If you want the longer-lasting pair with a bigger driver and a bass-boost mode for hard training sessions, choose 1MORE Fit SE S30; if you need the newer Bluetooth version, a charging case with a visible battery screen, and app-based extras like a find-my-earbuds ringtone, choose Yamdrok Open Ear Headphones.
• 1MORE Fit SE S30 — biggest strength: a 14.2mm DLC dynamic driver paired with a bass-enhancement algorithm, plus up to 30 hours of total playtime and an IPX5 rating that shrugs off heavy sweat and rain.
• 1MORE Fit SE S30 — biggest trade-off: Bluetooth 5.3 instead of 5.4, no battery display on the case, and a bulkier earhook design that some people find takes a moment to seat correctly.
• Yamdrok Open Ear Headphones — biggest strength: Bluetooth 5.4 with a low-latency chip, dual-device pairing, an LED readout on the case, and app control that includes a ringtone finder for lost buds.
• Yamdrok Open Ear Headphones — biggest trade-off: 20 hours total battery versus 30, a smaller 11mm driver, and only IPX4 water resistance — fine for rain and sweat, not for a soaking.
• Who each pick is for: pick the 1MORE if battery life and bass punch matter most; pick the Yamdrok if you want newer connectivity, multipoint switching, and a case that tells you its charge at a glance.
The 1MORE Fit SE S30 is built around two ideas: bigger sound and longer runtime. The driver is a 14.2mm dynamic unit, and 1MORE pairs it with its own bass-enhancement algorithm, so the low end is meant to hit harder than a typical open-ear design. If you run, lift, or row to bass-heavy playlists, that combination is the whole point of this model. Add the 16-ohm impedance and a dynamic driver type, and you get a pair tuned for punch rather than flat reference listening.
Where it fits less well: the Bluetooth version is 5.3, not 5.4, and there's no LED charge display on the case. Call quality runs through four microphones with an AI algorithm and environmental noise cancellation, and there's a companion app for EQ modes and button remapping. The earhook shape is a split design in black plastic, wireless only, with no headphone jack. Buy it if long battery life, bass-forward tuning, and a tougher water rating top your list. Skip it if you want the newest Bluetooth spec, multipoint pairing, or a battery readout on the case.
Yamdrok Open Ear Headphones: Who It's For
The Yamdrok NC1 leans into connectivity and convenience. Bluetooth 5.4 with the JL7016F6 chip supports dual-device pairing — phone plus laptop, say — so you can jump between a call and a playlist without repairing. Latency is quoted at 0.06 seconds, which is the kind of number that matters for gaming, streaming, and video calls where audio drifting out of sync is immediately annoying. AAC and SBC codecs cover both iOS and Android.
The design is a clip-on open-ear build with TPE hooks and an aluminum alloy frame, and each earbud is listed at 4.98 grams. The 11mm driver uses a PU-and-titanium composite diaphragm with a spatial audio mode, and the sound is described as directional — meaning it fires toward your ear rather than broadcasting to everyone nearby. There's an app for EQ presets, spatial audio toggling, game mode, and a ringtone finder for locating a misplaced bud.
Battery is the clear compromise: 5 hours per charge, 20 hours total with the case, and a 5-hour case recharge time. The IPX4 rating handles sweat and light rain but not a downpour. The LED display on the case is a genuine quality-of-life feature — you see the charge level instead of guessing. On calls, AI-powered ENC dual microphones work to suppress wind and traffic noise, which suits city running and commuting. Buy it if you want the latest Bluetooth, device switching, app control, and a case that shows its battery. Skip it if you need maximum runtime or a higher water-resistance rating.
• Best for battery life → 1MORE Fit SE S30. 30 hours total and 10 hours per charge versus Yamdrok's 20 and 5.
• Best for bass and driver size → 1MORE Fit SE S30. A 14.2mm dynamic driver with a dedicated bass-enhancement algorithm against an 11mm driver.
• Best for water and sweat resistance → 1MORE Fit SE S30. IPX5 beats IPX4 for heavy sweat, rain, and splashes.
• Best for connectivity → Yamdrok Open Ear Headphones. Bluetooth 5.4 with a low-latency chip and dual-device pairing versus Bluetooth 5.3 with single-device pairing.
• Best for gaming and video calls → Yamdrok Open Ear Headphones. The sub-0.1-second latency figure and multipoint switching make it the smoother pick for screen-based audio.
• Best for convenience features → Yamdrok Open Ear Headphones. LED charge display on the case, app EQ presets, game mode, and a ringtone finder for lost earbuds.
• Best for lighter, lower-profile wear → Yamdrok Open Ear Headphones. 4.98g per earbud with TPE hooks and an aluminum alloy frame.
• Best for iPhone and Android alike → a tie. Both are wireless, jack-free, and list compatibility across both platforms; the Yamdrok adds AAC/SBC codec support in writing.
My Verdict
The 1MORE Fit SE S30 wins clearly. It lists 10 hours per charge and up to 30 hours with the case, while the Yamdrok NC1 lists 5 hours per charge and 20 hours total.
For latency-sensitive use, yes. Yamdrok quotes Bluetooth 5.4 with a sub-0.1-second low-latency mode and dual-device pairing, which makes it the better fit for gaming, streaming, and video calls.
Both are designed for it. The 1MORE uses an earhook split design, and the Yamdrok uses clip-on TPE hooks with an aluminum alloy frame at 4.98g per earbud. Fit is individual, so seating matters.
The 1MORE Fit SE S30, at IPX5 versus the Yamdrok NC1's IPX4. IPX5 covers sweat and splashes with more margin; IPX4 handles light rain and sweat but not a soak. If price matters to you, check the current price on Amazon before deciding.
