If you want a featherweight, fold-flat on-ear headband set that disappears into a bag and simply works with a wired connection, choose JVC HAS140P; if you need a kid-friendly wired headphone with a longer 5 ft cord, a 24-month warranty, and a design built to fit children as young as two, choose noot products K11.
• JVC HAS140P — biggest strength: Very light at 3.2 ounces with a flat-foldable headband design and a wide 20Hz–24,000Hz frequency range.
• JVC HAS140P — biggest trade-off: It's a wired on-ear headband model with a shorter, more basic feature list and no stated warranty beyond the standard one-year parts and labor coverage.
• noot products K11 — biggest strength: Built for kids (fits ages 2 and up) with a 5 ft tangle-free cord, foldable frame, and a 24-month warranty.
• noot products K11 — biggest trade-off: It runs heavier at 6 ounces, tops out at 20,000Hz, and has no microphone, so it won't handle calls on its own.
• Who each pick is for: JVC HAS140P suits adults who want a light, packable wired headphone for casual listening; noot products K11 suits parents buying for young kids who need a durable, adjustable, travel-friendly option.
The JVC HAS140P is a wired, on-ear headband headphone with a flat-foldable design. That fold-flat hinge is the headline feature here. It means the earcups collapse down so the whole thing slips into a backpack pocket or a seat-back pouch without much fuss. At 3.2 ounces, it's one of the lighter options in this comparison, and that matters if you wear headphones for a while — light sets tend to feel less noticeable on the head over long stretches.
On the audio side, the specs list a 32-ohm impedance and a frequency range of 20Hz to 24,000Hz. That 24,000Hz ceiling is worth noting: it extends past the 20,000Hz mark that many budget headphones stop at, which in plain terms means it's built to reproduce the upper end of the audible range more completely. Whether you actually hear a difference depends on your ears and your source, but the design intent is clear. The impedance of 32 ohms is a friendly number for phones, tablets, and laptops — it doesn't demand a dedicated amp to get decent volume.
noot products K11: Who It's For
The noot products K11 is a wired on-ear headphone designed with kids in mind. The 3.5mm jack plugs into iPads, Kindle Fire tablets, Chromebooks, and desktop computers directly. For newer gear without a headphone jack — iPhone 7 through 14, or an iPad Pro 11/12.9 from 2020 — you'll need an adapter (Lightning to 3.5mm, or USB-C to 3.5mm for iPhone 15 and up). That's a real-world detail worth knowing before you buy, because it decides whether the K11 works out of the box with your device.
The fit is the other big story. The adjustable headband is sized to fit kids as young as two, and it's also stated to fit adults, so it can stretch across a family rather than locking you into one user. The on-ear cushions are padded, and the design is described as plush, which is aimed at comfortable extended wear — a genuine concern for kids who wear headphones for long school or travel sessions. The foldable construction pairs with the 5 ft tangle-free cord, so it travels well and gives a little slack when a child is plugged into a tablet on a plane or in the back seat.
The cable is also where you'll notice the wiring: the K11 has no microphone. You can still talk into the device itself and the other person will hear you, but the headset won't pick up your voice on its own. There's push-button volume control and sound isolation, which helps on noisy planes since the design is meant to play loud enough to mask engine noise. Who should buy it? Parents buying for young kids, especially for school, travel, or tablet use, who want a warranty they can lean on. The 24-month warranty with reachable customer service is a meaningful safety net for a kids' product. Who should skip it? Anyone who needs a mic for calls or video class, or who wants the absolute lightest set — at 6 ounces it's heavier than the JVC.
Side-by-Side: Which Should You Choose?
• Best for light weight → JVC HAS140P. At 3.2 ounces versus 6 ounces, the JVC is the lighter set on the head.
• Best for a longer cable → noot products K11. The 5 ft tangle-free cord gives more room to move than a basic short-cord setup.
• Best for extended high-frequency range → JVC HAS140P. Its 20Hz–24,000Hz range reaches higher than the K11's 20Hz–20,000Hz.
• Best for warranty peace of mind → noot products K11. The 24-month warranty is longer than the JVC's stated one-year parts and labor coverage.
• Best for shared family use → noot products K11. The adjustable band spans kids and adults, so one pair can move between users.
• Best for calls → neither, strictly speaking. The K11 has no mic, and the JVC doesn't list one either. If you need hands-free voice, look elsewhere.
• Best for a simple adult commuter set → JVC HAS140P. Foldable, light, wired, and no kid-specific sizing to think about.
In my opinion, the right pick comes down to who's wearing them. If I were buying for myself — an adult who wants a light, foldable wired headphone for a laptop or tablet — I'd take the JVC HAS140P for its 3.2-ounce build and wider frequency range. But if I were buying for a young child heading to school or on a flight, I'd choose the noot products K11 without much hesitation: the 2-and-up fit, the 5 ft tangle-free cord, and the 24-month warranty are exactly what a kids' headphone should offer. Match the product to the person, and both make sense.
Yes. It's designed to fit children ages 2 and up with an adjustable headband that also fits most adults, and it pairs that with a 24-month warranty. The 5 ft tangle-free cord and foldable frame make it practical for school and travel.
The noot products K11 does not have a mic — you'd speak into the connected device instead. The JVC HAS140P doesn't list a microphone either. If hands-free calling is essential, neither is the right fit.
On paper, the JVC lists a wider range (20Hz–24,000Hz) versus the K11's 20Hz–20,000Hz, so the JVC reaches higher frequencies. Both are 32-ohm wired on-ear sets. "Better" ultimately depends on your ears and source, but the JVC has the broader stated range.
