If you want a wired, plug-and-play set that stays locked in your ears through sweaty gym sessions and never needs charging, choose Joysico USB C Earbuds; if you need to keep your ears open to traffic, coworkers and the world around you while going wireless, choose Conyat Open-Ear Headphones.
• Joysico USB C Earbuds — biggest strength: Wired USB-C plug-and-play with a secure over-ear hook, a 13mm dynamic driver, inline mic/volume controls and six pairs of eartips for a custom in-ear seal.
• Joysico USB C Earbuds — biggest trade-off: Wired only, no Bluetooth, and it refuses to work with Lightning or 3.5mm jacks, so older phones and tablets are out.
• Conyat Open-Ear Headphones — biggest strength: True wireless freedom with Bluetooth 6.0, a 40-hour battery claim and an open-ear fit that keeps you aware of your surroundings.
• Conyat Open-Ear Headphones — biggest trade-off: Open-ear design means less bass and zero passive noise blocking, so loud environments will compete with your audio.
• Pick Joysico if you're a runner, gym-goer or commuter who wants zero battery anxiety and a snug, isolating in-ear fit.
• Pick Conyat if you cycle, walk busy streets or work in an office and want your ears free while staying untethered.
The Joysico USB C Earbuds are, at their core, a wired solution built for people who are tired of babysitting a battery. You plug the USB-C connector straight into your device — an iPhone 17, 16, 15, an iPad Pro, a MacBook, a Samsung or Pixel phone, a Chromebook — and it just works. No pairing, no adapter, no "low battery" chirp halfway through a run. In my view, that simplicity is the whole pitch, and it's a genuinely appealing one for anyone who's been burned by earbuds dying at the wrong moment.
The design leans hard into sport. The over-ear hook wraps around the top of your ear so the bud stays put even when you're sweating, and there's a shirt clip in the box to keep the 130cm cord from flapping around while you move. You get ten silicone eartips and two memory-foam tips in the box — that's six pairs of options — so you can dial in the seal and isolation you actually want. The 13mm dynamic drivers push crisp, well-balanced stereo sound with decent bass and a lift in the mids and highs, and because these are in-ear, they block out a fair amount of ambient noise. That matters at a noisy gym or on a packed subway car. The inline mic and push-button controls let you take calls and skip tracks without touching your phone.
Who should buy it? Runners, joggers, hikers, lifters and treadmill users who want a cable they can trust and a fit that won't quit. Also anyone whose daily driver is a USB-C device and who'd rather spend on sound than on charging cases.
Who should skip it? If you own an older iPhone with Lightning, a phone with a 3.5mm jack, or you simply can't stand cables, this isn't your set. Note too that the volume/remote buttons don't play nicely with every laptop — Joysico explicitly says the controls won't work on some, though the MacBook Pro is listed as fine. It's also worth checking the current price on Amazon before you commit, since the page carries a live price button.
The Conyat Open-Ear Headphones take the opposite approach: cut the cord entirely and leave your ear canal wide open. Each earpiece weighs roughly 6.7g, and the ergonomic hook shape is designed to contour your ear rather than jam into it. The result is the kind of fit you can forget about — comfortable for sports, running, commuting and long days at a desk, and it won't leave your ears feeling plugged up the way in-ears can after a couple of hours.
The headline feature is the open-ear form factor itself. Because nothing seals your canal, you stay aware of your surroundings — traffic, a passing cyclist, a colleague asking a question, a boarding announcement. That's a real safety and practicality argument if you run or ride near roads, or if you work somewhere you can't afford to be acoustically sealed off from the world. Conyat pitches it for exactly those situations, plus video calls and streaming.
On the wireless side, Conyat uses Bluetooth 6.0 for quick pairing and a stable, low-latency connection, and the buds auto-pair when you lift them out of the charging case. The claim is up to 40 hours of playtime with the case, which is a wildly different experience from a wired set — no cable to snag, no port to occupy, and a case that tops them up on the go. There's an ENC mic for calls, the earpieces are a dark blue finish, and the box includes the two earpieces, a USB-C charging cable, a portable charging box and a manual. Conyat backs it with a 30-day unconditional refund and a 2-year warranty.
Who should buy it? Cyclists, urban runners, walkers, delivery riders, office workers and anyone who wants music without shutting the world out — and anyone who's already sick of wires.
Who should skip it? If you want deep, thumping bass or serious noise isolation on a flight or a loud train, open-ear is the wrong tool. Nothing blocks sound, so the environment will bleed into your music, and you'll hear less low-end than an in-ear set delivers. And if you're on a device that isn't Bluetooth-capable, you're out of luck.
• Best for battery-free reliability → Joysico USB C Earbuds. Wired means no charging case, no runtime to manage, no dead earbuds mid-run.
• Best for all-day wear comfort → Conyat Open-Ear Headphones. At about 6.7g per earpiece and with an unobstructed ear canal, they're built to be forgotten.
• Best for noise isolation → Joysico USB C Earbuds. The in-ear seal and multiple eartip sizes actively block ambient noise; the Conyat design deliberately does the opposite.
• Best for situational awareness and safety → Conyat Open-Ear Headphones. Open-ear lets traffic and surroundings in, which matters when you run or ride near roads.
• Best for bass and a full in-ear sound → Joysico USB C Earbuds. 13mm dynamic drivers with emphasis on mids and highs in a sealed ear give you more low-end presence than an open design can.
• Best for wireless freedom and long playtime → Conyat Open-Ear Headphones. Bluetooth 6.0 with auto-pairing and up to 40 hours with the case.
• Best for USB-C-only devices and zero pairing hassle → Joysico USB C Earbuds. Plug into an iPhone 15 or later, iPad, MacBook, Samsung or Pixel and you're listening immediately.
• Best for gym and sweat-heavy workouts → Joysico USB C Earbuds. The over-ear hook plus shirt clip is purpose-built to stay put when things get sweaty.
If I had to pick one for myself, I'd take the Joysico USB C Earbuds — but only because my own use case is gym and treadmill work on a USB-C phone, where a secure in-ear fit, real noise isolation and never thinking about a battery win the day. The 13mm drivers, the over-ear hook and the six pairs of tips make it a genuinely practical sport set.
That said, I'd recommend the Conyat Open-Ear Headphones without hesitation to anyone who runs or rides near traffic, works in an open office, or simply can't stand cables. In my opinion, the choice comes down to one question: do you want your ears sealed and your cable plugged in, or open and wireless?
Neither is universally better — they solve different problems. Joysico wins on isolation, bass presence and battery-free reliability; Conyat wins on comfort, wireless freedom and staying aware of your surroundings. Pick based on how you'll actually use them.
Yes, with USB-C iPhones — the 17, 17 Pro, 16, 16e, 15 series and iPhone Air are listed as compatible, along with USB-C iPads and MacBooks. They will not work with Lightning iPhones or any 3.5mm jack.
Conyat states up to 40 hours of playtime using the included charging case, though real-world results depend on volume and use. Joysico, being wired, has no battery at all.
For extended sessions, the Conyat's ~6.7g open-ear design is likely the more comfortable pick since nothing enters your ear canal. Joysico counters with soft over-ear hooks and six eartip options, which suits people who prefer a snug, isolating fit.
Both are worth checking against their current price on Amazon, since that's what really decides value. If you want no charging and a secure sport fit, Joysico covers the essentials; if you want wireless freedom and up to 40 hours of playtime, Conyat gives you more features for the trade-off of less isolation.
