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, plug-and-play open-ear headphone that never needs charging and works with almost any USB-C device, choose COOYA USB C Open; if you need a wireless, sweat-resistant set with a charging case and long battery life for running and the gym, choose HAUSBELL Open Ear.
• COOYA USB C Open — biggest strength: wired USB-C plug-and-play with a built-in DAC, inline volume and mic controls, plus a rotatable silicone earhook — no battery to manage, ever.
• COOYA USB C Open — biggest trade-off: with no battery and no Bluetooth, you're tethered to your device by a cable, and there's no active noise cancellation.
• HAUSBELL Open Ear — biggest strength: up to 10 hours per charge plus roughly 70 more in the wireless charging case, IPX5 sweat resistance, and Bluetooth 6.1 with a 15-meter range.
• HAUSBELL Open Ear — biggest trade-off: it needs charging and pairing, and the touch controls won't suit everyone.
• Pick COOYA USB C Open if you want a cable-locked, always-ready headset for calls, study and travel.
• Pick HAUSBELL Open Ear if you want freedom of movement for running, cycling and long gym sessions.
The COOYA USB C Open is, at heart, a simplicity play. It connects through a USB-C plug and runs off your device's power, so there's no battery to top up and no pairing routine. The specs list a built-in digital DAC chip, which is the part that turns a digital USB-C signal into clean analog audio — that's why plug-and-play works across such a wide spread of hardware, from iPhone 15 and 16 models to Samsung Galaxy S25 and S26 families, iPads, MacBooks, Surface devices, OnePlus phones and Pixel handsets. If you've ever plugged a cheap USB-C dongle into a phone and gotten silence, the DAC is exactly the component that avoids that problem.
The design is an open-ear hook with a rotatable silicone earhook, and the whole thing is wired. The driver is a 15 mm dynamic unit with 32 ohm impedance, 105 dB sensitivity and a 20 Hz–20,000 Hz frequency range — a fairly sensitive, easy-to-drive spec, which matters because a wired headset leans entirely on your device's output. Inline controls cover volume plus play/pause and track skipping, and there's a microphone with a small clip so you can park it where you want during calls. A zipper carry case is included, which is a genuinely useful addition for something you'll toss in a bag.
One practical note worth flagging from the data sheet: on MacBooks you may need to go into Settings → Sound → Input/Output and manually select the USB device before audio routes correctly. It's a one-time setup step, not a flaw, but it's the kind of thing that makes people think a wired set is broken.
HAUSBELL Open Ear: Who It's For
The HAUSBELL Open Ear is built around movement and time away from a wall outlet. The headline number is the battery: 10 hours on a single charge plus about 70 more in the wireless charging case, with a 45-minute charge time. That's roughly an 80-hour total buffer, which reframes what this product is — a set you can take on a two-week trip or a string of long flights without hunting for a charger. It connects over Bluetooth 6.1 with a 15-meter range, so you can leave your phone on a bench and walk around a gym floor.
The physical design is an open-ear hook with soft flexible silicone earhooks that mold to the ear's curve. The brand specifically calls out comfort for people who wear glasses, which is a real friction point for hook-style headphones — arms of glasses and arms of earhooks fight for the same real estate. The audio side uses 14.2 mm dynamic drivers, larger than the COOYA's 15 mm is not a comparison worth making in the other direction, but 14.2 mm is a substantial driver size for this category, and HAUSBELL claims directional sound technology to limit leakage plus noise-reducing mics for calls. The enclosure is IPX5, meaning it shrugs off heavy sweat and light rain — the spec that makes it a gym product rather than a desk product. There's also a companion app with 165-language translation and no subscription, positioned as a travel backup rather than a headline feature.
Controls are touch-based, and the spec sheet lists no noise control — worth noting, because "noise-reducing mics" refers to call clarity, not to blocking the world out. That's consistent with the open-ear philosophy: you hear traffic, cyclists and office chatter on purpose.
Who should buy it: runners, cyclists, gym-goers, hikers, frequent flyers, and glasses wearers who've given up on earhooks that press. Who should skip it: anyone who wants zero charging overhead, people who dislike touch controls, and buyers who want a cable-locked connection that can't drop. And if you're comparing the two packages, note this is a wireless set with a charging case — a fundamentally different day-to-day routine.

If I had to pick one, I'd buy the HAUSBELL Open Ear for an active lifestyle and the COOYA USB C Open for a desk-and-commute one. The deciding question isn't which is "better" — it's whether you want to be tethered or charged. Wired means never thinking about power; wireless means never thinking about a cable. In my opinion, the HAUSBELL's 80-hour total battery, IPX5 rating and glasses-friendly earhooks make it the more versatile everyday pick for anyone who moves, while the COOYA wins outright for anyone who wants plug-in-and-go reliability on a laptop or phone. Match it to your routine and you'll be happy either way.
FAQ
No — it's a wired USB-C headphone powered by your device, so there's no battery to charge. The HAUSBELL, by contrast, charges in about 45 minutes and gives around 10 hours per charge plus roughly 70 more from its case.
Both handle calls, but differently. The COOYA uses an inline microphone with a clip and works the moment you plug in. The HAUSBELL uses noise-reducing mics over Bluetooth 6.1, which is more convenient if you're moving around, though it depends on a charged battery.
HAUSBELL specifically designs its earhooks for comfort with glasses, so it's the safer bet if you wear them daily. The COOYA's rotatable silicone hook is adjustable too, but it's a wired hook design rather than one marketed around glasses wear.
Both are worth checking against the current price on Amazon, since that's where the real difference will show up for your budget. My advice: decide on wired versus wireless first, then compare the live prices for the model that fits your routine.
