How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a single lightweight headband that stays put on long rides and leaves your ears totally open, choose IHAO Air Conduction; if you need a clip-on pair with a charging case, far more playtime and a newer Bluetooth version, choose MZYMI Open Ear Earbuds.
• IHAO Air Conduction — biggest strength: one-piece open-ear headband design, roughly 46 g, IPX5, that rests on your cheekbones and doesn't fall off during sport.
• IHAO Air Conduction — biggest trade-off: no charging case and no stated playtime figure, so battery life is a genuine unknown going in.
• MZYMI Open Ear Earbuds — biggest strength: Bluetooth 5.4, a 10-hour single-charge figure, up to 56 hours with the case, and a 10-minute quick charge for 2 hours.
• MZYMI Open Ear Earbuds — biggest trade-off: they're tiny clip-ons at 5.2 g each, which means more parts to keep track of and a fit that depends on your ear shape.
• Cycling pick: IHAO Air Conduction if you want the simplest, most secure option to grab and go.
• All-day and multi-ride pick: MZYMI Open Ear Earbuds if you'd rather carry a case and never think about charging mid-week.
The IHAO Air Conduction is built around one idea: a single, lightweight open-ear band that sits on your cheekbones and leaves your ear canals completely open. There's nothing to push into your ear and nothing to fall out. For cycling specifically, that's a meaningful design choice. The band hooks over your ears as one continuous piece, so there are no separate buds to fumble with at a red light or lose on a rough stretch of road.
The spec sheet backs up the sport angle. IHAO lists roughly 46 g for the headband, Bluetooth 5.2, and an IPX5 rating that covers sweat and rain. The driver is listed as a bone conduction type, which is worth flagging because it tells you the sound is delivered through contact rather than through the air into your ear — a different listening feel than a conventional earbud. IHAO also states it can connect to two devices at once, which is handy if you want your phone and a bike computer or laptop paired at the same time.
Who should skip it? Anyone who needs a guaranteed multi-hour figure or a charging case. IHAO doesn't publish a playtime number on this sheet, and there's no case in the package description. It's also worth knowing the sheet lists noise control as "None" — there's no active noise cancellation here. And if you specifically want in-ear isolation, this is the wrong category of product entirely.
MZYMI Open Ear Earbuds: Who It's For
MZYMI takes the opposite approach: two small clip-on units — the brand calls the design OpenEarRing — that hook onto the outside of your ear rather than sitting in it. Each one is listed at just 5.2 g, and the flexible C-bridge is described as adapting to different ear shapes. The enclosure material is silicone, which matters for comfort on longer rides and for grip once you start sweating.
Where MZYMI clearly pulls ahead on paper is the electronics. Bluetooth 5.4 is a generation newer than IHAO's 5.2, and MZYMI lists improved range, lower latency and more efficient power use. The frequency range is stated as 20 Hz to 20,000 Hz with a 12 mm driver and 20 ohm impedance. There's also a battery story here that IHAO simply doesn't tell: 10 hours on a single charge, up to 56 hours with the charging case, and a 10-minute quick charge that gives you 2 hours. The package includes a charging station and eartips, and wireless charging is supported.
Controls are push-button and touch, covering music and call handling. The sheet also lists active noise cancellation as a noise-control feature, which is unusual in an open-ear design and worth treating as a spec claim rather than a promise of silence — open-ear sets by nature let outside sound in.
Who should buy it? Cyclists who do long rides, commute by bike several days a week, or ride in changeable weather and want the reassurance of a case and a stated runtime. The clip-on format also suits riders who find headbands awkward under a helmet or who want to wear one bud at a time. The lighter 5.2 g per side is a real advantage on multi-hour efforts.
Side-by-Side: Which Should You Choose?
• Best for battery certainty → MZYMI Open Ear Earbuds. 10 hours per charge and up to 56 hours with the case beats an unstated runtime.
• Best for the simplest ride setup → IHAO Air Conduction. One band, one piece, nothing to clip on twice.
• Best for newer wireless tech → MZYMI Open Ear Earbuds. Bluetooth 5.4 versus 5.2, with MZYMI citing reduced latency and better power efficiency.
• Best for multi-device pairing → IHAO Air Conduction. IHAO states it can connect to two devices at once.
• Best for long-distance and multi-ride weeks → MZYMI Open Ear Earbuds. The case plus quick charge means less mid-week charging anxiety.
• Best for riders who dislike anything in the ear → either. Both are genuinely open-ear; IHAO rests on the cheekbones, MZYMI clips to the outer ear.
• Best for helmet and glasses wearers → MZYMI Open Ear Earbuds. Two small clips are usually easier to position around straps and temples than a band.
• Best for minimal parts to lose → IHAO Air Conduction. No case, no eartips, no second earbud.
• Best for water resistance → a tie. Both are rated IPX5 for sweat and rain.
In my opinion, the MZYMI Open Ear Earbuds are the better buy for most cyclists, and it comes down to one thing: information. I know it gives me 10 hours per charge, up to 56 hours with the case, a 10-minute top-up for 2 hours, Bluetooth 5.4 and a 5.2 g per-side fit. That's a complete picture for planning long rides and back-to-back commutes. The IHAO Air Conduction is the cleaner, simpler design and I'd happily recommend it to riders who want one piece and a two-device connection, but the missing runtime figure makes it harder for me to plan around. Check the current price on Amazon before you decide — that's the one variable that could flip this either way.
FAQ
They use a clip-on C-bridge design at 5.2 g per side, with silicone construction that MZYMI says adapts to different ear shapes. That's a design built for movement, though how well any clip-on stays put depends on your individual ear shape.
MZYMI publishes clear figures: 10 hours per charge, up to 56 hours with the charging case, plus a 10-minute quick charge for 2 hours. IHAO doesn't state a playtime figure, so on paper MZYMI is the safer bet if battery life is your priority.
Both are rated IPX5, which covers sweat and rain. Neither is meant for swimming, and MZYMI states that explicitly on its spec sheet.
Both will connect reliably to a phone. Bluetooth 5.4 is the newer standard and MZYMI cites better range, lower latency and more efficient power use, which lines up with its longer battery claims.
