If you want a single wired kit that covers both your old 3.5mm gear and your newer USB C phone, choose Jiunai USB C Headphone; if you need wireless freedom, all-day battery and sweat-proof earbuds for the gym, choose SRICH Earbuds.
These two products look like they belong in the same shopping cart, but they solve completely different problems. One is a wired, plug-and-play set that works with almost anything you own. The other is a modern Bluetooth pair built around battery life, water resistance and touch controls. Here's how I'd split them.
• Jiunai USB C Headphone — biggest strength: It's a 2-pack that covers both connection types, so you get one set for a 3.5mm jack and another for a USB C port, with no charging, no pairing and no battery to think about.
• Jiunai USB C Headphone — biggest trade-off: It's fully wired, so you're tethered to your device, and the feature set stays basic: 8mm dynamic drivers, an inline remote and mic, and silicone tips rather than active noise cancellation.
• SRICH Earbuds — biggest strength: A 13mm dynamic driver, Bluetooth 5.4, IPX7 waterproofing and up to 30 hours of total playtime with the charging case make it the far more flexible everyday pair.
• SRICH Earbuds — biggest trade-off: It has no jack at all, so anything without Bluetooth is off the table, and each charge only lasts around 3–4 hours before the earbuds go back in the case.
• Who each pick is for: Choose Jiunai if you want a no-fuss wired backup that works with legacy devices and never needs charging. Choose SRICH if you want a wireless daily driver for the gym, commuting and calls.
The Jiunai set is a practical answer to a very specific problem: the headphone jack disappeared, but your drawer is still full of devices that have one. The pack ships as a wired earbud kit covering both a 3.5mm jack and a USB C port, which means you can leave one pair plugged into a laptop or MP3 player and keep the other for your phone. That's the whole appeal — no adapters, no dongles, no pairing screen.
On the inside, Jiunai uses an 8mm dynamic driver. That's a modest driver size, and the brand frames it around maximising output and reducing sound loss so what you hear stays close to the original. Realistically, this is a sound signature aimed at podcasts, calls, audiobooks, YouTube and casual music rather than critical listening. The inline remote handles volume, music and phone calls, and the built-in microphone is positioned for voice chat, video calls and voice assistant activation. The magnetic earbuds snap together, which keeps them tidy in a bag, and the package includes three pairs of silicone ear tips plus a zippered carry case.
Who should buy it: anyone who wants a dependable wired pair for a work laptop, an older phone, a tablet, a handheld console or an MP3/MP4 player. It's also a sensible pick if you simply don't want to manage charging — plug in and go. Who should skip it: if you want to move around the room while listening, hate cables catching on things, or need water resistance for heavy sweating, this is the wrong shape of product for you.
The SRICH Earbuds are built around wireless convenience. Bluetooth 5.4 handles the connection, with a claimed stable range up to 15 metres and synchronised audio and video, and they work with both iOS and Android. There's no jack anywhere, so the pairing is the product — once connected, you're free to move.
The audio side is more ambitious than the Jiunai set on paper. A 13mm large dynamic driver paired with a three-layer composite diaphragm is tuned for Hi-Fi stereo: strong bass, crisp treble and detail across a 20 Hz to 20,000 Hz frequency range. ENC call noise reduction is on board for voice pick-up, and the spec sheet lists active noise cancellation as the noise control method with touch controls for operation. For calls on a busy street or a noisy office, that combination matters more than raw driver size.
Comfort and durability are the other two pillars. Each earbud weighs about 3 grams in a semi-in-ear shape, which is the kind of design you can wear for a long session without pressure building up. IPX7 waterproofing means sweat and rain aren't a concern — that's the rating that makes these genuinely gym-friendly. Battery is 3–4 hours per charge, extended to a claimed 30 hours total with the compact charging case, and the Type-C port recharges in around an hour. The package includes the earbuds, charging case, charging cable and manual, with a one-year warranty.
Side-by-Side: Which Should You Choose?
• Best for battery life → SRICH Earbuds. Up to 30 hours total with the case versus a wired pair that needs no battery at all but also gives you no freedom.
• Best for mixed old and new devices → Jiunai USB C Headphone. A 2-pack covering 3.5mm and USB C is the only one of the two that touches legacy hardware.
• Best for the gym and sweaty workouts → SRICH Earbuds. IPX7 waterproofing and 3g earbuds are designed exactly for that.
• Best for lag-free video and gaming → SRICH Earbuds. Bluetooth 5.4 with a listed 0.01 ms audio latency is the stronger spec for synced audio and video.
• Best for calls in noisy places → SRICH Earbuds. ENC call noise reduction plus active noise cancellation beats a basic inline mic.
• Best for zero setup and zero charging → Jiunai USB C Headphone. Plug in, press play, done — nothing to pair or top up.
• Best for small, light travel kit → SRICH Earbuds. A compact charging case that also stores the earbuds is easier to pocket than a wired pair plus case.
• Best for a cheap, no-risk spare pair → Jiunai USB C Headphone. Two sets in one box means one can live in a bag and one at a desk.
In my opinion, most people shopping in 2026 should buy the SRICH Earbuds. The 13mm driver, Bluetooth 5.4, IPX7 rating and 30-hour total battery make it the more capable everyday product, and it fits the way most of us actually listen — phone in pocket, moving around, taking calls. I'd only steer you to the Jiunai USB C Headphone if you specifically need a wired pair for older or jack-only devices, or you want a two-pack backup that never needs charging. If that describes you, the Jiunai set does its job well for the money tier it sits in.
FAQ
Neither is universally better — they're different categories. SRICH wins on sound hardware, battery and water resistance; Jiunai wins on device compatibility and zero setup. Pick by how you listen, not by specs alone.
Yes, that's their clear use case. IPX7 waterproofing handles sweat and rain, each earbud weighs about 3 grams, and the semi-in-ear shape is designed for a secure all-day fit.
Yes — the pack covers both a 3.5mm jack and a USB C port, so a USB C phone is fine. Just confirm which pair you're plugging in, since the two sets in the box use different connectors.
I don't quote prices here because they change often — check the current price on Amazon using the button on this page. On features alone, SRICH gives you more technology per pair, while Jiunai's two-in-one box is the better value if you need both connector types.
