How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want maximum battery life, a foldable over-ear design and wired backup, choose Anker Soundcore Space One; if you need pocket-size true wireless earbuds with water resistance and AI features tied to a Galaxy phone, choose Samsung Galaxy Buds 3.
• Anker Soundcore Space One — biggest strength: 60 hours of playback (40 with ANC on) plus a 5-minute charge that adds 8 hours, in a design that folds to half its size.
• Anker Soundcore Space One — biggest trade-off: It's an over-ear headphone, so it's bulkier than earbuds and its smartest features lean on the soundcore app rather than a phone ecosystem.
• Samsung Galaxy Buds 3 — biggest strength: A tiny in-ear design with IPX7 water resistance, Bluetooth 5.4 and Galaxy AI features like real-time interpretation.
• Samsung Galaxy Buds 3 — biggest trade-off: Battery life is measured in hours, not days, and several headline features only fully unlock on a Samsung Galaxy device.
• Buy the Anker Soundcore Space One if you want long-haul battery, over-ear comfort and a foldable travel shape.
• Buy the Samsung Galaxy Buds 3 if you want something you can wear to the gym and forget is in your pocket.
The Space One Pro is built around one idea: stay on your head, and stay on, for as long as possible. The 40 mm dynamic drivers cover a 20 Hz–40,000 Hz range and carry Hi-Res certification up to 40 kHz, and you can enable LDAC inside the soundcore app for higher-bitrate wireless streaming. That app is also where you shape the sound — bass, mids and treble are all adjustable, so you can push the low end for commuting or flatten it out for podcasts and acoustic tracks. The 4-stage adaptive ANC adjusts in real time, which is the kind of feature that matters most in airports, open offices and on city streets where noise changes minute to minute.
Comfort is the other half of the pitch. The headband flexes and self-adjusts rather than clamping down, and the protein leather plus slow-rebound foam is meant to sit gently through a full workday or a long flight. The earcups are oval and the whole thing weighs 9.6 ounces, so it's light for an over-ear. Then there's the travel angle: it folds to roughly half its size, which is the difference between a headphone that lives in a backpack pocket and one that lives on a desk. Battery is the headline — 60 hours with ANC off, 40 with it on, and a 5-minute top-up gives you 8 hours. Two hours gets you a full charge.
Samsung Galaxy Buds 3: Who It's For
The Galaxy Buds 3 Pro goes the opposite direction: everything shrinks. Each earbud weighs 5.4 grams, the case is plastic and pocketable, and control is by touch rather than buttons. Inside, a planar magnetic driver covers 20 Hz–20,000 Hz at 32 ohms, and Bluetooth 5.4 with SSC HiFi and UHQ codecs supports 24-bit/96 kHz audio — plus 360 Audio with Direct Multi-Channel for a surround-style effect. If you're watching a movie on a compatible Galaxy phone or tablet, that spatial processing is the feature that makes the earbuds feel like more than just small speakers.
The ANC here is the adaptive, AI-assisted kind: the earbuds listen to your environment and adjust, and Galaxy AI layers on things like real-time language interpretation and personalized sound profiles. Calls get Super Wideband microphones plus AI noise reduction that filters background noise and reconstructs parts of your voice that get lost. The IPX7 rating is the practical standout — that's water resistance rated for immersion, which makes these genuinely usable for workouts, rain and sweaty commutes in a way the Space One isn't designed for.
Two caveats worth knowing before you buy. First, many of the best features — 360 Audio, UHQ codec support, the AI functions — are exclusive to Samsung Galaxy Android devices, and the earbuds only deliver basic Bluetooth audio on iOS. Second, this listing is the international model and carries no warranty, which is a real consideration for a product with a battery inside. Who should buy it: Galaxy phone owners who want earbuds that integrate deeply with their device, plus anyone who needs water resistance and true portability. Who should skip it: iPhone users, people who want days of battery between charges, and anyone who'd rather not gamble on warranty coverage.
Side-by-Side: Which Should You Choose?
• Best for battery life → Anker Soundcore Space One. 60 hours (40 with ANC) versus 6.5 hours on the Buds 3, with a 5-minute charge adding 8 hours.
• Best for long flights and all-day desk work → Anker Soundcore Space One. Over-ear foam and a self-adjusting headband are built for hours of continuous wear.
• Best for pocketability → Samsung Galaxy Buds 3. A 5.4 g earbud in a plastic case beats a foldable headphone for "always with me."
• Best for wired fallback → Anker Soundcore Space One. It has a 3.5 mm jack and ships with an AUX cable; the Buds 3 have no jack at all.
• Best for Samsung Galaxy owners → Samsung Galaxy Buds 3. 360 Audio, UHQ codecs and Galaxy AI features only reach full potential on a Galaxy device.
• Best for iPhone or mixed-device users → Anker Soundcore Space One. Multipoint Bluetooth 5.3 and app-based EQ work the same regardless of phone brand.
• Best for sound tuning flexibility → Anker Soundcore Space One. The soundcore app gives you direct control over bass, mids and treble.
If I had to pick one for the average buyer, I'd take the Anker Soundcore Space One. In my opinion, the combination of 60-hour battery, adaptive ANC, multipoint, a wired option and a genuinely foldable frame makes it the more versatile purchase for most people — it covers commuting, flights, office days and movies without a charger in sight, and it doesn't care what phone you own. The Buds 3 Pro is the better choice only if you're already in Samsung's ecosystem or you specifically need IPX7 water resistance. Just check the current price on Amazon before deciding, and if warranty matters to you, note that the Buds 3 Pro listing here is the international model with no warranty.
Both use adaptive ANC that reacts to your surroundings, but they're different form factors. Over-ear cups physically cover your ears, which helps block more sound before the electronics even kick in. Earbuds rely more heavily on the ANC processing and a good seal from the eartips.
How long does the battery last on each?
Yes, they connect over Bluetooth, but many of the standout features — 360 Audio, UHQ audio codecs and the Galaxy AI functions — are limited to Samsung Galaxy Android devices. On iOS you get the basics, not the full feature set.
The Samsung Galaxy Buds 3 Pro, clearly. It's IPX7-rated for water resistance and weighs 5.4 g per bud, so it's built for sweat and movement. The Space One Pro is an over-ear headphone with no water-resistance rating, and it isn't the right shape for exercise.
