How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want active noise cancellation, a sealed in-ear fit and hands-free AI assistance on Galaxy devices, choose SAMSUNG Galaxy Buds 3; if you need an open-ear design that keeps you aware of traffic, survives sweat and rain, and runs for days between charges, choose DEMICEA Gen 2. Both are true wireless earbuds, but they solve two completely different problems — one blocks the world out, the other lets it in on purpose.
• SAMSUNG Galaxy Buds 3 — biggest strength: Active Noise Cancellation plus an 11mm dynamic driver, with Ambient mode as the escape hatch when you want to hear what's around you.
• SAMSUNG Galaxy Buds 3 — biggest trade-off: It's an in-ear bud with a rated 18 hours of battery life, and it's built to live inside the Galaxy ecosystem rather than outside it.
• DEMICEA Gen 2 — biggest strength: A bone conduction, open-ear hook design rated IP68 with up to 60 hours of total playtime with the case — nothing goes inside your ear canal.
• DEMICEA Gen 2 — biggest trade-off: No noise cancellation at all, and an open-ear design means you'll always hear your environment, for better and for worse.
• Who SAMSUNG Galaxy Buds 3 is for: commuters, call-heavy users and Galaxy phone, Tab or PC owners who want quiet and a secure sealed fit.
• Who DEMICEA Gen 2 is for: runners, cyclists, gym-goers and anyone who wants long battery, water resistance and full situational awareness.
The Galaxy Buds 3 is built around one idea: control what you hear. Active Noise Cancellation cuts down outside noise, and when you'd rather stay aware — crossing a street, waiting for a platform announcement — you flip to Ambient mode. That toggle is the whole personality of this product. It's an in-ear bud with a plastic enclosure in Gray, a dynamic driver running a 20 Hz to 20,000 Hz frequency range, and a bigger 11mm speaker tuned for deep bass. For daily commutes and weekend playlists, that's the formula most people actually want.
Calls are clearly a priority here. Samsung added a microphone and enhanced background noise reduction, so you can hear and be heard on the phone rather than shouting into a windy street. Battery life is rated at 18 hours, and recharging is quick when you finally run it down. Everything is controlled by touch: a pinch to play, pause or answer, and a swipe on the blade to change volume. No hunting for buttons with gloves on.
The ecosystem angle matters more than the spec sheet suggests. The Buds 3 pair and automatically switch between Galaxy devices — phone to Tab to PC — as your attention moves. There's also hands-free Gemini access, so you can ask for things without pulling out your phone. If your life is already Samsung-shaped, that's a real convenience.
Buy it if you want noise cancellation, a sealed fit, clear calls and voice-assistant access on Galaxy hardware — and you're fine charging more often than once a week. Skip it if you can't wear in-ear buds comfortably, you need to stay fully aware of your surroundings, or you need heavy water and sweat protection for outdoor training. The Buds 3 ships with ear tips in S, M and L plus a charging station, and carries a 2-year manufacturer warranty.
The DEMICEA Gen 2 goes the opposite direction — it never enters your ear canal. This is an open-ear, bone conduction hook design, so your ears stay open to traffic, teammates and training partners while audio travels through bone rather than a sealed canal. For running, cycling, yoga and gym work, that's not a compromise; that's the point. Nothing blocks a car horn, and nothing gets itchy after an hour.
The upgrades are practical rather than flashy. The ear-contact surface moved to liquid skin-friendly silicone, which the brand says reduces wearing pressure by 40% compared to the previous generation's hard plastic while adding friction so the hooks stay put. Bluetooth jumped from 5.3 to 6.0 with an ultra-fast instant link chip — open the case and it connects, roughly twice as fast as before. A 15mm bone conduction driver with 8 ohm impedance and 86 dB sensitivity handles the audio, and a ToneTerra system is claimed to add 30% more volume than the previous generation, paired with SonicBoost 2.0 for bass and highs.
Battery is where this thing runs away with it. Up to 15 hours of continuous listening on a charge, and the case adds four more full charges for a rated 60 hours total. A five-minute top-up buys an hour of playback, and a full charge takes about 2.5 hours. IP68 means sweat, rain and a rinse under the tap are all fine — genuinely useful if you train outdoors. Dual EQ modes let you switch between Music mode for bass-forward workouts and Reading mode for a softer, vocal-focused profile that won't fatigue your ears during long audiobook or podcast sessions.
Buy it if you train outdoors, hate things inside your ears, or want a week of power without thinking about a charger. Skip it if you fly often, work in loud open offices, or simply want music to drown out the world — there's no noise cancellation here, and open-ear means you'll always hear your environment.
• Best for blocking out noise → SAMSUNG Galaxy Buds 3. Active Noise Cancellation with an Ambient mode switch is the core feature.
• Best for staying aware of your surroundings → DEMICEA Gen 2. Open-ear bone conduction keeps your canal clear by design.
• Best for battery life → DEMICEA Gen 2. Up to 60 hours total with the case versus 18 hours rated on the Buds 3.
• Best for workouts, sweat and rain → DEMICEA Gen 2. IP68 protection and a hook fit that won't fall out mid-run.
• Best for phone calls → SAMSUNG Galaxy Buds 3. The added microphone and enhanced background noise reduction are aimed squarely at voice.
• Best for Galaxy owners → SAMSUNG Galaxy Buds 3. Automatic switching between phone, Tab and PC, plus hands-free Gemini.
• Best for all-day comfort without ear fatigue → DEMICEA Gen 2. Soft silicone contact surfaces and nothing inserted into the ear.
• Best for voice content like audiobooks → DEMICEA Gen 2. Reading mode is tuned specifically for vocal frequencies.
In my opinion, the DEMICEA Gen 2 is the pick for most people who'd describe themselves as active — runners, cyclists, gym regulars. The open-ear design, IP68 rating and up to 60 hours of total playtime cover the three things that actually break cheap earbuds: sweat, fit and charging anxiety. I'd choose the SAMSUNG Galaxy Buds 3 instead if my day revolves around commuting, calls and Galaxy devices, because noise cancellation and voice pickup are worth more there than battery headroom. Decide which of those two lives sounds like yours, then check the current price on Amazon before you commit.
