mojawa Aerra IP67 vs shokz OpenMove at a Glance
• mojawa Aerra IP67 — biggest strength: IP67 sealing on a fully integrated, one-piece body, paired with 8 hours of music and calls and a 5-minute quick charge that adds roughly 1.5 hours of playtime. Nothing in this matchup handles heavy sweat and rain as openly.
• mojawa Aerra IP67 — biggest trade-off: touch controls and a listed item weight of 0.29 kg, which reads more like a packed shipping weight than a bare headset figure — and touch gestures are fussier for small hands than buttons.
• shokz OpenMove — biggest strength: 29 g on a wraparound titanium frame with honest push-button volume controls. It disappears on your head and you can operate it without looking.
• shokz OpenMove — biggest trade-off: the spec sheet calls it sweat-resistant rather than giving it a formal IP rating, and battery life is 6 hours with a 2-hour charge time.
• Buy the mojawa Aerra IP67 for a kid who runs hot, plays outside in any weather, and needs one charge to cover a long day.
• Buy the shokz OpenMove for a kid doing light jogs, school commutes and everyday listening who wants the lightest possible thing on their head and controls they can't fumble.
The Aerra's whole pitch is durability plus endurance, and the specs back that up rather than just hinting at it. IP67 on an integrated, fully sealed body means heavy sweating during exercise and getting caught in the rain are non-issues, which is exactly the failure mode that kills cheap headsets worn by kids. Eight hours of music and calls is the longest figure in this comparison, and the magnetic fast charging is genuinely useful: five minutes on the cable gets you about 1.5 hours of playback. That's the difference between a headset that goes back in the bag dead and one that's ready for the ride home.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
The rest of the package is built for multitasking. Bluetooth 5.2 with dual device connection means it can be paired to two things at once — a kid's tablet and a parent's phone, say — without repairing every time. There are dual silicone microphones with ENC noise cancellation for calls, which is worth noting because open-ear designs leak background sound into the mic path. And the sound is tunable: three modes (Equalizer, Bass Boost, Vocal Enhancement) with mojawa saying the tuning was calibrated with input from music producers, plus an Audio-Haptics system that emphasizes low-frequency rhythm. The physical design is plastic and silicone in green and purple, with a two-year warranty.
Buy it if: your kid sweats hard, plays outdoors year-round, needs a single charge to last a school day plus practice, or shares devices. Skip it if: you want the absolute lightest option, you'd rather have physical buttons than touch controls, or you want a carrying case in the box — the Aerra's listed contents are the headphones, a cable and the manual only. And if active noise cancellation is on your list, skip both headsets here; the Aerra lists no noise control at all, and that's intentional for an open-ear design.
The OpenMove wins on physics. At 29 g with a wraparound titanium frame, it's the kind of headset you forget you're wearing, and the earbud-free open-ear shape is specifically designed to avoid ear fatigue over long listening sessions. That hook-style frame stays put through light jogs and everyday commutes — Shokz positions it for low-impact activity rather than hard training, and the sweat-resistant build is described in exactly those terms, without a formal IP number attached. That's the honest trade-off versus the Aerra.
Everything else about the OpenMove is about simplicity and predictability. Push-button volume controls are easier to find and press than a touch surface, especially with cold hands or on a kid who's still learning the device. Pairing is universal across Android, iOS, Windows and other Bluetooth devices, with a stated range of around 33 feet. The audio spec is a bone conduction driver with 8-ohm impedance, 96 dB sensitivity and a 20Hz–20KHz frequency range, and Shokz describes the tuning as balanced with rich bass delivered through the cheekbone, plus clear call quality. Six hours of playback with a 2-hour charge via the included USB-C cable is a straightforward, no-surprises setup.
Buy it if: you want the lightest fit, button controls, a carrying case included in the box, and a headset that handles commutes, walks and light exercise. The package also includes five pairs of stickers for personalization, which kids tend to enjoy more than adults do. Skip it if: your kid is a heavy sweater or trains outdoors in the rain, you need more than six hours away from a charger, or you want two devices connected simultaneously — the OpenMove's sheet lists Bluetooth 5.1 without a multipoint claim.
Side-by-Side: Which Should You Choose?
• Best for battery life → mojawa Aerra IP67. Eight hours versus six, plus a 5-minute top-up worth about 1.5 hours.
• Best for fast charging → mojawa Aerra IP67. A 5-minute partial charge beats waiting out a 2-hour full charge on the OpenMove.
• Best for the lightest possible fit → shokz OpenMove. 29 g with a titanium wraparound frame is a different weight class.
• Easiest to operate, especially for a kid → shokz OpenMove. Physical push buttons beat touch gestures when you can't look down.
• Best for two devices at once → mojawa Aerra IP67. Dual device connection is listed; the OpenMove doesn't claim it.
• Best for tuning the sound to your taste → mojawa Aerra IP67. Three selectable modes versus one balanced tuning.
• Comfortable bluetooth headset for hiking → both, with a split. Take the Aerra for wet weather and long days, the OpenMove for hot, dry trails where 29 g matters more. And if you're actually shopping for noise canceling ear clip headphones or sleep headphones bluetooth 5.4, neither of these is it — neither lists noise control, and these run Bluetooth 5.2 and 5.1 respectively.
In my opinion, the mojawa Aerra IP67 is the better buy for a kid, and it's not particularly close. IP67 sealing, eight hours of playback, a five-minute emergency charge and dual device pairing are the four things that actually break a kid's headset routine — weather, forgetting to charge, and constantly repairing. The Aerra answers all four. I'd only switch to the shokz OpenMove if weight and button simplicity are your top priorities, or if the activity is genuinely light and dry. It's a well-built, featherweight headset; it's just the less forgiving one.
FAQ
For most kids, the Aerra IP67 — the sealed IP67 body and 8-hour battery hold up to sweat, rain and long days better. Choose the OpenMove if your kid is gentle on gear and you want the lightest fit with push-button controls.
No. Neither lists noise control, and that's by design: open-ear bone conduction keeps your ears uncovered so you stay aware of traffic and surroundings. If you specifically want noise canceling ear clip headphones, these are the wrong category.
The Aerra lists 8 hours of music and calls with magnetic fast charging — 5 minutes adds about 1.5 hours. The OpenMove lists 6 hours with a 2-hour charge via USB-C.
The OpenMove is lighter at 29 g, so it's the more forgettable option on hot, dry trails. The Aerra is the better pick for wet weather, heavy sweat or days when you don't want to think about charging — neither design inserts into the ear, so both avoid ear-canal pressure.
