How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a wired, ultra-light air conduction headphone you can wear while running and still hear traffic, choose GZCRDZ Type-C; if you need a wireless Bluetooth earpiece with a boom mic and marathon battery life for calls and long shifts, choose Xmenha Single Open Ear. That is the honest split. These two are both "open ear" and both leave your ear canal unblocked, but after that they go in completely different directions — one is a corded sports companion, the other is a wireless calling tool. For running specifically, the choice comes down to whether you want zero battery anxiety (GZCRDZ) or hands-free freedom (Xmenha).
• GZCRDZ Type-C — biggest strength: It is wired over USB Type-C, weighs just 18g, and its whole design point is "listen without blocking your ears" so you stay aware of horns, bells and traffic while running or cycling.
• GZCRDZ Type-C — biggest trade-off: No battery means no charging, but it also means you are tethered to a 1.3m cable and your device needs a Type-C port — no wireless range at all.
• Xmenha Single Open Ear — biggest strength: A 150mAh battery rated for up to 30 hours of total call time and 17 hours of music playback, plus a detachable noise-cancelling boom mic and dual-mic backup.
• Xmenha Single Open Ear — biggest trade-off: It is a single-ear headset, so it is built for calls and awareness, not for stereo music listening or immersive gaming.
• Who each is for: GZCRDZ is for the runner or cyclist who wants a light, always-ready wired set; Xmenha is for the driver, trucker, or remote worker who lives on calls and hates charging.
The GZCRDZ Type-C is a wired, open-ear headphone with a Type-C plug, a built-in microphone, and an 18g body. The core idea is stated plainly in its own feature list: you listen to music without blocking your ears, so you can still hear surrounding sounds. For a runner, that is the entire point — you hear the car coming, the bike bell, the person jogging up behind you. The description even frames it around hearing a car horn or a doorbell while you walk down the street.
Who should buy it? In my opinion, the runner, cyclist or outdoor walker who wants a set that is always ready, never needs a charge, and keeps them connected to the world. Who should skip it? Anyone who wants to move away from their phone, anyone whose device lacks a USB Type-C port, and anyone planning to listen in stereo for hours — this is a single wired set with a bone-conduction-style driver, not a wireless music rig. If you want the freedom of no cable, look at the Xmenha instead.
Xmenha Single Open Ear: Who It's For
The Xmenha Single Open Ear is a wireless Bluetooth earpiece built around calls. Its headline feature is a detachable professional noise-cancelling boom mic, backed by dual front and rear microphones plus noise-reduction tech aimed at blocking road noise, keyboard taps and office chatter. The smart part: if you lose or remove the detachable front mic, the rear integrated mic still keeps calls working. That is a genuinely useful backup design for someone who talks all day.
Battery is the other story. The 150mAh battery is rated for up to 30 hours of total call time and 17 hours of music playback — the kind of numbers aimed at long work shifts and frequent travel. It is a single-ear design, so it is made for one-ear awareness, not stereo immersion: the open-ear structure sits lightly outside the canal so you stay aware of your surroundings while still taking calls. The mic arm rotates 360° and the ear hook pivots 180°, so it fits either ear, and the 15g frame uses three-point support with a non-slip hold to stay put while driving or working. It auto-pairs to your last device and works with iOS, Android, tablets and Bluetooth-capable Windows laptops.
Who should buy it? The driver, trucker, delivery worker, or office and remote-call person who wants hands-free calls and rarely wants to think about charging. Who should skip it? Anyone who wants two-ear stereo music, or someone who wants a purely wired, no-charging setup. It is a calling tool first.
• Best for running and cycling → GZCRDZ Type-C. 18g, IPX4 for sweat and rain, and open-ear awareness of traffic.
• Best for battery life → Xmenha Single Open Ear. Up to 30 hours of call time and 17 hours of music playback from a 150mAh battery.
• Best for calls and noise → Xmenha Single Open Ear. Detachable noise-cancelling boom mic plus dual-mic backup.
• Best for "never charge it" simplicity → GZCRDZ Type-C. Wired over USB Type-C, so there is no battery to top up.
• Best for driving and all-day wear → Xmenha Single Open Ear. 15g, 360° rotating mic arm, 180° pivoting hook, fits either ear.
• Best for stereo music and spatial audio gaming → neither, honestly. GZCRDZ is a single wired set and Xmenha is a single-ear Bluetooth headset — if you specifically want the best spatial audio gaming headphones for running, this pair is not built for that job.
• Best for hands-free range → Xmenha Single Open Ear. It is Bluetooth wireless; GZCRDZ is tethered by a 1.3m cable.
• Best for a device with only a Type-C port and no Bluetooth → GZCRDZ Type-C. It is a wired, universally standardized Type-C plug.
For running, I would buy the GZCRDZ Type-C. My reasoning is simple: 18g, IPX4, no battery to manage, and an open-ear design that keeps you aware of traffic — that is exactly what a runner needs, and the wired connection removes charging from the equation entirely. If your priority is hands-free calls, a boom mic, and a battery rated for up to 30 hours of talk time, I would point you to the Xmenha Single Open Ear instead. Two good tools, two different jobs. Pick the one that matches how you actually use it.
how to wear air conduction headphones
Air conduction open-ear headphones sit outside your ear canal rather than inside it, so the sound travels to your ear without blocking it. On the Xmenha, the 180° pivoting ear hook and 360° mic arm adjust to either ear; on the GZCRDZ, you simply rest the open-ear set in place and let the Type-C cable hang down.
how to use air conduction headphones
Power on and pair if it is wireless — the Xmenha auto-connects to your last paired Bluetooth device. If it is the GZCRDZ, plug the Type-C connector into your device and use the touch volume control; the built-in mic handles calls, with a mute button to switch the mic off.
how to put on air conduction headphones
Keep the speaker outside the canal and let the hook or frame rest around your ear. The Xmenha uses three-point support and a non-slip hold so it stays put while driving or working; the GZCRDZ is an 18g open-ear set that sits lightly without pressing on your ear.
how to pair goodmans air conduction headphones
Pairing is brand-specific, so follow that brand's own instructions. As a general rule for Bluetooth models like the Xmenha: power on, enable Bluetooth on your phone or laptop, select the device, and it will auto-reconnect next time.
