How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a kid-safe pair of on-ear headphones with real active noise cancelling and a wired fallback for school or flights, choose JLab; if you need marathon battery life in a lightweight neckband you can top up straight from a phone or laptop port, choose Promise A12.
• JLab's biggest strength: it's built for children — on-ear plush comfort, three noise modes (ANC On, ANC Off, Be Aware) and a 3.5 mm jack so it still works when the battery dies.
• JLab's biggest trade-off: it's a kids' product with kid-sized positioning, and it's the heavier of the two at 8.8 ounces, so adults chasing all-day wear may find it bulky.
• Promise A12's biggest strength: up to 60 hours of playtime from a 280 mAh battery, plus a built-in Type-C adapter in the earbud cap so you charge it from almost any modern device without hunting for a cable.
• Promise A12's biggest trade-off: there is no active noise cancelling here — only passive isolation — and it's a neckband, not a headphone, so it's aimed at adults rather than children.
• Pick JLab if the listener is a kid, or if you want over-ear-style ANC and a wired option.
• Pick Promise A12 if the listener is an adult who wants long battery, a light neckband, and cable-free charging.
JLab's JBuddies ANC 2 in 1 is one of the few headphones in this comparison that was clearly designed around a child's head and a parent's peace of mind. The earcups are on-ear with a faux leather and plastic build, so the padding sits softly against the ear rather than pressing in, and the blue/red colorway signals immediately that this is a kids' product. At 8.8 ounces it has real substance, which is normal for something with an actual ANC circuit inside.
The feature that matters most here is the noise control. JLab gives you three modes: ANC On to block out loud environments like airplane cabins, ANC Off for normal listening, and Be Aware so a child can still hear traffic, a teacher, or a parent calling their name. That last mode is the one I'd want switched on for walking to school. The 50+ hour battery life means you're charging this maybe once a week in normal use, not every night.
Then there's the 2-in-1 part. A 3.5 mm jack is included alongside Bluetooth 5.3, so if the battery runs flat on a road trip, the headphones keep working with a cable. For a kid's product, that redundancy is genuinely useful — a dead pair of headphones on hour six of a drive is a bad afternoon for everyone.
Who should buy it: parents buying for a child roughly of school age and up, families who travel by plane or car, and anyone who wants ANC plus a wired backup in one package. The touch controls and 20 Hz–20,000 Hz dynamic drivers cover everyday music, audiobooks and schoolwork fine.
Who should skip it: adults who want a slim, discreet headphone for the office, and anyone who dislikes on-ear pressure or wants an in-ear fit. If you want a pair for yourself, this is the wrong shape and the wrong audience.
The Promise A12 takes the opposite approach. It's an in-ear neckband aimed squarely at adults — long-haul drivers, commuters, travelers, and anyone who resents charging a device every single day. The headline number is 60 hours of continuous music or talk time from a 280 mAh battery, with 200 hours of standby. In practice that means you could leave the charger at home for a week-long trip and still not think about it.
The genuinely clever bit is the built-in Type-C charging adapter. The earbud cap doubles as a Type-C plug, so you push the neckband straight into your phone, laptop or tablet and it charges — no cable required. I like this a lot for travel and for anyone who has ever arrived somewhere with a dead headset and no cable in the bag. A full charge takes about 2 hours.
Sound is handled by a balanced armature driver with a 20 Hz–20,000 Hz range, and you get three EQ modes: Bass for music, 3D Balance for general media, and Vocal for podcasts and calls. The microphone uses intelligent noise reduction for clearer voice on calls. One thing to be clear about, because Promise states it plainly: this is not Active Noise Cancelling. The noise control is passive only, so it muffles some background sound through the ear tip seal but won't cancel an engine drone the way ANC does.
Comfort is the other selling point. Skin-friendly silicone and flexible memory steel let the band sit around your neck without much weight, and magnets snap the two earbuds together when you take them out so they don't dangle or tangle. Bluetooth 5.3 with a roughly 10-metre range keeps the connection steady, and controls are simple push buttons rather than touch.
Side-by-Side: Which Should You Choose?
• Best for a child listener → JLab. The Be Aware mode, kid-focused build and on-ear padding are all designed for younger users.
• Best for battery life → Promise A12. Up to 60 hours versus JLab's 50+ hours, plus 200 hours of standby.
• Best for noise cancelling → JLab. It has genuine ANC with three modes; the A12 is passive isolation only.
• Best for travel charging convenience → Promise A12. The built-in Type-C adapter charges from a phone or laptop with no cable.
• Best for flights and loud environments → JLab. ANC On is made for exactly that scenario.
• Best for wired backup when the battery dies → JLab. The 3.5 mm jack keeps it usable; the A12 has no headphone jack.
• Best for all-day adult wear → Promise A12. The lightweight silicone-and-memory-steel neckband with magnetic buds is easier to forget about.
• Best for calls and podcasts → Promise A12. Vocal EQ mode plus a noise-reduction mic are tuned for voice, though JLab handles calls too.
• Best for shared listening → JLab. Its built-in cable and sharing-friendly design make it easier for two kids to listen together.
In my opinion, these two barely compete for the same buyer, so the decision is really about who's wearing them. If the listener is a kid, I'd buy the JLab JBuddies ANC 2 in 1 — the ANC, the Be Aware mode, the wired fallback and the sharing cable are exactly what a parent wants, and the two-year warranty backs it up. If the listener is an adult who wants to stop thinking about charging, I'd buy the Promise A12 — 60 hours, a built-in Type-C adapter and a light magnetic neckband solve a problem most earbuds don't. Buy for the person, not the spec sheet.
