How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a featherweight pair of in-ear buds you can tuck into a shirt pocket and forget about while you're waiting for a bite, choose JVC HAF160B; if you need a kid-safe, over-ear wired headset with a microphone for school, travel or calls, choose EarFun K3. That's the short version, and it stays true whether you're packing a tackle box for fishing or a backpack for the school run.
• JVC HAF160B biggest strength: 5 g of rubber-tipped in-ear design with a 3.5 mm jack and 16 ohm impedance — the kind of low-fuss corded headphone you can wear for hours without noticing it.
• JVC HAF160B biggest trade-off: no microphone and no volume limiter, so it's a listening-only tool rather than a communication one.
• EarFun K3 biggest strength: a 40 mm dynamic driver, a built-in HD mic and an 85/94 dBA volume limit, all in a folding over-ear shell.
• EarFun K3 biggest trade-off: 180 g on your head and a kids-first design brief — it's not trying to be a discreet everyday earbud.
• Choose JVC HAF160B if you want something tiny, wired and pocketable for music, podcasts or a quiet hour by the water.
• Choose EarFun K3 if you want a headset a child can wear safely, talk through and fold away.
The HAF160B is about as simple as corded audio gets, and that's the appeal. You get a 3.5 mm jack, a wired connection, a 16 ohm impedance rating and a 15 Hz – 20 kHz frequency range driven by a dynamic driver. Sensitivity is listed at 108 dB, which tells you it doesn't need much of a push to get loud. The enclosure is rubber, the ear placement is in-ear, and the tips are rounded — a shape that tends to sit quietly in the ear rather than clamp onto it.
At 5 g, this is a headphone you genuinely forget you're wearing. For anyone who wants in-ear headphones for fishing, that matters: long stretches of standing, casting and waiting are exactly when a bulky headset becomes annoying. A light bud with a cord that runs to a phone in a pocket is the least distracting way to listen. The controls are listed as volume control with a touch method, so basic adjustment is handled on the bud itself.
Who should skip it? Anyone who needs to talk. There is no microphone here, no volume ceiling for a child, and no call control. The noise control field is listed as "none," so this is not a noise-cancelling product and shouldn't be bought as one. If your use case is online classes, phone calls or a young kid's first headset, this isn't the tool — the EarFun K3 is built precisely for that. The HAF160B is for the person who wants one small, wired, low-impedance pair of buds and nothing more.
The K3 is a different animal entirely, and the spec sheet says so before you even look at the name. This is an over-ear headphone with a 40 mm dynamic driver, 32 ohm impedance, 110 dB sensitivity and a 20 Hz – 20 kHz range. The shell mixes plastic, leather and metal, and it folds for storage. It weighs 180 g, which is normal for an on-ear style and roughly 36 times the HAF160B — a number worth sitting with if portability is your priority.
The headline features are the two that matter to parents. First, the 85/94 dBA volume limit, which caps output so a child's ears aren't exposed to damaging levels — you keep a usable balance between safety and sound. Second, the built-in HD microphone, which turns the K3 into a two-way device for calls and online classes rather than a one-way listening tool. There's also a listed audio latency of 20 ms, which is relevant if a kid is watching video or playing a game and you'd rather the audio didn't drag behind the picture.
Who should buy it? Families, basically. If you're shopping for the best on-ear headphones for fishing with a kid in tow — or more realistically, for a child who needs something for school, a tablet, an iPad or a long car ride — the K3 covers the practical checklist: mic, volume limit, folding frame, 3.5 mm jack. The theme listing (cartoon, fantasy, movie, TV series, video game) tells you who the design is aimed at, and the purple colorway fits that brief.
Who should skip it? Adults who want a discreet, near-weightless bud. The K3 is visible, it's on your head, and it's built around a child's needs. If you don't need a mic or a volume cap, you're paying in weight and bulk for features you won't use. It's also worth noting the warranty is listed at 18 months, which is a reasonable safety net for a kids' product that will get folded, dropped and stuffed into bags.
Side-by-Side: Which Should You Choose?
• Best for calls and online classes → EarFun K3. The HAF160B has no microphone at all; the K3 has a built-in HD mic and call control.
• Best for young listeners → EarFun K3. The 85/94 dBA volume limit is the feature that decides this category.
• Best for a pocketable backup pair → JVC HAF160B. Rounded rubber tips, in-ear fit, 3.5 mm jack, tiny footprint.
• Best for video and gaming with a child → EarFun K3. The 20 ms listed latency plus the 40 mm driver suits screen time better than a bare bud.
• Best for easy driving from a phone → JVC HAF160B. At 16 ohm it's the lower-impedance design of the two; the K3 sits at 32 ohm.
• Best for durability against kids → EarFun K3. A foldable over-ear frame with leather and metal in the build is more forgiving of rough handling than tiny rubber buds.
• Best for simplicity → JVC HAF160B. Wired, in-ear, volume control, done. Nothing to configure.
In my opinion, the right pick depends entirely on who's wearing them, and the spec sheets make that split unusually clean. If I were buying for myself — something to keep in a jacket pocket for music while fishing, or for quiet listening anywhere — I'd take the JVC HAF160B. It's 5 g, it's in-ear, it's wired, and it does one job without asking anything of me. If I were buying for a child who needs to talk in class, join a call or watch a tablet safely, I'd take the EarFun K3 without hesitating: the mic and the 85/94 dBA volume limit are exactly the two features a kids' headset should have. Two different buyers, two different answers.
FAQ
how to wired headphones work
A wired headphone takes the analog audio signal from your device through the 3.5 mm jack and drives a dynamic driver inside the earcup or bud. The JVC HAF160B uses a 16 ohm dynamic driver; the EarFun K3 uses a 40 mm dynamic driver at 32 ohm. No battery or pairing is involved on either — the cord carries both the signal and the power.
Plug the 3.5 mm jack into your phone or into an adapter your phone requires, then set volume on the device. Both the HAF160B and the K3 use a standard 3.5 mm jack, so neither needs pairing or charging. The K3 adds a built-in microphone and call control, so it can also handle calls once connected.
how to fix wired headphones no sound
Start with the simple checks: confirm the jack is fully seated, try a different device, and make sure the volume isn't at zero. Because both of these are passive wired designs with no battery, a dead battery is never the cause. If one side only works when you wiggle the plug, the cable or jack connection is usually the culprit.
how to wired headphones for fishing
For fishing, the practical concerns are weight, fit and whether you need to talk. The JVC HAF160B at 5 g with rounded in-ear tips is the lighter, less intrusive option for listening while you wait. The EarFun K3 is over-ear and heavier at 180 g, but it adds a mic — useful if you take calls on the bank rather than just listening.
