If you want a wired kids' headphone built for sharing between two children on one device, choose LilGadgets Connect+ Pro; if you need a wired kids' headphone with an adjustable 85/94dB volume limit and a mic tuned for calls and online classes, choose EarFun K3.
• LilGadgets Connect+ Pro — biggest strength: integrated SharePort technology lets you daisy-chain multiple headphones to a single device with no splitter, plus a foldable polycarbonate build with metal extenders and a detachable cable.
• LilGadgets Connect+ Pro — biggest trade-off: it is a kids-first, 93dB-limited over-ear, so it is not aimed at adults who want an adjustable or higher output ceiling.
• EarFun K3 — biggest strength: a switchable 85/94dBA volume limit and a built-in HD microphone with call control, which suits online classes and voice chat.
• EarFun K3 — biggest trade-off: no share port, so two kids on one tablet means a separate splitter, and there is no named folding hardware beyond its foldable design.
• Who each is for: LilGadgets Connect+ Pro is for families with two or more kids sharing one device; EarFun K3 is for a single child who needs a mic for school calls and travel.
The Connect+ Pro is a wired over-ear headphone for kids aged 6 and up, and the whole design reads like it was drawn around one problem: two kids, one tablet, one audio jack. Its SharePort technology lets you plug additional headphones into the first pair so everybody hears the same thing without hunting for a splitter. If you have ever refereed an argument over whose turn it is to hold the iPad, that single feature is the reason this pair exists.
The build is aimed at kids who are hard on gear. The housing is high-quality polycarbonate reinforced with stainless steel extenders for variable sizing, wrapped in SoftTouch fabric padding, and the cable is detachable — which matters, because the cable is usually the first thing to fail on a kids' headphone. It folds for storage and ships with a travel pouch. The 40mm dynamic drivers cover a 20Hz–20kHz range at 32 ohms (listed at 30 ohms in the item details), and output is volume limited to 93dB with passive noise reduction from the over-ear seal.
The trade-off is that 93dB is the ceiling, full stop. There is no 85dB setting for a younger or more sensitive child, and no adjustable limiter. It is also explicitly a kid product in styling and fit, so an adult looking for a cheap wired desk headphone will find it small and capped. In my opinion, buy it if sharing is your main headache. Skip it if you need a mic you can switch between call and class modes or a lower volume tier for a five-year-old.
The EarFun K3 is also a wired over-ear kids' headphone with 40mm dynamic drivers and a 20Hz–20kHz frequency range at 32 ohms, but it solves a different set of problems. The headline feature is the 85/94dBA volume limit — two tiers, so you can set a stricter cap for a younger child and open it up for an older one. That flexibility is the single biggest functional difference between these two headphones, and for a lot of parents it is the deciding one.
The second differentiator is the built-in HD microphone with call control on a button remote. The cord carries a remote, so a kid can take a call or join a class without grabbing the tablet. EarFun positions it for school and travel, and the soft parts — plastic, leather and metal in the enclosure — plus a 180g weight suggest something light enough to wear through a lesson. It folds, and EarFun backs it with an 18-month warranty.
Where it gives ground is sharing. There is no pass-through port, so a second listener needs a splitter. It also lists no active noise cancellation, just the natural isolation of an over-ear fit, and the sensitivity figure is unusually high at 110dB, which is worth understanding: sensitivity is how loud the driver gets per unit of input, not the output ceiling, and the 85/94dBA limiter is what actually caps what reaches your child's ears. So don't read that number as "louder than the LilGadgets" — the limiter governs. In my opinion, this is the pick for one child with a school-issued device and a call schedule. Skip it if two kids routinely share a screen.
• Best for sharing one device between kids → LilGadgets Connect+ Pro, thanks to SharePort with no splitter required.
• Best for adjustable volume safety → EarFun K3, with its switchable 85/94dBA limit versus the Connect+ Pro's fixed 93dB cap.
• Best for online classes and calls → EarFun K3, which pairs an HD built-in mic with button call control.
• Best for durability against rough handling → LilGadgets Connect+ Pro, with a polycarbonate shell, stainless steel extenders and a detachable cable.
• Best for travel storage → a tie on paper: both fold and both are aimed at school and travel use, though only the Connect+ Pro lists a travel pouch in the box.
• Best for a younger child → EarFun K3, because the 85dB tier gives you a stricter setting the Connect+ Pro simply does not have.
• Best for a mixed-age household → EarFun K3 on the volume tiers, unless the kids share screens, in which case the Connect+ Pro wins.
• Best for weight → EarFun K3 at 180g, though the Connect+ Pro's SoftTouch padding is the comfort story on the other side.
If two children in your house fight over one tablet, I would buy the LilGadgets Connect+ Pro. SharePort is not a gimmick — it removes the splitter, the missing adapter and the "it's not working" meltdown in one move, and the metal extenders plus detachable cable are the right choices for gear that lives in a backpack.
If you have one child who needs a headphone for school calls, online classes and travel, I would buy the EarFun K3 instead. The 85/94dBA switch and the built-in mic with call control cover the two things that actually come up in a school week, and the 18-month warranty adds peace of mind. My honest read: sharing is a LilGadgets problem, and classroom calling is an EarFun problem. Pick the one that matches your week. Either way, check the current price on Amazon before you commit — both brands change their listings over time.
how to wired headphones work
A wired headphone turns an electrical audio signal from your device into sound through its drivers. The 3.5mm jack carries that signal down the cord, and the drivers — 40mm dynamic drivers on both the Connect+ Pro and the K3 — convert it into the sound you hear. Because the cable also supplies the connection, there is no battery or pairing step involved.
how to use wired headphones with iphone
Plug the 3.5mm jack into your iPhone if it has a headphone jack; on newer iPhones with only a Lightning or USB-C port you need the matching adapter. Both the Connect+ Pro and the EarFun K3 are listed as compatible with iOS and Android devices in their respective spec sets, and both use a standard 3.5mm jack. Once connected, the EarFun K3's inline remote handles call control directly.
how to fix wired headphones no sound
Start at the jack: unplug it, check for lint or debris in the port, and reseat it firmly. Then check the cable along its length — a detachable cable like the one on the Connect+ Pro can be swapped or reseated, which is a real advantage when the cord is the failure point. Finally, test the headphones on a second device to confirm whether the problem is the headphone or the source.
do wired headphones work without a battery
Yes. A passive wired headphone draws its signal from the connected device, so there is nothing to charge. Both the LilGadgets Connect+ Pro and the EarFun K3 are wired 3.5mm designs, and neither relies on a battery to produce sound — which is exactly why they suit kids who would otherwise forget to charge something.
