If you want a wired USB-C earphone with a metal build, a proper in-line remote for calls and volume, and the longest warranty of the two, choose Gennice Hi-Fi; if you need a lightweight set that ships with three sizes of silicone tips, a protective case, and a tangle-free cord for running and commuting, choose Jiunai USB C Headphones.
• Gennice Hi-Fi's biggest strength: a metal-bodied in-ear design with a built-in DAC, HD microphone, full button remote, passive noise cancellation and a 6-month warranty.
• Gennice Hi-Fi's biggest trade-off: one set of earphones in the box, so you don't get spare tips or a carry case, and the housing is heavier than an ABS plastic shell.
• Jiunai USB C Headphones' biggest strength: a practical starter kit — three sizes of silicone tips (S, M, L), a protective case, a tangle-free cord and the higher 114 dB sensitivity rating of the two.
• Jiunai USB C Headphones' biggest trade-off: a plastic ABS build and a shorter 3-month warranty, with noise handled purely by the ear tip seal rather than any dedicated noise-cancelling tech.
• Who each pick is for: Gennice Hi-Fi for people who want a sturdier, more feature-complete daily earphone; Jiunai for people who want a fit-it-to-your-ears set they can toss in a bag and take running.
Gennice Hi-Fi is the more "finished" product of the two on paper. The housing is metal rather than plastic, the driver is a 10 mm dynamic unit with a 32 ohm impedance and a 20 Hz–20 kHz frequency range, and Gennice pairs it with a built-in DAC chip that it says reduces loss during the sound transfer. In plain terms, that's the kind of design that tends to keep a wired USB-C signal clean on phones and tablets that don't have their own headphone jack. The 102 dB sensitivity figure means it doesn't need much power to get loud, which suits phones, iPads and laptops plugged in directly.
Who should buy it? If you take calls, switch tracks constantly, and want something that feels substantial — a metal shell, a real remote, and a 6-month warranty — this is the more robust pick. It also suits anyone who wants one earphone for phone, tablet and laptop rather than juggling devices. Who should skip it? If you need spare ear tips in different sizes, a carry case, or the lightest possible thing on your head for a long run, Gennice gives you one set of earphones in a retail box and not much else. And if you're rough on gear and want the smallest, lightest shell, metal adds weight you'll feel.
Jiunai USB C Headphones: Who It's For
Jiunai USB C Headphones are built around the idea that fit and convenience come first. You get a 10 mm dynamic driver here too, with the same 32 ohm impedance, but a much higher 114 dB sensitivity rating — which usually translates to an easier, louder listen straight out of a phone. Jiunai describes the tuning as crisp vocals with balanced acoustic output, aimed at calls and everyday music rather than a bass-heavy signature. The box is also the more practical one: three sizes of silicone tips (small, medium, large), a protective case, and a tangle-free cord.
That tip selection is the real feature. A snug, noise-isolating seal is what actually cuts train rumble and office chatter on a wired earphone, and being able to swap between S, M and L means you can chase that seal instead of settling for whatever fits. Jiunai's stated use cases back this up — running, busy commutes, and dialing into meetings — because a secure in-ear fit is what keeps an earphone from working loose mid-stride. The in-line remote covers volume, track control and call management, and the whole thing is plug-and-play over USB-C with no Bluetooth pairing, so there's no battery to think about and no pairing lag.
Side-by-Side: Which Should You Choose?
• Best build quality → Gennice Hi-Fi. Metal housing versus ABS plastic.
• Best fit flexibility → Jiunai USB C Headphones. Three tip sizes (S, M, L) instead of one.
• Best for calls and track control → Gennice Hi-Fi. HD mic plus a full button remote for volume, tracks and answering or rejecting calls.
• Best for running and commuting → Jiunai USB C Headphones. Tangle-free cord, secure-fit tips and a protective case for tossing in a bag.
• Best for easy loudness on a phone → Jiunai USB C Headphones. Higher 114 dB sensitivity versus 102 dB.
• Best for signal cleanliness on USB-C → Gennice Hi-Fi. Built-in DAC chip designed to reduce loss in the sound transfer.
• Best warranty cover → Gennice Hi-Fi. 6 months versus 3 months.
• Best all-rounder for mixed devices → Gennice Hi-Fi. The wider published compatibility list across iPhone, iPad, Galaxy, Pixel and more.
If I were buying one of these for myself, I'd take the Gennice Hi-Fi. In my opinion the metal build, the DAC chip, the complete remote and the doubled warranty make it the more durable, more versatile earphone for someone who uses one pair across a phone, a tablet and a laptop all day. I'd only switch to the Jiunai if fit were my number one problem — the three tip sizes and the protective case genuinely solve something Gennice doesn't address out of the box. Both are wired, both are USB-C, both use 10 mm dynamic drivers, so the decision really comes down to build and control versus fit and kit.
FAQ
Not universally — it's better built and better equipped for calls, with a metal shell, a DAC chip and a 6-month warranty. Jiunai wins on fit options, sensitivity and bundled accessories. Pick based on which of those you actually need.
Yes, both list the iPhone 15, 16 and 17 families as compatible, along with iPad and MacBook models. Gennice also publishes a longer list covering Samsung Galaxy S and Note, Z Flip/Fold and Google Pixel devices.
Jiunai, in my opinion — the three silicone tip sizes let you dial in a secure, noise-isolating seal, and the tangle-free cord plus protective case suit being thrown in a bag. Gennice's anti-knot design helps, but you only get the one set of tips.
