How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a complete, self-contained listening setup you can fold up and take anywhere, choose Coby Over-Ear Headphones; if you need a dedicated hard shell to protect a pair of folded JBL headphones you already own, choose Againmore Hard Headphone Case. These two products sit at opposite ends of the same idea — one is the sound, the other is the armor.
• Coby Over-Ear Headphones — biggest strength: a full wireless over-ear headset with Bluetooth 5.3, a built-in mic, button controls, a 3.5 mm AUX input, a TF card slot and a foldable frame — everything you need to actually listen, in one box.
• Coby Over-Ear Headphones — biggest trade-off: battery life is listed at up to 5 hours, which is short by modern standards, and there's no active noise cancellation. You'll be charging it often and you'll still hear the bus.
• Againmore Hard Headphone Case — biggest strength: a hard EVA shell with wave foam, velvet lining, an elastic accessory mesh pocket and a carry handle, sized for folded JBL Tune and JBL Live models.
• Againmore Hard Headphone Case — biggest trade-off: it makes no sound at all and fits a specific shortlist of JBL models. If your headphones aren't on that list, or aren't foldable, this case isn't for you.
• Who each pick is for: Coby if you need headphones; Againmore if you already own compatible JBL headphones and want to stop tossing them loose into a bag.
The Coby set is an all-in-one budget wireless headphone. The spec sheet reads like a checklist of the basics done properly: Bluetooth 5.3 with a stated range of about 33 feet, 40 mm dynamic drivers, a 20 Hz–20,000 Hz frequency range and 32 ohm impedance. That's a conventional, easy-to-drive configuration — the kind of setup that pairs with a phone or laptop without fuss and plays well at modest volume. The over-ear cups sit around your ears rather than on them, and the ABS build keeps the whole thing light at roughly 4 ounces.
What stands out to me is the redundancy of inputs. You get Bluetooth for wireless listening, a 3.5 mm AUX jack for a wired connection when the battery is flat or when you're on a plane seat-back screen, and a TF card slot for offline playback. Button controls on the earcup handle play, pause, track skipping and calls, and there's a built-in microphone for hands-free use. The headband adjusts and the whole headset folds down for storage — that foldability is the thread that connects this comparison, and it's genuinely useful for commuters, students and travelers who want the headphones to disappear into a bag.
Who should skip it? Two groups. First, anyone who needs long battery life — up to 5 hours of playback means charging most days if you listen a lot, and there's no noise cancellation listed, so noisy commutes will come through. Second, anyone chasing premium sound or premium materials; this is a functional everyday headset, not a hi-fi one.
Againmore Hard Headphone Case: Who It's For
This is a storage product, and it's honest about being one. The Againmore case is built around a hard EVA shell with a polyester and mesh exterior, lined with soft velvet so the earcups and headband rest against something gentle rather than a hard plastic tray. Inside, thick wave-shaped foam in the lid fills the empty space above folded headphones, which is the part that matters: it's designed to reduce shifting and rubbing around the earcups, headband and swivel joints when the case gets bounced around in a backpack.
The fit is specific. The interior is a calibrated 8.07 x 6.10 x 0.98 inches, oval-shaped, and it's intended for folded JBL Tune 510BT, 520BT, 720BT, 770NC and 670NC, plus JBL Live 770NC, 780NC, 680NC and 670NC. Againmore is upfront that headband settings change how a headphone sits, so you should compare your folded dimensions before ordering. That's the right advice — a case that's slightly too tight presses on hinges, and one that's too loose lets things rattle.
There's also an upper elastic mesh pocket for charging cables and small adapters, which keeps cords from tangling around the headband or scratching the earcups. Externally it measures 8.46 x 6.70 x 2.56 inches, with a smooth zipper and an integrated carry handle. It weighs about 4.8 ounces. The EVA shell can shrug off light splashes, but it isn't waterproof and shouldn't be submerged, and Againmore is clear that it's protective against everyday bumps and light compression — not crushproof or drop-proof.
Who should buy it? Anyone who owns one of those JBL models, folds them, and currently buries them loose in a bag. Students, commuters and frequent travelers get the most out of it. Who should skip it? Owners of non-listed headphones, non-foldable headphones, or anyone expecting a waterproof or genuinely crushproof hard case. Also note: the case is sold alone — no headphones, cables or adapters included.
• Best for actually listening to music → Coby Over-Ear Headphones. It's the only one of the two that makes sound.
• Best for protecting headphones you already own → Againmore Hard Headphone Case. Hard shell, wave foam, velvet lining, mesh pocket.
• Best for wired backup and offline playback → Coby. 3.5 mm AUX input plus a TF card slot give you two fallbacks when Bluetooth isn't an option.
• Best for long listening sessions → neither, honestly. Coby's up to 5 hours is modest, and the case has no battery at all.
• Best for commuting and travel organization → Againmore. The carry handle, slim oval profile and accessory pocket are built for bags, lockers and carry-ons.
• Best for hands-free calls → Coby. Built-in mic and on-earcup button controls.
• Best for folded-headphone storage → Againmore, provided your model is on the JBL list and your folded dimensions fit the 8.07 x 6.10 x 0.98 in interior.
• Best for a single all-in purchase → Coby. One box gets you headphones, cables and a manual; the case is a companion, not a kit.
If I had to pick one, I'd buy the Coby Over-Ear Headphones. It's the more complete product: wireless and wired listening, a mic, call controls, a card slot, a foldable frame and a 1-year warranty, all in one package. The Againmore case is well thought out for what it is — I'd genuinely recommend it to a JBL Tune or JBL Live owner who wants to stop their headphones from rattling around a backpack. But it can't play a single note. Buy the Coby if you need headphones; add the Againmore case separately if you own compatible JBL cans and want to keep them tidy.

FAQ
Not per the data. Againmore lists the case for specific folded JBL Tune and JBL Live models with an 8.07 x 6.10 x 0.98 in interior. It may fit other headphones, but Againmore advises comparing your folded dimensions, and I wouldn't assume compatibility without measuring.
No. The spec sheet lists noise control as "None." The over-ear design gives you some passive isolation from the cups themselves, but there's no active noise cancellation, so loud environments will still come through.
They do different jobs, so it's not a like-for-like comparison. Coby gives you a working headset with wireless, wired and card playback plus a 1-year warranty; Againmore gives you a protective shell with no electronics. Check the current price on Amazon for each and decide based on whether you need sound or storage.
No to both. The EVA shell helps resist light splashes and everyday bumps, and the wave foam reduces shifting and rubbing, but the case is not waterproof, should not be submerged, and is not crushproof or drop-proof.
