If you want a sweat-proof open-ear sports pair with marathon-grade battery life and a secure earhook fit, choose 1MORE Fit SE S30; if you need a smart touchscreen charging case with built-in AI translation and active noise cancelling for travel and commuting, choose ONES MusPlayE AI.
• 1MORE Fit SE S30 — biggest strength: Open-ear earhook design with IPX5 water resistance and up to 30 hours of total playtime, built for workouts and long sessions.
• 1MORE Fit SE S30 — biggest trade-off: Open-ear means no active noise cancelling, so it does not seal out the world — that's the point, but it isn't for quiet-focus listening.
• ONES MusPlayE AI — biggest strength: A touchscreen charging case plus AI translation and chat features, with Hybrid ANC rated up to -29dB.
• ONES MusPlayE AI — biggest trade-off: Shorter battery life (about 5 hours per charge, 24 hours with the case) and an in-ear fit you need to be comfortable with.
• Who each pick is for: 1MORE Fit SE S30 for runners, gym-goers and cyclists who want awareness plus stamina; ONES MusPlayE AI for commuters, travelers and language learners who want smart controls and noise blocking.
The 1MORE Fit SE S30 is unapologetically a sports product. The earhook shape and open-ear placement mean the earbuds sit outside your ear canal rather than plugging it, so you keep ambient awareness while you run, lift or ride. The enclosure is plastic, the color is black, and everything about the build reads as "practical" rather than "premium jewelry." For anyone who has ever had a bud pop loose mid-sprint, that hook design is the whole argument.
Where it earns its keep is stamina. The spec sheet lists up to 10 hours of playtime on a single charge and up to 30 hours total with the wireless charging case, with a 2-hour charge time. That's a lot of sessions between trips to a cable. The 14.2mm dynamic driver is on the larger side for this category, paired with a DBB bass enhancement algorithm, so the low end is clearly a priority — useful when you want motivation rather than critical listening. Bluetooth 5.3 and a 10-meter range cover normal phone-in-pocket or gym-bag use.
The call side is handled by four microphones with an AI algorithm and environmental noise cancellation, which is the realistic setup for open-ear buds: your voice comes through, but you're not getting isolation. IPX5 means sweat, rain and splashes are fine — not swimming, not showering. The 1MORE App lets you adjust EQ modes and reassign the touch controls, which matters here because touch controls on open-ear buds are easy to misfire during movement. Buy it if you train outdoors or in a gym and want to hear traffic, teammates or your surroundings. Skip it if you mainly want to disappear into music on a plane or in a noisy office — open-ear simply won't do that.
The ONES MusPlayE AI goes the opposite direction: it packs features into the case. The headline is a smart touch display on the charging case itself. You can skip tracks, answer calls, pause playback, adjust volume and switch noise-cancellation modes without pulling out your phone. If you've ever fumbled for your phone with wet or gloved hands, that's a genuinely useful design choice — and it's the kind of feature that separates this from a generic in-ear bud.
Then there's the AI layer, which is the real differentiator. The earbuds include a built-in AI translator for real-time conversation across multiple languages, and pairing with the companion app unlocks AI Chat and dialogue features covering information search, schedule management and everyday Q&A. There's also a wallpaper-generation gimmick — you can put a photo of your pet or family on the case display. It's a fun extra, but the translation and voice-assistant functions are the parts that would actually change how you use these day to day.
On audio and noise, the specs are concrete: Hybrid ANC rated up to -29dB, ENC call technology with dual mics and AI, six preset EQ modes plus three custom slots, a 13mm dynamic driver, 32-ohm impedance, 20Hz–20kHz frequency response, and 50ms latency — that last number matters if you watch video or game. Bluetooth 5.4 with a 33-foot range is the newer, more stable spec here. The catch is battery: about 5 hours per charge and 24 hours total with the 360mAh case, which charges in 1.5 hours. The fit is half in-ear, so isolation depends partly on the seal. Buy it if you commute, travel, take calls and want the case to be a control center. Skip it if you need all-day battery or you hate in-ear pressure.
Side-by-Side: Which Should You Choose?
• Best for battery life → 1MORE Fit SE S30. Up to 30 hours total versus about 24 hours, and 10 hours per charge versus roughly 5.
• Best for noise blocking → ONES MusPlayE AI. Hybrid ANC up to -29dB and an in-ear design; the S30 is open-ear by design and has no ANC.
• Best for travel and language barriers → ONES MusPlayE AI. Real-time AI translation and AI Chat are features the S30 simply doesn't offer.
• Best for phone-free control → ONES MusPlayE AI. The touchscreen case handles playback, volume and ANC modes without your phone.
• Best for staying aware of your surroundings → 1MORE Fit SE S30. Open-ear placement keeps traffic, voices and gym noise audible.
• Best for bass-forward workouts → 1MORE Fit SE S30. A 14.2mm driver with a dedicated bass enhancement algorithm is the bigger low-end setup.
• Best for low-latency video → ONES MusPlayE AI. A rated 50ms latency and Bluetooth 5.4 make it the safer pick for syncing audio to picture.
If I had to pick one for myself, I'd take the 1MORE Fit SE S30 — but only because my priority is training and I value the open-ear awareness and the 30-hour total runtime more than smart features. In my opinion, the ONES MusPlayE AI is the better buy for most people who aren't athletes: the touchscreen case, AI translation and -29dB ANC deliver more day-to-day utility for commuting and travel. Decide based on your routine, not on specs alone, and check the current price on Amazon before you commit.
For running, yes — in my opinion. IPX5 water resistance, earhook stability and up to 30 hours of playtime fit training better. The ONES is built around commuting and travel features instead.
Correct. The ONES lists Hybrid ANC rated up to -29dB plus ENC call noise reduction. The 1MORE Fit SE S30 is open-ear with environmental noise cancellation for calls only — it's designed to let outside sound in.
The 1MORE Fit SE S30 gives about 10 hours per charge and up to 30 hours with the case. The ONES MusPlayE AI gives roughly 5 hours per charge and about 24 hours with its 360mAh case.
It depends what you count as value. If you want battery, water resistance and a secure sports fit, the S30 wins on those terms. If you want a touchscreen case, AI translation and active noise cancelling, the ONES offers more features per dollar. Check the current price on Amazon for both before deciding.
