If you want a rugged, travel-ready hard shell that protects a pair of foldable on-ear headphones you already own, choose Comecase Headphone Case; if you need an affordable wired on-ear headphone with a mic and a sharing jack for everyday listening, choose JOMILIN A10.
• Comecase Headphone Case — biggest trade-off: it's a case only. No headphones included, so it's useless unless you already own a compatible foldable pair.
• JOMILIN A10 — biggest strength: a complete wired on-ear headphone with a 40 mm driver, in-line mic, tangle-free 1.5 m cord and a sharing jack for splitting audio with someone nearby.
• JOMILIN A10 — biggest trade-off: it's wired and its folding design makes it portable, but it doesn't ship with the kind of rigid protective shell the Comecase provides.
• Who each pick is for: Comecase is for the owner of a foldable on-ear headphone who wants to carry it safely; JOMILIN A10 is for the listener who needs a working headphone right out of the box.
The Comecase case is a storage and transport product, not a listening one. Its whole job is to hold a compatible foldable on-ear headphone — the data sheet lists Beats Solo2, Solo3, Solo4, Studio3 and Studio Pro, plus JBL E45BT and E55BT, Sony MDR-ZX110, TOZO HT2, noot products K11 and a long list of other foldable Bluetooth over-ear and on-ear models. If your headphones fold, there's a good chance this shell was shaped with something like them in mind.
What it does best is protection. The enclosure is a hard shell made from ethylene vinyl acetate, wrapped in PU leather, and Comecase describes it as semi-waterproof, shockproof and resistant to dust, scratches, scuffs, crush and moisture. In everyday terms: it's the thing that stops your folded headphones from getting squashed at the bottom of a backpack or rattling around loose in a carry-on. The interior mesh pocket takes a charging cable or a small adapter, the removable hand strap makes it easy to carry on its own, and the carabiner lets you clip it to a bag strap.
Who should buy it: anyone who already owns one of the listed foldable headphones and treats it as a real piece of gear rather than something to toss in a drawer. The 6.1 x 3.35 x 7.87 inch dimensions and "extra large" framing suggest it's sized for full-size foldable cans rather than tiny earbuds. It's also worth noting it comes with an 18-month warranty description.
JOMILIN A10: Who It's For
The JOMILIN A10 is the opposite kind of purchase: a finished, ready-to-listen on-ear headphone. It's wired, with a 3.5 mm jack and a 1.5 m no-tangle cord, and it works with phones, tablets, computers, laptops, MP3 and MP4 players and anything else with a standard 3.5 mm audio jack. There's a friendly in-line remote with a microphone for calls and track skipping, which is the sort of thing that matters more than people expect on a commute.
The sound side is built around a 40 mm dynamic driver with a 20 Hz – 20,000 Hz frequency range, and JOMILIN describes the tuning as full-range with rich bass and crisp mids. The earcups and headband are padded, and the adjustable slider is there so the fit isn't fixed — useful if you're sharing it or handing it to a kid. The green color and plastic build keep it light — it weighs about 0.24 kg — and the folding design is what makes it genuinely portable.
There's one feature that stands out for families and shared spaces: a sharing jack. A second person can plug their own headphones into the A10 and hear the same audio, no splitter needed. That's a small thing that makes long car rides and shared screens a lot easier.
Who should buy it: someone who wants one complete, inexpensive wired headphone for calls, schoolwork, travel and casual listening, and who values the mic and sharing jack. Who should skip it: anyone who wants a protective hard case included, or who needs wireless listening as the primary mode — the A10's core connection is the 3.5 mm cable. It also carries a 1-year warranty description.
Side-by-Side: Which Should You Choose?
• Best for protecting headphones you already own → Comecase Headphone Case. Hard shell, PU leather, shockproof and semi-waterproof.
• Best for getting a working headphone today → JOMILIN A10. Complete unit with cable, mic and drivers included.
• Best for calls and online classes → JOMILIN A10. In-line microphone and remote media controls.
• Best for sharing audio with a friend or sibling → JOMILIN A10. The sharing jack takes a second pair of headphones directly.
• Best for kids and teens → JOMILIN A10. Light plastic build, adjustable slider, padded cushions and a green finish aimed at younger listeners.
• Best for someone with a drawer full of foldable Beats, JBL or Sony on-ears → Comecase Headphone Case. It's built around those exact models.
• Best if you're not sure what you're buying → Comecase, but only if you own compatible headphones. Otherwise the A10 is the safer, self-contained pick.
These two products barely compete — they solve different problems. If I had to choose one for the average shopper reading this, I'd pick the JOMILIN A10, because it's a complete headphone you can use the moment it arrives: mic, sharing jack, padded on-ear fit, folding design. The Comecase Headphone Case is the better buy only in one specific situation — you already own a compatible foldable on-ear headphone and want to stop it getting crushed. In my opinion, if you're still deciding, ask yourself whether you need to listen or to protect. That single question settles it.
are on ear headphones good
Yes, for a lot of everyday situations. On-ear headphones like the JOMILIN A10 sit against the ear rather than around it, which keeps them lighter and more portable than over-ear models. The trade-off is usually less isolation and less long-session comfort, though the A10's padded cushions and adjustable slider are designed to reduce that fatigue.
what are the best open ear headphones
"Open ear" usually means a design that doesn't seal over or into the ear canal. Neither product here is an open-ear model — the JOMILIN A10 is a traditional wired on-ear headphone with 40 mm drivers, and the Comecase is a storage case, not a headphone at all. If open-ear is what you actually want, keep looking.
which are the best over the ear headphones
"Over ear" means the cups surround your ear, which generally gives better isolation than on-ear. The Comecase case is listed as compatible with several over-ear models, including Beats Studio3 and Studio Pro, so if you already own one of those, it's a sensible way to protect them. It does not include headphones, so it can't be the headphone itself.
what are the best over the ear headphones to buy
That depends on whether you want wired or wireless and how you'll use them. If you want a simple wired pair for calls, study and casual listening, the JOMILIN A10 covers that ground with a mic, a sharing jack and a folding frame. If you already own a foldable pair, the Comecase case is the accessory that keeps them intact. Compare the current prices on Amazon before deciding.
