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 hard-shell case for your foldable on-ear or over-ear Bluetooth headphones, choose Comecase Headphone Case; if you need a bulk set of eight wired kids' headphones for a classroom or a family with several children, choose Hengliyuan Kids Headphones Bulk.
These two products sit in completely different corners of the headphone world. One is a storage and travel accessory. The other is an eight-pack of actual headphones. The only reason they're compared at all is that both show up in the same shopping searches, so let's cut through it fast: you should pick based on whether you need protection or you need headphones.
• Comecase Headphone Case — biggest strength: A hard EVA shell with a PU leather cover that guards foldable on-ear and over-ear headphones from dust, scratches, shock, crush and moisture, with a hand strap, carabiner and inner mesh pocket for accessories.
• Comecase Headphone Case — biggest trade-off: It's a case only. No headphones are included, and it's built for full-size foldable models, not small kids' sets.
• Hengliyuan Kids Headphones Bulk — biggest strength: Eight individually wrapped wired headphones in eight different colors, with a reinforced 3.5 mm plug, retractable headband and swivel earcups — a ready-made class set in one box.
• Hengliyuan Kids Headphones Bulk — biggest trade-off: They're wired, plastic, on-ear headphones with sound isolation only. No hard case, no Bluetooth, no active noise cancellation.
• Who the Comecase case is for: Anyone who already owns a pair of foldable on-ear or over-ear headphones and wants to stop them getting crushed in a bag.
• Who the Hengliyuan set is for: Teachers, schools, and parents who need several pairs of cheap, durable, kid-friendly wired headphones at once.
The Comecase case is a storage and travel product, and it's honest about that. The listing says it plainly: for sale is case only, the headphone is not included. So the first thing to understand is that you're buying protection, not sound.
What it does well is protection. The enclosure is ethylene vinyl acetate — a hard shell — wrapped in quality PU leather, and Comecase describes it as semi-waterproof, shockproof and comfortable to the touch. In practice that means it resists dust, scratches, scuffs, shock, crush and moisture. The item measures 6.1 x 3.35 x 7.87 inches, so it's sized for full-size foldable headphones rather than earbuds. Inside there's a mesh pocket for cables and chargers, and outside there's a removable hand strap plus a carabiner for hanging it off a backpack. Comecase rates the water resistance level as waterproof and lists an 18-month warranty.
The compatibility list is specific and worth checking before you buy. Comecase names Beats Solo2, Solo3, Solo4, Studio3 and Studio Pro, the JBL E45BT and E55BT, Sony MDR-ZX110, TOZO HT2, the noot products K11, plus Picun P26, Mpow 059, Elecder i39 and others in the foldable on-ear and around-ear family. If your headphones fold and roughly match those dimensions, it should fit.
Who should buy it: someone who already owns one of those foldable pairs and travels, commutes, or just tosses their headphones in a backpack and is tired of scuffed earcups. Who should skip it: anyone who doesn't own headphones yet, anyone with a non-folding or unusually large model, and anyone expecting a case to come with anything to put in it. In my opinion this is a straightforward "buy if it fits your model" product — there's no hidden angle.
This is a totally different kind of purchase. The Hengliyuan set is eight headphones in one box, in eight colors: red, orange, yellow, light blue, dark blue, pink, white and black. Each one is individually wrapped and sealed, which matters if you're handing them out to students or splitting them between kids.
The build is aimed squarely at children and classrooms. The cable is 1.2 m (about 47.25 inches) of sturdy PVC — long enough that kids aren't yanking the plug out of a tablet. The 3.5 mm plug uses a special reinforcement process, and Hengliyuan says that extends usable life by at least 6 to 12 months. The headband is retractable to fit both adult and child head shapes, and the earcups swivel so they fold flat for storage. The ear cushions are soft sponge, and the housing is described as lightweight and adjustable for rugged durability. Hengliyuan backs the set with a 1-year warranty.
On the audio side you get 32 ohm impedance, a frequency response of 20.4 KHz and 92 dB sensitivity, with sound isolation rather than active noise cancellation. It's a wired 3.5 mm connection, so it works with iPads, tablets, smartphones and PCs — anything with a standard headphone jack.
Side-by-Side: Which Should You Choose?
• Best for protecting headphones you already own → Comecase Headphone Case. Hard EVA shell, PU leather cover, crush and moisture resistance.
• Best for getting headphones into kids' hands → Hengliyuan Kids Headphones Bulk. Eight pairs, eight colors, individually wrapped.
• Best for travel → Comecase Headphone Case. Lightweight and compact with a hand strap and carabiner for backpacks, carry-ons and luggage.
• Best for classroom or school use → Hengliyuan Kids Headphones Bulk. Reinforced 3.5 mm plugs and a 1.2 m cable designed for students.
• Best for accessory storage → Comecase Headphone Case. The inner mesh pocket holds a USB cable and charger.
• Best for multiple children at home → Hengliyuan Kids Headphones Bulk. No arguing over whose pair is whose when the colors differ.
• Best for wireless listening → neither. The Comecase case holds Bluetooth headphones but doesn't provide audio; the Hengliyuan set is wired 3.5 mm.
• Best for a single adult user → Comecase Headphone Case (paired with the foldable headphones you already own), not the bulk set.
If I had to pick one, I'd buy the Comecase Headphone Case — but only because I'm assuming you already own a compatible pair of foldable headphones and want to keep them in good shape. It's a focused product that does one job: hard-shell protection with a strap, carabiner and mesh pocket, backed by an 18-month warranty.
If you don't own headphones yet, or you're equipping kids, the Comecase case is the wrong purchase. In that case I'd recommend the Hengliyuan Kids Headphones Bulk instead — eight wired pairs with reinforced plugs and a 1-year warranty is a practical, sensible buy for a classroom or a big family. Match the product to the job and neither one disappoints.
It depends on fit, not brand. Comecase lists a long compatibility range, but the case is sized for foldable on-ear and around-ear headphones around 6.1 x 3.35 x 7.87 inches. If your model folds and matches that, it should work. If it doesn't fold, check carefully first.
Yes. They use a standard 3.5 mm wired jack and Hengliyuan lists iPad, tablets, smartphones and PC as compatible. If your device has no headphone jack, you'll need an adapter — that's a device limitation, not a headphone one.
The Hengliyuan bulk set. Eight pairs, eight colors, individually sealed, with reinforced 3.5 mm plugs and a 1.2 m cable built for students. The Comecase case is a single storage item and isn't a substitute for actual headphones.

No. Comecase states clearly that it's case only and the headphones are not included. The package contains one headphone case.
