If you want a simple, lightweight on-ear pair for a child who mostly listens at home or in the car, choose JBL T450BT; if you need a modern, foldable headset with a much longer battery, USB-C charging and a microphone for calls, choose JBL Tune 510BT. That is the short answer for anyone shopping for children, and the rest of this comparison explains why the two JBL models feel like they come from different eras.
• JBL T450BT – biggest strength: very light on-ear design (0.14 kg, roughly 140 g), simple Bluetooth wireless playback with an inline remote and mic, and a 3.5 mm jack so it can still be used wired when the battery runs out.
• JBL T450BT – biggest trade-off: older Bluetooth 4, around 11 hours of playback, a 2-hour charge, no noise control and a short 90-day warranty description. It is a basic headphone, not a feature-rich one.
• JBL Tune 510BT – biggest strength: up to 40 hours of playback, a 5-minute speed charge that adds about 2 hours of music, USB-C charging, Bluetooth 5, a built-in microphone on the ear cup and a foldable, adjustable design.
• JBL Tune 510BT – biggest trade-off: it is a little heavier (160 g), relies on USB-C rather than a 3.5 mm jack, and its noise control is listed as none, so it will not block out background sound.
• For a young child who just needs a spare pair for home use → JBL T450BT.
• For a child or teen who takes headphones to school, on trips or to friends' houses → JBL Tune 510BT.
The JBL T450BT is the older, plainer design of the two. It is an on-ear wireless headphone with a dynamic driver, 16-ohm impedance and a frequency range listed as 20 Hz – 20 kHz, with the bullet spec quoting 80 – 18,000 Hz and 16 ohms. In plain terms, that is a standard listening range for everyday music, videos and games — nothing exotic, but nothing unusual for a budget on-ear pair either.
What stands out for family use is how little there is to break or configure. The ear cups are on-ear with a faux-leather enclosure, and the weight is listed at just 0.14 kg, which is genuinely light for a child's head. There is a built-in remote and microphone, so a child can pause, skip and take a call without touching a phone. Because it also has a 3.5 mm jack, it can be plugged into a tablet, a school laptop or a handheld console when Bluetooth is not allowed or the battery is empty. Battery life is around 11 hours with a 2-hour charge — enough for a couple of days of light use, not enough for a week-long trip without a cable.

I would point a parent toward the T450BT if they want a first pair for a younger child: light, wired-or-wireless, and simple enough that there is nothing to fiddle with. I would steer them away from it if the child needs long battery life, USB-C charging, a reliable microphone for online classes, or a newer Bluetooth version. The Bluetooth 4 spec is dated, the warranty description is short at 90 days, and the frequency response figures in the sheet are inconsistent between fields, which is a sign of how old this listing is.
The JBL Tune 510BT is the newer, more capable option and the one I would generally recommend for older children and teenagers. It uses Bluetooth 5, which typically means a more stable connection and better power efficiency than Bluetooth 4, and it supports switching between two paired devices so a child can move from a video on a tablet to a call on a phone without re-pairing.
Battery life is the headline number: up to 40 hours of playback with a 2-hour charge over USB-C, plus a speed charge that gives roughly 2 extra hours from a 5-minute top-up. For a child who forgets to charge things, that buffer matters far more than any spec on paper. The 32 mm dynamic driver, 32-ohm impedance and 96 dB sensitivity describe an easy-to-drive headphone that gets loud enough from a phone without an amp. JBL's own description frames it around "Pure Bass" sound, which is the tuning the brand is known for — a warm low end rather than a flat, studio-style balance.
For children specifically, several details line up well: the headband is adjustable to fit a range of head sizes, the ear cushions are soft with a padded headband, and the whole thing folds up for a backpack. The microphone sits on the ear cup with buttons for calls, and there is a multi-function button that triggers Siri or Google Assistant. Noise control is listed as none, so it does not actively cancel sound, and the enclosure is foam and plastic — light, but not built like a rugged kids' model.
I would buy the 510BT for a child or teen who uses headphones daily, takes them out of the house, and needs calls and long battery life. I would skip it for a very young child who might yank a USB-C port or lose a folding headphone, and for anyone who needs a wired fallback, since this model has USB connectivity rather than a 3.5 mm jack.
Side-by-Side: Which Should You Choose?
• Best battery life → JBL Tune 510BT. Up to 40 hours versus roughly 11 hours on the T450BT. For children, that is the difference between charging twice a week and charging every other day.
• Best for wired backup → JBL T450BT. The 3.5 mm jack means it works on a plane, a school laptop or a dead battery. The 510BT is wireless-only via USB charging.
• Best for calls and voice assistants → JBL Tune 510BT. Microphone on the ear cup, on-ear controls and a button for Siri or Hey Google.
• Best for lighter weight → JBL T450BT. Listed at 0.14 kg versus 160 g. The gap is small but noticeable on a small head over a long session.
• Best for travel and storage → JBL Tune 510BT. The foldable design and adjustable headband make it easier to pack and to fit growing children.
• Best for pure simplicity → JBL T450BT. Fewer features, older Bluetooth, nothing to configure — which some parents actively prefer.
• Best overall for children → JBL Tune 510BT, in my opinion, because the battery, USB-C charging, mic and foldable build all solve real problems that a child will hit within the first month.
If I were buying one of these two for a child today, I would buy the JBL Tune 510BT. The 40-hour battery, the 5-minute speed charge, Bluetooth 5, the ear-cup microphone and the foldable, adjustable frame are all things a child actually benefits from day to day — and they are the reasons it works as a hi-res-capable wireless headset for children rather than a spare pair that lives in a drawer. The T450BT still makes sense as a light, cheap-feeling-but-simple first headphone or a wired backup, and its 3.5 mm jack is a genuine advantage. But for the long haul, I would spend a bit more on the 510BT and check the current price on Amazon before deciding.
On paper, yes for most buyers. It has up to 40 hours of battery versus about 11, Bluetooth 5 versus Bluetooth 4, USB-C speed charging, a microphone on the ear cup and a foldable design. The T450BT only wins on weight and on having a 3.5 mm wired jack.
Which one is better for a child — the T450BT or the Tune 510BT?
No. Both list noise control as none, so neither actively cancels background noise. The on-ear cushions may block a little sound passively, but do not expect the quiet of an ANC model.
Yes. It has a 3.5 mm headphone jack, so it can be plugged in and used without Bluetooth. The JBL Tune 510BT does not list a 3.5 mm jack — its connectivity is USB for charging and wireless Bluetooth for audio.
