If you want the lighter, simpler everyday earbud with an in-ear seal and a lower-key design, choose SGNICS AGM G2; if you need longer playback, a stronger IP rating, and ear-hook stability for workouts, choose Matast Earbuds.
• SGNICS AGM G2 — biggest strength: A straightforward in-ear earbud with 13mm drivers, Bluetooth 5.3, touch control, and 31 hours of total battery life with the case. Light per bud (3.8g) and easy auto-reconnect.
• SGNICS AGM G2 — biggest trade-off: IPX4 only, so it handles splashes and light sweat but is not built for heavy sweat, rain-soaked runs, or anything beyond a brief splash.
• Matast Earbuds — biggest strength: 60 hours of total playback, IP7 internal waterproof coating, 14.2mm graphene drivers, Bluetooth 5.4, four-mic ENC calling, and 45° ear hooks that stay put during hard workouts.
• Matast Earbuds — biggest trade-off: The sport-first hook design and large driver mean a bulkier, more visible fit than a plain in-ear bud — it's built around the gym, not around staying discreet.
• Who each is for: SGNICS AGM G2 suits casual listeners, commuters, and anyone who wants a no-fuss in-ear bud for music and calls. Matast Earbuds suit runners, gym-goers, and people who sweat hard and want their earbuds to survive it.
The SGNICS AGM G2 is a classic in-ear true wireless earbud. It runs Bluetooth 5.3, which the spec sheet flags for lower power consumption and a stable signal out to about 12 meters — that's more than enough for leaving your phone on a desk or a counter and walking around a room. The 13mm compound diaphragm driver is the headline audio piece: a larger dynamic speaker is the kind of design choice aimed at fuller bass and more detail in the mids and highs, rather than a thin, tinny sound.
Battery is where it makes its everyday case. Each bud runs about 7 hours, and the charging case can top them up three to four times, giving a total of around 31 hours with both earbuds in use. For someone who charges the case once or twice a week and doesn't want to think about it, that's a comfortable rhythm. The 3.8g weight and in-ear placement keep it light, and the touch controls handle play, pause, answering calls, and even waking Siri without reaching for your phone.
The IPX4 rating is the honest limit here. IPX4 means it's protected against splashing water, so light rain, a sweaty commute, or a splash by the sink is fine. It is not built for submersion or soaked-through workouts. If you're the type who runs in a downpour or drips sweat for an hour, this isn't the bud for you — that's the Matast's territory. In my opinion, the SGNICS AGM G2 is the pick for casual listening, calls, and desk or commute use, and the one to skip if your priority is heavy-sweat training.
The Matast Earbuds are clearly designed around movement. The 45° flexible ear hooks are the giveaway — hooks wrap over the ear and hold the bud in place when you're bouncing through a run or shifting under a barbell, in a way a plain in-ear bud usually can't. You also get three sizes of ear tips (S, M, L) to dial in the fit, which matters for both comfort and for getting a proper seal.
The audio spec is the most aggressive of the two. Matast uses a four-sound-chamber design with 14.2mm graphene drivers, described as roughly 30% larger than conventional drivers, with a frequency range of 18Hz–25kHz. Bigger drivers plus a wide range is a recipe aimed at strong bass and clear highs. On calls, four microphones with ENC noise cancelling are cited as boosting vocal clarity and cutting external noise — useful if you take calls mid-workout or on a windy street.
Battery and water resistance are the standout numbers. Each bud gives about 8 hours, the case recharges them roughly six times for up to 60 hours total, and a 10-minute USB-C fast charge adds about 2 hours. The case has a dual LED digital display showing charge from 1% to 100%, so you know exactly where you stand. The IP7 rating — a nano-coating on the internal components — is the real difference from the SGNICS: this is built to shrug off sweat, rain, and accidental water exposure.
Bluetooth 5.4 adds faster transfer, lower power draw, and lower latency than 5.3, plus a stated range of about 15 meters. Dual-use mode lets you run both buds in stereo or take one out for mono listening. In my opinion, this is the pair for gym sessions, running, and sweaty outdoor work — and the one to skip if you want a discreet, minimal bud you barely notice.
Side-by-Side: Which Should You Choose?
• Best for water and sweat resistance → Matast Earbuds. IP7 internal coating versus the SGNICS's IPX4 splash protection. If sweat or rain is a real factor, Matast is the clear call.
• Best for workout stability → Matast Earbuds. The 45° ear hooks and three ear-tip sizes are purpose-built to stay put during intense movement.
• Best for a light, low-profile fit → SGNICS AGM G2. At 3.8g per bud with a simple in-ear design, it's the more discreet everyday option.
• Best for casual listening and calls → SGNICS AGM G2. Bluetooth 5.3, 13mm drivers, touch control, and auto-reconnect cover the basics cleanly without a sport-first design.
• Best for clear calls in noisy places → Matast Earbuds. Four microphones with ENC noise cancelling is a more call-focused setup than the SGNICS's single noise-cancelling mic.
• Best for charging convenience → Matast Earbuds. The digital LED percentage display and 10-minute fast charge are genuinely handy when you're heading out the door.
• Best for a simplified, no-frills setup → SGNICS AGM G2. Open the case and it reconnects; the controls are straightforward and the whole package is easy to live with.
If I had to pick one, I'd buy the Matast Earbuds. The combination of IP7 protection, 60 hours of total playback, ear-hook stability, and the larger graphene drivers covers more of what most people actually need from wireless earbuds — especially anyone who moves. The SGNICS AGM G2 is a fine, light everyday bud, and if you mostly listen at a desk or on a commute and want something simple, it'll serve you well. But for durability and battery, Matast wins on the numbers. Check the current price on Amazon before deciding, since budgets shift and both are worth comparing at the moment you buy.
can i wear waterproof headphones in the shower
It depends on the rating. IPX4, like the SGNICS AGM G2, only protects against splashing water, so direct shower spray isn't recommended. The Matast Earbuds carry IP7, a stronger internal nano-coating against sweat and water exposure, but even IP7 isn't the same as a fully submersible rating, so I wouldn't treat either as shower-proof.
are headphones waterproof
Most "waterproof" earbuds are actually water-resistant, not fully waterproof. IPX4 means splash-resistant, while IP7 means protected against stronger water exposure like sweat and rain. Neither of these two is rated for full submersion, so treat the rating as your guide rather than the marketing word.
which has better battery life, SGNICS AGM G2 or Matast Earbuds
Matast. Its spec sheet lists 8 hours per bud and up to 60 hours total with the case, while the SGNICS AGM G2 lists 7 hours per bud and around 31 hours total. For long days or multi-session workouts, Matast lasts noticeably longer between charges.
is Matast Earbuds good for running and gym workouts
Yes, that's what it's built for. The 45° ear hooks and three ear-tip sizes keep it secure during intense movement, and the IP7 coating resists sweat and rain. The SGNICS AGM G2's IPX4 rating and in-ear design make it better suited to lighter, everyday use.
