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, all-in-one wireless listening solution with long battery life and on-ear controls, choose JLab Studio; if you need rugged, crush-resistant protection for a set of full-size studio headphones like the Beyerdynamic DT 770/880/990 PRO, choose Aenllosi Hard Carrying Case. These two products sit at completely different points in the headphone world, and the "versus" framing is really about what job you're trying to get done.
• JLab Studio — biggest strength: It's a full wireless headphone with 30+ hours of Bluetooth 5 playtime, EQ3 sound modes, a built-in mic and earcup controls, so you can actually listen to music out of the box.
• JLab Studio — biggest trade-off: It's an on-ear design with a feather-light build, meaning it prioritizes portability and all-day wear over isolating, heavy-duty sound blocking.
• Aenllosi Hard Carrying Case — biggest strength: Durable EVA construction that's crush resistant, anti-shock and water resistant, giving real protection against bumps, scratches and splashes.
• Aenllosi Hard Carrying Case — biggest trade-off: It's a case only — no headphones, no accessories, nothing to listen with.
• Who JLab Studio is for: Someone who wants wireless headphones for travel, commuting, the beach or lounging, with controls on the earcup and sound you can tune.
• Who Aenllosi Hard Carrying Case is for: Someone who already owns a full-size studio headphone (particularly the Beyerdynamic DT 770/880/990 PRO line) and wants to carry it safely.
The JLab Studio is a wireless on-ear headphone built around one idea: keep it easy. You pair it over Bluetooth 5 and get up to 30+ hours of playtime, with a wireless range of roughly 30 feet (9 meters). For most people that means charging it every few days at most, not every night. The 3-hour charge time is also reasonable if you're the type who plugs in and forgets.
The part I find genuinely useful for daily life is the controls. Play, pause, track skipping and volume all live on the earcup via built-in buttons, and there's a built-in microphone for calls plus voice assistant activation. That means you're not digging your phone out of a pocket every time a song comes on. The EQ3 sound system lets you switch between JLab Signature, Balanced and Bass Boost modes — no app required, which is a nice touch if you don't want another piece of software on your phone.
Comfort and portability are clearly central to the design. The ear cushions and headband use faux leather and cloud foam, the ear cups rotate 80 degrees and fold up into the palm of your hand, and the sliding metal adjustments let you size it. At 5.3 ounces it's light enough to wear for long stretches. The frequency range is 20Hz–20kHz, which is the standard full-range spec you'd expect.
Who should buy it: commuters, travelers, students and casual listeners who want one pair of wireless headphones for music, calls and voice assistants, and who value folding them up and tossing them in a bag.
Who should skip it: anyone who needs true studio-grade isolation or is buying specifically to protect an existing set of wired studio headphones — this is a listening device, not a protective shell. Also note the listing describes a "no warranty" field in one spot while the brand bullet points to a 2-year limited warranty and a 30-day money-back guarantee; if warranty coverage matters to you, it's worth confirming the current terms before buying.
The Aenllosi Hard Carrying Case is a different animal entirely. It's a replacement hard case designed for Beyerdynamic DT 770, 880 and 990 PRO over-ear studio headphones in 32, 80 and 250 Ohm versions. It is explicitly a case only — the headphones and any accessories are not included. So this is not a purchase you make instead of headphones; it's a purchase you make because you already own a set.
What you get is protection. The shell is made of durable EVA, which is crush resistant, anti-shock and water resistant. In practical terms, that addresses the three things that actually damage headphones in a bag: getting squashed by heavier items, taking a knock, and getting caught in rain or a spilled drink. For a full-size studio headphone with a fixed headband and large cups, a soft pouch doesn't really solve any of those. This does.
Inside, there's an internal mesh pocket for storing other accessories — a cable, an adapter, spare pads, whatever you carry alongside your headphones. The external dimensions are listed as 8.27 x 6.88 x 4.13 inches and the case weighs 200 grams (about 7 ounces), so it's light for how much structure it provides. It comes in grey with a solid pattern.
Who should buy it: anyone who owns a Beyerdynamic DT 770/880/990 PRO (or a similarly sized over-ear studio headphone), takes it between home, studio, rehearsal or class, and wants it to arrive undamaged.
Who should skip it: anyone who doesn't already own compatible full-size headphones, or anyone expecting headphones to be in the box. And if your headphones are compact folding on-ears, this case is built around a different footprint — check that your model fits before ordering.
• Best for actually listening to music → JLab Studio. The Aenllosi case produces no sound at all; it's a container.
• Best for protecting an existing studio headphone → Aenllosi Hard Carrying Case. Crush resistant EVA with anti-shock and water resistance is a real step up from a soft bag.
• Best for battery life and wireless freedom → JLab Studio. 30+ hours of Bluetooth 5 playtime and a 9-meter range.
• Best for travel where gear gets knocked around → Aenllosi Hard Carrying Case. This is exactly the scenario its materials are designed for.
• Best for hands-free calls and voice assistants → JLab Studio. Built-in microphone plus earcup controls.
• Best for tuning your sound without an app → JLab Studio. Three EQ3 modes switch directly on the headphones.
• Best for someone who owns multiple headphone accessories → Aenllosi Hard Carrying Case. The internal mesh pocket keeps cables and small parts together.
• Best for a gift where you don't know their gear → JLab Studio. It works on its own; the case only makes sense if the recipient owns the right headphones.
In my opinion, these aren't really competitors — they're two ends of a workflow. If I had to pick one for the average shopper searching this comparison, I'd buy the JLab Studio, because it's a complete product that does something useful on its own: wireless listening, calls, EQ modes and 30+ hours of playtime in a foldable on-ear package. The Aenllosi Hard Carrying Case is the smarter buy only if you already own a Beyerdynamic DT 770/880/990 PRO or similar full-size studio headphone and want to keep it safe. If that's you, buy it without hesitation. If it isn't, the case has nothing to protect.
Just a case. It's a hard carrying case designed as a replacement for the Beyerdynamic DT 770/880/990 PRO line. The headphones and accessories are not included, so you need to already own compatible headphones for it to be useful.
The product information lists a carrying case as part of the design details, along with a micro USB charging cable. If a hard shell is what you specifically want, though, the JLab Studio's case is a soft-style faux leather item — not the crush-resistant EVA shell the Aenllosi case provides.
For commuting, the JLab Studio, because it's the one that actually plays audio and folds up for a bag. The Aenllosi case is only relevant to a commuter if they're carrying a full-size studio headphone back and forth and want it protected.
I can't quote prices here, and they change often. The honest way to decide: figure out which job you actually need done — listening or protecting — then check the current price on Amazon for that one product. Buying the case when you need headphones, or vice versa, is the only real mistake in this comparison.
