If you want wireless listening, long battery life, and bass-focused sound for kids wireless, choose JBL Tune 520BT; if you need a simple wired pair with a swivel design, choose Sony ZX Series.
The main difference is straightforward: JBL is the more flexible option for everyday wireless listening, while Sony keeps things simple with a cable and 3.5 mm plug. For a child, the right choice comes down to whether wireless freedom and rechargeable battery life matter more than a connection that never needs charging.
• JBL Tune 520BT strength: Bluetooth 5.3, up to 57 hours of battery life, and sound customization through the JBL Headphones app. Trade-off: It needs charging and has no noise-control feature.
• Sony ZX Series strength: A 3.5 mm wired connection, a 1.2-meter cable, and swivel earcups for portability. Trade-off: It is not wireless and has no built-in microphone.
• Choose JBL for a child who listens from a Bluetooth phone or tablet and would benefit from fewer cables and long stretches between charges.
• Choose Sony for a child who uses a device with a headphone jack and prefers a simple wired setup without battery management.
The Tune 520BT is the stronger fit when wireless use is the priority. Bluetooth 5.3 lets it connect to a compatible device without a headphone cable, which can make it easier for a child to listen while moving around at home or on a trip. Its stated battery life is up to 57 hours, and a full recharge takes about two hours. A five-minute charge is described as providing three additional hours of music, a useful fallback when someone forgets to charge ahead of time.
Its sound profile is centered on JBL Pure Bass, and the JBL Headphones app offers EQ adjustments for listeners who want to tailor the sound. On-ear buttons handle playback and calls, while Voice Aware lets the listener hear their own voice during calls. Those features make it more versatile than a basic pair of headphones, though they also mean there is a battery and a set of controls for a child to learn. The headphones fold flat for easier packing, and the Bluetooth range is listed as 10 meters.

For a family shopping specifically for wireless headphones for kids, the JBL’s combination of Bluetooth and long battery life is a practical advantage. It can also make sense for older children who want app-based sound adjustments and hands-free calling. The trade-offs are equally clear: the listed noise control is none, and the on-ear design may not suit every child’s fit preferences. The product information also suggests adjusting the earpieces for fit; comfort should not be assumed from the feature description alone.
Who should skip it: Skip the JBL if you want a wired connection that does not need charging, or if noise control is a must-have.
The Sony ZX Series is a straightforward wired option. Its 3.5 mm stereo mini plug connects to devices that have a compatible headphone jack, and the 1.2-meter Y-type cable provides a direct connection without Bluetooth pairing or a rechargeable headphone battery. That can suit a child who uses a device with a headphone port and a parent who would rather not keep track of another charging routine. The cable does, however, limit how far the listener can move from the connected device.
Sony lists 30 mm dynamic drivers and a frequency range of 20 Hz to 20,000 Hz. Those specifications describe the driver size and the range of sound the headphones are designed to reproduce; they do not establish that the Sony will sound better than the JBL in every situation. The on-ear design is described as lightweight, and the earcups swivel for portability. Together, those details make the ZX Series a simple travel-oriented pick that can be folded or turned for easier packing.
The Sony may appeal to a child who wants uncomplicated listening, or to a family whose devices are already set up for wired headphones. It is not, however, a wireless model: it cannot connect over Bluetooth. The product information also lists no microphone, so it is not the straightforward choice for calls that require the listener to speak through the headphones. The design is pink, a factual detail some shoppers may care about, but color alone should not outweigh connection type and fit.
Who should skip it: Skip the Sony if your child needs Bluetooth, hands-free calls, or a listening setup without a trailing cable.
• Best for wireless listening → JBL Tune 520BT. It connects through Bluetooth 5.3, while the Sony needs a compatible 3.5 mm headphone jack.
• Best for long stretches between charges → JBL Tune 520BT. It is rated for up to 57 hours of battery life, although it still needs charging eventually.
• Best for avoiding headphone charging → Sony ZX Series. Its wired 3.5 mm connection does not require the headphone battery management the JBL does.
• Best for app-based sound adjustment → JBL Tune 520BT. The JBL Headphones app includes EQ customization; no equivalent app feature is listed for the Sony.
• Best for hands-free calls → JBL Tune 520BT. Its on-ear controls support calls and Voice Aware. Sony lists no microphone.
• Best for a child whose device has only a headphone jack → Sony ZX Series. Its wired plug is the more direct match, provided the device has a compatible port.
• Best for folding or packing into a bag → JBL Tune 520BT. It folds flat; the Sony earcups swivel for portability, but the supplied information does not describe the same flat-folding design.
• Best for a no-frills wired setup → Sony ZX Series. There is no Bluetooth pairing or headphone charging, but the cable is part of the everyday setup.
Before choosing, check how the child’s device connects. The JBL is wireless, so Bluetooth compatibility matters. The Sony requires a 3.5 mm jack. If the device does not have that port, the Sony may not be a direct fit; the listed product details do not specify an adapter.
Think about the listening routine, too. The JBL’s battery life and quick-charge detail are helpful when the headphones are used often, but a rechargeable model adds one more item to keep charged. Sony avoids that task, yet its cable can restrict movement and may need to be managed in a backpack. Neither product lists noise control, so shoppers looking specifically for noise-canceling features should not assume either pair provides them.
The intended use matters as much as the connection. These are on-ear headphones, and the provided specifications do not establish a child-specific fit or volume-limiting feature. For gaming, either could suit a child who simply needs audio, depending on the device connection. But the Sony’s lack of a microphone and the JBL’s call features make them different choices if voice chat matters. Neither product is described as waterproof, so searches for the best waterproof in ear headphones or the best IPX7 waterproof Bluetooth headphones for call center are looking for a different kind of product. Those phrases do not describe either of these on-ear models.
My Verdict
I would choose the Sony ZX Series instead when the child’s device has a headphone jack and a simple wired connection is the priority. For my wireless-first pick, the JBL is the more useful match.
Yes. The JBL uses Bluetooth 5.3 for wireless listening and has no headphone jack listed. Its battery life is up to 57 hours, so it will need recharging.
No. The Sony ZX Series connects through a wired 3.5 mm stereo mini plug and has a 1.2-meter cable. It does not use Bluetooth.
The JBL is the more suitable choice based on the listed features: it has on-ear call controls and Voice Aware, which lets the listener hear their own voice while talking. Sony lists no microphone.
Neither product’s listed features describe waterproofing or noise control. If those features are essential, look for a model whose specifications explicitly confirm them rather than assuming they are included here.
