If you want a safer, parent-minded pair of open-ear headphones built specifically for young children, choose Oaxis myFirst Kids; if you need lightweight clip-on earbuds for your own running and workouts, choose Wiykasenbos Open Ear. These two look similar on paper because both use air conduction to keep your ears open, but they are aimed at completely different people.
• Oaxis myFirst Kids — biggest strength: An 85 dB volume cap plus a tiny 0.76 oz (21.5 g) frame, a 10 m Bluetooth range, and up to 18 hours of battery, all designed for kids ages 3–12.
• Oaxis myFirst Kids — biggest trade-off: It is a kids' product first, so the audio and control set are simple rather than feature-packed for adult listeners.
• Wiykasenbos Open Ear — biggest strength: Bluetooth 5.3, a 13 mm driver, and a clip-on fit that stays put during sports, with IPX5 sweat resistance.
• Wiykasenbos Open Ear — biggest trade-off: About 5 hours of playback per charge and a 5-hour charge time, so it expects frequent top-ups.
• Who each pick is for: Oaxis myFirst Kids is for parents buying for a child; Wiykasenbos Open Ear is for an adult who wants open-ear audio while training.
The myFirst Kids Headphones AirWaves are built around one idea: a child should be able to listen without you worrying about their ears. The headline feature is the 85 dB volume cap, which limits how loud the headphones can go. For a parent, that single design choice answers the biggest question about any pair of kids' headphones. It also lines up with the impedance (32 ohm) and sensitivity (85 dB) figures listed for the model, so the whole audio chain is tuned for a gentler output rather than maximum loudness.
The second thing that stands out is how light they are. At 0.76 oz (21.5 g), these are about as light as kids' headphones get, and the open-ear air conduction design means nothing presses into the ear canal. For a child on a long car ride, a flight, or a full school day, that matters more than any spec sheet number. The IPX5 rating means sweat and splashes from the playground or a bike ride are not a problem, and the open-ear fit keeps them aware of traffic and voices around them.
Battery is listed at 18 hours of average life, charged over Type-C, and the controls are simple one-touch buttons rather than touch surfaces, which is the right call for small hands. You also get stickers for personalization, plus a carrying case, cable and manual in the box. Bluetooth 5 keeps the wireless connection straightforward within roughly 10 meters.
So who should buy it? Parents of kids roughly 3 to 12 who want a safe volume ceiling, a featherweight fit, and a pair that survives outdoor play. Who should skip it? Adults who want strong bass, long battery for all-day work, or advanced controls. This is a child's headphone, and it is honest about that.
The Wiykasenbos Open Ear is a different animal. It is a pair of clip-on earbuds with a charging case, aimed squarely at running and workouts. The design brief is clear from the feature list: open listening so you can hear your surroundings while you move, which is a genuine safety point for anyone running near traffic or cycling.
The spec that stands out most is Bluetooth 5.3, which is a newer wireless standard than the Bluetooth 5 on the Oaxis pair. In practice that generally means a smoother, more stable connection, and Wiykasenbos leans into that with a built-in HD microphone for calls. The audio hardware is a 13 mm coated biofilm moving coil driver with a frequency range of 20 Hz to 20,000 Hz, and the listed driver type is a bone conduction driver, so the low end and detail should be more substantial than a basic kids' headphone.
The clip-on ear hook design is the other selling point. Ear clip earbuds are meant to stay put, which is exactly what you want when you are moving. IPX5 water resistance covers sweat, and the controls are touch-based media controls rather than physical buttons.
The trade-off is battery. Single-charge life is listed at 5 hours, and charge time is also 5 hours. For a workout or a run, that is fine. For a full workday of continuous listening, it is not, and you will need to think about the charging case as part of your routine. It is also listed for adults, with no volume cap and no kid-focused design.
Buy it if you are an adult who wants open-ear audio for training, calls and movement, and you value the newer Bluetooth version. Skip it if you need marathon battery life or you are shopping for a young child.
• Best for young children (ages 3–12) → Oaxis myFirst Kids, because of the 85 dB volume cap and the kid-specific build.
• Best for running and workouts → Wiykasenbos Open Ear, thanks to the clip-on fit, IPX5 sweat resistance, and sports-first design.
• Best for battery life → Oaxis myFirst Kids, with up to 18 hours of average life versus about 5 hours on the Wiykasenbos.
• Best for charging speed → Oaxis myFirst Kids, since it lists Type-C fast charging while the Wiykasenbos lists a 5-hour charge time.
• Best wireless spec → Wiykasenbos Open Ear, with Bluetooth 5.3 against Bluetooth 5.
• Best for calls → Wiykasenbos Open Ear, which lists a built-in HD microphone and Bluetooth 5.3 for smoother voice pickup.
• Best for the lightest fit → Oaxis myFirst Kids at 0.76 oz (21.5 g), though the Wiykasenbos clip-on design is also built to stay secure.
• Best for gift-giving to a child → Oaxis myFirst Kids, which ships with stickers, a carrying case, and a cable.
In my opinion, the right buy depends entirely on who is wearing them, and that is the honest answer here. If I were buying for a child, I would buy the Oaxis myFirst Kids without hesitating: the 85 dB cap, the 0.76 oz build, the 18-hour battery and the simple button controls are exactly what a parent should want, and the open-ear design keeps a kid aware of their surroundings. If I were buying for myself for running, I would take the Wiykasenbos Open Ear instead, because Bluetooth 5.3, the 13 mm driver, the HD mic and the clip-on fit are built for movement in a way the kids' model is not. Two different jobs, two different winners.
how to wear air conduction headphones
Air conduction headphones sit outside your ear canal rather than inside it, so the sound reaches your ear through the air while your canal stays open. On the Oaxis myFirst Kids, the open-ear frame rests lightly over the ear; on the Wiykasenbos Open Ear, the clip-on hook loops over the ear and holds the bud in place. In both cases, you should still hear voices and traffic around you.
how to use air conduction headphones
Pair them over Bluetooth first, then use the onboard controls for playback. The Oaxis myFirst Kids uses one-touch button controls for play, pause and volume, while the Wiykasenbos Open Ear uses touch-based media controls. Because both are open-ear designs, keep the volume at a level where you can still hear what is happening around you.
how to put on air conduction headphones
Place the earpiece so the driver sits just outside the ear opening, not pushed into the canal. The Oaxis myFirst Kids is a lightweight over-ear fit at 0.76 oz (21.5 g), so it simply rests in position. The Wiykasenbos Open Ear is a clip-on design, so you hook it over the ear and let the clip hold it steady, which is why it is described as not easy to fall off.
how to pair goodmans air conduction headphones
If you are pairing a different open-ear model such as a Goodmans pair, the process is the same as these two: turn the headphones on, put them in pairing mode, then select them from your phone's Bluetooth list. The Oaxis myFirst Kids uses Bluetooth 5 and the Wiykasenbos Open Ear uses Bluetooth 5.3, both with a listed range of about 10 meters, so keep your device close during the first connection.
