If you want a more weather-sealed design with longer stated battery life for a kid, choose mojawa Aerra IP67; if you need a straightforward open-ear headset with a wraparound titanium frame, choose Shokz OpenMove. Both use bone conduction, so neither sits inside the ear, and both keep the listener more connected to nearby sounds than sealed earbuds do.
• mojawa Aerra IP67: Its standout strengths are an IP67 waterproof and sweatproof body, up to eight hours for music and calls, and the option to connect two devices. Its trade-off is that its open-ear design does not isolate the listener from surrounding sound.
• Shokz OpenMove: It offers a secure wraparound titanium frame, open-ear listening, and six hours of stated battery life. Its trade-off is a shorter stated runtime and sweat resistance rather than a stated IP67 waterproof rating.
• Choose mojawa Aerra IP67 if water protection, longer listening time, or switching between two paired devices matters most.
• Choose Shokz OpenMove if you prefer its titanium-frame design and want a simple open-ear headset for workouts and everyday listening.
• For a kid, I’d give particular weight to fit, listening habits, and the need to stay aware of the environment—not just the battery figures.
The Aerra IP67 is an open-ear bone-conduction headset with a built-in microphone and Bluetooth 5.2. Because it doesn’t sit inside the ear, it may suit someone who dislikes inserted earbuds or wants to hear more of what is happening nearby while listening. The open design is useful for outdoor activity, though it does not block ambient noise.
Its clearest practical advantage is the stated IP67 waterproof and sweatproof construction. That makes it the more compelling pick on paper for workouts in heavy sweat or getting caught in rain. The listed battery life is up to eight hours for music and calls, and a five-minute quick charge is stated to add 1.5 hours of playtime. It can also connect to two devices simultaneously, which may help someone moving between a phone and another Bluetooth device.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
The Aerra is a sensible choice for a buyer who values water protection, longer stated runtime, and open-ear comfort. It may also suit a kid who needs an adult-sized open-ear headset, but the product information describes its age range as adult, so I wouldn’t treat it as a child-specific fit. Skip it if you need noise isolation, or if you specifically want an in-ear design. Its listed controls are touch-based, and it has no headphone jack.
The OpenMove is also an open-ear bone-conduction headset, with a wraparound titanium frame intended to stay in place during lower-impact activities and everyday commuting. It is described as sweat-resistant, and its open-ear layout lets the listener remain more aware of surrounding sounds. That can be useful for a walk, a light jog, or listening while doing chores, but it is not a substitute for noise-canceling headphones.
Its stated battery life is six hours for music and calls. The listed charging time is two hours, and the package information includes a USB-C charging cable and a protective case. Bluetooth 5.1 supports wireless pairing with compatible devices. The product information gives a weight of 29 grams, while the frame design is the detail that most distinguishes it from the Aerra.
Consider the OpenMove if the titanium-frame fit appeals to you and you want a simple headset for everyday movement. It can be used for calls, but neither model’s open-ear design will keep conversation private or shut out nearby noise. Skip it if IP67 protection or the longer stated battery life is your main priority. For a kid, remember that the stated age range is adult; a secure-looking frame does not by itself establish a child-sized fit.
• Best for stated battery life → mojawa Aerra IP67. It lists up to eight hours for music and calls, compared with six hours for the OpenMove.
• Best for water protection → mojawa Aerra IP67. Its data specifies IP67 waterproof and sweatproof protection; OpenMove is described as sweat-resistant.
• Best for a quick top-up → mojawa Aerra IP67. A five-minute charge is stated to provide an additional 1.5 hours of playtime. OpenMove lists a two-hour charge time, without a comparable quick-charge figure in its product information.
• Best for connecting two devices at once → mojawa Aerra IP67. It specifically supports simultaneous pairing with two devices.
• Best for a titanium-frame fit → Shokz OpenMove. Its wraparound titanium frame is the clear design distinction.
• Best for staying aware while listening → either. Both use open-ear bone conduction, so neither seals the ear. Nearby sound can still reach the listener, though audio may also be harder to hear in noisy settings.
• Best for calls and studying → either, with realistic expectations. Both are described as supporting calls, and Aerra lists microphones. For a with mic headset for studying, remember that open-ear listening offers no stated noise isolation.
• Best for a weather-conscious workout → mojawa Aerra IP67. Its stated IP67 protection is the stronger documented choice for rain and heavy sweat.
I’d choose the mojawa Aerra IP67 for a kid if the priority is an open-ear design paired with IP67 protection and longer stated battery life. Those features give it the edge for active use and longer stretches away from a charger. I’d still check that the adult-described fit works comfortably and securely for the child. For someone who prefers a wraparound titanium frame and only needs six hours of listed runtime, I’d choose the Shokz OpenMove instead.
Both are described as supporting calls. Aerra lists dual silicone microphones, while OpenMove is described as providing clear conversations. Neither product’s open-ear design is stated to block surrounding noise, so a noisy place may still make calls harder to follow.
The Aerra has a stated IP67 waterproof and sweatproof rating. OpenMove is described as sweat-resistant, but its product information does not give an IP67 rating. If rain or heavy sweat is a deciding factor, Aerra has the clearer documented advantage.
Either could suit someone who wants an open-ear Bluetooth headset for calls, music, or workouts. The better fit depends on the recipient: Aerra emphasizes water protection and longer stated battery life, while OpenMove has a wraparound titanium frame.

They can suit a listener who wants audio without inserting earbuds, but neither model lists noise isolation.
