• Oaxis myFirst Kids — biggest strength: a hard 85 dB volume cap plus a genuinely tiny 21.5 g build, so parents get hearing protection and kids get all-day comfort.
• Oaxis myFirst Kids — biggest trade-off: it's tuned for ages 3–12, so adults and serious athletes will find the fit and the volume ceiling limiting.
• IHAO Air Conduction — biggest strength: Bluetooth 5.2, a sweatproof IPX5 shell and a secure 46 g fit aimed squarely at intense movement.
• IHAO Air Conduction — biggest trade-off: no volume limiting and no stated battery figure, and it's listed for adults only.
• Who each pick is for: Oaxis myFirst Kids is for parents buying safe headphones for study and school; IHAO Air Conduction is for adult runners, cyclists and gym-goers.
The myFirst Kids is, first and foremost, a hearing-safety product that happens to be a headphone. The 85 dB volume cap is the headline spec, and it's the reason this exists: it keeps music, online classes and audiobooks at a level that's considered safer for young ears. For a parent whose kid is doing schoolwork on a tablet or sitting through a long car ride, that one number removes the constant "turn it down" argument. The 20 Hz–20,000 Hz dynamic driver handles the full audible range, so nothing sounds thin — you're just not getting a hearing-damaging ceiling.
The second thing that stands out is the weight: 21.5 g (0.76 oz). That is remarkably light, and the open-ear air conduction design means nothing is jammed into the ear canal, so there's no pressure build-up over a long study session. The IPX5 rating means sweat and splashes from the playground aren't a problem, and the one-touch button controls are simple enough that a young kid can play, pause and adjust volume without help. Charging is USB Type-C, and there's a fun sticker sheet for personalization — a small thing, but it matters when you're handing a device to a seven-year-old.
Where it falls short: the listed battery average life is 18 hours, which is solid for a kid's day but not class-leading, and the Bluetooth 5 spec with a 10-meter range is fine but not the newest. More importantly, it's explicitly a kids' product for ages 3–12. If you're an adult looking for sport headphones, the volume cap and the small fit will frustrate you. Skip it if you want open-ear earbuds for your own study or workouts — this one isn't aimed at you.
The IHAO F806 is built for movement. The open-ear design rests on the cheekbones rather than inside the ear, which keeps you aware of traffic, other runners and gym surroundings — the classic argument for air conduction. Bluetooth 5.2 gives you a more current wireless connection than the myFirst Kids' Bluetooth 5, and the brand states it's tuned for stable playback and clear calls, which matters if you take a call mid-run or mid-workout.
It's also the tougher of the two on paper: IPX5 waterproofing handles sweat and rain, and the roughly 46 g frame is described as staying secure through running, cycling and gym work. The 20 Hz–20,000 Hz range matches the Oaxis, and it's listed as an adult product (no age restriction on young ears here), so there's no volume cap to fight against.
The trade-offs are real, though. There's no stated battery life at all, which is the biggest blank on the sheet — if long sessions matter to you, that's an unknown you'll want to check before buying. There's no noise control listed of any kind, and the audio driver is described as a bone-conduction driver, which is an odd detail on a product marketed as air conduction. It's also the heavier of the two at roughly double the weight, and there's no volume limiting, so it's not a child-safety product. Skip it if you're buying for a young kid or you want a guaranteed safe listening ceiling.
Side-by-Side: Which Should You Choose?
• Best for study with a young child → Oaxis myFirst Kids. The 85 dB cap and 21.5 g fit are made for long, quiet sessions at a desk or on a tablet.
• Best for hearing safety → Oaxis myFirst Kids. It's the only one of the two with a stated volume limit.
• Best for newer Bluetooth → IHAO Air Conduction. Bluetooth 5.2 versus Bluetooth 5 on the Oaxis.
• Best for all-day comfort on small heads → Oaxis myFirst Kids. 21.5 g is about half the weight of the IHAO's ~46 g.
• Best for guaranteed battery figures → Oaxis myFirst Kids. It lists 18 hours; the IHAO sheet states no battery life.
• Best for calls during workouts → IHAO Air Conduction. Bluetooth 5.2 and a built-in-position mic design for clear calls.
• Best for kids ages 3–12 → Oaxis myFirst Kids, full stop. The IHAO is listed for adults.
For the study use case this article is built around — a kid doing homework, online classes or audiobooks — I'd buy the Oaxis myFirst Kids. The 85 dB volume cap is the single most useful feature here, and at 21.5 g with an 18-hour battery and IPX5, it covers a full school day comfortably. In my opinion it's the more responsible buy for a child, and the one-touch controls and Type-C charging keep it easy for both kid and parent. I'd pick the IHAO Air Conduction only if I were the one wearing them — an adult runner or cyclist who wants Bluetooth 5.2, a sweatproof shell and a secure sport fit, and who doesn't need a volume ceiling. Check the current price on Amazon before you decide, since that's the one variable I can't weigh for you.
how to wear air conduction headphones
Air conduction headphones rest outside your ear canal rather than inside it. On the myFirst Kids and the IHAO F806, the earpieces sit against the area near your cheekbone, leaving the ear opening clear so you can still hear your surroundings. Position them so the driver points toward your ear without pressing in.
how to use air conduction headphones
Power them on, pair over Bluetooth, then use the on-device controls for play, pause and volume. The Oaxis myFirst Kids uses simple one-touch button controls and charges over USB Type-C; the IHAO F806 pairs over Bluetooth 5.2. Keep the volume at a comfortable level — and with the Oaxis, the 85 dB cap handles that for you.
how to put on air conduction headphones
Slide the band or hook over your ears so the drivers sit just in front of the ear opening, not inside it. The Oaxis weighs only 21.5 g, so it should feel almost weightless; the IHAO is around 46 g and is designed to stay put during running or cycling. Adjust until the fit is snug but not pressing.
how to pair goodmans air conduction headphones
Goodmans is a different brand from both Oaxis and IHAO, so I can't give you pairing steps for it from these specs. The general method is the same across air conduction models: put the headphones in pairing mode, open your phone's Bluetooth settings, and select the device. For the exact button sequence on a Goodmans model, follow that brand's own instructions.
