• JLab Neon on-Ear — biggest strength: wired simplicity with 40mm neodymium drivers, an inline mic and remote, and a limited lifetime warranty.
• JLab Neon on-Ear — biggest trade-off: it is a wired 3.5mm headphone, so there is no Bluetooth and no true wireless freedom.
• iClever BTH20 — biggest strength: Bluetooth 5.4 with up to 60 hours of play time and active noise cancelling in one lightweight package.
• iClever BTH20 — biggest trade-off: it is built and tuned for kids, with an 80dBA volume limit and a 32-ohm, kid-first sound profile.
• Who each pick is for: the JLab Neon suits teens and adults who want a plug-and-play wired pair for a phone, laptop or console; the iClever BTH20 suits parents buying for a child aged 3 and up.
The Neon is a wired on-ear headphone built around a 40mm dynamic driver with a 20Hz–20kHz frequency range. JLab describes that driver as delivering rich bass, clear mids and crisp highs, and the tuning is aimed at everyday listening — music, movies and podcasts rather than studio work. Because it is a passive wired design, the sound you get is the sound the driver produces; nothing is processing or compressing it along the way.
The physical design is where this pair earns its keep. It folds, the ear cups rotate up to 80 degrees, and the headband slides on metal adjustments, so it collapses into roughly the size of your palm. The ear cushions are eco leather over cloud foam, and the whole thing is described as featherlight. For a student stuffing a bag between classes or someone who wants a headphone that lives in a jacket pocket, that matters more than any spec sheet number.
iClever BTH20: Who It's For
The BTH20 is a different animal entirely. It is an over-ear wireless headphone with active noise cancelling, Bluetooth 5.4 and a 10-metre wireless range, and iClever positions it squarely at kids aged 3 and up. The 40mm dynamic driver here runs at 32 ohms across the same 20Hz–20kHz range, but the story is not the driver — it is the safety layer wrapped around it.
That layer is iClever's Sound Refiner and 80dBA volume limit technology, which the brand says reduces volume in the frequency range where young ears are most vulnerable while keeping the sound clear and balanced. In my opinion, that is the single most important feature on this headphone, and it is the reason a parent would pick it over a general-purpose pair. Active noise cancelling then does the rest of the work on a flight or a long car ride.
Battery life is the other headline: 60 hours with ANC off, 35 hours with ANC on, and a 10-minute USB-C charge gives about 5 hours of use. That is enough that a child's travel week happens on a single charge. A 3.5mm audio cable is included too, so the headphone still works when the battery does not. Build quality is pitched at kids specifically — BPA- and PVC-free materials, reinforced internals, and larger buttons that small hands can actually find. The 90-degree rotatable ear muffs and 10-level adjustable headband cover growing heads. It weighs 220g and comes with a 12-month warranty. Skip it if you are an adult who wants a neutral, uncoloured sound signature — the tuning and the volume ceiling are not designed for you.
Side-by-Side: Which Should You Choose?
• Best for wired, zero-hassle listening → JLab Neon on-Ear. Plug into a 3.5mm jack and you are done; no pairing, no charging.
• Best for battery life → iClever BTH20. Up to 60 hours with ANC off, versus a wired headphone that never needs charging at all but also never leaves the cable behind.
• Best for young children → iClever BTH20. The 80dBA volume limit and Sound Refiner are built for exactly this.
• Best for travel and commuting as an adult → JLab Neon on-Ear. The folding frame, rotating cups and 90-degree jack make it the more packable option.
• Best for long-term ownership confidence → JLab Neon on-Ear. JLab's limited lifetime warranty is the stronger coverage of the two, against iClever's 12 months.
• Best for hands-free calls on the move → JLab Neon on-Ear. The inline mic and remote keep everything on the cable.
• Best for kids' wireless freedom → iClever BTH20. Bluetooth 5.4 with a 10-metre range and large, kid-friendly buttons.
In my opinion, the right buy depends entirely on who is wearing them, and that is why I would not call one universally better. For a child aged 3 and up — especially one who travels — I would buy the iClever BTH20, because the 80dBA volume limit, the ANC and the 60-hour battery are three things the Neon simply cannot offer. For a teen or adult who wants a wired, folding, comfortable on-ear with an inline mic and a lifetime warranty, I would buy the JLab Neon on-Ear. If you are still weighing it, check the current price on Amazon for both before deciding, since that gap often settles the question faster than any spec.
what is 40mm driver in headphones
A 40mm driver is the circular speaker unit inside the ear cup, measured across its diameter. Forty millimetres is a common size for on-ear and over-ear headphones — both the JLab Neon and the iClever BTH20 use a 40mm dynamic driver with a 20Hz–20kHz frequency range.
what are 40mm drivers in headphones
They are the moving-coil speaker components that convert the electrical signal into sound. A larger driver generally moves more air, which is why 40mm units like the ones in these two headphones tend to produce fuller bass than the small drivers found in most earbuds.
which driver is best for headphones
There is no single best driver size — it depends on the design goal. Driver size, driver type and tuning all interact, so a 40mm dynamic driver can be tuned for punchy bass, as in the JLab Neon, or for a safer, balanced signature, as in the iClever BTH20.
is 40mm driver good for headphones
Yes, 40mm is a solid, proven size for on-ear and over-ear headphones. Both products here pair a 40mm dynamic driver with a 20Hz–20kHz range, which is enough to cover the full span of normal music and speech content.
