If you want a sealed IP67 open-ear headphone with dual-device pairing, touch controls and three selectable sound modes — which is exactly the setup I'd suggest for kid use, where hearing traffic and a parent matters far more than booming bass — choose mojawa Aerra IP67; if you need the featherweight 26 g wraparound frame and 8th-generation bone conduction that Shokz has spent years refining, choose shokz OpenRun Aeropex. Everything below explains how I got to that split.
• mojawa Aerra IP67, biggest strength: a genuinely sealed, integrated IP67 body combined with dual-device Bluetooth 5.2 and three selectable audio modes — a lot of flexibility in one open-ear package.
• mojawa Aerra IP67, biggest trade-off: touch controls instead of physical buttons, and no noise-control feature listed at all — its "ENC" is about your microphone during calls, not about blocking the world around you.
• shokz OpenRun Aeropex, biggest strength: a 26 g nickel-titanium wraparound frame that barely registers on your head, backed by Shokz's 8th-generation bone conduction driver and a magnetic charging system with a moisture alert.
• shokz OpenRun Aeropex, biggest trade-off: the spec sheet lists Bluetooth 5.1 and no dual-device pairing, so anyone juggling a phone and a tablet is working with one connection at a time.
• Who each pick is for: mojawa Aerra IP67 for the multi-device household, the rainy-weather hiker and the kid who needs to hear what's happening around them; shokz OpenRun Aeropex for the runner or cyclist who wants the lightest, most stable band and doesn't care about pairing two things at once.
The Aerra's headline feature is its body. The IP67 rating isn't a coating or a splash guard — it's an integrated, fully sealed shell, which is the difference between "fine in light rain" and "fine when you get caught in a downpour an hour from the trailhead." That matters for hiking and cycling, and it matters even more if a kid is wearing them, because kids are hard on gear and rarely remember to take anything off before jumping in a puddle.
The second thing that stands out to me is the dual-device connection over Bluetooth 5.2. You can pair a phone and a tablet at the same time and move between them without repairing. In a house where a kid uses a tablet for school and a parent's phone for calls, that's a genuinely useful everyday detail rather than a spec-sheet bullet. mojawa also talks up lower latency and stable pairing, which lines up with what you'd want for video on a tablet.

Buy it if: you want one open-ear pair that moves between two devices, survives heavy sweat and rain, and gives you a reason to fiddle with sound modes. It's also the one I'd hand to a kid, because the open-ear design keeps them connected to the environment and the sealed body survives the way kids actually use things.
Skip it if: you want physical buttons you can find by feel with cold, wet hands (the Aerra uses touch control), you expect actual noise canceling, or you want a neutral, unprocessed sound — this is an effects-driven presentation, not a studio monitor.
Shokz built its reputation on the fit, and the OpenRun shows why. The frame is nickel-titanium alloy wrapped in plastic and silicone, and the whole thing weighs 26 g. That's a wraparound band that sits behind your head and hooks over your ears without ever entering them — no pressure, no break-in period, nothing to adjust mid-run. When someone searches for a comfortable Bluetooth headset for hiking, this is the design language they're picturing.
The audio comes from Shokz's 8th-generation bone conduction driver, with a listed frequency range of 20 Hz to 20,000 Hz, 105 dB sensitivity and 8.5 ohm impedance. The pitch is awareness: sound travels through your cheekbone to your inner ear while your ear canal stays open to traffic, trail chatter and whoever is shouting your name. It's IP67 rated for sweat and water, with a moisture detection alert that warns you if the charging contacts are wet — a small feature I appreciate, because it prevents the most common way waterproof electronics get ruined. Note the manufacturer is explicit that it isn't suitable for swimming.
Battery is 8 hours of music and calls, matching the Aerra, and the 10-minute quick charge adds up to 1.5 hours of playback. You get a magnetic charging cable, a protective carrying case and a Shokz sport headband in the box, along with a two-year warranty. Controls are physical buttons for volume, which a lot of people prefer on a run.
Buy it if: you prioritize the lightest possible fit, you want buttons instead of a touch surface, or you want a case included and a brand whose whole product line is bone conduction.
One sizing note that matters for families: this is the standard-size band, and Shokz says a shorter-band Mini version exists for smaller heads. If you're buying for kid use, that's worth checking before you commit.
• Best for switching between two devices → mojawa Aerra IP67. Dual-device Bluetooth 5.2 versus Bluetooth 5.1 with no multipoint listed.
• Best for the lightest, most stable fit → shokz OpenRun Aeropex. 26 g of nickel-titanium wraparound frame is hard to argue with on a long run.
• Best for battery life → a tie on runtime. Both are rated at 8 hours. The Aerra's edge is topping up: 5 minutes gets you 1.5 hours, versus 10 minutes for the same 1.5 hours on the OpenRun.
• Best for calls → mojawa Aerra IP67 on paper. Dual silicone microphones with ENC noise cancellation for your voice, where the OpenRun simply lists a built-in mic.
• Best for tuning your sound → mojawa Aerra IP67. Three modes (Equalizer, Bass Boost, Vocal Enhancement) against none listed for the OpenRun.
• Best if you want real buttons → shokz OpenRun Aeropex. Volume buttons beat a touch surface when your hands are cold, wet or gloved.
• Best for rough weather and rough handling → mojawa Aerra IP67. Both are IP67, but the Aerra's fully sealed integrated body is described as built for exactly that abuse, and Shokz itself steers you away from swimming.
In my opinion, the mojawa Aerra IP67 is the one I'd buy for most households, and especially if a kid will be wearing it. Dual-device pairing solves a daily annoyance, the 5-minute top-up fits real life better, three sound modes give you something to adjust, and a sealed IP67 body is the right answer for sweat, rain and being dropped in a bag. For kid use in particular, open-ear awareness plus that sealed shell is a combination that makes sense.
The shokz OpenRun Aeropex is not the lesser product — it's the more specialized one. If you want the lightest wraparound frame, real buttons and a case in the box, and you only ever connect one device, it's the better pick. Just confirm the band size first if a smaller head is involved.
Neither is better in the abstract. Shokz wins on weight and frame stability for pure running. mojawa wins if you want dual-device pairing, three sound modes and a fully sealed body. For most runners I'd lean Shokz on fit alone; for mixed use I'd lean mojawa.
No. Both are open-ear bone conduction designs that deliberately leave your ear canal open. mojawa's ENC is about cleaning up your voice for callers. Shokz lists sound isolation as its noise-control approach, but with nothing sealed in your ear, you'll still hear the world. If you're shopping for noise canceling ear clip headphones, this category isn't it — and that's the point of the design.
The mojawa Aerra IP67 gets my vote, mainly for the sealed IP67 shell and dual-device pairing. The caveat is sizing: neither sheet gives a band length for the Aerra, and the OpenRun is the standard-size band, so check the Shokz Mini if the head is small.
No. mojawa runs Bluetooth 5.2 and Shokz 5.1, and neither is marketed as sleep wear — the rigid wraparound band isn't built for lying on a pillow. For value, check the current price on Amazon for both before deciding, since that's the one number that changes daily.
