If you want a wired, over-ear fit with a long cable and flexible jack options for a kid, choose OneOdio Over Ear Headphones; if you need wireless listening, long battery life, and easy switching between devices, choose Sony WH-CH520.
For a child who will use headphones mainly at home, OneOdio’s large ear cups and wired connection may be the more practical match. For one who listens on the move or switches between a tablet and phone, Sony’s Bluetooth design is more convenient.
OneOdio Over Ear Headphones vs Sony WH-CH520 at a Glance
• Sony’s biggest strength: Bluetooth listening with up to 50 hours of battery life, a built-in microphone, and multipoint connection for two devices. Trade-off: Its on-ear design rests on the ears rather than enclosing them.
• Choose OneOdio if a child will mostly listen near a computer, stereo, or other device with a compatible audio jack.
• Choose Sony if wireless use, calls, and switching between two Bluetooth devices matter more than a wired connection.
• For school routines: Sony is the more natural fit when the child’s listening device supports Bluetooth; OneOdio suits a desk setup with an available headphone jack.
OneOdio is a wired, over-ear model with 50 mm dynamic drivers and a frequency range listed as 20 Hz–40 kHz. Those driver specifications describe the hardware, not a guarantee that every listener will prefer its sound.
The large ear cups and padded cushions are designed to cover the ears, while an adjustable, stretchable headband allows the fit to be changed. The cups also swivel 90 degrees for single-ear monitoring. That feature is aimed more at monitoring and mixing than everyday school listening, but it may be useful for a young musician working with a keyboard, guitar, or recording setup.

Sony’s WH-CH520 is an on-ear Bluetooth headphone with Bluetooth 5.2 and no headphone jack. Its on-ear pads sit against the ears instead of surrounding them. That makes it a different kind of fit from OneOdio’s over-ear design, so the choice may come down to which style a child finds more comfortable. The headband is adjustable, and the ear cups swivel for easier handling and carrying.
The headline practical feature is up to 50 hours of battery life, alongside USB Type-C charging and quick charging. The supplied cable is USB-A to USB-C. Sony also describes a quick-charge option that can provide up to 90 minutes of playback from a three-minute charge. Those details may help when a child forgets to charge ahead of a trip, though the headphones still need periodic charging and cannot fall back to a wired connection.
For a child using both a tablet and a phone, multipoint connection allows the headphones to connect to two Bluetooth devices and switch between them. A built-in microphone supports hands-free calls, and the Sony Headphones Connect app offers EQ customization. Who should skip this: a child whose main device requires a 3.5 mm or 6.35 mm wired connection, since this model has no headphone jack.
• Best for a wired setup → OneOdio Over Ear Headphones. It connects through 3.5 mm or 6.35 mm jacks and includes both detachable plug options.
• Best for wireless listening → Sony WH-CH520. Bluetooth 5.2 removes the headphone cable, but the listening device must support Bluetooth.
• Best for long periods between charges → Sony WH-CH520. Sony lists up to 50 hours of battery life, plus USB Type-C charging and a quick-charge feature.
• Best for an over-ear fit → OneOdio Over Ear Headphones. Its padded cups are designed to cover the ears; Sony’s pads rest on them.
• Best for switching between a phone and another device → Sony WH-CH520. Multipoint connection supports two Bluetooth devices at once.
• Best for recording or monitoring equipment → OneOdio Over Ear Headphones. Its dual plug options and 90-degree swiveling cups suit compatible audio setups and single-ear monitoring.
• Best for hands-free calls → Sony WH-CH520. It has a built-in microphone, while the OneOdio data sheet does not list one.
• Best for a child who wants sound adjustment in an app → Sony WH-CH520. Its EQ Custom feature is available through the Sony Headphones Connect app.
Buying Considerations
For a child, start with the device they will use most. If it has a headphone jack and listening usually happens at a desk or in one room, OneOdio avoids battery management. The long coiled cable gives room to sit away from a connected TV or stereo, though it can be less convenient when moving between rooms or packing a school bag.
Fit deserves equal attention. OneOdio covers the ears; Sony rests on them. Consider the child’s preference for over-ear versus on-ear headphones and whether an adjustable headband suits them.
These are not interchangeable with other accessory categories. Neither model is a neckband headphone for school, neither is described as a sweatproof sleep headphone, and the Sony’s USB-C port is for charging rather than a listed USB-C audio connection. If the actual need is sweatproof sleep headphones or USB-C charging earphones for gym use, these two over-ear/on-ear headphones do not match that brief based on the available product details.
I would choose Sony WH-CH520 for a kid whose everyday device supports Bluetooth and who will benefit from long battery life, a microphone, and two-device switching. Those features make it the more flexible option for listening across a tablet and phone.
I would choose OneOdio instead for a child who listens mainly at home, needs a wired connection, or uses audio equipment with a 6.35 mm jack.
My deciding factor is how the child will connect: Sony for wireless convenience, OneOdio for wired flexibility.
Neither has a guaranteed fit for every child. OneOdio is over-ear and wired; Sony is on-ear and wireless. Choose based on the child’s preferred fit and the device they will use.
No. It includes a USB-A to USB-C cable for charging, not a wired audio connection.
They can connect to a device with a compatible 3.5 mm or 6.35 mm audio jack.
OneOdio is wired, so it does not rely on a rechargeable battery for listening. Sony lists up to 50 hours per charge. Sound preference is subjective: OneOdio is described as bass-focused, while Sony offers app-based EQ customization.
