If you want open-ear comfort with a big bass driver, long battery life and clear calls for workouts, choose 1MORE Fit SE S30; if you need maximum water protection with the newer Bluetooth standard in a compact true-wireless design, choose TOZO T6.
• 1MORE Fit SE S30 — biggest strength: An open-ear hook design built around a large 14.2mm dynamic driver, four microphones, Bluetooth 5.3, IPX5 protection and up to 30 hours of total playtime with the case.
• 1MORE Fit SE S30 — biggest trade-off: The hook-style, open-ear fit sits outside your ear canal by design, so it won't give you the sealed, isolating feel of a traditional in-ear bud, and IPX5 is splash/sweat resistant rather than fully submersible.
• TOZO T6 — biggest strength: An IPX8 waterproof rating plus Bluetooth 5.4 — the highest water-resistance and the newest Bluetooth version in this comparison — in a compact true-wireless earbud.
• TOZO T6 — biggest trade-off: The data sheet is sparse on specifics like driver size, microphone count and battery life, so there's less documented detail to compare against.
• Who each pick is for: Choose the 1MORE Fit SE S30 if you want open-ear awareness, a large driver for bass, and a documented 30-hour total playtime. Choose the TOZO T6 if water protection and the latest Bluetooth version matter most to you.
The 1MORE Fit SE S30 is an open-ear sport earbud, and the spec sheet tells you a lot about its intent. The earpiece is a hook design that rests over your ear rather than sealing your canal — that's the defining trait of "open ear." If you've ever hated the plugged-up feeling of in-ears on a long run, this is the category built to fix that. You stay aware of traffic, your surroundings and your training partner while music plays.
What it does best is lean into sound and stamina. The 14.2mm dynamic driver is a genuinely large driver for a sport bud, and 1MORE pairs it with a DBB bass-enhancement algorithm to push low-end punch. On paper, that's a recipe for energetic, beat-forward audio that suits gym sessions and tempo runs. Battery is the other headline: up to 10 hours per charge and up to 30 hours total with the charging case, which is a lot of workouts between charges. Bluetooth 5.3 handles the wireless connection, with a 10-meter range, and the case recharges fully in about 2 hours.
Buy it if: you want open-ear awareness, a big bass driver, four-mic calls and a documented 30-hour total battery figure for sport.
Skip it if: you need a fully sealed, noise-isolating in-ear fit or an IPX8 rating for heavy water exposure.
TOZO T6: Who It's For
The TOZO T6 is a compact true-wireless earbud, and its calling card is durability specs. The IPX8 waterproof rating is the standout — that's the highest water-resistance level in this comparison, well beyond splash resistance. If your workouts are sweaty, you train outdoors in the rain, or you simply want earbuds you don't have to baby around moisture, IPX8 is the number that matters most here.
It also carries Bluetooth 5.4, the newest Bluetooth version between these two products. In practice that means the most current wireless standard for pairing and connection stability. The model number is listed as "T6;HA1," which reflects that this is the T6 earbud paired with TOZO's HA1 over-ear headphone in the same listing.
Here's the honest trade-off: the data sheet for the T6 is thin. There's no listed driver size, no microphone count, no battery-life figure, and no app or EQ details to compare against the 1MORE's documented specs. That doesn't mean those things are missing from the product — it means the sheet doesn't give me a number to analyze. So my read is simple: the T6's case rests on its IPX8 rating and Bluetooth 5.4, and buyers who value water protection above everything else are the natural audience.
Buy it if: IPX8 water resistance and the latest Bluetooth version are your top priorities, and you want a compact true-wireless earbud.
Skip it if: you specifically want an open-ear design, a documented bass-focused driver, or published battery and microphone figures to compare.
• Best for battery life → 1MORE Fit SE S30. Up to 10 hours per charge and up to 30 hours with the case, versus no stated figure for the T6.
• Best for water protection → TOZO T6. IPX8 beats IPX5 — it's the higher water-resistance rating of the two.
• Best for open-ear awareness → 1MORE Fit SE S30. The hook-style open-ear design leaves your canal unsealed so you hear your surroundings.
• Best for the newest Bluetooth → TOZO T6. Bluetooth 5.4 edges out the 1MORE's 5.3.
• Best for bass-focused sound specs → 1MORE Fit SE S30. A 14.2mm dynamic driver plus a DBB bass algorithm is the only detailed audio spec in this comparison.
• Best for calls → 1MORE Fit SE S30. Four embedded microphones with an AI algorithm and environmental noise cancellation is documented; the T6 sheet lists no mic detail.
• Best for customization → 1MORE Fit SE S30. The 1MORE App lets you adjust EQ modes and button functions.
• Best for a sealed, compact in-ear fit → TOZO T6. It's the true-wireless in-ear option here, whereas the 1MORE is deliberately open.
In my opinion, the 1MORE Fit SE S30 is the better-rounded pick for most people comparing these two. It gives you more documented substance to make a decision with: a 14.2mm driver, four-mic calling, IPX5, Bluetooth 5.3, app-based EQ and a clear 30-hour total battery figure — a genuinely capable sport earbud. I'd only steer you to the TOZO T6 if water protection is non-negotiable, because IPX8 and Bluetooth 5.4 are real advantages worth having. For everyone else, the 1MORE's open-ear comfort and fuller spec sheet win me over. Check the current price on Amazon before you commit, since that's the one thing that can tip a close call.
