• Oaxis myFirst Kids — biggest strength: An 85 dB safe volume cap plus a 21.5 g (0.76 oz) build, and an air conduction open-ear design that keeps kids aware of their surroundings.
• Oaxis myFirst Kids — biggest trade-off: It's a kids' product (ages 3–12) with passive noise cancellation only, so it isn't aimed at adult athletes or listeners who want deep isolation.
• SUNGDOGIN 2025 — biggest strength: Bone conduction drivers in a 29 g titanium frame, Bluetooth 5.4, IP55 water resistance, and up to 12 hours of playback with a built-in mic.
• SUNGDOGIN 2025 — biggest trade-off: It's squarely aimed at adults and it's heavier than the Oaxis, which matters for small heads.
• Who each pick is for: Oaxis myFirst Kids for parents buying for children; SUNGDOGIN 2025 for adult runners, cyclists, and commuters.
The myFirst Kids is built around one idea: protect young ears without cutting a child off from the world. The 85 dB volume cap is the headline here — it's a designed ceiling, not a suggestion, which is why it's aimed at ages 3–12. If your kid uses headphones for tablet time, online classes, audiobooks, or long car and plane rides, that cap is the whole point.
The air conduction, open-ear design means sound reaches the ear without plugging it. Kids can still hear traffic, a parent calling their name, or a coach on the playground. That's a meaningful difference from over-ear cans that seal a child off. At 21.5 g it's genuinely light — you can see why the spec sheet calls out "no ear pain" and pressure-free fit for small ears. IPX5 water resistance covers sweat, splashes, and typical outdoor roughness.
What it does best: kid-appropriate volume safety, all-day comfort, and environmental awareness. Buy it if you're a parent who wants a wireless headphone a child can wear for school, travel, and outdoor play without you hovering. Skip it if you're an adult looking for a sports headset — the fit, sizing, and feature set are tuned for children, not grown-ups. Battery is rated at 18 hours, and the box includes a cable, user manual, and stickers for customization.
The SUNGDOGIN 2025 is an adult sports headset that uses bone conduction rather than air conduction. Sound travels through the cheekbones, which leaves the ear canal completely open — the same awareness benefit as the Oaxis, but delivered through a different mechanism. The fully enclosed cavity design is claimed to reduce sound leakage by up to 50%, which is the kind of detail that matters if you listen in quiet spaces or on calls.
The frame is titanium and weighs 29 g. Titanium is the interesting choice: it's flexible and durable, so it can be stretched and bent without deforming — exactly what you want from something you wear running, hiking, or cycling. IP55 water resistance handles sweat and rain spray. Bluetooth 5.4 is the newer wireless standard, and there's a built-in mic with noise cancellation for calls and video conferences.
What it does best: long single-charge listening (up to 12 hours), rugged sports-friendly construction, and clear hands-free calling. Buy it if you're an adult who runs, cycles, walks, or takes a lot of calls and wants your ears open the whole time. Skip it if you're shopping for a young child — this is listed for adults, and the 29 g weight and hook-style fit are designed for grown-up head shapes. The box includes a cable, eartip, and user manual.
• Best for young children → Oaxis myFirst Kids. The 85 dB cap and 21.5 g weight are purpose-built for ages 3–12.
• Best for adult sports → SUNGDOGIN 2025. Titanium frame, IP55, and a hook-style open-ear fit for running and cycling.
• Best for lighter weight → Oaxis myFirst Kids at 21.5 g versus 29 g for the SUNGDOGIN.
• Best for longer playback → Oaxis myFirst Kids at 18 hours versus 12 hours for the SUNGDOGIN.
• Best for calls and meetings → SUNGDOGIN 2025. It has a built-in mic with noise cancellation; the Oaxis sheet doesn't list a mic.
• Best for durability under bending → SUNGDOGIN 2025. The titanium frame is designed to flex without deforming.
• Best for hearing protection by design → Oaxis myFirst Kids. The 85 dB limit is the feature, not a side effect.
• Best for newer wireless standard → SUNGDOGIN 2025 with Bluetooth 5.4 versus Bluetooth 5 on the Oaxis.
If I were buying for a child between 3 and 12, I'd pick the Oaxis myFirst Kids without much hesitation. The 85 dB cap, the 21.5 g weight, and the IPX5 rating line up exactly with how kids actually use headphones — school, travel, and outdoor play. In my opinion the volume ceiling alone justifies it for a parent. If I were buying for myself as an adult runner or commuter, I'd take the SUNGDOGIN 2025: the titanium frame, IP55 rating, Bluetooth 5.4, and built-in mic fit that life better. Two different jobs, two different answers.
how to wear air conduction headphones
Air conduction headphones like the Oaxis myFirst Kids rest outside the ear rather than inside it, so sound reaches the ear without blocking the canal. Place the earpieces so they sit lightly against or just outside the ear opening, then adjust until they feel pressure-free. The open design is deliberate — it's what lets your child still hear surrounding sounds.
how to use air conduction headphones
Power them on, pair over Bluetooth, and use the one-touch button controls to play, pause, and adjust volume. The myFirst Kids uses button and touch controls on the headset itself. Keep the volume at a comfortable level — on the Oaxis the 85 dB cap handles that ceiling for you.
how to put on air conduction headphones
Slide the headset into place so the open-ear earpieces sit outside the ear canal, not jammed into it. The Oaxis is designed for a secure, pressure-free fit for small ears at 21.5 g, so it should feel barely there. If it pinches, reposition rather than pushing harder.
how to pair goodmans air conduction headphones
The general Bluetooth steps apply to any brand, including these two: turn the headphones on, put them in pairing mode, open Bluetooth settings on your phone or tablet, and select the device. The Oaxis uses Bluetooth 5 with roughly a 10-meter range; the SUNGDOGIN uses Bluetooth 5.4. If pairing fails, turn the headphones off and on and try again.
