How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a volume-capped pair built specifically for young kids, choose JBL Junior 320; if you need a two-pack of Lightning earbuds for an iPhone with no headphone jack, choose wamaxlink Apple MFi Certified.
• JBL Junior 320's biggest strength: JBL Safe Sound caps output at 85dB, so a child can't accidentally crank the volume into hearing-damage territory.
• JBL Junior 320's biggest trade-off: It's a single pair of on-ear kids' headphones with a 3.5mm jack, so it won't plug into a Lightning-only iPhone without an adapter.
• wamaxlink Apple MFi Certified's biggest strength: It's a two-pack of in-ear earbuds with a Lightning plug, built to work with iPhone 14/13/12/11 Pro Max and older Lightning models.
• wamaxlink Apple MFi Certified's biggest trade-off: The Lightning connector limits it to Apple devices with that port, and there's no volume ceiling for young ears.
• Pick JBL Junior 320 if the listener is a kid using a tablet, laptop, school device or anything with a standard headphone jack.
• Pick wamaxlink Apple MFi Certified if you want a spare-pair setup for iPhone users who want wired earbuds with a mic and remote.
JBL Junior 320 is a wired on-ear headphone with one job above all others: keeping volume safe for kids. The headline feature is JBL Safe Sound, which the spec sheet says is designed to never exceed 85dB. That single number is the whole reason this product exists. Parents who worry about a child sliding the volume slider all the way up get a hard ceiling instead of a warning label.
Around that core, JBL built a genuinely kid-oriented package. The headband has a 12mm padded section and adjusts to fit a growing head. The earcups are round and on-ear, which the sheet describes as giving better grip and less sound leakage — useful when a kid is moving around rather than sitting still. The 32mm dynamic drivers cover a 20Hz–20kHz range at 34 ohm impedance, so it's a normal, easy-to-drive headphone that any phone, tablet or laptop jack can power.
The rest is practical parenting. It folds flat, so it disappears into a backpack. There's a built-in mic and a remote with buttons, so a kid can talk to a teacher during a lesson or call a grandparent. The set ships with a sticker pack, which matters more than adults think — a kid who personalizes their headphones is a kid who takes care of them. It's rated for ages listed simply as "Kid," weighs about 117g, and carries a 1-year manufacturer warranty.
Who should buy it: parents of younger children, especially for school, travel and car rides, or anyone buying a first "real" headphone for a kid with a 3.5mm device. Who should skip it: adults who want serious sound quality, anyone with a Lightning-only iPhone and no adapter, and anyone who needs more than one pair in the box.
wamaxlink Apple MFi Certified is solving a completely different problem: the modern iPhone has no headphone jack, and a lot of people still want wired earbuds. This set uses a Lightning connector, which the spec sheet lists as the jack type, and it's aimed at iPhone 14, 13, 12, 11 Pro Max, XS, XR, X, 8, 7 and SE owners. If your phone still has a Lightning port, this plugs straight in. There's no Bluetooth pairing, no charging case, no battery to think about — the sheet calls it "true plug and play," and that's the honest pitch.
The earbuds are in-ear with a white ABS housing, and they include a built-in mic plus a remote with a defined button scheme: one press for play/pause, two presses for next track, three for previous track. That's a real convenience if you take calls or skip songs while walking. The description also emphasizes noise reduction for calls and music in loud environments, and a dual sound-hole design the brand describes as 360° surround tuning.
Two details stand out in the spec sheet. First, it's a 2-pack — you get two sets of earbuds, which is the obvious move for anyone who loses earbuds constantly or wants one pair for home and one for a bag. Second, the age range is listed as Adult, and the warranty is listed as 36 months with 24/7 customer service, which is a longer coverage window than most budget earbuds bother to advertise.
Who should buy it: iPhone users on a Lightning port who want cheap, no-fuss wired earbuds with a mic and remote, and anyone who wants a backup pair in the drawer. Who should skip it: anyone with a USB-C iPhone, an Android phone, a laptop or a kids' tablet — none of those have a Lightning jack, so this set simply won't connect.
• Best for child hearing safety → JBL Junior 320. The 85dB cap is the deciding spec; there is no equivalent limit on the wamaxlink set.
• Best for iPhone users with a Lightning port → wamaxlink Apple MFi Certified. The Lightning connector is the only way it connects.
• Best for non-Apple devices → JBL Junior 320. A 3.5mm jack works with tablets, laptops, school Chromebooks, handheld consoles and older phones.
• Best for getting two pairs → wamaxlink Apple MFi Certified. It ships as a 2-pack; JBL Junior 320 is one headphone plus a sticker set.
• Best for long-wear comfort on a small head → JBL Junior 320. The 12mm padded, adjustable headband and round on-ear cups are built around that fit.
• Best for on-the-go calls and track skipping → wamaxlink Apple MFi Certified. The remote's one/two/three-press control scheme covers play, pause and track changes.
• Best for durability coverage → wamaxlink Apple MFi Certified on paper, with a listed 36-month warranty versus JBL's 1-year manufacturer warranty.
• Best for travel and packing → JBL Junior 320 for kids' trips, since it folds flat; wamaxlink wins for pocket carry as in-ear buds.
On the "wired headphones" question specifically, both are wired, but they're wired into different worlds. The JBL uses the universal analog 3.5mm standard — the one that works almost everywhere. The wamaxlink uses Lightning, which is a digital Apple-specific connector. That one difference decides most buyers before anything else does.
In my opinion, the choice comes down to who's wearing them. If this is for a child, I'd buy the JBL Junior 320 — the 85dB limit, the adjustable padded headband, the foldable build and the 3.5mm jack make it the safer, more versatile pick for a kid's school bag and travel kit. If this is for an adult on an iPhone with a Lightning port, I'd buy the wamaxlink Apple MFi Certified instead, mainly because you get two pairs, a mic and remote, and a listed 36-month warranty. Neither is a compromise for the other's user — they just aren't competing for the same person. Check the current price on Amazon before you decide, since that's the one variable I can't weigh for you.
how to wired headphones work
A wired headphone passes an analog or digital audio signal from your device straight down the cable to the drivers, which convert it into sound. JBL Junior 320 uses a 3.5mm analog jack, so any device with that port can drive it. wamaxlink Apple MFi Certified uses a Lightning connector, so the signal comes digitally from an Apple device only.
how to use wired headphones with iphone
If your iPhone has a Lightning port, plug Lightning earbuds like wamaxlink Apple MFi Certified straight in — no pairing needed. If your iPhone has no headphone jack and you're using a 3.5mm headphone like JBL Junior 320, you need a Lightning-to-3.5mm adapter. Newer USB-C iPhones need a USB-C adapter instead, which rules out the wamaxlink set.
how to fix wired headphones no sound
Start with the connection: unplug and reseat the jack, and check that the plug is fully inserted. Then test the headphones on a second device to work out whether the fault is the headphone or the port. On the wamaxlink set, also check the remote's play/pause button hasn't been pressed into a paused state.
are wired headphones better than wireless
Wired sets need no charging and no pairing, which is exactly why both of these exist. JBL Junior 320 also adds an 85dB volume cap for kids, and wamaxlink Apple MFi Certified gives you a mic and remote over Lightning. Wireless wins on freedom of movement; wired wins on simplicity.
