If you want a soft, stretchy travel pouch that keeps foldable on-ear headphones like JBL Tune and Sony MDR-ZX models safe in a bag, choose Weatwo On-Ear Headphones Storage; if you need wired USB-C on-ear headphones with a 94dB volume cap for a kid's school tablet, choose Bywulanda Upgrade USB Type.
• Weatwo On-Ear Headphones Storage — biggest strength: Neoprene stretch pouch that fits a long list of foldable on-ear models (JBL Tune 500BT/510BT/660NC/600BTNC, Sony MDR-ZX100/ZX110/110NC, WH-CH500/510/520 and more) within an 8.3 x 7.2 x 0.9 in range, with a wrist strap and a mesh pocket for cords.
• Weatwo On-Ear Headphones Storage — biggest trade-off: It is a soft case, not a hard shell. The specs say it is not as shockproof as a hard case, so a hard drop is not what it is built for.
• Bywulanda Upgrade USB Type — biggest strength: Plug-and-play USB-C wired on-ear headphones with a 94dB safe volume limit, 40mm dynamic drivers, a 20Hz–20,000Hz range and an adjustable foldable headband in mint green.
• Bywulanda Upgrade USB Type — biggest trade-off: Wired USB-C only. If your device has a 3.5mm jack or Lightning port, this is the wrong connector for you.
• Who each is for: Weatwo is for anyone who already owns foldable on-ear headphones and wants cheap insurance against scratches and dust. Bywulanda is for parents buying a first pair of headphones for a kid's tablet or school device with a USB-C port.
This is a storage bag, not a pair of headphones — worth saying plainly, because the two products in this comparison are not even the same category. The Weatwo case is a stretchy neoprene pouch measuring roughly 8.3 x 7.2 x 0.9 inches and weighing 69g. It is built for foldable on-ear headphones that fall inside that footprint, and the compatibility list is unusually specific: JBL Tune 450BT, 510BT, 500BT, 660NC and 600BTNC; Sony MDR-ZX100, ZX110, ZX110NC, ZX110AP, ZX110P, ZX220BT, ZX300, ZX310, ZX330BT, WH-CH500, WH-CH510, WH-CH520, plus a long tail of MDR-V and XB models. If your headphones fold and sit inside that size range, this bag is designed for them.
Who should buy it: anyone who travels with foldable on-ear headphones and has been tossing them loose into a bag, and anyone who wants a spare pouch for a drawer or a second pair. Who should skip it: people who need hard-shell, shockproof protection, and people whose headphones do not fold or exceed the 8.3 x 7.2 x 0.9 inch range — the brand itself suggests checking your headphone dimensions first and asking for a compatibility guide if you are unsure.

Bywulanda Upgrade USB Type: Who It's For
The Bywulanda Upgrade USB Type is a completely different animal: actual wired on-ear headphones aimed at kids and students, in a mint green plastic build that weighs about 0.18 kg. The headline feature is the 94dB safe volume limit. That is the whole point of the product — the design exists to cap loudness so a child's ears are not exposed to the kind of level an adult pair can reach. If hearing protection is the reason you are shopping, this spec is the one that matters.
The connector is USB-C, and it is the upgraded part of the name: no adapter, no dongle, just plug straight into a tablet, phone or laptop with a Type-C jack. Sound comes from 40mm dynamic drivers with a 20Hz–20,000Hz frequency range and 30 ohm impedance, and the sound profile is aimed at clear stereo for cartoons, videos and school apps rather than studio listening. The headband is adjustable enough to grow with a kid from young child through teenager, and the whole thing folds down for travel. There is a button-based volume control on the ear cup and passive sound isolation, so it blocks a bit of classroom or car noise without any active circuitry.
Who should buy it: parents who want a first proper pair of headphones for a tablet, a school device or a long car ride, and who specifically want the volume ceiling. Who should skip it: anyone whose device only has a 3.5mm headphone jack, anyone who wants wireless Bluetooth, and adult listeners who want a flat, detailed sound — this is tuned and capped for children, not for critical listening.
• Best for protecting headphones you already own → Weatwo On-Ear Headphones Storage. It is a pouch, and that is exactly the job.
• Best for a kid's tablet or school device → Bywulanda Upgrade USB Type. USB-C plug-and-play with a 94dB volume limit built in.
• Best for travel packing → Weatwo. 69g, folds flat, stretches, and has a wrist strap plus a mesh pocket for cables.
• Best for hearing safety → Bywulanda. The 94dB cap is the single most important line in its spec sheet.
• Best for JBL Tune and Sony MDR-ZX owners → Weatwo. Those exact models are named in the compatibility list.
• Best for wired USB-C audio on the go → Bywulanda. No adapter needed, 40mm drivers, foldable headband.
• Best for shock protection → neither, strictly speaking. Weatwo says it is not as shockproof as a hard case, and Bywulanda is headphones, not a case.
• If you are unsure about the pouch fit → check your headphone dimensions first. Weatwo asks buyers to measure before ordering and offers a compatibility guide for unlisted models.
In my opinion these two products should not be competing at all, and that is the honest answer. If you already own foldable on-ear headphones like a JBL Tune or Sony MDR-ZX and you want a light, stretchy, genuinely pocketable pouch to stop them getting scratched in a bag, I would buy the Weatwo On-Ear Headphones Storage. If instead you are shopping for a child who needs wired headphones for a USB-C tablet or school device, and you care about a volume ceiling, I would buy the Bywulanda Upgrade USB Type — the 94dB limit is the reason to pick it. Buy the one that matches your problem, not the one that sounds better on paper.
FAQ
what are the best open ear headphones
"Open ear" and "on-ear" are different things, and neither product here is an open-ear design. The Bywulanda Upgrade USB Type is an on-ear, wired USB-C headphone with 40mm dynamic drivers and a 94dB volume cap, and the Weatwo is a storage pouch for foldable on-ear headphones. If you specifically want open-ear, neither of these is what you are looking for.
On-ear headphones sit against the ear rather than around it, which makes them lighter and more compact than over-ear models — that is precisely why both of these products are built around that format. The Bywulanda's adjustable foldable headband and 0.18 kg weight are typical on-ear advantages. The trade-off is less passive isolation than a full over-ear cup, though the Bywulanda does list sound isolation.
are open ear headphones good
That depends on what you want from them, and again, these are not open-ear products. The Bywulanda is an on-ear wired headphone with 30 ohm impedance and a 20Hz–20,000Hz range, capped at 94dB for children. If your priority is hearing safety rather than open-ear airflow, the volume limit on the Bywulanda is the feature that matters here.
are on ear headphones comfortable
Comfort on on-ear models comes down to weight and headband adjustment. The Bywulanda weighs about 0.18 kg and has an adjustable headband the brand describes as expanding to fit heads from kids to teenagers, which is the main comfort lever on a budget on-ear pair. If you are asking about your existing headphones rather than these, note that the Weatwo pouch simply stores them — it has no bearing on how they feel on your head.
