How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want safe, volume-limited headphones a young child can bend, twist and chew without breaking them, choose HamiltonBuhl Flex‑Phones Kids Foam; if you need a hard, waterproof case to protect a pair of kids' on-ear headphones you already own, choose Tourmate Hard Travel Case.
• HamiltonBuhl's biggest strength: it's built like a toy and engineered like a safety device — a single piece of flexible EVA foam, an 85 dB volume ceiling, and a chew-resistant braided cord.
• HamiltonBuhl's biggest trade-off: it's a wired kids' headphone only, so there's no wireless freedom and no protection when it's tossed in a backpack.
• Tourmate's biggest strength: a shockproof, waterproof EVA hard shell with a 360-degree zipper, mesh pocket and carry handle that keeps a pair of on-ear headphones safe in transit.
• Tourmate's biggest trade-off: it's a case only — no headphones inside — and it's shaped around specific models, not a universal fit.
• Buy HamiltonBuhl if you're equipping a young child (3+) for school, remote learning or tablet time and want one durable, safe pair.
• Buy Tourmate if your headphones already exist and what's missing is protection.
The Flex‑Phones are one of those rare products where the design story is the whole story. The frame is a single piece of soft, flexible, BPA‑free EVA foam. There are no hinges, no sliding joints, no plastic arms waiting to snap the first time a kid yanks them off their head. Bend it, twist it, sit on it — the material flexes back. For a classroom, a daycare or a household with more than one small child, that's the difference between headphones that survive a school year and headphones that come home in two pieces.
Then there's the audio side. These are capped at 85 dB, which is the commonly cited ceiling for protecting young, developing ears. The driver is dynamic with a 20 Hz – 20 kHz frequency range, 32 ohm impedance, and an on-ear fit with round pads covered in soft leatherette. A snap-on extension band is included so the fit tightens up for smaller heads. Recommended age is 3 and up, which lines up with preschool through elementary. The connection is a standard 3.5 mm stereo plug, so Chromebooks, tablets, laptops, PCs and classroom audio gear all work without adapters. The cable itself is a 4 ft braided, PVC-jacketed Dura‑Cord built to resist chewing and kinking — a genuinely thoughtful detail if you've ever watched a four-year-old treat a headphone cable like a snack.
Who should buy it: parents of young kids, teachers outfitting a classroom, anyone who needs a wired, volume-limited pair that can take abuse. Who should skip it: older kids and teens who want wireless convenience, richer sound or noise cancellation, and adults who care about looks more than indestructibility. There's also a 1-year warranty, which is a reasonable backstop on a product aimed at children.
The Tourmate case solves a completely different problem. You already have on-ear headphones — specifically Philips K4206 Kids Wireless, iClever HS19 Kids or RORSOU R10 on-ear models — and you need somewhere safe to put them. The shell is EVA, the same family of material as the Flex‑Phones frame, but here it's used for rigidity rather than flexibility. It's shockproof, waterproof and tear-resistant, which covers the three things that actually kill headphones in a backpack: drops, spills and being crushed under textbooks.
The practical details are where it earns its place. The zipper runs a full 360 degrees and is described as smooth and rigid, so it opens wide instead of fighting you. There's a built-in mesh pocket for accessories — a charging cable, a dongle, a small adapter — and a wide handle strap that makes it comfortable to carry by hand. External dimensions are listed at 7.4 by 3.5 inches, so it's a compact, pocketable-in-a-bag footprint rather than a bulky box. It's purple, solid-patterned, and rated for kids.
The important caveat: this is case only. The listing title says it plainly, and so does the spec sheet. No headphones, no cables, no tools. It's also sized for specific models, so if your headphones aren't one of the compatible ones, don't assume a fit.
Who should buy it: anyone who already owns one of the compatible kids' on-ear headphones and wants them to survive travel, school bags and storage. Who should skip it: anyone who doesn't yet own headphones, or whose model isn't listed as compatible.
• Best for young children (3+) → HamiltonBuhl Flex‑Phones Kids Foam. The 85 dB limit and foam build are aimed squarely at that age group.
• Best for protecting headphones you already own → Tourmate Hard Travel Case. Protection is the entire product.
• Best for classroom or multi-child environments → HamiltonBuhl. Bendable, chew-resistant and wired means fewer breakages and no pairing headaches.
• Best for travel and commuting with kids' gear → Tourmate. Shockproof, waterproof EVA shell plus a carry handle.
• Best for wireless freedom → neither. HamiltonBuhl is a wired 3.5 mm headphone; Tourmate is a case, not a device.
• Best for accessories organization → Tourmate. The built-in mesh pocket is the only storage feature in this comparison.
• Best for a single, complete purchase → HamiltonBuhl. It's a finished product; the Tourmate case assumes you've already bought headphones.
• Best if fit is uncertain → HamiltonBuhl. The snap-on extension band adjusts for smaller heads; the Tourmate case fits only its listed models.
In my opinion, if you're buying for a child, the HamiltonBuhl Flex‑Phones Kids Foam is the one to get. It's a complete, self-contained product with a real safety feature — the 85 dB cap — and a durability story that actually makes sense for how small kids treat their things. The Tourmate case is a genuinely good accessory, but it only makes sense as a second purchase, after you already own compatible on-ear headphones and want them to last. If that's your situation, buy the case. If you're starting from zero, start with the Flex‑Phones.
what are the best open ear headphones
"Open ear" and "on ear" get used loosely, and the two products here are on-ear designs — the Flex‑Phones sit on the ear with round leatherette pads. The Tourmate case is not a headphone at all; it's a protective shell for on-ear models. If open-ear or on-ear fit is your priority, judge it by the pad design and clamping band, which is where the Flex‑Phones' snap-on extension band matters.
are on ear headphones good
On-ear headphones are a solid choice for kids and casual listening: they're lighter and more compact than over-ear models, and they don't seal the ear canal the way in-ear designs do. The trade-off is less isolation — you'll hear more of the room. For a child in a classroom or at a tablet, that's often a feature rather than a flaw.
are open ear headphones good
Open and on-ear designs let in ambient sound, which is useful for safety and situational awareness but weaker for noisy environments like a bus or a plane. The Flex‑Phones are on-ear with a 20 Hz – 20 kHz range and 32 ohm impedance, so they're easy to drive from a Chromebook or tablet without extra amplification.
what are the best in-ear headphones
In-ear models aren't represented in this comparison — neither the Flex‑Phones nor the Tourmate case is an in-ear product. If in-ear fit is what you want, you're shopping a different category, and a hard case like the Tourmate won't be shaped for earbuds. For kids, volume limiting and durability usually matter more than the in-ear versus on-ear distinction.
