• L LTGEM Case — biggest strength: a molded, impact-resistant EVA shell built around specific JBL Tune and JBL Live models, with a mesh pocket for cables and a 360-degree zipper. It is protection first, nothing else.
• L LTGEM Case — biggest trade-off: it is a case only. No headphones, no audio, no electronics. If you don't own a compatible JBL model, it does nothing for you.
• AIAUXAI Open Ear Headphones — biggest strength: an open-ear hook design that sits outside your ear canal, plus a 3.5mm wired connection that works with laptops, Chromebooks, tablets and phones without any charging or pairing.
• AIAUXAI Open Ear Headphones — biggest trade-off: it is wired, so you are tethered to your device, and the open-ear shape means you get sound isolation rather than full noise blocking.
• Who each pick is for: the L LTGEM Case is for someone who already owns a compatible JBL headphone and wants to carry it safely. The AIAUXAI Open Ear Headphones are for someone who wants a lightweight, wired, ear-hook headphone for work, calls or workouts.
The L LTGEM Case is a single-purpose product, and I mean that as a compliment. It exists to hold one of a specific list of JBL headphones: the Tune 770NC, 510BT, 720BT, 520BT, 520C and 670NC, plus the JBL Live 770NC, 670NC, 680NC and 780NC. The brand also lists the JBL E45BT and Live 650BTNC among compatible models. That compatibility list is the whole story. If your headphone is on it, this case fits. If it isn't, this case is not for you.
What it does well comes down to materials and shape. The exterior is hard EVA — a foam-like material that holds its form under pressure — and L LTGEM describes it as shockproof, semi-waterproof and dustproof. Translation for real life: it survives being crushed at the bottom of a backpack, it shrugs off a splash of rain, and it keeps dust out of the earcups. Outer dimensions are 8.1 by 6.8 by 2.9 inches, and the maximum compatible device size is 6.8 inches, so it stays compact enough to slide into a carry-on or a school bag without eating the whole compartment. Inside, there's a mesh pocket for a charging cable or an audio cable, and the zipper runs a full 360 degrees for easy opening.
The details are where a case lives or dies, though, and this one has a mixed reputation in the listing's own description. The same description notes complaints about a flimsy build, a handle that can rip, a zipper that can stick or break, and an odor when new. I take those at face value — they're the kind of issues that show up in hard-shell cases at this tier. So buy it for the shell and the fit, and treat the strap and zipper as the weak points. Air it out before you pack a headphone in it.
Who should buy it: anyone with a compatible JBL Tune or JBL Live model who wants a dedicated hard case instead of tossing headphones loose into a bag. Who should skip it: anyone without a compatible headphone, anyone expecting premium hardware, and anyone who wants audio — this is a case, and the listing is explicit that the headphone is not included.
The AIAUXAI Open Ear Headphones solve a completely different problem. These are wired, open-ear headphones with a hook that wraps over your ear rather than a cup that seals around it. The earpiece shape is a hook, the ear placement is open ear, and the enclosure is thermoplastic elastomer — a rubbery, flexible material that bends instead of cracking. That combination is the point: nothing is jammed into your ear canal, so sensitive ears get a break, and the hook keeps the earpiece from sliding off during movement.
Connectivity is old-school in the best way. There's a 3.5mm jack, a 4.92-foot tangle-resistant cable, and a 90-degree reinforced plug. No pairing, no battery, no app. Plug it into a laptop, a Chromebook, a desktop PC, a Kindle Fire, an iPad, or one of the many Samsung Galaxy models AIAUXAI lists — the A15, A14, A25, A53, S10 and more — and it works. The angled plug is a small but smart touch for phones in a pocket, where a straight plug tends to get bent over time.
There's a remote on the cable with button controls, including volume control, and a built-in microphone for calls and video meetings. Noise control is listed as sound isolation, which is honest: an open-ear design lets the world in, so you hear traffic, coworkers and announcements. For running, cycling or an office where you need to stay aware, that's a feature, not a flaw. For blocking out a loud commute, it isn't.
In the box you get the headphones and a carrying case — a nice detail, since a small case keeps the cable from becoming a knot in a bag. The age range is listed as over 7 years old, so it's a reasonable pick for kids on school devices too.
Who should buy it: students, remote workers, runners, and anyone with a 3.5mm port who wants a light, tangle-resistant, no-charging headphone. Who should skip it: anyone who needs wireless freedom, deep noise cancellation, or a sealed, immersive soundstage.
• Best for protecting an existing JBL headphone → L LTGEM Case. It's a hard EVA shell sized for specific JBL Tune and JBL Live models.
• Best for actually listening to audio → AIAUXAI Open Ear Headphones. The case makes no sound.
• Best for travel storage → L LTGEM Case. At 8.1 x 6.8 x 2.9 inches with a mesh accessory pocket, it's built for a backpack or carry-on.
• Best for workouts and running → AIAUXAI Open Ear Headphones. The ear hook and TPE build are designed for movement, and the open ear keeps you aware of your surroundings.

• Best for zero charging and zero pairing → AIAUXAI Open Ear Headphones. A 3.5mm wired connection just works when you plug it in.
• Best for sensitive or small ears → AIAUXAI Open Ear Headphones. The open-ear hook avoids inserting anything into the ear canal.
• Best for durability under pressure → L LTGEM Case. Hard EVA is shockproof, semi-waterproof and dustproof — though the handle and zipper are the parts to watch.
• Best for owners of non-JBL headphones → AIAUXAI Open Ear Headphones. The case's fit list is narrow and brand-specific.
In my opinion, the right answer depends entirely on what you're missing. If you already own a JBL Tune 770NC, 510BT, 720BT, 520BT, 520C, 670NC or a JBL Live 770NC, 670NC, 680NC or 780NC, I'd buy the L LTGEM Case — a hard shell beats a loose headphone in a bag every time, as long as you accept that the strap and zipper are the weak links. If you need headphones, I'd buy the AIAUXAI Open Ear Headphones. Wired, hook-shaped, open-ear and ready for a laptop, a phone or a run. Two products, two jobs. Buy the one your situation is actually missing.
FAQ
Neither. They connect through a 3.5mm jack with a 4.92-foot cable, so there's no battery to charge and no pairing to set up. Your device just needs a 3.5mm audio port.
Not much. AIAUXAI lists the noise control as sound isolation, and the open-ear hook design deliberately leaves your ear canal open. That's great for awareness while running or working, but it's not the tool for blocking engine noise.
They're not really comparable, since one is a case and one is a headphone. Decide what you're short on, then check the current price on Amazon before you commit.
