How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want adjustable ear hooks that rotate and extend to lock into your ears plus deep BassUp tuning for the gym, choose Anker Soundcore Sport X20; if you need a lighter, app-tunable sport earbud with six mics for clearer calls and a flexible TwistLock fit, choose JBL Endurance Peak 4. Both are IP68, both are wireless, and neither one has a jack. So the real decision comes down to fit mechanics, noise control and call quality — not wires.
• Anker Soundcore Sport X20 — biggest strength: rotatable, extendable ear hooks (30 degrees of rotation, 4mm of extension) that let you dial in the hook position around your own ear shape, backed by 11mm drivers and BassUp.
• Anker Soundcore Sport X20 — biggest trade-off: the fit depends on you actually adjusting the hooks correctly, and the charging case takes 12 hours to top up.
• JBL Endurance Peak 4 — biggest strength: a 6-mic array (three per ear) with beamforming and a windproof design, which is a serious advantage for outdoor runs and calls.
• JBL Endurance Peak 4 — biggest trade-off: the charging cable is not included, and the earbud-only life drops to 8 hours once adaptive noise cancelling is on.
• Pick Anker Soundcore Sport X20 if you want the hook to move with you and you care most about bass and noise cancelling in a loud indoor gym.
• Pick JBL Endurance Peak 4 if you want app-based personalization, spatial sound, and clearer voice pickup during breezy outdoor sessions.
The Sport X20's whole pitch is fit. Instead of a fixed hook, Anker uses ear hooks that rotate up to 30 degrees and extend up to 4mm, so you can physically reposition the hook until it sits where your ear wants it. If you have ever fought with a sport bud that felt fine for ten minutes and then started working its way loose, that adjustability is the entire reason to look here. It's a mechanical answer to a fit problem, and it's the feature I'd weigh most heavily.
Buy the Sport X20 if you lift indoors, you want to tune the hook until it stays put, and you like a bass-forward sound. Skip it if you mainly take calls on windy runs — the spec sheet doesn't lean on mic count the way JBL's does — or if you'd rather not fiddle with hook angle at all. And if you were hoping for a wired option: there's no jack here, so your phone's cable isn't part of the picture.
JBL Endurance Peak 4: Who It's For
JBL's take is lighter and more software-driven. The Endurance Peak 4 uses OvalTubes with a TwistLock design plus a liquid silicone ear hook with memory wire, which is a different fit philosophy: instead of adjusting a hinge, you twist the bud into place and let the memory wire hook conform. It's a set-and-forget approach, and for a lot of people that's less fuss than dialing in an angle.
Where JBL clearly pulls ahead on paper is voice. Six mics — three per ear — with a beamforming algorithm and a windproof design target clear calls even on a breezy outdoor run. Adaptive noise cancelling pairs with Smart Ambient, so you can let the outside world back in without pulling a bud out, and the JBL Headphones app lets you set custom levels. The app also handles Personi-fi 3.0 personalization, activity presets for light, medium or intense workouts, and a Relax Mode with five ambient sounds. Sound is JBL Pure Bass with Spatial Sound from 10mm drivers.
Battery is 12 hours in the buds and 48 hours total with the case; with ANC on it's 8 hours plus 24. A 10-minute speed charge is quoted as four extra hours, and the case refills in about 2 hours. Bluetooth is 5.4. Buy it if you run outdoors, take calls mid-workout, and want an app to shape your sound. Skip it if you want maximum bass emphasis and adjustable hook geometry — and note the charging cable isn't in the box.
Side-by-Side: Which Should You Choose?
• Best fit adjustability → Anker Soundcore Sport X20. Rotating, extending hooks (30 degrees / 4mm) let you reposition the fit; JBL's TwistLock is a fixed twist-and-go design.
• Best for bass-first listeners → Anker Soundcore Sport X20. 11mm drivers with BassUp, against JBL's 10mm Pure Bass with Spatial Sound.
• Best for app customization → JBL Endurance Peak 4. Personi-fi 3.0, activity presets, Smart Ambient levels and Relax Mode all live in the JBL Headphones app.
• Best for quick top-ups → JBL Endurance Peak 4. A 10-minute charge is quoted at four extra hours, and the case refills in roughly 2 hours versus about 12 hours for the Anker case.
• Best for long ANC sessions → Anker Soundcore Sport X20. Its 12-hour bud figure doesn't drop when noise cancelling is on; JBL's falls to 8 hours with ANC on.
• Best for staying aware of traffic → JBL Endurance Peak 4. Smart Ambient is built for hearing your surroundings without removing a bud.
• Best if you want the cable in the box → Anker Soundcore Sport X20. JBL states the charging cable is not included.
In my opinion, the JBL Endurance Peak 4 is the better all-rounder for most people, and it's the one I'd buy. The six-mic setup, Smart Ambient, app personalization and fast 2-hour case charge cover more everyday situations — especially running outdoors and taking calls — than the Anker's narrower gym-focused strengths. That said, I'd steer you to the Anker Soundcore Sport X20 if bass and a tunable hook fit matter more to you than call clarity. Both are IP68 and both skip the headphone jack entirely, so a wired setup isn't on the table with either. Check the current price on Amazon before you commit, since that's the one variable a spec sheet can't settle for you.

Neither of these products is wired — both are Bluetooth earbuds with no headphone jack. If you're set on wired earbuds, the trick is usually a hook or fin that anchors against the ridge of your ear, plus the right tip size. With the Soundcore Sport X20, the equivalent solution is its rotatable, extendable ear hooks.

The classic fix is a silicone hook or ear-fin accessory that presses against the inside of your ear, plus swapping to a tip that actually seals. If you're comparing that experience to these two, note both use over-ear hook designs: Anker's hooks rotate and extend, while JBL's use memory wire inside a liquid silicone hook.

For a hook-style sport bud, seat the tip first, then swing the hook over the top of your ear and settle it behind the ridge. The Soundcore Sport X20 lets you rotate the hook up to 30 degrees and extend it 4mm to match your ear; the Endurance Peak 4 asks you to twist the bud in and let the memory wire hook conform.

Staying power comes down to fit mechanics and tip size. The Soundcore Sport X20's adjustable hooks let you reposition until the bud locks down, and the Endurance Peak 4 relies on its TwistLock design plus three eartip sizes. Both carry an IP68 rating, so sweat and rain won't be what dislodges them.
