How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a like-for-like replacement case for your Bose Ultra Open Earbuds with a simple USB-C top-up, choose Bose Open Earbuds Charging; if you need a Galaxy Buds3 Pro case that charges both wired and wirelessly and re-pairs your buds on open, choose Samsung Charging Case.
• Bose Open Earbuds Charging — biggest strength: it's the genuine Bose replacement/additional case for the Ultra Open Earbuds, in a hard plastic shell, and it charges over USB-C.
• Bose Open Earbuds Charging — biggest trade-off: it's a companion for one specific earbud model only, and it's listed as not water resistant.
• Samsung Charging Case — biggest strength: it handles both wired and wireless charging and pairs the Galaxy Buds3 Pro to your Galaxy device simply by opening the case.
• Samsung Charging Case — biggest trade-off: it's case-only, and it's built for one model — Galaxy Buds3 Pro.
• Pick Bose Open Earbuds Charging if you own Bose Ultra Open Earbuds and want the matching case in Black or White Smoke.
• Pick Samsung Charging Case if you own Galaxy Buds3 Pro and want a spare or replacement case with wireless charging.
This is the unglamorous but essential accessory: it's the Bose charging case for the Ultra Open Earbuds, sold as either a replacement if you've lost yours or a second case to keep somewhere else. That second-case idea is the real selling point for a lot of people. If you leave one case at your desk and one in your bag, you stop carrying the case back and forth — you just drop the buds into whichever one is nearby.
What it does best is fit and finish. It's hard plastic, it's solid, it's sized at roughly 1.04 x 2.56 x 1.65 inches and weighs 1.6 ounces, which makes it genuinely pocketable rather than a brick. It charges via USB-C, so it slots into the same cable you already use for most of your other gear. It's available in Black, which is the version I'm describing here, and also in White Smoke if you'd rather match a lighter setup.
Who should skip it: anyone who doesn't own Ultra Open Earbuds. It fits that model and that model only, so it's useless with any other earbuds. Also worth flagging — Bose lists the water resistance level as "Not Water Resistant." Treat this as a dry-bag item. Don't leave it in a gym bag next to a wet towel or in a rain-soaked jacket pocket and expect it to shrug it off.
Samsung Charging Case: Who It's For
This one is a straight replacement case for the Galaxy Buds3 Pro — and Samsung is unusually blunt about it: the earbuds are not included. You're buying the case, the USB-C cable, and the pairing behavior that comes with it.
That pairing behavior is the headline feature. Open the case and the Buds3 Pro pair to your Galaxy device; if you need to force a connection, you press and hold the button on the bottom of the case for about three seconds. For anyone who has fiddled with a stubborn Bluetooth menu mid-commute, that's the kind of small convenience that quietly matters every single day. It's also the reason a replacement case has to be the right case — the pairing handshake is part of the hardware, not something a third-party shell can fake.
The other differentiator is charging. This case accepts both wired charging via USB-C and wireless charging. Wireless matters more than it sounds: if you already drop your phone on a charging pad at night, adding the case to that same pad is one less cable in your life. It's polycarbonate, silver, lightweight at 47.06 grams, and compact at about 2.32 x 1.92 x 0.96 inches — slightly wider and flatter than the Bose case, but in the same pocketable class.
Who should buy it: Galaxy Buds3 Pro owners who lost or damaged their case, or who want a second one for the office, car, or travel bag. The 1-year manufacturer warranty applies too.
Who should skip it: anyone without Galaxy Buds3 Pro. And be honest with yourself about the "case only" part — if you're shopping because your buds themselves died, this purchase won't help you.
• Best for a matching first-party replacement → Bose Open Earbuds Charging. It's the Bose case made for the Bose Ultra Open Earbuds, down to the model number.
• Best for charging flexibility → Samsung Charging Case. It does wired and wireless; the Bose case is USB-C only.
• Best for fast re-pairing → Samsung Charging Case. Open the case and the Buds3 Pro connect; the three-second button press is there as a fallback.
• Best for color choice → Bose Open Earbuds Charging. It comes in Black or White Smoke. The Samsung case is Silver.
• Best for the lightest possible carry → Bose Open Earbuds Charging. At 1.6 ounces it's the lighter of the two; the Samsung case is 47.06 grams.
• Best if you're rough on gear or outdoors a lot → neither, strictly speaking. Bose lists its case as not water resistant, and Samsung doesn't list a water resistance rating for its case at all. Keep both dry.
• Best for a spare case you leave in one place → either, depending on your earbuds. This is the single most common reason people buy a second case, and both products are designed to serve it.
• Best for you, period → the one that matches your earbuds. Bose case for Ultra Open Earbuds; Samsung case for Galaxy Buds3 Pro. There's no crossover here, and that's the whole decision.
In my opinion, the choice is settled before you read a single spec: buy the case that matches the earbuds you already own. There is no universal option in this comparison, and that's a feature, not a flaw — the pairing and charging behavior of each case is tied to its own earbuds.
If I had to pick one for the way most people actually live, I'd lean toward the Samsung Charging Case (B0F6DVYNBX), because wireless charging plus open-and-pair is the more convenient daily routine. But if you own Bose Ultra Open Earbuds, the Bose case (B0CTMSVGXW) is the correct and only sensible buy — and the Black or White Smoke choice is a nice touch.
Yes, if you own Galaxy Buds3 Pro. A second case means you can leave one at home and one in your bag, and because pairing happens when the case opens, the swap is basically seamless. Just remember the earbuds aren't included — you're buying the case and a USB-C cable.
No. It fits Bose Ultra Open Earbuds specifically. It's a first-party Bose replacement or additional case, and it charges over USB-C. If you own a different model, this case won't help you, no matter how similar the shape looks in photos.
Both are compact and pocketable, so it comes down to your habits. The Bose case is lighter at 1.6 ounces, which suits minimalist packing. The Samsung case adds wireless charging, which means one less cable to pack if you already travel with a charging pad. Neither is listed as water resistant, so pack accordingly.
