If you want a hard-shell protector for your JBL on-ear headphones, choose WERJIA Hard Carrying Case; if you need an actual pair of wireless over-ear headphones with Bluetooth, choose FJHBL Over-Ear. That is the honest one-line answer, because these two products are not really competitors at all — one is a case, the other is a headset. The real question is which one solves the problem you actually have right now.
• WERJIA Hard Carrying Case — biggest strength: a molded EVA hard shell that guards compatible JBL Tune on-ear models from bumps, dents and scratches, in a compact, lightweight body.
• WERJIA Hard Carrying Case — biggest trade-off: it holds no electronics at all. It is storage only, sized around a specific list of JBL on-ear headphones, and the case is the only thing in the box.
• FJHBL Over-Ear — biggest strength: a complete wireless headphone with 40mm dynamic drivers, Bluetooth 5.3, dual microphones and up to 20 hours of playtime.
• FJHBL Over-Ear — biggest trade-off: it is a single fixed model in one pink finish, and its comfort and sound depend entirely on how its 200g frame and over-ear cushions suit your head.
• Who each pick is for: WERJIA for someone who already owns compatible JBL Tune on-ears and wants to protect them; FJHBL for someone who needs headphones to listen with in the first place.
The WERJIA case is a protective shell, and it does that one job with a clear design intent. The enclosure is hard EVA — ethylene vinyl acetate — which is the same family of foam-like material used in a lot of molded gear cases because it holds its shape under pressure while staying light. At roughly 0.23 kg, it will not drag down a backpack. The interior is sized at about 7.5 by 2 inches, which is the measurement that matters most here: it is cut for on-ear headphones, not bulky over-ear models.
Compatibility is narrow and specific. WERJIA lists this case for the JBL Tune 520BT, 510BT, 500BT and T450BT. If your headphones are on that list, the fit is the whole point — a snug molded interior keeps the ear cups from shifting, which is exactly what prevents the scratches and dents the product is designed to avoid. The hard shell also means you can stack a bag on top of it or toss it in a carry-on without worrying about crushing whatever is inside.
Who should buy it? Anyone who treats their JBL Tune on-ears as a daily carry item and has been stuffing them loose into a bag. Travelers and commuters get the most out of it, since the compact, lightweight build is explicitly aimed at travel and home storage. Who should skip it? Anyone who does not own compatible JBL on-ear headphones, anyone with large over-ear cans that will not fit a 7.5-inch interior, and — obviously — anyone shopping for headphones rather than protection. If you need to hear music, this case will not help you. And note the listing is case only; the device and accessories are not included.
The FJHBL SY-T3 is a full wireless headphone, and its spec sheet reads like a modern budget-friendly over-ear. The core of it is a pair of 40mm dynamic drivers paired with a Bluetooth 5.3 chip. That combination is aimed at the everyday stuff: music, video and calls, with the lower latency and steadier connection that a newer Bluetooth generation generally brings. There is also a 3.5mm jack and an included audio cable, so you can run it wired with a PC, laptop or anything with a standard headphone port — useful when you want zero wireless hassle or your device has no Bluetooth.
Battery and comfort are the two other pillars. A 400mAh battery is rated for up to 20 hours of continuous playtime, which is a full workday plus change — enough that you are not hunting for a charger every evening. At 200g with soft over-ear cushions, the design leans toward long sessions rather than a tight, clampy fit. The ear cups rotate 90 degrees and fold inward, so the headphone collapses down for a bag or, fittingly, for a case. Dual microphones with noise reduction handle voice capture for calls and online meetings.
Then there is the fun part: customizable RGB lighting, which gives the SY-T3 a look that stands out rather than blending in. The catch is that it comes in one finish — the pink SY-T3 — so if you wanted a neutral color, that is a real limitation. Who should buy it? Someone who needs a wireless headphone for commuting, studying, calls and casual listening, and who likes the idea of RGB flair and wired fallback. Who should skip it? Anyone who already owns headphones they love and only needs to protect them, and anyone who specifically wants a muted, understated look.
• You need to actually listen to audio → FJHBL Over-Ear. WERJIA is a case, not a headphone.
• You already own JBL Tune 520BT, 510BT, 500BT or T450BT → WERJIA Hard Carrying Case. That compatibility list is the reason to buy it.
• Best for battery life → FJHBL Over-Ear. Up to 20 hours from a 400mAh battery.
• Best for protecting a device from bumps and scratches → WERJIA Hard Carrying Case. Hard EVA shell, molded interior.
• Best for travel and commuting → both, for different reasons. WERJIA travels as protection; FJHBL travels as the thing you listen with, and folds for packing.
• Best for calls and online meetings → FJHBL Over-Ear. Dual microphones with noise reduction.
• Best for wired use with a PC or laptop → FJHBL Over-Ear. Bluetooth 5.3 plus an included 3.5mm cable.
• Best for a specific fit guarantee → WERJIA Hard Carrying Case. Its 7.5 x 2-inch interior is sized for named JBL on-ear models, so check your model before buying.
• Best for a bold look → FJHBL Over-Ear. Customizable RGB lighting, in pink.
• Best if you just want a compact storage solution → WERJIA Hard Carrying Case. Lightweight, hard-shell, no electronics to charge.
In my opinion, most people searching these two names together are really deciding between protecting headphones they own and buying headphones they do not. If you already have compatible JBL Tune on-ears, I would buy the WERJIA Hard Carrying Case — a hard EVA shell around a snug 7.5-inch interior is a simple, sensible upgrade to how you carry them, and there is nothing to charge or configure. If you have no headphones yet, I would buy the FJHBL Over-Ear instead: 40mm drivers, Bluetooth 5.3, 20 hours of playtime, dual mics and a wired option cover far more of daily life. Do not buy the case hoping it does anything but protect, and do not buy the headphone hoping it stores itself. Check the current price on Amazon for whichever one matches your actual need.
FAQ
No. The WERJIA is a hard carrying case for compatible JBL Tune on-ear headphones, and the FJHBL is a wireless over-ear headphone. They serve completely different purposes, so the right pick depends on whether you need protection or playback.
I cannot say it will. The WERJIA interior is about 7.5 by 2 inches and is listed for specific JBL Tune models, while FJHBL is a full over-ear design. Fit is not guaranteed, so treat the WERJIA as a match for the JBL models it names rather than a universal case.
Both work, but differently. The WERJIA is a lightweight hard shell built for travel and home storage, so it protects what is inside. The FJHBL folds its ear cups 90 degrees and inward so the headphone itself packs smaller — and it is the one you listen with on the trip.
Ask one question: do you already own JBL Tune 520BT, 510BT, 500BT or T450BT? If yes, the WERJIA case makes sense. If no, and you need something to listen with, the FJHBL Over-Ear is the more useful purchase.
