Open Earbuds. It's the entire point of the product: it upgrades your Bose Ultra Open Earbuds case to wireless charging.
• Best for drop and scratch protection → FJIASTB Case. Soft silicone, waterproof and shockproof, with an integrated flip cover that stays put.
• Best for charging without removing the cover → FJIASTB Case. Its design lets you charge with the cover still on. The Bose cover is built for wireless charging, so you're not wrestling with it either way.
• Best for carrying options → FJIASTB Case. You get both a carabiner and a lanyard. The Bose cover includes a carabiner only.
• Best for a slim, travel-friendly feel → FJIASTB Case. It's described as slim fit and travel compatible, and it's a straightforward protective skin.
• Best for a water-resistant cover with a manufacturer warranty → Bose Open Earbuds. Water resistant, and backed by a one-year manufacturer warranty.
• Best for Bose Ultra Open Earbuds owners → Bose Open Earbuds. Nothing else fits.
• Best for Bose QuietComfort Ultra Earbuds II owners → FJIASTB Case. Same logic, reversed.
In my opinion, the right pick comes down to one question: which Bose earbuds do you actually own? If you have the Bose Ultra Open Earbuds and you want wireless charging plus protection in a single accessory, I'd buy the Bose Open Earbuds cover — the wireless charging upgrade and the one-year warranty make it the more capable product. If you own the Bose QuietComfort Ultra Earbuds II and just want soft, shockproof, waterproof protection with a carabiner and a lanyard, I'd buy the FJIASTB Case. Neither is "better" in the abstract — they fit different earbuds, and that's the deciding factor.
how to charge earbuds case
The method depends on your case. With the Bose Open Earbuds cover, the case charges wirelessly — you set it on a wireless charging pad, no cable needed. With the FJIASTB Case, the cover is designed so you can charge without disassembly, meaning you don't have to remove the silicone to top up.
how to charge case without earbuds
Charging the case on its own is normal and fine. The case holds its own battery, so you can plug it in or set it on a wireless pad without the earbuds inside, then add the earbuds later. Just follow whatever charging method your specific case supports.
how to charge jlab earbuds case
That's a different brand entirely, and neither cover here is made for JLab. The Bose Open Earbuds cover fits only Bose Ultra Open Earbuds, and the FJIASTB Case fits only Bose QuietComfort Ultra Earbuds II. For JLab, you'd need a JLab-specific case and its own charging instructions.
how to charge apple earbuds case
Same answer, different brand. Apple earbuds cases use Apple's own charging setup, and neither of these Bose covers is compatible with them. Match the accessory to your exact earbuds model — that's the rule that keeps you from buying a cover that protects nothing.
