If you want a wired, zero-latency connection with USB-C and in-line controls that never need charging, choose iMangoo USB C Headphones; if you need true wireless freedom, all-day battery life and open-ear awareness for outdoor workouts, choose Htcmf Open Ear Earbuds.
• iMangoo USB C Headphones — biggest strength: A wired USB-C connection with a built-in DAC chip, a 16 mm dynamic driver, and a remote with volume, track and call controls. No battery, no pairing, no latency.
• iMangoo USB C Headphones — biggest trade-off: It's corded. You're tethered to your phone, and there's no wireless option and no water-resistance rating listed. It's built for USB-C devices only.
• Htcmf Open Ear Earbuds — biggest strength: Up to 9 hours per charge and up to 90 hours total with the charging case, Bluetooth 5.3, an IPX7 water-resistance rating, and an open-ear hook design that keeps your ears unblocked.
• Htcmf Open Ear Earbuds — biggest trade-off: It's wireless, so it depends on battery and pairing. There's no wired fallback, and the open-ear shape means less passive noise isolation by design.
• Who each pick is for: Choose iMangoo if you want plug-and-play wired audio for USB-C phones and laptops; choose Htcmf if you want cord-free listening with long battery life for running, cycling and the gym.
The iMangoo USB C Headphones are a wired pair built around a USB Type-C jack. There's no battery to manage and no Bluetooth pairing to fiddle with — you plug in and you're listening. That alone makes them appealing to anyone who's tired of charging yet another device.
Under the hood, iMangoo uses a 16 mm dynamic driver with a built-in DAC chip, which the spec sheet says is there to keep the high-resolution audio of your device intact without buzzing or popping. The frequency range runs the standard 20 Hz to 20,000 Hz, impedance is 16 ohm, and sensitivity is listed at 126 dB. In plain terms, that's a sensitive, easy-to-drive setup — your phone shouldn't struggle to power it.
The design is an over-ear hook style that sits outside the ear canal rather than plugging into it. The enclosure is plastic and the finish is black. Controls live on the cord: a remote for play/pause, track skipping and volume, plus a microphone for hands-free calls. The connectors are metal-plated, which the brand says reduces poor contact, and the TPE cord is described as tangle-free and reinforced to survive repeated bending. The package includes a protective case and a wire clip, and there's an 8-month warranty.
Who should buy it: Anyone with a USB-C phone or laptop who wants simple, reliable wired sound for the gym, running, commuting or desk work — and who values never thinking about battery life. The listed compatibility covers iPhone 15/16/17 models, Samsung Galaxy S and Z series, and Google Pixel devices with USB-C.
Who should skip it: If you want to move freely without a cord, or you need a water-resistance rating for heavy sweat or rain, this isn't the pick. It's also the wrong choice if your device still uses a 3.5 mm jack or Lightning — this is USB-C only.
The Htcmf Open Ear Earbuds (model O8) are a wireless pair with an ear-hook shape that rests over the ear instead of inside the canal. The brand's pitch is comfort: no pressure on the ear canal, no sealed-in feeling, and enough ambient awareness to hear traffic, training partners or coworkers while your music plays.
The headline spec is battery. You get up to 9 hours of playback on a single charge, and up to 90 hours total when you factor in the charging case. The case also has an LED power display so you can see the remaining charge and the earbuds' charging status without guessing.
Connection is Bluetooth 5.3 with a stated range of up to 33 feet, and the earbuds auto-pair when you open the case — you pick "O8" from your Bluetooth menu. Audio comes from 16.4 mm dynamic drivers covering 20 Hz to 20,000 Hz, and there's an internal microphone for calls. Controls are touch-based on the earbuds themselves.
For workouts, the ear-hook fit is designed to stay put, and the IPX7 rating means sweat and moisture shouldn't be a problem. The earbuds are black plastic, and the box includes the LED charging case, a Type-C charging cable and a manual.
Who should buy it: Runners, cyclists, gym-goers and outdoor users who want cord-free listening, long battery life and the safety of hearing their surroundings. It's also a good fit for anyone who finds in-ear buds uncomfortable over long stretches.
Who should skip it: If you want maximum isolation from background noise, open-ear design works against you — that's the point of the shape. And if you'd rather not deal with charging or pairing at all, a wired option is simpler.
• Best for battery life → Htcmf Open Ear Earbuds. Up to 9 hours per charge and up to 90 hours with the case beats a wired pair that has no battery at all.

If I had to pick one, I'd buy the Htcmf Open Ear Earbuds. In my opinion, the combination of up to 90 hours of total playtime, Bluetooth 5.3, IPX7 water resistance and the open-ear hook design makes it the more versatile everyday companion — especially if you run, cycle or train. The iMangoo USB C Headphones are the smarter choice if you specifically want wired reliability, in-line controls and never want to think about charging. But for most people juggling workouts, commutes and calls, the wireless freedom wins.
Yes. They use an ear-hook fit designed to stay in place, carry an IPX7 water-resistance rating, and the open-ear shape keeps you aware of your surroundings — all useful for running and cycling. Just note the open design means less noise isolation.
They work with USB-C devices, and the listed compatibility includes iPhone 15, 16 and 17 models along with Samsung Galaxy and Google Pixel phones that use USB-C. If your device has a Lightning port or a 3.5 mm jack, they won't connect.
The Htcmf Open Ear Earbuds, by a wide margin. They offer up to 9 hours per charge and up to 90 hours with the charging case. The iMangoo headphones are wired and don't use a battery at all — they draw power from your connected device.
