If you want a fun, retro-styled wired headphone for casual everyday listening, choose JJLFresheners Orange Retro Over-Ear; if you need a kid-safe headphone with a USB-C plug and a hard volume ceiling, choose KONNAO Upgrade USB Type. Those two sentences are basically the whole decision — everything below is me showing my work so you can sanity-check that call against your own situation.
• JJLFresheners Orange Retro Over-Ear — biggest strength: A bold orange retro design with a foldable, lightweight build (listed at just 0.03 kg) and cushioned on-ear cups, plus a standard 3.5 mm jack that fits most phones, tablets and MP3 players.
• JJLFresheners Orange Retro Over-Ear — biggest trade-off: No volume limiting and no noise control at all, and the 3.5 mm plug won't work with newer phones or tablets that dropped the headphone jack.
• KONNAO Upgrade USB Type — biggest strength: A switchable 85 dB / 94 dB volume limit and a native USB-C connector built for school-issued tablets and laptops — plug and play, no adapter.
• KONNAO Upgrade USB Type — biggest trade-off: It's explicitly a kids' product, it only works with devices that carry audio over USB-C, and it won't fit adult-sized heads or adult listening habits well.
• Who each pick is for: JJLFresheners for teens and adults who want a cheap-looking-fun, wired, retro headphone for music on the move; KONNAO for parents buying for a child over 3 who uses a USB-C tablet or Chromebook.
The JJLFresheners Orange Retro Over-Ear is a style-first wired headphone. Orange enclosure, orange carry case, "Retro" as the declared style theme — this is a product you buy partly because you like how it looks on your head. The audio side is conventional but reasonable on paper: a dynamic driver rated 20 Hz to 20,000 Hz, which is the standard full-range spec you'd expect from a general-purpose music headphone. Nothing exotic, nothing obviously compromised.
Where it earns its keep is portability. The foldable design and the very low listed weight make it the kind of thing you toss in a bag and forget about until you need it. The cushioned ear cups and adjustable headband are aimed at longer sessions, and the on-ear/over-ear hybrid shape (the sheet lists on-ear placement with an over-ear earpiece shape) is a familiar, comfortable compromise for casual listening. There's a media control on the cable, so you can pause and skip without pulling your phone out.
Who should buy it: teens and adults who still use devices with a 3.5 mm headphone jack, who want a distinctive retro look, and who treat headphones as a casual accessory rather than a critical tool. It's also a reasonable pick if you want something light for a commute, a walk, or a desk.
One honest note on build: the enclosure material is listed as fabric and foam, not metal or hard plastic. That reads as a lightweight, friendly-feeling headphone rather than a rugged one. Treat it accordingly.
KONNAO Upgrade USB Type: Who It's For
The KONNAO Upgrade USB Type is a purpose-built kids' headphone, and the design choices make that obvious the moment you read the spec sheet. The headline feature is the switchable volume limit: 85 dB for normal environments, 94 dB for noisy ones. That's not a marketing flourish — it's a concrete, checkable safety feature, and it's the single strongest reason to buy this over a generic pair of cheap headphones for a child.
The second defining feature is the connector. This is a USB-C headphone, built for the tablets, laptops and school devices that carry audio over Type C. The manufacturer is explicit that it's plug and play with no converter needed — but also explicit that it is not compatible with USB-C charging ports. That distinction matters a lot. A USB-C port on a device isn't automatically an audio port, and if you plug this into the wrong one you'll get nothing. Check your child's device first.
Comfort and safety are clearly the design priorities. The oval over-ear cups use soft foam and breathable protein leather, the frame deliberately avoids metal parts to keep the weight down, and the shell is described as streamlined with no 90-degree sharp corners. For a product aimed at kids over 3, those are the right calls. There's also a microphone, which makes it usable for online classes and video calls, plus passive noise cancellation — meaning the cup seal reduces some ambient sound, not electronics.
Who should buy it: parents and guardians buying for a child over 3 who uses a USB-C tablet, Chromebook or school laptop, and who specifically want a hard cap on volume. The two-year replacement warranty and stated lifetime technical support are worth noting as a long-term ownership factor for a product a child will probably abuse.
Side-by-Side: Which Should You Choose?
• Best for child hearing safety → KONNAO Upgrade USB Type. The 85 dB / 94 dB switch is a real, specific safety mechanism the JJLFresheners simply doesn't have.
• Best for retro style and casual adult listening → JJLFresheners Orange Retro Over-Ear. Orange finish, retro theme, matching carry case.
• Best for modern USB-C school devices → KONNAO Upgrade USB Type. Native Type C, plug and play, no adapter to lose.
• Best for older phones, MP3 players and tablets with a headphone jack → JJLFresheners Orange Retro Over-Ear. The 3.5 mm jack is the more universally compatible standard here.
• Best for portability and light carry → JJLFresheners Orange Retro Over-Ear. Foldable, and listed at 0.03 kg.
• Best for online classes and calls → KONNAO Upgrade USB Type. It's the only one of the two with a microphone.
• Best for comfort over long sessions on a small head → KONNAO Upgrade USB Type. Metal-free lightweight frame, oval over-ear cups, no sharp corners.
• Best for a wide frequency range on paper → JJLFresheners Orange Retro Over-Ear. Its sheet declares a 20 Hz – 20,000 Hz range; KONNAO lists impedance (25 ohm) but no frequency range.
If I were buying for myself — an adult who wants a fun, light, wired headphone for music — I'd take the JJLFresheners Orange Retro Over-Ear. The retro look is the point, the foldable lightweight build suits carrying it around, and the 3.5 mm jack works with the gear I already own. If I were buying for a child, my answer flips completely and I'd take the KONNAO Upgrade USB Type without hesitation: the switchable 85/94 dB limit is the feature that actually matters, and the USB-C plug matches how school devices are built now. Match the product to the person, and this decision takes about ten seconds.
FAQ
Yes — that's its core design goal. It has a switchable limit of 85 dB for everyday listening and 94 dB for noisy settings, and it's aimed at children over 3. If hearing protection is your priority, this is the one to pick.
The KONNAO Upgrade USB Type, mainly because it includes a microphone and a USB-C connector designed for school tablets and PCs. Just confirm your child's device sends audio through its USB-C port — the manufacturer notes it won't work with USB-C charging ports.
Not actively. The JJLFresheners lists noise control as "None." The KONNAO lists passive noise cancellation, which means the over-ear cup seal reduces some surrounding sound rather than using electronics. Neither blocks noise the way active cancellation does.
Both are budget-tier wired headphones, but I don't quote figures here. Check the current price on Amazon using the button on this page before you decide — that's the only number that matters at checkout.
