• Anker Soundcore V20i — biggest strength: four adjustable hook positions and 16mm titanium-coated drivers with BassUp, so it stays secure on adult ears and actually pushes bass.
• Anker Soundcore V20i — biggest trade-off: it has no volume limiter and no kid-focused safety ceiling, and it ships as a Renewed unit with a 90-day limited warranty.
• QearFun Kids Cat Open — biggest strength: a factory-set 85dB max volume plus 3.5g-per-ear clip-on comfort, which is exactly what a parent wants for young ears.
• QearFun Kids Cat Open — biggest trade-off: the sound is deliberately tuned away from heavy bass, and the whole appeal (cat case, lanyard, fidget twist) is aimed at kids, not adults.
• Pick the Anker Soundcore V20i if you're an adult who wants open-ear audio for commuting, running, calls and all-day wear.
• Pick the QearFun Kids Cat Open if you're buying for a child and hearing safety plus "don't lose them" matters more than sound quality.
The Soundcore V20i is the more "serious" product of the two, and the spec sheet tells you why. It uses an open-ear hook design with four adjustable positions, so you rotate the earpiece until it sits in the sweet spot on your ear. That's a small detail that matters a lot in practice: open-ear buds live or die on fit, and a hook you can reposition is far more forgiving than a fixed shape. It's built from ABS, polycarbonate and TPE, weighs 76.4g as a package, and comes in black.
On the audio side, Anker leans hard into the "open ear but still fun" pitch. There are 16mm drivers with titanium-coated domes, plus Anker's own BassUp processing, and a frequency range of 20Hz–20,000Hz. Big drivers in an open design are how you claw back some low end when you're not sealing the ear canal — so if you've tried open-ear buds before and found them thin, this is the one that's actually trying to fix that. The 11-ohm impedance suggests it's easy to drive from a phone.
The features I'd actually use: four mics with AI enhancement for calls (this is the real reason to buy open-ear for work — you stay present in the room and still sound clear on a call), Bluetooth 5.4 with multipoint so you can hop between laptop and phone, IP55 so sweat and light rain aren't a problem, and touch controls. Anker also adds tune-synced customizable lights, which is pure personality — some people will love it, some will turn it off. Battery is quoted at 8 hours per charge with a 1.5-hour charge time, and the box includes a cable and charging case.
QearFun Kids Cat Open: Who It's For
The QearFun Kids Cat Open is a completely different brief. It's a C-shaped clip-on that rests outside the ear — no insertion, no ear pressure — at just 3.5g per earbud, made from skin-friendly silicone. For a kid who rips headphones off after ten minutes because they hurt, that's the whole ballgame.
The headline feature is the 85dB factory-set volume limit. That's the number parents should care about most: it caps how loud the earbuds can ever go, which protects young ears in a way that no adult-focused earbud does. The tuning is deliberate too — QearFun says the sound is aimed at crisp vocals and balanced detail rather than heavy bass, which makes sense for stories, songs and online classes. A 12mm dynamic driver handles playback, and leakage is kept low so the kid next to them on the bus isn't hearing everything.
Then there's the case, and this is where QearFun gets clever. The charging case has rotatable, adjustable expression patterns — kids twist it to change the "mood" like a fidget toy. It sounds gimmicky until you remember that a fidget-y case is a case the kid actually keeps track of. Add the anti-lost lanyard and the whole design is built around one problem: children losing earbuds. The cat-ear styling and purple silicone finish are squarely aimed at kids, girls and teens.
Connectivity is Bluetooth 5.3 with a stated 10-meter range, USB-C quick charging, 6 hours of play per charge and 30+ hours total with the case. It's waterproof, the controls are touch/button, and it's covered by a 1-year manufacturer warranty. There's also a built-in mic, so it works for online classes and calls.
Side-by-Side: Which Should You Choose?
• Best for hearing safety → QearFun Kids Cat Open. The 85dB factory limit is the single most important difference between these two products.
• Best for sound quality and bass → Anker Soundcore V20i. 16mm titanium-coated drivers with BassUp versus a 12mm driver tuned for vocals.
• Best for calls → Anker Soundcore V20i. Four mics with AI enhancement beats a basic built-in mic for work calls.
• Best for connectivity and multitasking → Anker Soundcore V20i. Bluetooth 5.4 with multipoint lets you switch between two devices; the QearFun runs Bluetooth 5.3 with no multipoint listed.
• Best for a child who loses things → QearFun Kids Cat Open. The rotatable fidget case plus anti-lost lanyard is designed specifically for that.
• Best for all-day adult wear and workouts → Anker Soundcore V20i. Four adjustable hook positions, IP55, and 8 hours per charge.
• Best for the smallest ears → QearFun Kids Cat Open. 3.5g per earbud and a soft silicone clip-on beat a hook system sized for adults.
• Best for battery per charge → Anker Soundcore V20i at 8 hours, though QearFun quotes 30+ hours total with its case and lists a 150-hour average battery life figure.
If it's for me, I'd buy the Anker Soundcore V20i. In my opinion it's the better all-rounder for an adult: the adjustable hooks, the 16mm BassUp drivers, four-mic calls, Bluetooth 5.4 multipoint and IP55 add up to a device I'd actually wear every day. The 90-day Renewed warranty is the one thing I'd weigh carefully before committing.
But if I were buying for a child, I wouldn't hesitate on the QearFun Kids Cat Open. The 85dB cap, the 3.5g clip-on fit and the lanyard case solve the three problems parents actually have. Different buyers, different winners — and that's fine.
It's not designed as a kids' product. There's no volume limit, and the adjustable hooks are sized for adult ears. For a child, the QearFun's 85dB cap makes far more sense.
Not really, and by design. QearFun tunes them for clear vocals and balanced detail rather than heavy bass, which suits stories, lessons and kids' music better than thumping low end.
Per charge, the Anker Soundcore V20i is listed at 8 hours versus 6 hours for the QearFun. With the charging case, QearFun quotes 30+ hours total, so over a full week of short listening sessions the kid-focused pair can stretch further.
Technically yes — there's a built-in mic and Bluetooth 5.3. But the Anker Soundcore V20i's four mics with AI enhancement and multipoint connection are built for that job, so I'd pick the Anker for anything work-related.
