How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a familiar true wireless earbud with active noise cancellation, voice control and a sealed in-ear fit, choose Samsung Galaxy Buds 3; if you need an open-ear design that stays put through sweat and rain with marathon-grade battery life, choose DEMICEA Gen 2. That is the whole decision in one line. Everything below is just the reasoning behind it.
• Samsung Galaxy Buds 3 — biggest strength: Active Noise Cancellation in a compact in-ear bud, with voice control for music, volume and hands-free assistant use. Bluetooth 5.4 and a 30-hour battery figure round out a very "everyday commute" package.
• Samsung Galaxy Buds 3 — biggest trade-off: It is an in-ear, sealed design. That means it blocks outside noise (a plus on a plane, a minus if you need to hear traffic, a coach or a running partner). It also lists no water-resistance rating in its specs, so I would not treat it as a training partner.
• DEMICEA Gen 2 — biggest strength: Open-ear bone conduction with an IP68 waterproof rating, up to 60 hours of total playtime with the case, and Bluetooth 6.0 with a fast-pairing chip. It is built for movement.
• DEMICEA Gen 2 — biggest trade-off: No noise cancellation at all, and by design it does not seal your ear canal, so bass and isolation will never match a good in-ear bud. It is also a heavier, hook-style object on your head.
• Who each is for: Samsung Galaxy Buds 3 for desk, commute, calls and quiet listening; DEMICEA Gen 2 for running, yoga, cycling and anyone who wants to stay aware of their surroundings.
Samsung's Galaxy Buds 3 is the "classic" answer to true wireless. It sits in your ear canal with silicone tips, and the spec sheet leads with exactly the thing that matters in that format: Active Noise Cancellation. Outside noise is the problem it is designed to solve, and it solves it passively (by sealing) and actively (by cancelling). If you work in an open office, ride a train, or just want your podcast to win the fight against a noisy street, that is the core value here.
The rest of the sheet is built around daily convenience. Bluetooth 5.4 is the modern standard and should pair reliably with phones and laptops. Volume and playback are handled by voice control, and the feature list calls out hands-free assistant access plus a translation feature that pipes interpreted speech into your ear. A 16-ohm impedance and a dynamic driver covering 20 Hz to 20,000 Hz is a standard full-range setup — nothing exotic, but the right shape for general music and spoken word. The 30-hour battery figure is the total with the charging case, which in practice means roughly a week of commutes between charges for most people.
DEMICEA Gen 2: Who It's For
The DEMICEA Gen 2 is a different animal entirely. It is an open-ear, bone conduction headphone — the driver is a bone conduction unit, not a speaker aimed into your ear canal. That single design choice explains everything else on the sheet. Because nothing plugs your ear, you keep your situational awareness, which is precisely why the feature list leans so hard into running, yoga and outdoor use.
The specs back that up. IP68 is a serious water-and-dust rating, and the copy is explicit that sweat and rain are not a concern. The hook-style fit uses liquid silicone on the contact surfaces, which the brand says reduces wearing pressure compared to the previous generation's hard plastic — relevant when you are wearing something for a two-hour ride. Weight is 2.72 ounces for the set, and the charging case is a compact ABS shell roughly the size of a small snack bar.
Battery is the headline. Up to 15 hours continuous, plus four extra full charges from the case for up to 60 hours total, with a 5-minute top-up giving an hour of playback and a full charge in about 1.5 hours. Bluetooth 6.0 with a fast-pairing chip means opening the case is basically the pairing step. There are two EQ modes — Music for bass-forward listening and Reading for voice content like audiobooks — which is a smart concession to the fact that bone conduction naturally favors mid-range speech over deep bass.
Who should buy it: runners, cyclists, gym-goers and anyone who refuses to be deaf to traffic or a training partner. Who should skip it: anyone who wants silence on a plane, deep sub-bass for electronic music, or a discreet bud that disappears in the ear. There is no noise cancellation here, and the 8-ohm impedance with 86 dB sensitivity tells you it is tuned for efficiency rather than audiophile isolation.
Side-by-Side: Which Should You Choose?
• Best for noise cancellation → Samsung Galaxy Buds 3. It is the only one of the two with Active Noise Cancellation.
• Best for running, yoga and sweaty workouts → DEMICEA Gen 2. IP68 waterproofing and an open-ear hook design are made for it.
• Best for calls and voice content → Samsung Galaxy Buds 3. Sealed in-ear fit plus clear-call features and voice control.
• Best for staying aware of your surroundings → DEMICEA Gen 2. Bone conduction leaves your ear canal open by design.
• Best for travel and commuting → Samsung Galaxy Buds 3. Noise cancellation is the whole point on a plane or train.
• Best for a secure, sealed fit → Samsung Galaxy Buds 3. Silicone in-ear tips with an earbud shape.
• Best for a lighter, more discreet object on your head → Samsung Galaxy Buds 3. At 1.84 ounces it is the lighter package; the DEMICEA set is 2.72 ounces with a hook-style frame.
If I had to pick one, I would buy the Samsung Galaxy Buds 3. In my opinion it is the better all-rounder for the way most people actually listen — commuting, calls, video, background music — because noise cancellation and a sealed fit solve the most common annoyance. I would only go the other way if movement is your priority. If you run, ride, or train outdoors and you want to hear the world while you listen, the DEMICEA Gen 2's IP68 rating and 60-hour battery make it the more sensible buy, and I would not hesitate to recommend it for that specific job. Check the current price on Amazon for both before you commit, since the gap between them is the one thing specs cannot tell you.
how to connect true wireless earbuds
Open the charging case and take the buds out — most true wireless models, including both of these, enter pairing mode automatically the first time. Then go to your phone's Bluetooth settings, find the model name in the list and tap it. The DEMICEA Gen 2 uses Bluetooth 6.0 with a fast-pairing chip, which the brand says makes the initial connection quicker than the previous generation.
how to pair true wireless earbuds
Pairing means introducing the buds to one device so they remember each other. Turn on Bluetooth on your phone or laptop, put the buds in pairing mode (usually by opening the case or holding the button), and select them from the available devices list. After that first pairing, both the Galaxy Buds 3 and the DEMICEA Gen 2 should reconnect on their own when you take them out.
how to use true wireless earbuds
Charge the case first, then take the buds out and put them on — in-ear tips for the Samsung Galaxy Buds 3, over-the-ear hooks for the DEMICEA Gen 2. Playback on the Buds 3 is handled by voice control for volume and tracks; the DEMICEA Gen 2 uses an EQ mode switch to flip between Music and Reading profiles. Neither one has a headphone jack, so everything runs over Bluetooth.
how to bluetooth true wireless earbuds
"Bluetooth-ing" them is really just pairing over Bluetooth, not a separate step. Make sure Bluetooth is enabled on your device, keep the buds within range — the DEMICEA Gen 2 lists a 10-meter range — and select the earbuds from your device's Bluetooth menu. If they do not appear, put them back in the case, close it, reopen it, and try again.
