If you want a traditional in-ear earbud with bigger drivers, a longer total battery figure, and a case that reconnects the moment you flip it open, choose SGNICS AGM M7; if you need an open-ear design that never seals inside your ear canal and still carries an IPX4 water-resistance rating, choose Yunseity Earbuds. Both are Bluetooth 5.3 wireless earbuds with a charging case, a built-in mic and touch controls, and both are rated IPX4 — so the real decision is about fit philosophy, not about who survives a sweaty workout. That is the whole comparison in one line, and everything below explains why.
• SGNICS AGM M7 — biggest strength: 13mm dynamic drivers plus a stated 31 hours of total playtime (7 hours per charge, with the case topping the buds up 3–4 times).
• SGNICS AGM M7 — biggest trade-off: It is a sealed in-ear design, so you have to be comfortable with a tip sitting in your ear canal, and the 31-hour figure only applies when both buds are used together.
• Yunseity Earbuds — biggest strength: A fully open, non-inserting design that rests at the ear rather than plugging it, so there is no pinching sensation and you stay aware of traffic, gym announcements and coworkers.
• Yunseity Earbuds — biggest trade-off: The case only recharges the buds a bit more than twice, and the open fit means you give up the passive noise blocking a sealed tip gives you for free.
• Who each pick is for: SGNICS AGM M7 for people who want a conventional in-ear bud with more driver surface and longer case-backed runtime; Yunseity Earbuds for people who dislike things inside their ears and want to hear the world while they train.
The AGM M7 is the more conventional product of the two. It is an in-ear TWS earbud built around a 13mm compound diaphragm dynamic driver, which is a large driver for this category — the kind of spec that usually translates into a fuller low end and more texture in the midrange rather than a thin, tinny signature. Each bud weighs about 3.8g, so the in-ear fit is meant to be light enough to disappear during a commute or a long call. The enclosure is ABS+PC plastic in black, and it ships with a cable, ear cushions and a user manual in the box.
Battery is where the AGM M7 makes its strongest case. SGNICS states 7 hours of playback per charge and a case that can refill the buds 3–4 times, for a total of 31 hours when both earbuds are worn at once. In practice that is the difference between charging every night and charging every few days — a real convenience if you wear buds at a desk all week and only top up the case on weekends. The Bluetooth 5.3 chip is described as lower-power and more stable, with a working range of about 12 meters, and pairing is deliberately low-effort: open the case and it reconnects to the last device automatically, with manual pairing needed only the first time.
The controls are touch-based, covering call answering, playback and waking a voice assistant. There is also an ENC microphone setup, meaning the mic array is aimed at reducing background noise on your voice during calls rather than at cancelling noise for your ears — worth knowing, because this is not an active noise cancelling headphone. I would point a buyer toward the AGM M7 if they want an everyday in-ear bud for music, calls and video with the longest case-backed runtime in this matchup. I would steer them away if they hate the feeling of silicone tips in their ears, or if they specifically want to hear their surroundings while running outdoors — a sealed in-ear design works against you there.
The Yunseity Earbuds take the opposite approach. This is an open-ear design: the buds sit at the ear and let sound surround it rather than sealing the canal, which the brand describes as a more three-dimensional presentation. The practical benefit is comfort and hygiene. Nothing is inserted, so there is no pinching sensation and none of the pressure or wax-related irritation that long-term in-ear wearers sometimes run into. If you have ever taken a bud out after two hours and been glad to, this is the design that solves your problem.
Water resistance is the other headline. The Yunseity Earbuds carry an IPX4 rating, which is the same rating the AGM M7 claims, so both are built to shrug off sweat, light rain and splashes during a workout, run, ride or commute. The brand's own guidance is sensible and worth repeating: IPX4 means splash and sweat resistant, not submersible, so do not drop them in a pool or rinse them under a tap if you want them to keep performing. The open design also means you keep situational awareness — you can hear a car behind you on a run, a colleague calling your name, or a boarding announcement.
Runtime is more modest but still practical. Yunseity states the buds deliver over 10 hours of use once fully charged, recharge in under an hour, and that the case can refill them more than twice. Touch controls handle volume and track skipping directly on the bud, so you can adjust without pulling out your phone. I would recommend the Yunseity Earbuds if you want an open, all-day-comfortable bud for workouts, cycling, walking and working while staying aware of your surroundings. I would skip them if your priority is maximum total battery from a case, or if you want the passive isolation and deeper bass that a sealed in-ear fit provides.
• Best for total battery life → SGNICS AGM M7. A stated 31 hours total versus roughly 10 hours per charge plus a little over two case refills on the Yunseity.
• Best for call clarity → SGNICS AGM M7. It is the one of the two that specifically lists an ENC noise cancelling mic for voice pickup.
• Best for ear comfort over long sessions → Yunseity Earbuds. The open design never enters the ear canal, so there is no pinching or pressure build-up.
• Best for outdoor training and awareness → Yunseity Earbuds. Open fit plus IPX4 means sweat protection without cutting you off from traffic and surroundings.
• Best for bigger-driver sound → SGNICS AGM M7. A 13mm compound diaphragm driver is a larger, fuller spec than an open bud can typically offer.
• Best for fast top-ups → Yunseity Earbuds. A full charge in under an hour is stated for the buds.
• Best for simple pairing → SGNICS AGM M7. Open the case and it reconnects automatically to your last device, with manual pairing only on first use.
• Best for people who dislike in-ear plugs → Yunseity Earbuds. That is the entire point of the design, and it is the clearest dividing line between these two.
In my opinion, the SGNICS AGM M7 is the better buy for most people, because the 13mm drivers, the 31-hour case-backed runtime and the ENC mic cover the three things an everyday wireless earbud buyer actually notices: sound, charging frequency and call quality. I would only switch to the Yunseity Earbuds if wearing something inside my ear canal is the dealbreaker — and for runners, cyclists and anyone who works with buds in all day, that is a legitimate dealbreaker. Both are IPX4, so if the deciding factor in your head is water resistance alone, they are on equal footing and the fit should decide it. If budget matters to you, check the current price on Amazon for each before committing, since that is the one variable I cannot compare here.
FAQ
can i wear waterproof headphones in the shower
are headphones waterproof
Almost none are truly waterproof, and neither of these two is. Both the SGNICS AGM M7 and the Yunseity Earbuds are rated IPX4, which means water resistant to splashes and sweat rather than watertight. Treat them as workout-safe, not swim-safe.
what's the difference between these two earbuds if both are IPX4
The water rating is the same; the fit is not. The AGM M7 is a sealed in-ear bud with 13mm drivers, a 31-hour total battery figure and an ENC mic, while the Yunseity Earbuds are open-ear, never entering the canal, with over 10 hours per charge and a case that refills them more than twice.
do open ear earbuds stay in during a run
That is the design goal of the Yunseity Earbuds — the buds rest at the ear instead of plugging it, so there is no pinching and nothing to work loose from canal pressure. Combined with IPX4 sweat resistance and an under-one-hour charge time, they are built with exercise in mind.
