If you want long battery life sports headphones with dual-device pairing and a quick top-up, choose mojawa Aerra IP67; if you need a wraparound fit with an included headband, choose shokz OpenRun Aeropex. For a kid, I’d lean toward the simpler fit and everyday flexibility that match their routine, while remembering both models are described for adults.
Both use an open-ear bone-conduction design, so they leave the ears uncovered rather than sitting inside them. The deciding differences are dual-device connectivity and charging details on the mojawa, versus the Shokz’s included sport headband and moisture-detection alert.
• mojawa Aerra IP67: IP67 protection, up to eight hours of music and calls, two-device pairing, and a five-minute quick charge for up to 1.5 hours of playtime. Trade-off: the supplied details don’t identify an included headband or a charging moisture alert.
• shokz OpenRun Aeropex: Open-ear bone-conduction listening, an included sport headband, IP67 water resistance, and a moisture-detection alert before charging. Trade-off: Bluetooth 5.1 and no stated dual-device pairing.
• Both leave the ears open, offer up to eight hours of use, and are described for adult wearers.
• Choose mojawa for dual-device pairing and the shorter quick-charge window; choose Shokz if the headband and charging alert matter more.
Aerra makes sense for someone who wants open-ear listening without earbuds inserted into the ear canal. Its bone-conduction drivers and open-ear fit leave the wearer able to hear the surrounding environment, which can be useful during a run or outdoor workout. The design is described as comfortable and secure without pressure from insertion, though comfort is personal and fit can vary.

The IP67 rating and sealed design suit sweaty workouts and exposure to rain. Audio features include three modes—Equalizer, Bass Boost, and Vocal Enhancement—and a system intended to reinforce low-frequency rhythms. I’d shortlist Aerra for workouts, calls, and switching between two devices. I’d skip it if you specifically want the included Shokz headband or the Shokz moisture-detection charging alert; those features aren’t listed for Aerra.
OpenRun Aeropex is a straightforward choice for someone who wants an open-ear sports headset with a wraparound frame. It uses bone-conduction technology, keeps the ears uncovered, and includes a Shokz sport headband. The supplied description also says the model is available in two sizes, which may help some people find a more secure fit. Both products are described for adults, so neither should be assumed to be a child-sized headset.
For workouts in wet conditions, the stated IP67 water resistance is paired with a moisture-detection alert intended to help make charging safer. The product information says it is not suitable for swimming. Battery life is listed at up to eight hours, with a ten-minute quick charge providing up to 1.5 hours of use. That is a useful fallback, though it takes longer than Aerra’s listed five-minute quick-charge window for the same stated playtime.
OpenRun uses Bluetooth 5.1 and offers button controls for volume. The supplied details don’t specify dual-device pairing, so I wouldn’t choose it on the assumption that it can stay connected to two devices simultaneously. It fits shoppers who value the included headband, a charging moisture alert, and physical controls. If managing two paired devices is central to your routine, Aerra has the clearer feature advantage.
• Best for pairing with two devices → mojawa Aerra IP67. It explicitly supports simultaneous connection to two devices; that feature is not listed for OpenRun.
• Best for a faster quick-charge top-up → mojawa Aerra IP67. Its stated five-minute charge provides up to 1.5 hours of playtime, while Shokz lists ten minutes for up to the same amount.
• Best for an included workout headband → shokz OpenRun Aeropex. A Shokz sport headband is included with the described package.
• Best for a charging moisture alert → shokz OpenRun Aeropex. Its listed alert is designed to flag moisture before charging.
• Best for sweat and rain protection → a tie on the stated rating. Both are described with IP67 protection. Shokz explicitly notes that OpenRun is not intended for swimming; don’t treat an IP rating as a reason to swim with either model.
• Best for long sessions away from a charger → a tie on listed battery life. Both specify up to eight hours of music and calls.
• Best for choosing a sound mode → mojawa Aerra IP67. It lists Equalizer, Bass Boost, and Vocal Enhancement modes.
• Best for yoga or general fitness where awareness matters → either, with a fit-based decision. Both use an open-ear design. For sports earbuds for yoga, consider whether you prefer Aerra’s listed dual-device pairing or the included Shokz headband.
I’d choose the mojawa Aerra IP67 for its dual-device pairing and five-minute quick-charge feature, which make it the more flexible option for my day-to-day use. For a kid, I’d still check the fit carefully: both products are described for adults, so neither is presented as specifically child-sized. If the included headband and charging moisture alert are the priorities, I’d choose OpenRun Aeropex instead.
