They look like rivals because both sit outside your ear canal. They are not really rivals. One is built around movement, the other around your voice.
• IHAO Air Conduction — biggest strength: open-ear arms that rest on your cheekbones, around 46 g of weight, and an IPX5 rating that shrugs off sweat and rain. Built for sport.
• IHAO Air Conduction — biggest trade-off: no boom mic, no noise control, and no battery figure published in the spec sheet. Fine for music and calls through the built-in mic, less ideal if your voice is the whole point.
• DIYSTAR Alpha Ears Headset — biggest strength: an extended ENC boom mic plus a flexible neckband, with up to 6 hours per charge and roughly 33 ft of Bluetooth range. Built for talking.
• DIYSTAR Alpha Ears Headset — biggest trade-off: IPX4 only, and a neckband shape that suits desk, car and warehouse work better than sprint intervals.
• Who each pick is for: IHAO if your priority is comfort while you move; DIYSTAR if your priority is being heard clearly while you work.
The IHAO Air Conduction is an open-ear Bluetooth headphone that sits on your cheekbones rather than inside your ears. That single design decision drives everything else. Your ear canal stays completely open, so you keep hearing traffic, footsteps, gym chatter and the world around you while music plays. The spec sheet describes the fit as pain-free even over long sessions, and at roughly 46 g it is light enough that you are not constantly adjusting it.
The sport side is where it makes the most sense. IPX5 means sweat and rain are not a problem, and the arms are shaped to hold steady through running, cycling and gym work. Bluetooth 5.2 handles the connection, and the driver covers a 20 Hz – 20,000 Hz range, which is the full span most people can actually hear. There is a built-in mic for calls, and it is a wireless-only design with no headphone jack.
Who should buy it: runners, cyclists, gym-goers and anyone who wants music without sealing off their ears. Who should skip it: if you spend your day on calls, in a car, or on a dispatch channel, there is no boom mic here and no noise control listed, so your voice will not get the same treatment. Same if you need a published battery number before you commit — the sheet does not give one. And if you want the option of a wired fallback, this is not it.
The DIYSTAR Alpha Ears Headset takes the same open-ear idea and points it at work instead of workouts. The headline feature is the extended boom mic with ENC noise-reduction, which is there to pull your voice forward and push background noise back during calls, online meetings and dispatch communication. If you have ever taken a call on a mic buried in your earpiece, you know why that matters.
The rest of the design follows the same logic. A flexible neckband holds the open-ear arms in place, and the spec sheet notes it plays nicely with glasses and hats — a real consideration if you wear either all day. Bluetooth 5.2 pairs quickly and holds a connection out to roughly 33 ft, so you can leave the phone on a desk or seat and keep talking. Battery life is up to 6 hours per charge, and IPX4 covers light rain and sweat, which is enough for commuting, outdoor work and casual workouts. It comes as a single pack.
Who should buy it: drivers, dispatchers, delivery and warehouse workers, and anyone on long hands-free calls who needs their voice to land clearly. Who should skip it: if you want one pair for hard training in heavy rain, IPX4 and a neckband are the wrong tools — the IHAO is the better shape and the tougher rating. Also skip it if you dislike anything around your neck while you move.
• Best for running, cycling and gym work → IHAO Air Conduction. IPX5, around 46 g, and arms designed to stay put through intense activity.
• Best for calls and hands-free work → DIYSTAR Alpha Ears Headset. The ENC boom mic is the whole reason this product exists.
• Best for wet-weather and heavy-sweat use → IHAO Air Conduction. IPX5 beats IPX4 on paper, and there is no neckband to shift around.
• Best for all-day wear with glasses or a hat → DIYSTAR Alpha Ears Headset. The flexible neckband and open-ear arms are specifically described as working with both.
• Best for knowing your battery budget in advance → DIYSTAR Alpha Ears Headset. Up to 6 hours is stated; the IHAO sheet does not publish a runtime.
• Best for sitting away from your phone → DIYSTAR Alpha Ears Headset. Roughly 33 ft of Bluetooth range is spelled out.
• Best for a simple music-and-podcast companion → IHAO Air Conduction. Bluetooth 5.2, a full-range driver and a built-in mic cover the basics without extra hardware.
• Best if you want the most minimal thing on your head → IHAO Air Conduction. No boom arm, no neckband, just arms on your cheekbones.
In my opinion, the DIYSTAR Alpha Ears Headset is the more useful buy for most people, because the boom mic solves a problem the IHAO cannot — being understood on a call while your hands are busy. That is the harder job, and it is the one people actually notice failing. That said, if your version of "using headphones" means lacing up and running in the rain, I would take the IHAO Air Conduction without hesitating: IPX5 and a 46 g open-ear frame are simply the right specs for that life. Pick the job first, then the headset.
FAQ
For your own voice, the DIYSTAR Alpha Ears Headset — it has an extended ENC boom mic positioned near your mouth. The IHAO has a built-in mic for calls but no boom arm and no noise control listed, so it is the weaker option for anything beyond a quick conversation.
You can — it is wireless, open-ear and IPX4 water-resistant. But the flexible neckband and lighter water protection make it a better fit for commuting, driving and outdoor work than for hard training. For serious sweat and rain, the IHAO's IPX5 and sport-focused frame are the better match.
No. Both are open-ear designs that leave your ear canal uncovered, which is the point — you stay aware of traffic, colleagues and surroundings. The DIYSTAR adds ENC on the microphone side, which cleans up what other people hear, not what you hear.
The DIYSTAR Alpha Ears Headset is rated at up to 6 hours of wireless use per charge. The IHAO Air Conduction spec sheet does not list a battery figure, so treat runtime as unconfirmed and check the current listing details before you decide.
