If you want a lightweight, volume-capped pair of kids' headphones that can switch between wireless and wired listening on the fly, choose LEXiBOOK; if you need marathon battery life, a newer Bluetooth version, and a sturdier build for school and travel, choose Acer Kids.
• LEXiBOOK – biggest strength: True 2-in-1 flexibility — Bluetooth 5.0 wireless plus a detachable 3.5 mm jack cable, with a mic and push-button controls, all at a very light 5.12 oz.
• LEXiBOOK – biggest trade-off: The battery spec isn't published, the Bluetooth version is older, and the 3-month warranty is short compared to the Acer.
• Acer Kids – biggest strength: A claimed 60 hours of playtime, USB-C quick charging, Bluetooth 6.0, and a reinforced headband hinge built for rough handling.
• Acer Kids – biggest trade-off: It's heavier at 6.63 oz, comes only in pink, and its volume limiter offers a switchable 85/94 dB mode rather than a single fixed cap.
• Choose LEXiBOOK if you want the lightest possible pair for a younger child who mostly listens at home or on short trips and likes the Superman-style red-and-blue look.
• Choose Acer Kids if you want one pair that survives a school year — long battery, fast charging, and a grown-up feature set for online classes and travel.
The LEXiBOOK HPBT010BL is built around one clear idea: give a child a safe, simple, featherweight headphone that works however they want to use it. The 2-in-1 design is the headline. Bluetooth 5.0 lets it pair wirelessly with a phone or tablet at up to roughly 10 metres of range, and when the battery runs out — or when the device has no Bluetooth at all — you just plug in the detachable 3.5 mm jack cable and keep listening. That wired fallback matters more than it sounds. Tablets on a plane, school laptops, an older MP3 player in the car: a 3.5 mm jack covers all of them without an adapter.
On safety, the volume is capped at 85 dB. That's the widely used ceiling for children's listening, and it's applied here without gutting the sound — the frequency range runs the full 20 Hz to 20,000 Hz, so music still sounds like music rather than a muffled compromise. The built-in microphone and push-button controls mean a kid can answer a call, pause a video, or nudge the volume without reaching for a parent's phone. Passive noise cancellation is listed, which in practice means the closed earcups simply block some ambient noise — there's no active electronics doing the work.
Who should buy it? In my opinion, this is a strong pick for a younger child, roughly the early-primary age where the priorities are light weight, a hard volume cap, and a design they'll actually want to wear. The Superman red-and-blue colourway and the "Football" style name lean into that. At 5.12 oz it's the lighter of these two by a noticeable margin, which matters for small heads and long car rides. The foldable, adjustable frame collapses into a bag, and the open-ear earpiece shape keeps things airy rather than clamping down.
Acer Kids: Who It's For
The Acer Kids OHR668 is the more serious piece of hardware of the two. The battery claim is the standout: up to 60 hours of playback, with a 2.5-hour full charge over USB-C and a quick-charge mode that gives roughly 2 hours of listening from a 5-minute top-up. For a parent, that quick-charge detail is arguably more valuable than the 60-hour figure itself — it's the difference between a meltdown at the airport gate and a child happily watching a downloaded film. It also accepts a 3.5 mm cable for wired, lossless listening when you'd rather not stream.
Connectivity is Bluetooth 6.0 with a stated range of about 33 feet. That's a newer Bluetooth generation than the LEXiBOOK's 5.0, and in practical terms it means a more stable, lower-drama connection to a tablet or phone. The built-in mic handles voice calls and online classes, and the touch/button control setup lets a child manage playback directly. Note that noise control is listed as "none" — there's no passive cancellation claim here, so isolation comes purely from the over-ear cushions sitting around the ears.
Durability is where Acer has clearly aimed at real-world kids. The reinforced headband hinge is specifically described as able to withstand school bags, playgrounds and bumpy environments, and the whole thing folds compactly for storage. Comfort gets attention too: a lightweight build, ultra-soft memory foam cushions, and an adjustable ergonomic headband that fits a range of head sizes and leaves room to grow. Safety is covered by a switchable 85/94 dB limiter — 85 dB for everyday listening, 94 dB when a child genuinely needs more volume in a noisy environment like a plane cabin. Acer also states CPSIA certification and BPA-free materials.
Who should buy it? I'd point this at a school-age child who uses headphones daily — for lessons, video calls, gaming, and travel — and whose gear needs to survive being shoved into a backpack. The 1-year warranty is a meaningful reassurance next to the LEXiBOOK's 3 months. Who should skip it? A very young child for whom 6.63 oz is simply too much weight, anyone who needs a colour other than pink, and anyone who specifically wants passive noise cancellation. The 94 dB mode is also worth thinking about: it's a deliberate escape hatch, not a default, and parents should treat it that way.
• Best for battery life → Acer Kids. Up to 60 hours, plus 2 hours from a 5-minute USB-C charge, versus an unspecified runtime on the LEXiBOOK.
• Best for the lightest fit on a small head → LEXiBOOK. 5.12 oz against 6.63 oz is a real difference for younger wearers.
• Best for durability and rough handling → Acer Kids. The reinforced headband hinge and 1-year warranty are built for school life.
• Best for wired versatility out of the box → LEXiBOOK. A detachable 3.5 mm jack cable is included in the box, so wired listening works immediately; the Acer supports 3.5 mm cables but doesn't list one as included.
• Best for the newest wireless connection → Acer Kids. Bluetooth 6.0 with a 33-foot range beats Bluetooth 5.0 with a 10-metre range on paper.
• Best for a hard, fixed volume cap → LEXiBOOK. A single 85 dB limit leaves no room for a child to push the volume up.
• Best for flexible volume in noisy places → Acer Kids. The switchable 85/94 dB limiter gives you a choice without removing the protection.
• Best for comfort on long wear → Acer Kids. Memory foam cushions and a grow-with-me adjustable headband are designed for extended sessions.
If I were buying for my own household and had to pick one, I'd take the Acer Kids. The 60-hour battery, USB-C quick charging, Bluetooth 6.0, reinforced hinge and 1-year warranty add up to a pair that works as hard as a child does — and the switchable 85/94 dB limiter handles both quiet homework and a loud plane cabin. I'd only choose the LEXiBOOK instead if the child is young and small, the Superman styling is a selling point, and the headphones will mostly be used at home and in the car. Either way, check the current price on Amazon before you commit, since that changes far more often than the specs do.
For a very young child, I'd lean LEXiBOOK. At 5.12 oz it's the lighter pair, the 85 dB cap is fixed with no way to raise it, and the foldable frame is easy to pack. Acer's 6.63 oz weight and 94 dB option suit older kids better.
Acer states up to 60 hours of playtime, with a 2.5-hour full charge and a 5-minute quick charge giving about 2 hours. LEXiBOOK doesn't publish a battery-life figure in its specs, so treat the Acer as the safer bet for long trips.
Yes — both include a 3.5 mm jack. LEXiBOOK ships with a detachable jack cable, and its 2-in-1 design is built around switching between Bluetooth 5.0 and wired. Acer supports 3.5 mm cables for lossless audio, but lists only the manual as included.
Both limit volume to protect young ears. LEXiBOOK caps output at 85 dB with no override. Acer uses a switchable 85/94 dB limiter, plus CPSIA certification and BPA-free materials. In my opinion, the fixed cap is the more foolproof option for the youngest listeners.
