If you want an open-ear headset for a kid with IP67 protection, longer stated battery life, and two-device pairing, choose mojawa Aerra IP67; if you need a lightweight open-ear headset with a titanium wraparound frame and a USB-C charging cable, choose shokz OpenMove. For a child who wants headphones for outdoor activities, Aerra’s waterproof rating and eight-hour music-and-calls specification make it my more practical pick, while OpenMove has a clearly stated 29 g weight and a six-hour battery life.
• mojawa Aerra IP67: Its strongest case is the combination of IP67 water protection, eight hours of music and calls, and pairing with two devices. Its trade-off is that the listed product details do not give a weight or a charging-connector type.
• shokz OpenMove: Its strengths are a 29 g weight, a wraparound titanium frame, and a supplied USB-C cable. Its main trade-off is a six-hour stated battery life and sweat resistance rather than a stated IP67 waterproof rating.
• Both: Use bone conduction and an open-ear design, so they leave the ear canal unobstructed and can help the wearer remain aware of nearby sounds. Neither has a headphone jack.
• Choose Aerra if water protection, longer stated runtime, or connecting to two devices at once matters most.
• Choose OpenMove if you want a specifically stated lightweight design, physical push-button controls, and a headset described for low-impact activities.
Aerra is an open-ear, bone-conduction Bluetooth headset aimed at sports and outdoor use. Because it does not sit inside the ear, it may suit a listener who dislikes earbuds or wants to hear more of the surrounding environment while listening. That open design is useful for a walk, a bike ride, or a study session where being able to notice someone nearby matters. It does not provide noise control, so it is not the pick for shutting out a noisy room.
Its most concrete advantage is the combination of an IP67 rating and an eight-hour stated duration for music and calls. The product information describes a fully sealed, waterproof body and protection against sweat and rain. For a kid who may use headphones during outdoor activities, that rating offers a more reassuring specification than sweat resistance alone. It still makes sense to follow the manufacturer’s care guidance rather than assume any headset is indestructible.

Who should skip it: Skip Aerra if a specified low weight, push-button controls, or a clearly named USB-C cable is essential to your decision; those details are not given for this model.
OpenMove is another bone-conduction, open-ear Bluetooth headset, but its fit and activity notes are more specific. A wraparound titanium frame is described as keeping it in place for light jogs, everyday commutes, and other low-impact activities. Its stated weight is 29 g. Those details make it a straightforward option for someone who values a light headset that stays around the head rather than placing earbuds in the ears.
The battery is specified for six continuous hours of music, calls, or podcasts, and the product information gives a two-hour charge time. A USB-C charging cable is included. That makes the charging arrangement more explicit than Aerra’s listing, although Aerra has the longer stated runtime and its own quick-charge claim. OpenMove uses Bluetooth 5.1 and is described as compatible with Android, iOS, Windows, and other Bluetooth-enabled devices.
Shokz presents the sound as balanced, with bass delivered through the cheekbone, and says the headset supports calls. Its open-ear design also suits listeners who prefer not to block their ears while walking or commuting. Controls are listed as push buttons, giving the wearer a physical way to adjust settings rather than relying on touch control. The headset is described as sweat-resistant, but no IP67 rating is provided in the product details.
Who should skip it: Skip OpenMove if you need a stated IP67 waterproof rating, the longer eight-hour runtime, or simultaneous pairing with two devices.
• Best for a kid who may wear headphones outdoors in rain or heavy sweat → mojawa Aerra IP67. Its IP67 specification is the clearest water-protection advantage in this comparison.
• Best for longer stated battery life → mojawa Aerra IP67. It lists eight hours for music and calls, compared with OpenMove’s six hours.
• Best for a quick pre-activity charge → mojawa Aerra IP67. Its stated five-minute quick charge adds 1.5 hours of playtime.
• Best for a light headset with a stated weight → shokz OpenMove. Its listed weight is 29 g; Aerra’s supplied details do not state a weight.
• Best for connecting two devices at once → mojawa Aerra IP67. Its product details specifically describe simultaneous dual-device pairing.
• Best for a clearly stated charging cable and charging time → shokz OpenMove. A USB-C cable is included, and the listed charge time is two hours.
• Best for physical push-button controls → shokz OpenMove. Its controls are listed as push buttons; Aerra’s are described as touch controls.
• Best for study sessions where awareness matters → either, with a caveat. Both are open-ear, but neither lists noise control, so neither is designed to block out a distracting environment.
Buying Considerations
Separate water protection from sweat resistance. Aerra’s IP67 rating is a specific protection claim. OpenMove is described as sweat-resistant, but its information does not provide an equivalent IP rating. If rain exposure or heavy sweating is central to the decision, that distinction points toward Aerra. It does not mean every use scenario is covered, so buyers should still observe the product’s care instructions.
Match the battery to the routine. Aerra lists eight hours and a short quick-charge option; OpenMove lists six hours and a two-hour charge time. A child who uses headphones for long stretches may appreciate Aerra’s larger stated runtime. For shorter commutes or workouts, OpenMove’s stated battery may be sufficient. Actual listening habits and charging routines matter more than a headline figure alone.
Consider how the headset will be controlled. Aerra lists touch controls, while OpenMove uses push buttons. A child may have a preference, and gloves or wet hands could make control style relevant. The information provided does not establish which is easier for every user, so it is worth considering the wearer’s comfort with each approach.
Keep expectations realistic for calls and gifts. Aerra specifies dual microphones and call-focused features; OpenMove also describes call support. Neither product’s supplied details provide a microphone performance measurement, so those claims do not guarantee a particular result in a noisy place. Either might be considered as a wireless headset valentines day gift for someone who wants open-ear listening, but the recipient’s fit preference and need for water protection should guide the choice.
I would choose the mojawa Aerra IP67 for a kid because its stated IP67 protection, eight-hour battery life, and dual-device connection cover more of the practical outdoor-use needs I would prioritize. The quick-charge feature is another useful detail for a busy routine. I would choose OpenMove instead if the 29 g listed weight, push-button controls, or included USB-C cable matters more than waterproofing and longer runtime.
For a child who may use headphones outdoors, I’d lean toward Aerra because it lists IP67 protection and an eight-hour battery life. OpenMove has a stated 29 g weight and a wraparound titanium frame, which may appeal to someone who prioritizes a lightweight, secure fit.
Both are described as supporting calls. Aerra lists dual microphones, while OpenMove’s product details describe call use and clear conversations. The supplied information does not give a measured microphone-quality result, so performance in noisy surroundings should not be assumed.
Aerra has an IP67 rating and is described as waterproof and sweatproof. OpenMove is described as sweat-resistant, but the provided details do not specify an IP67 rating.
They are wireless Bluetooth headphones, but they are not earbuds that sit inside the ear. Both use bone conduction with an open-ear design and are described as supporting calls; that design keeps the ear canal unobstructed rather than isolating the listener from surrounding sound.
