• EarFun K2 — biggest strength: a genuine over-ear design with memory foam earpads, a twist-and-bend headband, and a 3.5mm cable that keeps it working even with the battery flat.
• EarFun K2 — biggest trade-off: no noise cancelling or isolation, so it won't quiet a noisy room, and the 2.5-hour charge is slower than the HQ20's quick top-up.
• 1MORE HQ20 — biggest strength: 65 hours of playtime, a 5-minute charge that adds 2.5 hours, and dual-device Bluetooth so a tablet and a laptop can both stay connected.
• 1MORE HQ20 — biggest trade-off: it's an on-ear fit rather than over-ear, so smaller ears get less of that cushioned, enclosed feel the K2 offers.
• Pick EarFun K2 if you want the most comfortable over-ear fit for a younger child and you value a wired fallback for school laptops.
• Pick 1MORE HQ20 if you want the longest runtime, automatic hearing protection, and less charging friction for an older kid juggling two devices.
The K2 is the comfort-first option. EarFun builds it around 40mm dynamic drivers with a 20 Hz–20,000 Hz frequency range, so the sound is balanced stereo rather than bass-heavy or tinny — voices come through clearly, which matters for online tutoring and read-along apps. The earpads use memory foam and the material is soft and breathable, and the headband is designed to be twisted, turned and bent without breaking. That's the kind of thing you appreciate when a seven-year-old treats headphones like a toy.
Safety and battery are the other two pillars. Volume is capped at 85/94dB, which EarFun ties to the WHO recommended level for protecting young ears, and there are two power levels on the control side. Battery life runs up to 40 hours, with a 2.5-hour USB-C recharge. If your kid forgets to charge it — and they will — the included 3.5mm cable means it still works as a plain wired headphone. I like that a lot for a MacBook setup: plug straight into the headphone jack during a lesson and skip Bluetooth pairing entirely.
1MORE HQ20: Who It's For
The HQ20 is the endurance-and-safety play. Its headline feature is a three-level automatic volume limit at 75/85/95dB that reduces excessive sound on its own — you're not relying on a child to keep the volume sane, and you get a lower 75dB floor than the K2 offers. That's a meaningful difference for a younger or more impulsive listener.
Battery is where it pulls ahead: up to 65 hours on a charge, plus a 5-minute top-up that yields roughly 2.5 extra hours. For a kid who charges nothing, that's a real-world advantage. It also pairs with two devices at once over Bluetooth, so switching between a study tablet and entertainment is a tap rather than a re-pair — handy if the same headphones serve a school iPad and a family laptop.
The 40mm dynamic driver is here too, with the same 20 Hz–20,000 Hz range, and 1MORE describes the tuning as precise and clear. The fit is on-ear with rotating cups, an adjustable headband and leather-and-plastic construction, and it ships with a carrying case and a cable. Noise control is listed as sound isolation — passive sealing from snug cups, not active cancelling — so it reduces distractions in a classroom but won't erase a bus engine.
Who should buy it: parents who want automatic hearing protection, maximum runtime, and multi-device convenience for an older kid or teen. Who should skip it: a younger child who specifically wants a deep, cushioned over-ear cup, or anyone who wants the lowest possible volume ceiling — the HQ20 can go down to 75dB, but the K2's 85dB floor is simpler if you'd rather not think about modes.
Side-by-Side: Which Should You Choose?
• Best for quick top-ups → 1MORE HQ20 — a 5-minute charge adds about 2.5 hours; the K2 needs 2.5 hours for a full charge.
• Best for younger kids → EarFun K2 — over-ear memory foam cups, a bendable headband, and a simple 85/94dB cap.
• Best for automatic hearing protection → 1MORE HQ20 — three auto-adjusting levels starting at 75dB.
• Best fit for a MacBook with a headphone jack → EarFun K2 — the 3.5mm cable works with no pairing and no battery.
• Best for two-device households → 1MORE HQ20 — simultaneous Bluetooth connection to two devices.
• Best for quiet focus → 1MORE HQ20 — snug isolating cups versus the K2's open, uncancelled fit.
• Best for travel and storage → both — both fold, but the HQ20 also includes a carrying case.
If you're hunting for the best gaming headset for a MacBook, be realistic: neither of these is a gaming headset. They're kid-focused Bluetooth headphones with mics, low-latency Bluetooth, and 40mm drivers. The K2's wired cable makes it the more sensible pick for a laptop session, while the HQ20's dual connection suits swapping between a game on one device and a call on another. Neither is positioned as hi res open ear headphones for a MacBook, and neither is a neckband design — if that's specifically what you want, look elsewhere. As the best neckband headphones for a MacBook, these simply aren't it.
In my opinion, the 1MORE HQ20 is the better buy for most families in 2026. The longer battery, the automatic three-level protection, and dual-device switching solve the three things that actually annoy parents day to day. I'd pick the EarFun K2 instead if the child is young, wears headphones for long stretches, and you want the plusher over-ear fit — plus that 3.5mm cable, which makes it the smoother partner for a MacBook when Bluetooth isn't cooperating. Check the current price on Amazon for both before deciding, since value shifts over time.
FAQ
what is 40mm driver in headphones
A 40mm driver is the circular speaker unit inside the earcup, measured across at 40 millimeters. Both the EarFun K2 and 1MORE HQ20 use a 40mm dynamic driver, which is a common size for over-ear and on-ear headphones because it balances bass presence with clear vocals.
what are 40mm drivers in headphones
which driver is best for headphones
There's no single best size. Bigger drivers can push more bass; smaller ones suit in-ears. What matters more is tuning and fit. Here both models share a 40mm dynamic driver and a 20 Hz–20,000 Hz range, so the real differences are comfort, battery and volume limiting.
is 40mm driver good for headphones
Yes — 40mm is a solid, versatile size for on-ear and over-ear use, and it's plenty for music, audiobooks, lessons and calls. On both the K2 and HQ20 the driver is paired with a full 20 Hz–20,000 Hz frequency range, so you're getting the standard audible spectrum.
