How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want open-ear headphones for your own runs, rides and workouts with a full-size speaker and a sweat-and-rain-proof build, choose Soynoen Bone Conduction Headphones; if you need safe, volume-capped open-ear audio for a child with parental controls and all-day battery, choose Giznity Kids.
• Soynoen Bone Conduction Headphones — biggest strength: bone conduction sound through a 16.2 mm driver with a titanium alloy memory frame at just 26 grams, IP56 sweat/rain protection, and 8 hours of playtime on Bluetooth 5.4.
• Soynoen Bone Conduction Headphones — biggest trade-off: no volume cap, no parental app, and an adult-focused fit — plus it's explicitly not for swimming despite the water resistance.
• Giznity Kids — biggest strength: an 85 dB volume ceiling with in-app parental controls, 360° bendable memory-titanium band, rugged IP54 build, and up to 20 hours of playtime.
• Giznity Kids — biggest trade-off: a 2 KHz frequency response, higher 90 ms latency, and a lower IP54 rating that suits kids' play more than heavy adult sweat sessions.
• Pick Soynoen if the listener is you — an adult who wants situational awareness on the road and a lightweight frame that survives hard training.
• Pick Giznity Kids if the listener is a child who needs hearing protection, usage limits, and a band that bends instead of snapping.
The Soynoen pair is built around one idea: keep your ears completely open while sound travels through bone. That matters most when you're moving through traffic, a trail or a busy city street and need to hear what's happening around you. The 16.2 mm bone conduction driver pushes what the spec sheet calls immersive stereo with a soft, balanced tuning, and the 20 Hz–20,000 Hz range covers the full spectrum you'd expect for music, podcasts and calls.
Who should buy it: adults who run, cycle, hike or train outdoors and want their ears free, plus anyone who dislikes in-ear pressure after a long day. Who should skip it: parents shopping for a child — there's no volume limiter or app — and swimmers, since the IP56 rating covers sweat and rain but the manufacturer states it is not suitable for swimming.
Giznity Kids: Who It's For
The Giznity Kids headphones solve a different problem: how a child listens without turning the volume up too far. The air-conduction open-ear design keeps ears unblocked so kids stay aware of traffic and voices, and the 85 dB cap is the headline feature — a hard ceiling aimed at protecting young hearing during school, travel, entertainment and study. Dynamic-EQ tuning and a suspended speaker structure are there to keep that sound rich and balanced even at the safe volume.
The build is designed around childhood. It weighs 1.06 oz (about 30 grams), uses a 360° bendable memory-titanium band that tolerates drops, impacts and crushing, and is IP54 water-resistant. The band is compatible with glasses and helmets, and the package includes fun stickers for personalization — a small touch that helps a kid actually want to wear them.
The app layer is what separates this from a generic kids headset. Push-to-Talk Talkie sends short family voice messages screen-free with tap-to-reply, while parental controls let you view usage stats, set time limits and quiet hours, and switch on a temporary Travel Mode (up to 94 dB) for noisy places, which automatically returns to 85 dB. Bluetooth 5.4 multipoint pairs a phone and a tablet with instant switching, battery runs up to 20 hours with USB-C fast charging, and it works with iOS, Android and PC.
Who should buy it: parents who want hearing protection and oversight without hovering. Who should skip it: adult athletes who need a sweat-proof build for hard sessions — the IP54 rating and 2 KHz frequency response are tuned for kids' listening, not training.

If I were buying for myself, I'd take the Soynoen Bone Conduction Headphones. In my opinion, the combination of a 16.2 mm bone conduction driver, IP56 sweat and rain resistance, 40 ms latency and a 26-gram titanium frame is exactly what an adult runner or cyclist needs, and 8 hours covers a long training block. I'd only steer you to the Giznity Kids if the wearer is a child — in that case the 85 dB cap, parental app and 20-hour battery make it the more responsible choice, and I wouldn't hand a kid an uncapped adult headset. Two different jobs, two different picks. Check the current price on Amazon before you decide, since both sit in different budget brackets.
Yes — that's its core use case. The open design keeps your ears free to hear traffic, IP56 handles sweat and rain, and the 26-gram titanium frame is built to stay put during hard movement. Just don't swim in them.
They're capped at 85 dB by design, which is the point — clear stereo without risking young ears. If a noisy environment makes that too quiet, the app's temporary Travel Mode raises the limit to 94 dB and automatically returns to 85 dB afterward.
Yes. There's a built-in mic plus touch controls to answer, end or decline calls, and Bluetooth 5.4 multipoint lets a child switch between a phone and a tablet without re-pairing — handy for video lessons.
Purpose. The Soynoen is an adult sports headset with a bigger bone conduction driver and IP56 protection; the Giznity is a kids' headset with a volume cap, parental controls and 20-hour battery. Buy for the wearer, not the spec sheet.
