How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want an open-ear sport headphone that keeps you aware of traffic while you run, with the newer Bluetooth and the longer per-charge battery, choose ABCDONG Open Ear Headphones; if you need a single-ear, dual-mic headset you can flip between left and right for calls and driving, choose IHAO Earpiece Headphone Dual.
• ABCDONG's biggest strength: A true-wireless pair with a charging case, 60-hour total playback, Bluetooth 5.3, a 16.2mm dynamic driver and IPX6 water resistance — built for sweaty outdoor sessions.
• ABCDONG's biggest trade-off: It ships as a two-earbud set, so it isn't the pick if you specifically want a single-ear headset you can move from side to side.
• IHAO's biggest strength: A single open-ear hook with a changeable left/right design, active noise cancellation and a dual-mic setup aimed squarely at clear calls.
• IHAO's biggest trade-off: One earpiece, Bluetooth 5.0 and a 10-hour music runtime, so it's a calling tool rather than an all-day music companion.
• Pick ABCDONG if you want a stereo pair for running, cycling and commuting with maximum playback time.
• Pick IHAO if you want a hands-free single-ear headset for driving, business calls and gym sessions where one ear stays open.
The ABCDONG set is built around the idea that you should hear your music and the world at the same time. It's an open-ear, earhook-style pair — no ear cups, no buds pushed into your canal — so air can move and your ears don't get that sealed, stuffy feeling after an hour. The silicone earhooks wrap around the back of your ear, which is what keeps them from bouncing loose mid-stride.
What stands out in the spec sheet is the combination of range and runtime. The 16.2mm dynamic driver covers a 20Hz–20,000Hz frequency range, and the tuning is described as leaning into the low end. Bluetooth 5.3 gives you the newer version of the standard with a rated range up to 33 feet, and the earbuds auto-pair when you open the charging case after the first setup. Battery is the headline: roughly 30 hours of average life per charge and about 60 hours of total playback with the case, refilled in around two hours.
Who should buy it: runners, cyclists, commuters and gym-goers who want stereo sound, maximum battery and situational awareness in one package. Who should skip it: anyone who wants a single-ear headset, or who prefers the isolation of a sealed in-ear design. It's also worth noting the color is listed as light yellow rather than the "skin color" in the title — a small thing, but worth knowing before you order. As with anything, check the current price on Amazon before committing.
IHAO Earpiece Headphone Dual: Who It's For
The IHAO is a different animal entirely. This is a single-ear, open-ear headset with an earhook that you can move between your left and right ear — the "dual" in the name refers to the dual-mic design and the changeable fit, not two earpieces. If you've ever spent a long call with a headset jammed in one ear and wanted to switch sides halfway through, that flexibility is the whole point here.
The calling features are the focus. There's a CSR chip paired with intelligent noise reduction and a dual-mic array for stereo sound and clear phone talk. The spec sheet also lists active noise cancellation, which is unusual on an open-ear design and speaks to how much this product prioritizes call clarity over pure music immersion. The 40mm dynamic unit is described as delivering strong bass, and the tuning is pitched as balanced across treble, mid and bass.
The control scheme is button-based rather than voice-based: play, pause, volume, track skipping and call answering all happen from easy-to-reach physical buttons. Some people prefer that to voice commands, especially with gloves on or in a noisy car. Battery life is 10 hours of music or 15 hours of talk time per charge, with 200 hours of standby, and a full charge takes 1.5 hours. Bluetooth 5.0 handles the connection and works with iOS, Android, Mac and PC.
Who should buy it: drivers, delivery workers, business callers and anyone who wants one ear free and one ear on the conversation. Who should skip it: anyone who wants stereo music from both ears, or who needs more than about 10 hours of continuous music before recharging.
• Best for battery life → ABCDONG Open Ear Headphones. 30 hours average per charge and up to 60 hours total with the case, versus 10 hours on the IHAO.
• Best for calls → IHAO Earpiece Headphone Dual. Dual mics, intelligent noise reduction and active noise cancellation are all aimed at phone conversations.
• Best for running and cycling → ABCDONG Open Ear Headphones. IPX6 sweat and splash resistance plus wrap-around earhooks and stereo sound on both ears.
• Best for driving and work → IHAO Earpiece Headphone Dual. The single-ear open design and physical buttons make it the more practical headset for hands-free use.
• Best for newer connectivity → ABCDONG Open Ear Headphones. Bluetooth 5.3 with a 33-foot rated range is a step ahead of the IHAO's Bluetooth 5.0.
• Best for left/right flexibility → IHAO Earpiece Headphone Dual. The changeable earhook lets you wear it on either ear.
• Best for sound driver size → IHAO Earpiece Headphone Dual on paper at 40mm, though the ABCDONG's 16.2mm driver is tuned specifically for open-ear low-frequency output — bigger isn't automatically better in an open design.
• Best for all-day wear → ABCDONG Open Ear Headphones. The ultra-light, bud-free design is explicitly built to avoid ear fatigue over long working days.
In my opinion, the ABCDONG Open Ear Headphones are the better buy for most people. The stereo pair, 60-hour total playback, Bluetooth 5.3, IPX6 rating and 16.2mm driver make it the more versatile product — it handles running, commuting, gym sessions and long workdays without a recharge. The IHAO is the smarter choice only if your priority is a single-ear calling headset you can flip between ears, and you're fine trading music runtime and stereo sound for that. If you want maximum value per feature, I'd go ABCDONG.
The ABCDONG wins clearly. It's rated at about 30 hours of average life per charge with up to 60 hours of total playback using the case, while the IHAO is rated at 10 hours of music or 15 hours of talk time. For long days away from a charger, the ABCDONG is the safer pick.
No. It's a single-ear headset. "Dual" refers to the dual-mic design and the changeable earhook that lets you wear it on your left or right ear. If you want sound in both ears at once, the ABCDONG is the one you want.
The spec sheet lists IPX6 water resistance, which covers sweat and splashes. That makes it suitable for running in light rain and heavy gym sessions, though IPX6 isn't the same as full submersion, so don't swim with it. The IHAO sheet doesn't list a water-resistance rating.
The IHAO is designed for it. Dual mics, intelligent noise reduction, active noise cancellation and physical buttons for answering and ending calls all point to a headset-first product. The ABCDONG also has dual mics and a voice assistant, but it's a sport-focused stereo pair rather than a dedicated calling tool.
