How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a protective, wireless-charging upgrade for your Bose Ultra Open Earbuds, choose Bose Open Earbuds; if you need a full replacement charging case for your AirPods Pro 3, choose Baiyx Replacement Charging Case. These two products share the word "case," but they solve completely different problems for two different sets of earbuds — and buying the wrong one is a waste of your time.
• Bose Open Earbuds — biggest strength: It adds wireless charging and a clip-on carabiner to the Bose Ultra Open Earbuds case you already own, wrapped in soft, scratch-resistant silicone.
• Bose Open Earbuds — biggest trade-off: It is a protective cover, not a charger in itself, so it only makes sense if you already own the Bose Ultra Open Earbuds and their original case.
• Baiyx Replacement Charging Case — biggest strength: It is a complete, functional charging case for AirPods Pro 3, with a pairing button, LED power indicator, and enough capacity for several full recharges.
• Baiyx Replacement Charging Case — biggest trade-off: It is locked to one exact model (AirPods Pro 3, A3065/A3063/A3064) and will not work with any other AirPods generation.
• Pick Bose Open Earbuds if you want to protect and wirelessly charge earbuds you already have. Pick Baiyx if your AirPods Pro 3 case is lost or broken and you need a working replacement.
The Bose Ultra Open Earbuds Wireless Charging Case Cover is an accessory, and it's worth being clear about that up front. It does not replace your charging case — it wraps around the one that came with your Bose Ultra Open Earbuds. What it adds is convenience and defense. The soft silicone shell is built to absorb the everyday abuse a case takes: scratches, scuffs, and the general wear of being tossed in a bag or clipped to a belt loop.
Who should buy it? Bose Ultra Open Earbuds owners who charge wirelessly and want a grippier, softer, more protective exterior — especially people who carry their earbuds on the move. Who should skip it? Anyone who doesn't own the Bose Ultra Open Earbuds, since this cover fits nothing else. Also skip it if you want a hard shell: this is soft silicone, and Bose lists the water resistance level as not water resistant, so it's protection against bumps and scratches, not rain or sweat. It comes with the case cover, a carabiner, and a user manual, and it's backed by a one-year manufacturer warranty.
Baiyx Replacement Charging Case: Who It's For
The Baiyx Replacement Charging Case is a different animal entirely. This is a full, working charging case — not a cover — designed as a drop-in replacement for the AirPods Pro 3 generation. If your original case is lost, damaged, or simply won't hold a charge anymore, this is the kind of product that gets your earbuds back in rotation instead of leaving them stranded in a drawer.
The feature list is practical. There's a one-tap Bluetooth pairing button that syncs the case with your existing earbuds in seconds, so you're not fighting a pairing process. There's an LED indicator that shows the current power level at a glance — small thing, but you'll appreciate it daily. On capacity, Baiyx claims the case fully charges the earbuds in about 30 minutes and itself in roughly 2 hours, and provides up to 3 full charge cycles (the description elsewhere mentions 3 to 5 recharges), which is the difference between a weekend trip and a paperweight.
The housing is hard ABS plastic, which Baiyx describes as odorless, scratch-resistant, shockproof, non-slip, and durable — a reasonable match for something that lives in a pocket or bag. It supports both wireless and wired (USB-C) charging. Safety circuitry guards against over-charging, over-heating, short-circuits, overvoltage, overcurrent, and overload. The catch is compatibility, and it's a big one: this case works only with AirPods Pro 3 (Model A3065/A3063/A3064) and is explicitly not compatible with AirPods 1, 2, 3, or 4, nor Pro 1 or Pro 2. Check your model number before buying. Earbuds are not included, and the warranty runs 180 days.
• Best for protecting earbuds you already own → Bose Open Earbuds. It's a silicone cover, not a charger.
• Best for replacing a lost or dead case → Baiyx Replacement Charging Case. It's a functional charging case with real capacity.
• Best for wireless charging convenience → Bose Open Earbuds for the Bose Ultra Open Earbuds, and Baiyx for AirPods Pro 3 — both support wireless charging.
• Best for carrying on the go → Bose Open Earbuds, thanks to the built-in carabiner you can clip to a bag or strap.
• Best for a hard, shockproof shell → Baiyx Replacement Charging Case, which uses rigid ABS rather than soft silicone.
• Best for charging speed and backup power → Baiyx Replacement Charging Case, with its 30-minute earbud charge and multiple full recharge cycles.
• Best for a safe, protected charge → Baiyx Replacement Charging Case, which lists over-charge, over-heat, and short-circuit protection.
• Best for broad compatibility → neither. Each is locked to a specific earbud model; Bose fits only the Ultra Open Earbuds, and Baiyx fits only AirPods Pro 3.
In my opinion, the right pick comes down entirely to which earbuds are in your pocket. If you own the Bose Ultra Open Earbuds and just want a softer, grippier, wireless-charging-friendly cover you can clip anywhere, I'd buy the Bose Open Earbuds. If your AirPods Pro 3 case is lost or failing, I'd buy the Baiyx Replacement Charging Case — it's the one that actually restores function rather than decorating it. Just confirm your exact model first, because neither product forgives a wrong guess. If price matters to you, check the current price on Amazon before deciding.
It's a full replacement charging case, not a cover. It charges your AirPods Pro 3 earbuds, pairs via a Bluetooth button, and has an LED power indicator.
No. It's made specifically for the Bose Ultra Open Earbuds and fits nothing else. For AirPods Pro 3, you'd want the Baiyx case instead.
No. Baiyx states it is compatible only with AirPods Pro 3 (A3065/A3063/A3064) and not with AirPods 1, 2, 3, 4, or Pro 1 and Pro 2. Check your model number before ordering.
No. The Baiyx case explicitly does not include earbuds, and the Bose cover is an accessory for earbuds you already own.
