How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want the more grown-up, all-purpose over-ear pair for bigger kids, teens and adults with smaller heads, choose Sony MDR-ZX110; if you need a wired, volume-limited pair genuinely built for young children — small heads, small ears, school bags — choose JBL Junior 320. That's the short version, and it's the honest one: these two look similar on a shelf, but they're aimed at two different people.
• Sony MDR-ZX110 — biggest strength: an over-ear, closed-back design with a wide 12 Hz–22 kHz range and 30 mm neodymium dynamic drivers, so it sounds fuller and more detailed than a typical cheap headphone.
• Sony MDR-ZX110 — biggest trade-off: there's no volume cap and no ear protection of any kind; it's an adult-oriented product, so for a young child it's the wrong tool.
• JBL Junior 320 — biggest strength: JBL Safe Sound keeps output at or below 85 dB, and the whole design — 12 mm padded headband, round on-ear cups, 116.8 g — is scaled for children.
• JBL Junior 320 — biggest trade-off: it's a wired kids' headphone with a narrower 20 Hz–20 kHz range and modest 78 dB sensitivity, so it won't give an adult the punch or the freedom of a wireless can.
• For smaller heads generally: JBL Junior 320 is the one designed around small heads; Sony MDR-ZX110 is the one that simply fits a smaller adult or teen head without being built for kids.
• Who each pick is for: Sony MDR-ZX110 → teens and adults who want cheap, portable over-ear sound; JBL Junior 320 → parents buying for a child.
The MDR-ZX110 is a classic budget over-ear headphone, and its spec sheet reads like one. Sony lists a 12 Hz–22 kHz frequency range, 30 mm neodymium dynamic drivers and a highly sensitive diaphragm, which together suggest a sound you can push loud without an amplifier and still get clear, precise audio across the spectrum. The closed-back, enfolding design wraps around the ear and reflects acoustics back toward you — Sony's own framing is that this seals in music, keeps distractions out and maximizes the bass signature. For a headphone in this bracket, that's a sensible, well-understood recipe.
Comfort and portability are the other half of the story. You get a self-adjusting headband and soft cushioned earcups that cover the whole ear, plus a swivel-folding design so the cups lie flat for packing. The cable is a 1.2 m tangle-resistant y-type, which is the right length for a phone in a pocket or a laptop on a desk. At 181 g it's light enough to forget you're wearing it, and the 24 ohm impedance means almost anything can drive it.
Who should buy it? In my opinion, this is for a teenager or adult who wants a no-fuss, foldable over-ear headphone for commuting, study sessions or a desktop setup — and who happens to have a smaller-than-average head. The self-adjusting headband and full-ear cushions mean it doesn't perch awkwardly on a narrow head the way some rigid over-ears do. Who should skip it? Anyone shopping for a young child. There's no volume limiting here, the product is described as adult-oriented, and the 10 m Bluetooth figure listed in the connectivity data is worth treating with caution — this model is fundamentally a 3.5 mm wired headphone, so buy it for wired listening.
JBL Junior 320 is a different animal entirely, and it's refreshingly upfront about it. JBL Safe Sound means the headphones are designed never to exceed 85 dB — a deliberate ceiling to protect young ears. That single design decision tells you everything about the intended user: this is a child's headphone, not a scaled-down adult one.
The physical design follows the same logic. You get a 12 mm padded headband and round on-ear cups, which JBL says give better grip and less sound leakage — exactly what you want on a small head where a loose fit ruins both comfort and sound. The headband adjusts to follow a child's growth, which is a genuinely thoughtful touch for a product a kid might use for several school years. At 116.8 g it's noticeably lighter than the Sony, and the fold-flat design means it disappears into a backpack. The 32 mm drivers, 34 ohm impedance and 20 Hz–20 kHz range are perfectly reasonable for listening to lessons, videos and music.
Then there's the practical kid stuff: a built-in microphone so children can talk to teachers during remote lessons or chat with family, child-friendly push-button controls, a 3.5 mm jack, and a sticker set in the packaging so kids can personalize the cups. Passive noise cancellation — which here just means the closed cups physically block some outside sound — helps on a noisy bus or in a busy classroom. JBL also backs it with a one-year manufacturer warranty, and the listed age range is explicitly "Kid."
Who should buy it? Parents and guardians buying for a primary-school-age child, especially for school and travel. Who should skip it? Adults and older teens who want fuller sound, more bass, or wireless freedom. The Junior 320 is wired, volume-capped and tuned for safety over impact — and that's the point.
• Best for a young child → JBL Junior 320. The 85 dB Safe Sound limit and "Kid" age range make it the only responsible pick of the two for children.
• Best for smaller adult or teen heads → Sony MDR-ZX110. Over-ear cushions, a self-adjusting headband and 181 g of weight that sits comfortably without clamping.
• Best for ear safety → JBL Junior 320. No contest: Sony's spec sheet lists no volume ceiling at all.
• Best for sound quality potential → Sony MDR-ZX110. A wider 12 Hz–22 kHz range and 30 mm drivers versus JBL's 20 Hz–20 kHz and 32 mm drivers — the Sony reaches lower and higher.
• Best for the lightest fit → JBL Junior 320. At 116.8 g versus 181 g, the JBL is the one a kid won't complain about after an hour.
• Best for school and video calls → JBL Junior 320. The built-in mic and simple button controls are built for exactly that.
• Best for travel and packing → a tie, with a caveat. Both fold flat; the Sony folds flatter thanks to its swivel design, but the JBL is smaller and lighter to begin with.
• Best for durability with kids → JBL Junior 320. A one-year manufacturer warranty, silicone/fabric trim and kid-proof controls versus a plastic adult headphone.
If I were buying for myself or a teenager, I'd take the Sony MDR-ZX110 — the wider frequency range, over-ear cushions and fold-flat portability make it the more versatile headphone, and it handles a smaller head well. If I were buying for a child, I wouldn't hesitate: JBL Junior 320. The 85 dB limit, the 116.8 g weight, the growth-adjustable 12 mm headband and the built-in mic are all decisions made for small heads and small ears, and no amount of extra bass on the Sony justifies skipping that protection. Match the headphone to the head, and you'll be happy either way.
what are the best headphones for small heads
There's no single answer, because "small head" covers two very different buyers. For a child, the JBL Junior 320 is purpose-built — 12 mm padded headband, round on-ear cups for grip, 116.8 g, and an 85 dB volume cap. For a small-headed teen or adult, the Sony MDR-ZX110's self-adjusting headband and over-ear cushions fit comfortably. Pick by age first, then by features.
what headphones are good for small heads
Look for an adjustable or self-adjusting headband, light weight and cups that actually sit where they should. The JBL Junior 320 ticks all three for kids, with a headband that adjusts as they grow. The Sony MDR-ZX110 ticks them for older users, with a self-adjusting headband and full-ear cushions that don't perch. Both fold flat, so neither bulks up a bag.
which headphones are best for small heads
In my opinion, it depends entirely on who's wearing them. If it's a child, JBL Junior 320 wins — the 85 dB Safe Sound limit, kid-sized on-ear cups and 116.8 g build are designed around small heads. If it's a teenager or adult with a narrower head, Sony MDR-ZX110 is the better all-rounder thanks to its over-ear fit and wider 12 Hz–22 kHz range.
what are the best noise cancelling headphones for small heads
Neither of these offers active noise cancellation, so set expectations accordingly. The Sony MDR-ZX110 uses a closed-back, enfolding design that seals in sound and keeps distractions out, while the JBL Junior 320 lists passive noise cancellation from its closed cups. Both reduce outside noise somewhat; neither silences a plane engine. If true active cancellation matters, you'll need to look at a different category.
