• Comecase Hard Headphone Case — biggest strength: a hard EVA middle shell with a smooth PU exterior that resists pressure, drops, dust and light splashes, plus a mesh pocket for a cable.
• Comecase Hard Headphone Case — biggest trade-off: it's storage only. It has no electronics, no audio, and it fits a defined size window (6.89 x 4.92 x 3.3 in internal), so you must measure your folded headphones first.
• Mixiba Sleeping Headphones — biggest strength: an adjustable hook-and-loop headband with Bluetooth 5.4, up to 14 hours of playtime, and on-band buttons so you never reach for your phone.
• Mixiba Sleeping Headphones — biggest trade-off: it's not a protective case, and thin headband speakers trade the isolation and bass weight of traditional over-ears for comfort and a low profile.
• Pick Comecase if you already own foldable headphones and want them to survive a backpack, suitcase, locker or desk drawer.
• Pick Mixiba if you want audio while lying on your side, jogging, lifting or doing yoga without earbuds pressing into your ears.
This is a carrying case, and it's built like one. The outer layer is a smooth PU surface — the listing calls the color Pink, and the enclosure material is polyurethane — wrapped around a hard EVA middle shell. That combination is the whole point: it gives foldable headphones a structured space instead of letting them get crushed at the bottom of a bag. In practice, that means pressure from textbooks, a laptop, or a suitcase that's been overpacked.
The fit list is broad for a single case. Comecase lists compatibility with JBL Tune 520BT and 510BT, TOZO HT3, Picun B8, JLab JBuds Lux ANC, and several Beats models including Solo Pro, Solo3, Solo4, Studio Pro and Studio3. The internal dimensions are 6.89 x 4.92 x 3.3 inches, and the stated maximum compatible device size is 6.8 inches. That's a genuinely useful range, but it's not universal — if your headphones fold into something chunky, they won't go in, and Comecase itself tells buyers to compare the folded size before purchase. Do that. It's the single most common way this kind of purchase goes wrong.
The details are small but sensible. There's a mesh pocket in the upper section for a charging cable or audio cord, which keeps cables from tangling around the ear cups. There's a sturdy hand strap for carrying. The package is one case only — no headphones, no cables, no accessories. Water resistance is listed as water resistant, which covers light splashes and dust from normal commuting, not a soaking.
Who should buy it: commuters, students, office workers and travelers who already own a compatible foldable pair and want it to arrive intact. Who should skip it: anyone who wants audio out of the box, anyone whose headphones don't fold down inside those dimensions, and anyone expecting a soft, squishable pouch — this is the opposite of that.
Mixiba takes a completely different approach. Instead of protecting headphones, it replaces them with a fabric headband holding thin speakers, in Gray, with a hook-and-loop closure. That closure is the feature that matters most. Fixed-size headbands are a gamble — too tight and they give you a headache, too loose and they slide off mid-run. Hooks and loops let you dial the tightness in yourself, and Mixiba explicitly frames it as fitting both men and women with different head sizes.
The audio side is straightforward: Bluetooth 5.4 for the wireless connection, up to 14 hours of listening on a full charge, and roughly a 2-hour charge time. That's a full day of podcasts, audiobooks or music for most people, or several workouts and a night of sleep before you need to plug in. The included components are a cable, the headband headphones, and a user manual, backed by a 1-year warranty description.
Where it earns its place is comfort and sweat. The fabric is soft, breathable and stretchy, and the design is aimed at keeping sweat from running into your eyes while you jog, cycle, lift or do yoga. Because the speakers sit in a band rather than inside your ear canal, there's no earbud pressing against your head when you lie on your side — which is precisely why "sleeping headphones" is in the name. Buttons on the band handle volume, track changes, play/pause and calls, so your phone can stay in your pocket while you cook, travel or train.
Side-by-Side: Which Should You Choose?
• Best for protecting headphones you already own → Comecase Hard Headphone Case. Hard EVA shell, PU exterior, structured interior.
• Best for listening without earbuds → Mixiba Sleeping Headphones. Thin speakers in a soft fabric band, no ear-canal pressure.
• Best for battery life → Mixiba Sleeping Headphones. Up to 14 hours per charge with a 2-hour charge time.
• Best for cable and accessory storage → Comecase Hard Headphone Case. The upper mesh pocket keeps charging cables and audio cords away from the ear cups.
• Best for sweating workouts → Mixiba Sleeping Headphones. The breathable fabric is designed to help keep sweat out of your eyes.
• Best for travel and commuting durability → Comecase Hard Headphone Case. It's sized for backpacks, luggage, lockers and desk drawers, and the shell resists pressure, dust and light splashes.
• Best for side sleeping → Mixiba Sleeping Headphones. A hook-and-loop band with a low profile beats a rigid ear cup against a pillow.
• Best for fit certainty before you buy → Comecase Hard Headphone Case. The numbers are published (6.89 x 4.92 x 3.3 in internal, 6.8 in max device size), so you can measure first.
If I had to pick one, I'd buy the Comecase Hard Headphone Case — but only because it solves a problem almost everyone with foldable headphones eventually has: a crushed or scratched pair after a trip. It's a simple, well-specified product with published dimensions, a hard shell and a cable pocket, and there's nothing vague about what it does.
That said, if your actual goal is listening while you sleep, run or stretch, the case is irrelevant to you. In that situation I'd take the Mixiba Sleeping Headphones for the adjustable hook-and-loop fit, Bluetooth 5.4 and 14-hour playtime. Buy the case to protect, buy the band to listen. Check the current price on Amazon for whichever one matches your problem.
Comecase lists Beats Studio3, Studio Pro, Solo Pro, Solo3 and Solo4 among compatible models, along with JBL Tune 520BT and 510BT, TOZO HT3, Picun B8 and JLab JBuds Lux ANC. Measure your folded headphones against the 6.89 x 4.92 x 3.3 in interior before ordering.
Yes — that's a primary use case. The fabric is soft, breathable and stretchy, the hook-and-loop closure lets you tighten the fit, and the design helps keep sweat from running into your eyes. The on-band buttons let you change tracks without pulling out your phone.
No. They use thin headband speakers rather than in-ear tips or active noise cancellation, so they don't seal your ear canal. That's the trade-off for being able to lie on your side and still hear your surroundings, which many sleepers and outdoor runners actually prefer.
Yes. There's an upper mesh pocket sized for small accessories like charging cables or audio cords, which keeps them separated from the headphones. The package includes the case only — headphones, cables and other accessories are not included.
