• sixco Open Ear — biggest strength: an open, non-in-ear build with skin-friendly silicone and a memory-metal ear hook, plus a tuning deliberately biased toward a balanced, slightly warm low-end for long, comfortable sessions.
• sixco Open Ear — biggest trade-off: it leans on a high-fidelity, open-directional approach that rewards good source files, and it's the heavier of the two at 60 g.
• IHAO Air Conduction — biggest strength: a lightweight open-ear frame (around 46 g) with Bluetooth 5.2 and a claimed IPX5 sweat/rain rating — an obvious sport-first design.
• IHAO Air Conduction — biggest trade-off: no listed noise control and no charging case in the spec sheet, and its driver is listed as a bone-conduction type despite the "air conduction" name.
• Who each pick is for: the sixco suits commuters, long-shift workers, and older or sensitive-eared listeners who want all-day comfort; the IHAO suits runners, cyclists, and gym-goers who want the lightest possible setup.
The sixco Open Ear is built around one idea: you should be able to forget you're wearing it. The outer surface is liquid skin-friendly silicone, and the ear hook hides a flexible memory-metal core so it bends to your ear and stays put. Because it's an open-back, non-in-ear design, nothing plugs your canal — you keep your surroundings in your ears while your music plays alongside them. If you've ever pulled a bud out after two hours and felt that dull ache, that's the exact problem this shape is trying to avoid.
Then there's the tuning. sixco describes the overall sound as balanced with a slight lift in the mid- and low-frequency range — enough body to keep things engaging, but not so much that it turns into a bass cannon. The stated goal is that the music doesn't get boring after a long listen and your ears don't get tired. That's a meaningful design choice: it's aimed at people with sensitive ears or anyone who wears headphones for hours at a stretch. It's also tuned for high-fidelity, open-directional playback — the pitch is closer-to-natural listening, clear vocals, and percussion that sits naturally rather than slamming. sixco even notes that the better your source file, the more you'll get out of it, which is a fair warning that lossy streams may not show it off.
IHAO Air Conduction: Who It's For
The IHAO Air Conduction is the sport-first option, and the spec sheet reads like it. It rests on your cheekbones and leaves your ears fully open — IHAO's own framing is a pain-free experience even over long use, and the open placement is the reason. At around 46 g it's noticeably lighter than the sixco, and the design brief is clearly "stay put during intense activity": running, cycling, gym work. If your priority is not feeling the headphones at all while you move, this is the lighter frame to look at.
Bluetooth 5.2 is the connectivity story here, described as stable and fast for uninterrupted playback and clear calls. That's the current-generation spec most buyers expect, and for a sport set it matters — you don't want a dropout mid-sprint. The other headline is the claimed IPX5 rating: sweatproof and rainproof, which covers the realistic abuse of a workout or a drizzly run. The frequency range is listed at 20 Hz – 20,000 Hz, the standard full-range window.
Two things a careful buyer should weigh. First, the audio driver type is listed as a bone-conduction driver, even though the product name and marketing say "air conduction" — worth knowing, because bone conduction and air conduction don't feel or sound identical. Second, noise control is listed as None, so there's no active noise handling on the spec sheet at all. And while the description mentions multiple colors, the sheet only confirms F806 Black, so I wouldn't assume a color choice without checking.
Who should buy it: runners, cyclists, and gym-goers who want a light, secure, sweat-tolerant open-ear set with modern Bluetooth. Who should skip it: if you want a charging case, a battery-status display, or any noise-control feature, this one doesn't list them.
Side-by-Side: Which Should You Choose?
• Best for running, cycling, and gym work → IHAO Air Conduction. Around 46 g, a secure sport fit, and a claimed IPX5 sweat/rain rating.
• Lightest to wear → IHAO Air Conduction. Roughly 46 g versus 60 g for the sixco.
• Best for calls and modern connectivity → IHAO Air Conduction. Bluetooth 5.2 is the newer, more current spec of the two.
• Best for safer outdoor awareness → either, with a caveat. Both are open designs that keep your ears free, but the sixco leans into the "stay connected to your surroundings" pitch for driving and outdoor work.
• Best for long listening sessions without ear fatigue → sixco Open Ear. The balanced, slightly warm tuning and open fit are purpose-built for hours of use.
• Best for audio quality from good source files → sixco Open Ear. Its high-fidelity, open-directional tuning is the one that explicitly rewards lossless music.
• Best for battery convenience → sixco Open Ear. It lists a charging case with an LED digital display, which the IHAO spec sheet doesn't mention.
In my opinion, the sixco Open Ear is the better buy for most people. It's the more complete package: a comfort-first open design, a tuning made for long sessions rather than short bursts, a charging case with a visible battery display, and a 1.5-year warranty description. The IHAO is the smarter pick only if sport is your whole use case — it's lighter and carries the IPX5 rating and Bluetooth 5.2 you want when you're moving. So: for daily wear, commuting, and hours of listening, I'd take the sixco. For a dedicated workout pair, the IHAO makes more sense. If budget is your deciding factor, check the current price on Amazon for both before you commit, since that's the one number that can flip this decision.
FAQ
IHAO Air Conduction. Its whole design brief is intense activity — lighter frame, secure sport fit, and a sweatproof/rainproof IPX5 claim. The sixco is sweat resistant too, but at 60 g it's the heavier option for a hard workout.
No. The spec sheet lists noise control as None. The sixco, by contrast, lists adaptive noise cancellation, though on an open-ear design that's mainly about call clarity rather than blocking out your surroundings.
sixco Open Ear, based on the spec sheets. It lists a charging case with an LED digital display and a charge time of about 1.5 hours. The IHAO sheet doesn't mention a case or a battery indicator, so I can't claim one. For exact battery figures on either, verify the current listing details before buying.
