If you want a more feature-rich open-ear pair with adjustable hooks, app-style EQ and light customization, choose Anker Soundcore V20i; if you need marathon battery life and a soft silicone ear-hook fit that stays put through long workouts and workdays, choose kurdene Open Ear Buds.
• Anker Soundcore V20i — biggest strength: Four adjustable hook positions plus 16mm drivers with BassUp, so you can tune the fit and get a fuller low end. It also adds customizable tune-synced lights.
• Anker Soundcore V20i — biggest trade-off: 8 hours of playtime per charge (1.5-hour charge time) and no charging case listed in the box contents beyond the cable and docs card.
• kurdene Open Ear Buds — biggest strength: 12 hours per charge with a charging case that adds up to 48 more, for a 60-hour total — the clear endurance pick.
• kurdene Open Ear Buds — biggest trade-off: No adjustable fit positions; the silicone ear hooks are a fixed shape, and the listed charge time is long at 12 hours.
• Pick Anker Soundcore V20i if you care about fit tuning, bass, calls and a bit of style.
• Pick kurdene Open Ear Buds if you want the longest battery life and a soft, stable hook for running and meetings.
The V20i is the more "engineered" of the two. The headline design idea is the four adjustable positions — you rotate the hook to find the spot that sits right on your ear, which matters a lot with open-ear headphones because fit is what keeps the sound aimed where it should be. Anker also pairs 16mm drivers with titanium-coated domes and BassUp, and on paper that's a bass-forward approach. Open-ear designs naturally leak low end, so a bigger driver tuned for bass is a sensible way to compensate.
Call quality gets real attention too: four microphones plus an AI algorithm for voice pickup. If you take meetings on the move or call people from a noisy street, that's the spec to care about. Add Bluetooth 5.4 with multipoint — so you can stay connected to a laptop and a phone at once — plus IP55 water resistance and touch controls, and you have a pair built for urban commuting, outdoor walks and all-day wear. The tune-synced lights are a nice touch if you like your gear to look like something.
Who should skip it? If you want to go a full week between charging, or you hate the idea of remembering to plug in a case, the 8-hour rating is the weak point. And with no charging case in the listed contents, you're relying on the buds themselves. In my opinion, the V20i is for the buyer who wants control — over fit, over bass, over the look — and doesn't mind charging more often.
The kurdene pair is built around one big idea: keep going. You get 12 hours on a single charge, and the included charging case adds up to 48 more, for a 60-hour total. That's the number that separates it from the V20i. If you're the type who throws buds in a bag and forgets about them until the next run, that case is doing the heavy lifting for you.
The fit story is different too. Instead of adjustable positions, kurdene uses soft silicone ear hooks that rest gently on top of your ears — pressure-free, snug, stable. There's no rotating or tuning; it's a fixed shape that either suits your ears or doesn't. For a lot of people that's fine, and silicone tends to feel kind on skin during sweaty sessions. The 16.1mm vibrating diaphragm drivers aim for powerful bass with crisp mids and clear treble, and the built-in mics handle voice isolation for calls. Bluetooth 5.4 with a listed 10-meter range covers the usual around-the-house and outdoor distances, and touch controls include separate multifunction and volume buttons on each bud, so you can adjust volume without reaching for your phone.
The trade-offs are real, though. A 12-hour charge time is slow — you'll want to charge overnight. The enclosure is silicone, which feels nice but isn't rated with an IP number here. And there's no multipoint listed, so juggling two devices at once isn't part of the pitch. In my opinion, kurdene is for the runner, the gym-goer and the long-shift worker who wants battery life first and a soft, simple hook second.
• Best for battery life → kurdene Open Ear Buds. 12 hours per charge plus a case for 60 total beats 8 hours with no case listed.
• Best for fit customization → Anker Soundcore V20i. Four adjustable positions let you rotate the hook until it sits right; kurdene's hooks are fixed.
• Best for bass-focused listening → Anker Soundcore V20i. 16mm drivers with titanium-coated domes and BassUp are explicitly tuned for low end.
• Best for calls in noisy places → Anker Soundcore V20i. Four mics plus an AI voice algorithm versus kurdene's built-in mics.
• Best for long runs and sweaty workouts → kurdene Open Ear Buds. Soft silicone hooks and a stable, pressure-free fit, backed by all-day battery.
• Best for switching between phone and laptop → Anker Soundcore V20i. Multipoint on Bluetooth 5.4 handles two devices at once; kurdene lists Bluetooth 5.4 without multipoint.
• Best for a bit of personality → Anker Soundcore V20i. Tune-synced customizable lights, plus IP55 water resistance.
• Best for charging convenience → kurdene Open Ear Buds. The included case gives you days of top-ups; the V20i's listed contents don't include a case.
I'd buy the Anker Soundcore V20i. The adjustable hooks, 16mm BassUp drivers, four-mic call setup, multipoint and IP55 rating cover more of what I actually want from open-ear headphones day to day, and 8 hours per charge is enough for a commute and a work session. If battery life is your single most important spec, though, the kurdene set's 60-hour total is hard to argue with. Weigh those two priorities honestly — everything else is close. Either way, check the current price on Amazon before you commit, since the two don't sit in the same bracket.
how to open ear headphones work
Open-ear headphones rest outside your ear canal instead of sealing it, so sound is delivered toward your ear while ambient noise still gets in. Both the V20i and the kurdene pair use this approach, which is why they're pitched for awareness during commutes and workouts.

Pair over Bluetooth 5.4, then use the touch controls on each bud for playback, calls and volume — both models support touch control. The kurdene pair has separate multifunction and volume buttons per bud, and the V20i supports multipoint so it can stay linked to two devices.
Is the kurdene Open Ear Buds worth it over the Anker Soundcore V20i?
It depends on what you value. kurdene wins on battery — 12 hours per charge plus a case for 60 total — while the V20i wins on fit adjustment, bass tuning, four-mic calls and multipoint. Check the current price on Amazon for both before deciding.
