We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a small, hard-shell pouch that carries earbuds and a few small extras without taking up space, choose MAS CARNEY Earphone Case Headphone; if you need a fitted, semi-hard organizer built specifically for the PocBuds Headphones 80hrs charging case — with a strap in the base and a mesh pocket in the lid — choose CaseSack PocBuds Headphones 80hrs.
• MAS CARNEY's biggest strength: a genuinely hard EVA shell in a tiny 3.15 x 3.15 x 1.18-inch footprint that weighs next to nothing, with a soft microfibre lining and a fully sealed zipper.
• MAS CARNEY's biggest trade-off: it's a general-purpose bag, not a fitted case — there's no strap or molded pocket to hold one specific device in place, and the stated maximum compatible device size is 7 cm.
• CaseSack's biggest strength: it's built around one device — the PocBuds Headphones 80hrs charging case — with an elastic strap to pin the device to the base and a mesh pocket in the lid for a cable and small accessories.
• CaseSack's biggest trade-off: it's bigger and bulkier, it only really makes sense if you own that specific PocBuds model, and the case is sold on its own with the device and accessories separate.
• Who each pick is for: MAS CARNEY for anyone who wants a compact, cheap-feeling-free hard pouch for earbuds plus odds and ends; CaseSack for a PocBuds 80hrs owner who wants a dedicated home for the charging case, cable and spares.
The MAS CARNEY case is the definition of small and simple. It measures roughly 3.15 x 3.15 x 1.18 inches and weighs about 17 g, so it disappears into a pocket, a purse or the corner of a backpack. The shell is hard EVA-based material with a polyurethane enclosure, and MAS CARNEY describes it as strong and compressive with rainwater protection — a hard outer layer plus water resistance, which is what you want if the case is going to rattle around loose in a bag.
Inside, the story is the microfibre lining. That soft inner surface is there to keep whatever you drop in from getting scratched, and the zipper is a fully sealed design that keeps dust out rather than just closing the opening. MAS CARNEY also mentions a built-in lattice package, which is a light internal divider arrangement for keeping small items apart instead of jumbled together. It's a "bag" form factor with a solid sport theme and a blue color, and it's marketed for headphones as the compatible device, with a maximum compatible device size of 7 cm.
So who should buy it? In my opinion, this is for the person who carries earbuds in a charging case plus a couple of small things — a charging cable, an adapter, a spare pair of tips — and wants one hard, light pouch to hold all of it. It's also a sensible pick if your earbuds case is on the smaller side, since 7 cm is the ceiling you're working with.
CaseSack PocBuds Headphones 80hrs: Who It's For
The CaseSack case exists for exactly one job: carrying the PocBuds Headphones 80hrs Playtime Charging Case Digital Display Sports Earbuds, plus the charger cable and small accessories that go with it. It's a semi-hard shell made with PEVA and ethylene vinyl acetate materials, described as absorbing pressure and hits and being water resistant. That "semi-hard" label matters — it's firmer than a fabric pouch but not a rigid box, which is a reasonable middle ground for something you toss into a shoulder bag or suitcase.
The design details are the real selling point here. There's an elastic secure strap in the base that holds the device in place, so the charging case doesn't slide around when you open the lid. And there's a mesh pocket in the lid for accessories — which is exactly where a short charging cable belongs, instead of tangling with the earbuds. CaseSack describes it as a strong, compact, lightweight all-in-one case that fits a purse, shoulder bag or suitcase, and it works for home storage as well as travel. It's black, solid-patterned, sport-themed, and it's compatible with PocBuds Headphones and iPhones as listed compatible phone models.
The size is where the trade-off lives. At 4.5 x 3.25 x 1.75 inches and about 1.8 ounces, it's noticeably bigger than the MAS CARNEY pouch — that extra room is what lets it swallow a cable and accessories, but it also means it takes up more space in a pocket. It is not a pocket case; it's a bag case.
Who should buy it? If you own the PocBuds 80hrs charging case and you're tired of it floating loose in a backpack with a cable wrapped around it, this is the obvious fit. Who should skip it? Anyone who doesn't own that specific PocBuds model, or who wants the smallest possible footprint. And note the fine print: only the protective case is included — the device and accessories are sold separately, so the case alone won't get you anything to charge. It also carries a 1-year warranty description, versus the Amazon Standard Warranty on the MAS CARNEY.
Side-by-Side: Which Should You Choose?
• Best for a hard, rigid shell → MAS CARNEY Earphone Case Headphone. It's described as a hard case with a hard shell type, while the CaseSack is semi-hard.
• Best for cable and accessory storage → CaseSack PocBuds Headphones 80hrs. The mesh pocket in the lid is made for exactly that; the MAS CARNEY relies on a lattice divider for small items.
• Best for pocket-sized portability → MAS CARNEY Earphone Case Headphone. At about 17 g and roughly 3.15 x 3.15 x 1.18 inches, it's the smaller, lighter option by a wide margin.
• Best for PocBuds 80hrs owners → CaseSack PocBuds Headphones 80hrs. It's compatibility-matched to that exact charging case, which the MAS CARNEY is not.
• Best for general earbuds and small items → MAS CARNEY Earphone Case Headphone. Its 7 cm maximum compatible device size and multifunctional bag design suit a range of small gear.
• Best for scratch protection on the inside → MAS CARNEY Earphone Case Headphone. The soft microfibre lining is explicitly there to protect devices from the inside.
• Warranty coverage → CaseSack PocBuds Headphones 80hrs lists a 1-year warranty description; the MAS CARNEY carries the Amazon Standard Warranty.
In my opinion, the right pick comes down to whether you own the PocBuds Headphones 80hrs charging case. If you do, I'd buy the CaseSack PocBuds Headphones 80hrs — the elastic strap and lid mesh pocket turn a loose charging case and cable into one organized, semi-hard bundle, and that's worth the extra bulk. If you don't own that specific model, or you just want the smallest hard pouch you can drop in a pocket, I'd take the MAS CARNEY Earphone Case Headphone instead. Its hard shell, microfibre lining and sealed zipper cover the basics in a fraction of the footprint.
how to charge earbuds case
The charging case itself charges from a cable — typically USB — plugged into the case's charging port, and the earbuds then charge from the case's internal battery when you drop them back in. Neither the MAS CARNEY pouch nor the CaseSack case charges anything; they're protective cases only, so you still charge the device itself the normal way. The CaseSack's mesh pocket is a handy place to keep that charging cable with the earbuds.
how to charge case without earbuds
You can charge a charging case with the earbuds removed — the case has its own battery, and it charges from its port whether or not the buds are inside. The only thing you're deciding is whether the buds top up at the same time. Either way, keep the case itself in something protective; the CaseSack's elastic strap holds the PocBuds charging case in place while it's stored or charging.
how to charge jlab earbuds case
JLab cases charge the same way as most others: connect the case's charging port to a power source with its cable and let the case's battery fill. If you're carrying a JLab-size case rather than a PocBuds one, the MAS CARNEY Earphone Case Headphone is the more general fit, since it isn't tied to a single model and accepts devices up to about 7 cm.
how to charge apple earbuds case
Apple's earbud cases charge by cable, and some also accept wireless charging — the case's own battery then recharges the buds. If you're looking for a carry case for one, the MAS CARNEY pouch is the flexible choice because it isn't built around one brand, while the CaseSack is specifically matched to the PocBuds Headphones 80hrs charging case. Both are storage and protection only — neither one charges your earbuds.
