How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want kids' on-ear headphones with safe volume limiting and wireless freedom, choose Altec Lansing Kid Safe 2-in-1; if you need a protective hard carrying case for a pair of Sony ZX Series wired on-ear headphones you already own, choose YIHAOBOX Case Compatible. These two products share a category shelf but solve completely different problems — one is a listening device, the other is armor for a listening device.
• Altec Lansing Kid Safe 2-in-1 — biggest strength: a genuine audio product built around a child's needs, with an 85 dB maximum volume, Bluetooth 5 wireless plus a 3.5 mm wired option, and roughly 10 hours of battery life.
• Altec Lansing Kid Safe 2-in-1 — biggest trade-off: it's a kids' headphone first, so the sound signature and build are aimed at younger listeners, not adults chasing critical listening.
• YIHAOBOX Case Compatible — biggest strength: a hard EVA shell with a shockproof layer and fluffy inner lining that shields Sony ZX Series on-ear headphones from dust, scratches, scuffs, crush and moisture.
• YIHAOBOX Case Compatible — biggest trade-off: it is only a case. There is no audio hardware inside it, and it is shaped around specific Sony MDR-ZX110 / MDRZX110AP / MDRZX110NC / MDR-ZX310AP models.
• Who each pick is for: Altec Lansing for a parent buying headphones for a child; YIHAOBOX for someone who already owns a compatible Sony ZX Series pair and wants to keep it intact.
The Altec Lansing Kid Safe 2-in-1 is what most people picture when they hear "kids' headphones." It's an on-ear design with round earcups in Knight Blue, built from leather and plastic, and it pairs over Bluetooth 5 with a stated range of about 30 feet. There's also a 3.5 mm jack, which matters more than it sounds: a wired connection means unlimited listening time when the battery runs out, while Bluetooth gives you roughly 10 hours per charge.
Comfort is clearly part of the design brief. Soft ear cushions plus an adjustable headband mean the fit grows with your child, and the 0.27 kg weight is light enough that it shouldn't feel heavy over a long session. It also folds, which makes it easy to toss in a bag, and the box includes a carabiner clip and a carry bag — small touches that make it feel like a complete travel kit rather than just a headphone. In my opinion, this is the pick for parents of younger kids who want wireless convenience, a hard volume limit, and a wired fallback for when the battery dies. Skip it if you're buying for an adult, if you want active noise cancellation rather than passive, or if you need a case to protect a different pair of headphones — that's not what this is.
YIHAOBOX Case Compatible: Who It's For
The YIHAOBOX Case Compatible is a different animal entirely, and the name is the honest part: it's a case compatible with specific Sony headphones, not a headphone. The compatible list is Sony MDR-ZX110, MDRZX110AP, MDRZX110NC and MDR-ZX310AP from the ZX Series — the wired on-ear models. If you own one of those, this is a purpose-built home for it.
The construction is the whole story. A hard EVA shell gives the case its shape and resists crush, which is the failure mode that kills headphones in a backpack. Inside, there's an anti-static shockproof layer plus a fluffy fabric lining that absorbs impacts from accidental bumps. The description also lists semi-waterproofing, so splashes and moisture aren't an immediate threat. Dust, scratches and scuffs are all covered, which matters because the folding joints and cable on a wired on-ear pair are exactly the parts that degrade first.
It's light — 0.15 kg — and compact enough to drop into a bag, backpack or luggage without eating much space. Form factor is listed simply as a bag, and it ships with a one-year warranty. Who should buy it: anyone who already owns a compatible Sony ZX Series headphone and wants it to survive commuting, school bags and air travel. Who should skip it: anyone expecting audio, anyone whose headphones aren't on the compatibility list, and anyone shopping for a child's first headphone — this case is an accessory, not a gift that makes sound.
• Best for a child's hearing safety → Altec Lansing Kid Safe 2-in-1, thanks to the 85 dB volume limit.
• Best for wireless listening → Altec Lansing Kid Safe 2-in-1, with Bluetooth 5 and roughly 30 feet of range.
• Best for uninterrupted listening → Altec Lansing Kid Safe 2-in-1, since the 3.5 mm jack removes the 10-hour battery ceiling.
• Best for protecting a Sony ZX Series pair → YIHAOBOX Case Compatible, which is shaped specifically for MDR-ZX110, MDRZX110AP, MDRZX110NC and MDR-ZX310AP.
• Best for travel abuse → YIHAOBOX Case Compatible, with its hard EVA shell, shockproof layer and fluffy inner lining.
• Best for lighter carry → YIHAOBOX Case Compatible at 0.15 kg versus 0.27 kg for the headphones.
• Best all-in-one gift → Altec Lansing Kid Safe 2-in-1, which arrives with a carabiner clip and carry bag already included.
• Best if you need both → buy them separately; they're complementary, not competing, since the YIHAOBOX case isn't sized for the Altec Lansing headphone.
If I were buying for a child, I'd take the Altec Lansing Kid Safe 2-in-1 without hesitating. The 85 dB cap, Bluetooth 5, the wired backup and the foldable, adjustable build cover everything a parent needs in one purchase. I'd only reach for the YIHAOBOX Case Compatible if I already owned a compatible Sony ZX Series wired pair and wanted to stop replacing it every year. They solve different problems, and the right answer depends entirely on whether you need sound or protection. Check the current price on Amazon before deciding, since both are inexpensive enough that buying the pair together is a reasonable move.
what are the best open ear headphones
Worth clarifying first: neither product here is an open-ear design. The Altec Lansing Kid Safe 2-in-1 is an on-ear headphone with round earcups, and the YIHAOBOX Case Compatible is a carrying case, not a headphone at all. If open-ear is a hard requirement, neither matches — but if you actually want on-ear headphones for a child, the Altec Lansing fits.
are on ear headphones good
On-ear headphones like the Altec Lansing Kid Safe 2-in-1 rest against the ear rather than around it, and this pair uses soft cushions plus an adjustable headband for a light fit. They're a practical choice for kids because they're lighter and more compact than over-ear models, and this one adds passive noise cancellation plus a foldable frame for travel.
are open ear headphones good
That depends on your goal, and it's a separate category from both products here. The Altec Lansing is on-ear with passive noise cancellation, and the YIHAOBOX case is designed for Sony ZX Series wired on-ear headphones. If blocking outside noise matters, an on-ear closed design generally does more for you than an open-ear one.
are on ear headphones comfortable
Comfort comes down to padding and fit, and the Altec Lansing Kid Safe 2-in-1 addresses both: soft ear cushions, an adjustable headband, and a 0.27 kg weight that keeps pressure low over long sessions. For a wired pair, the YIHAOBOX case protects the earcups and folding joints between uses, which helps them stay comfortable and intact over time.
