If you want a complete, ready-to-use open-ear pair for running, workouts and all-day wear, choose Alpsnd Joy Open-Ear Headphones; if you need to replace a single lost or damaged right earbud for Samsung Galaxy Buds 3 Pro, choose korllo Single Right Replacement. These two products barely overlap. One is a full new headphone set built around an open-ear sports fit. The other is one pre-owned right-side earbud meant to revive a pair you already own.
• Alpsnd Joy Open-Ear Headphones — biggest strength: a complete open-ear system with around-ear earhooks, Bluetooth 5.4, four-mic ENC calls, app EQ and up to 40 hours of total battery with the case.
• Alpsnd Joy Open-Ear Headphones — biggest trade-off: IPX4 only covers sweat and light rain, and the open-ear design means you give up the noise isolation and deep bass sealing of an in-ear bud.
• korllo Single Right Replacement — biggest strength: a tested, fully functional right earbud that matches the original Galaxy Buds 3 Pro size and protocols, keeping ANC, 360° spatial audio and ambient mode intact.
• korllo Single Right Replacement — biggest trade-off: it is a pre-owned single earbud, right ear only, and it fits the Galaxy Buds 3 Pro AI version alone — not the standard Galaxy Buds 3 and not the left side.
• Buy Alpsnd Joy if you want a fresh, self-contained pair for sport, commuting and calls.
• Buy korllo if you already own Galaxy Buds 3 Pro and only the right bud is missing or broken.
The Alpsnd Joy is built around one idea: keep your ear canal open. The earhooks wrap around the ear rather than plugging into it, so there's no in-ear pressure and you stay aware of traffic, coworkers and surroundings. That's the whole point of an open-ear design, and it's why this set suits walking, running, gym sessions and long office days better than a sealed bud would.
The spec list is genuinely complete for the category. Bluetooth 5.4 with a 10-meter range handles pairing across iPhone, Android, tablets and laptops. Four microphones with AI noise reduction and environmental noise cancellation aim at clear calls and video meetings, which matters if you take a lot of them on the move. The 14.2 mm dynamic drivers are paired with an app that lets you tune the EQ, remap the touch controls, check earbud battery status and switch on a low-latency Game Mode rated at 45 ms. Battery is quoted at up to 10 hours per charge and 40 hours total with the case, and the case itself carries a 450 mAh cell with a 1.5-hour charge time.
Who should buy it: runners, gym-goers, commuters and office workers who want awareness plus a secure hook fit, and anyone who likes fiddling with an EQ app. Who should skip it: swimmers and shower users — IPX4 is sweat and splash resistance only, not immersion — and anyone chasing maximum isolation or the deepest possible bass, which an open-ear hook simply won't deliver the way a sealed in-ear will.
This is a repair part, not a new pair of headphones. The korllo Single Right Replacement is a pre-owned but fully functional right earbud made specifically for the Samsung Galaxy Buds 3 Pro AI version (SM-R630). It matches the original size and interface protocols, connects to the charging case, auto-syncs device info, and pairs with your existing left earbud to restore normal two-ear use.
The compatibility line is the critical part: it works with Galaxy Buds 3 Pro only, and not with the standard Galaxy Buds 3. It's also right-ear only. Inside, it carries the same high-definition speaker unit and AI chip as the original, so it still supports 360° spatial audio, active noise cancellation and ambient sound mode, with the bass, mids, highs and call noise reduction you'd expect. A one-year limited warranty covers manufacturing defects and functional issues under normal use — not physical damage, misuse or water exposure.
Side-by-Side: Which Should You Choose?
• Best for a complete new setup → Alpsnd Joy Open-Ear Headphones. It ships with the charging case, both earbuds, a USB cable and a manual.
• Best for fixing a lost right bud → korllo Single Right Replacement. It's the only one of the two that restores an existing Galaxy Buds 3 Pro pair.
• Best for running and gym work → Alpsnd Joy Open-Ear Headphones. Flexible earhooks plus IPX4 sweat resistance are made for movement.
• Best for noise cancellation → korllo Single Right Replacement. It carries over ANC and ambient mode from the original Galaxy Buds 3 Pro.
• Best for staying aware of your surroundings → Alpsnd Joy Open-Ear Headphones. The open-ear hook design never seals the canal.
• Best for battery life → Alpsnd Joy Open-Ear Headphones. Up to 10 hours per charge, 40 hours with the case.
• Best for call clarity → Alpsnd Joy Open-Ear Headphones. Four mics with AI noise reduction and ENC.
• Best for tuning your sound → Alpsnd Joy Open-Ear Headphones. The app EQ and control remapping are built in.
• Best if you own Galaxy Buds 3 Pro → korllo Single Right Replacement. It's the compatible, protocol-matched part.
If I had to pick one, I'd buy the Alpsnd Joy Open-Ear Headphones. In my opinion it's the better buy for most people because it's a complete, self-contained product: both earbuds, a case, an app, a full battery system and a fit designed for sport. The korllo replacement is excellent at exactly one job — reviving a Galaxy Buds 3 Pro set with a dead right bud — and it does that job well, but it's useless to anyone who doesn't already own those specific Samsung earbuds. Buy korllo only if that's precisely your situation.
FAQ
No. The listing states it's compatible with the Galaxy Buds 3 Pro AI version and explicitly not with the standard Galaxy Buds 3. It's also right-ear only, so it won't help if the left bud is the one you lost.
No. IPX4 means sweat and light-rain resistance, not water immersion. Swimming, showering and full submersion are outside its design.
