How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a simple, corded, kid-tough pair of on-ear headphones that never needs charging and folds down small, choose noot products K33; if you need wireless freedom, a built-in mic for calls, and battery life measured in days rather than hours, choose Sony WH-CH520.
• noot products K33 — biggest strength: A wired 3.5mm design with a tangle-resistant nylon cord, foldable build and a 2-year warranty. Nothing to charge, nothing to pair, nothing to lose.
• noot products K33 — biggest trade-off: It's a plug-in headset. No Bluetooth, no microphone for calls, and the on-ear fit and sound isolation are basic rather than refined.
• Sony WH-CH520 — biggest strength: Up to 50 hours of battery life, quick charging (a few minutes of charge gives you up to 90 minutes of playback), Bluetooth 5.2, multipoint pairing and a built-in mic for hands-free calls.
• Sony WH-CH520 — biggest trade-off: It's wireless only — no 3.5mm jack at all. If the battery is flat or you want to plug into a school tablet or an airplane seat screen, you can't.
• Who the K33 is for: Younger kids and tweens who need a durable, no-fuss pair for school, iPad time, Kindle and travel.
• Who the WH-CH520 is for: Teens and older students who want a modern wireless pair with long battery life, call handling and app-based sound tweaking.
The K33 is built around one idea: keep it simple and keep it working. The connection is a plain 3.5mm jack, so it works with virtually any audio device that has that port — phones, tablets, computers and travel entertainment systems. There's no pairing, no app, no firmware, no charging cable to remember. You plug it in and it plays. For a parent handing headphones to a nine-year-old, that alone removes about half the daily friction.
Physically, it's designed for smaller heads. The padded cushions and plush earcups are described as fitting children's ears comfortably, and the lightweight on-ear build is meant for long sessions — music, movies, games and schoolwork. The cord is a 5ft nylon-wrapped cable chosen specifically to resist tangling, which matters more than it sounds when the headphones live at the bottom of a backpack. The whole thing folds, so it packs flat for a plane ride or a car trip. A 2-year warranty backs it up. The drivers are dynamic, 32 ohm impedance, 20 Hz to 20,000 Hz — a standard full-range spec. Volume control is listed as touch-based.
Who should buy it: parents buying for younger children, anyone who wants a spare pair that lives in a bag, and households where "the headphones died" is a recurring argument. Who should skip it: teens who want to walk around untethered, take calls, or use headphones with a phone that has no headphone jack. Also skip it if you need active noise cancelling — the K33 offers sound isolation only, which is a passive, physical kind of quieting, not electronic.
The WH-CH520 is the opposite philosophy: convenience first, wires never. It's Bluetooth 5.2 with a 10-metre range, and it pairs with two devices at once thanks to multipoint — so a teen can be watching something on a laptop and take a call on their phone without re-pairing anything. There's a built-in microphone for hands-free calls, which is the single biggest practical difference for a teenager who uses headphones for group chats, voice notes and online classes as much as for music.
Battery is the headline. Sony rates it at up to 50 hours of average life, with a 3-hour charge time, and quick charging that yields up to 90 minutes of playback from about 3 minutes on the cable. In real terms, that's a pair you charge on Sunday and forget about for the rest of the week. It charges over USB-C, and a short USB-A-to-USB-C cable is included.
Comfort is clearly a design priority: lightweight, on-ear, soft earpads, an added head cushion and swivel earcups so they slide on and off easily and pack flatter. The headband is adjustable. Sound is a dynamic driver, 32 ohm impedance, 20 Hz–20,000 Hz, 98 dB sensitivity — and it's customizable through the Sony Headphones Connect app, which offers EQ presets you can match to genres or build yourself. DSEE is included to lift compressed streaming files, and there's voice assistant support plus a find-my-headphones feature through Google's Find My Device. Sony lists the age range as adult, kid and teen, and it's available in six colours. Noise control is listed as none — no active noise cancelling here, so don't buy it expecting to silence a bus.
Who should buy it: teens and older students who want a wireless daily driver with serious battery life, call capability and a bit of sound personalisation. Who should skip it: anyone who needs a wired connection for a school device, a gaming controller, an in-flight entertainment screen or a laptop with a headphone jack and no Bluetooth — the WH-CH520 has no jack at all.
Side-by-Side: Which Should You Choose?
• Best for younger kids → noot products K33. The wired design, child-oriented fit and 2-year warranty suit rough handling and small heads.
• Best for battery life → Sony WH-CH520. Up to 50 hours, with quick charging as a safety net.
• Best for never thinking about charging → noot products K33. It draws power from whatever it's plugged into. There is no battery to run down.
• Best for calls and online classes → Sony WH-CH520. The built-in microphone makes hands-free calling possible; the K33 has no mic.
• Best for school tablets, Kindles and seat-back screens → noot products K33. Anything with a 3.5mm port works instantly.
• Best for packing and travel → both, for different reasons. The K33 folds; the WH-CH520 uses swivel earcups for a flatter, more compact shape.
• Best for sound customisation → Sony WH-CH520. App-based EQ and DSEE give you control the K33 simply doesn't offer.
• Best for durability against tangles and drops → noot products K33. The nylon-wrapped 5ft cord is designed not to tangle, and there are no electronics to fail in the cable-free sense.
If I were buying for a teenager, I'd buy the Sony WH-CH520. In my opinion, the wireless design, up-to-50-hour battery, multipoint pairing and built-in mic line up with how a teen actually uses headphones all day — music, calls, streaming, switching between laptop and phone. The lack of a headphone jack is the real cost, and it's worth checking whether their school devices still use one. For a younger child, or as a rugged backup pair that never needs charging, I'd take the noot products K33 instead. Two different jobs, two different answers — and both are worth checking the current price on Amazon before you commit.
what are good headphones for teens
Good teen headphones usually need three things: a comfortable on-ear or over-ear fit, enough battery or a simple wired connection to last a school day, and a mic if they take calls. The Sony WH-CH520 covers all three with Bluetooth 5.2, multipoint, a built-in microphone and up to 50 hours of battery. The noot products K33 covers the comfort and simplicity side with a wired 3.5mm jack and a foldable, padded on-ear design — but no mic.
what are popular headphones for teens
Popularity with teens tends to follow wireless convenience and looks. The WH-CH520 is wireless, comes in six colours, supports voice assistants and lets you tweak the sound in an app — all features that fit teen habits. The K33 leans the other way: it's a practical, kid-focused wired headset in Electric Blue, better suited to younger children than to style-conscious teenagers.
what are the best headphones for teens
There's no single best — it depends on whether the teen needs wireless or wired. If they want to move around, take calls and charge rarely, the Sony WH-CH520 is the stronger pick on specs: 50-hour battery, quick charging, multipoint and app EQ. If they mainly plug into a tablet, Kindle or laptop and you want zero charging hassle, the noot products K33 is the more practical choice.
what headphones are cool for teens
"Cool" is subjective, but the features teens tend to care about are wireless freedom, colour options and call quality. The WH-CH520 delivers on all three, with six colour choices, Bluetooth 5.2 and a built-in mic. The K33 is more of a functional school-and-travel pair — its selling points are the tangle-free nylon cord, foldable frame and 2-year warranty rather than style.
