If you want maximum battery life and a rock-solid, no-fuss workout headphone with physical ear hooks, choose Amazon Renewed Powerbeats3; if you need active noise cancellation, a waterproof dustproof build and a charging case that stretches total playtime to 48 hours, choose Anker Soundcore Sport X20.
• Amazon Renewed Powerbeats3 — biggest strength: Up to 12 hours of playback on a single charge, plus Fast Fuel (a 5-minute top-up gives you 1 hour), and flexible, secure-fit earhooks for stability.
• Amazon Renewed Powerbeats3 — biggest trade-off: No noise cancellation ("noise control: None"), Bluetooth range listed at 100 meters, and it's a renewed unit covered by a 90-day limited warranty.
• Anker Soundcore Sport X20 — biggest strength: Active noise cancellation with manual and adaptive modes, IP68 waterproof/sweatproof/dustproof build, and a charging case that pushes total playtime to 48 hours.
• Anker Soundcore Sport X20 — biggest trade-off: Earbud battery is 12 hours (same as the Powerbeats3 on its own), Bluetooth range is listed at 10 meters, and it relies on touch controls that some people find fiddly.
• Pick Powerbeats3 if you want long single-charge endurance, physical earhooks and don't care about noise cancelling.
• Pick Soundcore Sport X20 if you want noise cancellation, the toughest water/dust protection and a case that keeps you going for days.
The Powerbeats3 is the classic "hook over the ear and forget about it" design. The flexible, secure-fit earhooks are the headline here — they wrap around the ear rather than relying on a tip seal alone, which is exactly what you want when you're moving and don't want to keep pushing an earbud back in. The enclosure mixes rubber and silicone, and the package includes four sets of eartips so you can dial in the fit. Sound is described as dynamic, high-performance, with a 20 Hz–20,000 Hz range and 13 ohm impedance.
Battery is where this one shines. Up to 12 hours of playback on a single charge means you can knock out several workouts across a week before you even think about the cable. When you do run low, Fast Fuel gives you roughly an hour of playback from a 5-minute charge — genuinely useful if you're heading out the door and realize you forgot to plug in. It charges over Micro USB, and the box includes a case and cable.
Controls live on the RemoteTalk inline remote: take calls, control music, and activate Siri. It connects over Class 1 Bluetooth, and the spec sheet lists a 100-meter Bluetooth range and the ability to connect to an Apple Watch, iPad and Mac simultaneously (with the right iCloud and OS versions). There's no noise cancellation here — noise control is listed as "None" — so this is a headphone for people who want to hear the world around them or don't mind ambient gym noise.
Who should buy it: Runners, lifters and anyone who prioritizes long battery life and a physical earhook fit over noise cancelling. It's also a fit for Apple users who like Siri and multi-device switching.
Who should skip it: Anyone who wants active noise cancellation, a charging case, or a dust/water rating spelled out. And because it's a renewed unit with a 90-day limited warranty, buyers who want brand-new packaging and a longer warranty window should look elsewhere. The color is black.
The Sport X20 is the more feature-loaded of the two. Its fit system is adjustable: the ear hooks extend up to 4mm and rotate up to 30 degrees, so you can tune the position rather than accepting a fixed shape. Anker also points you to a Fit Test in the soundcore app to check you've got the ideal seal — a nice touch if you've struggled to get earbuds to stay put.
The big differentiator is noise cancelling. Manual and adaptive ANC turn a loud gym into a quiet one — clanging weights, background chatter, all pushed down. If you train in a busy commercial gym, that's a real quality-of-life upgrade the Powerbeats3 simply doesn't offer. Bass gets a boost too, via BassUp technology and 11mm dynamic drivers, with a 20 Hz–20,000 Hz range, 93 dB sensitivity and 10 ohm impedance.
Durability is the other selling point. The IP68 rating plus soundcore's SweatGuard technology and a cavity-sealed design protect the internals from water, sweat and dust. For anyone who sweats heavily or trains outdoors, that's meaningful protection.
Battery is split across two numbers: the earbuds run up to 12 hours, and the charging case adds up to 48 hours total, with a 580 mAh case capacity. Controls are touch-based with volume control. Bluetooth 5 is on board, with a listed range of 10 meters. It weighs 2.08 ounces, comes in green, and carries an 18-month warranty. There's no headphone jack, and the enclosure is ABS/PC with a plastic case.
Who should buy it: Gym-goers who want noise cancelling, heavy sweaters who need IP68 protection, and anyone who values a charging case and a longer warranty.
Who should skip it: People who dislike touch controls, want the maximum possible Bluetooth range, or prefer a physical inline remote over touch gestures.
• Best for battery life (single charge) → Amazon Renewed Powerbeats3. Up to 12 hours on the buds alone, plus Fast Fuel top-ups.
• Best total playtime with a case → Anker Soundcore Sport X20. Up to 48 hours when you include the charging case.
• Best for noisy gyms → Anker Soundcore Sport X20. Adaptive and manual ANC is the deciding feature here.
• Best for heavy sweat and outdoor training → Anker Soundcore Sport X20. IP68 waterproof, sweatproof and dustproof with SweatGuard.
• Best for secure, adjustable fit → Anker Soundcore Sport X20. Rotatable, extendable ear hooks (30 degrees, 4mm) plus an app Fit Test.
• Best for a simple physical fit and inline controls → Amazon Renewed Powerbeats3. Flexible earhooks and a RemoteTalk remote with Siri.
• Best for Apple multi-device users → Amazon Renewed Powerbeats3. Listed simultaneous connection to Apple Watch, iPad and Mac.

In my opinion, if you train in a busy gym and sweat hard, the Anker Soundcore Sport X20 is the one I'd buy — noise cancelling, IP68 protection, a 48-hour total battery with the case, and an 18-month warranty are a lot of practical value in one package. I'd only steer you to the Amazon Renewed Powerbeats3 if battery endurance on a single charge, physical earhooks and inline Siri controls matter more to you than ANC and a charging case. Both are legitimate picks — they just solve different problems. Check the current price on Amazon for whichever one fits your training.
Neither is universally better. The Sport X20 wins on noise cancelling, IP68 protection and total battery with its case; the Powerbeats3 wins on single-charge battery (up to 12 hours plus Fast Fuel) and its physical earhook fit with a RemoteTalk remote.
No. The spec sheet lists noise control as "None." If active noise cancellation is a must, the Sport X20 is the right choice — it offers both manual and adaptive ANC.
Yes. They carry an IP68 rating, described as waterproof, sweatproof and dustproof, with SweatGuard technology and a sealed cavity design protecting the internals. They're the better pick for heavy sweat and outdoor training.
The Powerbeats3 delivers up to 12 hours on a single charge with Fast Fuel (5 minutes for about 1 hour). The Sport X20 also runs up to 12 hours per charge, but its charging case extends total playtime to 48 hours.
