If you want a wired over-ear fit with 50 mm drivers and a standard headphone connection for a kid, choose OneOdio Over Ear Headphones; if you need wireless listening, long battery life, and a built-in microphone, choose Sony WH-CH520.
For a child who listens at home to music, videos, or a computer, the OneOdio’s over-ear design and wired connection are straightforward strengths. For a kid who moves between devices or needs headphones without a cable, Sony’s wireless design is the clearer fit. Neither is a neckband model, and neither is described as sweatproof or noise-canceling.
• OneOdio’s biggest strength: over-ear cups, 50 mm dynamic drivers, and a wired 3.5 mm connection; trade-off: no wireless listening or stated battery features.
• Sony’s biggest strength: Bluetooth listening with up to 50 hours of battery life, a built-in microphone, and connection to two devices; trade-off: on-ear fit and no headphone jack.
• OneOdio is for: a child who mainly listens from a compatible device with a headphone jack and prefers an over-ear design.
• Sony is for: a child who needs cordless listening, frequent device switching, or hands-free calls.
• The key difference: OneOdio prioritizes a direct wired setup; Sony prioritizes wireless convenience and battery endurance.
OneOdio is the more direct choice if the headphones will stay near a computer, tablet, keyboard, or other compatible audio source. Its over-ear fit and 50 mm dynamic drivers make the design feel oriented toward listening and monitoring rather than easy pocketable travel. The listed connection is wired, with a 3.5 mm jack, and the product information also identifies a 6.35 mm connection. That can be useful when the child’s listening setup includes equipment that accepts that larger plug.
For a kid, the absence of a battery requirement may be an advantage in a predictable setting: connect the cable to a compatible source and listen without tracking a charge cycle. The trade-off is equally plain. A cable can restrict movement, and a device without a suitable headphone connection will not work as a simple wireless source. The listed product details do not give a battery feature or Bluetooth option.

Sony WH-CH520: Who It's For
Sony WH-CH520 is a wireless, on-ear model for a child who wants to listen without a cable. Bluetooth 5.2 supports the cordless setup, and the headphones can connect to two Bluetooth devices at once. That multipoint feature can suit a child who moves between a laptop and phone, such as switching from a video on one device to a call on another.
Battery life is a major part of Sony’s appeal: the product information specifies up to 50 hours, along with USB Type-C charging and quick charging. The headphones also have a built-in microphone for hands-free calls. Their lightweight design, adjustable headband, soft ear pads, and swivel earcups are listed comfort and carrying features. EQ customization is available through Sony’s Headphones Connect app, so listeners can adjust sound preferences there.
• Best for a wired listening setup: OneOdio Over Ear Headphones. It has a wired connection and a listed 3.5 mm jack, with product information also identifying a 6.35 mm connection.
• Best for cordless listening: Sony WH-CH520. It uses Bluetooth, while OneOdio is listed as wired.
• Best for stated battery life: Sony WH-CH520. Its listed battery life is up to 50 hours, with USB Type-C charging and quick charging.
• Best for an over-ear fit: OneOdio. Sony is an on-ear model, so the choice comes down partly to how the child prefers headphones to sit.
• Best for calls: Sony WH-CH520. Its built-in microphone supports hands-free calling; no comparable microphone feature is listed for OneOdio.
• Best for switching between two devices: Sony WH-CH520. Its multipoint connection can pair with two Bluetooth devices at once.
• Best for connecting to compatible audio equipment: OneOdio. Its wired design and listed 3.5 mm and 6.35 mm connections suit setups that need a physical headphone connection.
• Best for a kid who does not want to manage a cable: Sony WH-CH520. Its Bluetooth connection removes the listening cable, though it does mean keeping the headphones charged.
The difference is not simply wired versus wireless. The fit changes too. OneOdio covers the ears; Sony rests on them. A child who dislikes pressure from on-ear pads may lean toward OneOdio’s format, while a child who wants a lighter-feeling, swivel design may prefer the Sony style. The product information does not establish that either fit will suit every child, so comfort preference is worth considering.
The use case also matters. A pair intended to stay at a desk can be wired without much inconvenience. A pair used around the house or between devices benefits more from wireless listening. For school, neither is a neckband headphone, and neither product sheet specifies features such as a school-focused microphone arrangement or noise cancellation. I would choose based on the actual listening devices and the child’s fit preference rather than assuming either is designed for every classroom.
Some shoppers arrive with a different need in mind, such as sweatproof sleep headphones or USB-C charging earphones for the gym. These are not those product types. OneOdio is a wired over-ear headphone, while Sony is a wireless on-ear headphone that charges by USB Type-C. The listed information does not describe either model as sweatproof or designed for sleeping, and Sony’s charging connector should not be confused with USB-C earphones: it is a charging connection, not the headphone’s audio connection.
Sound preferences may also influence the choice, but the available details do not establish a measured sound-quality winner. OneOdio lists 50 mm dynamic drivers and a frequency range of 20 Hz to 40 kHz. Sony lists dynamic drivers and a frequency range of 20 to 20,000 Hz, along with app-based EQ customization and DSEE processing for compressed music. Those specifications describe different design details; they do not, on their own, prove which one a particular child will prefer.
For everyday practical use, Sony has more listed conveniences: Bluetooth, multipoint, a microphone, a long stated battery life, and app-based sound adjustment. OneOdio’s case is simpler: over-ear design, wired playback, and physical connections that can suit compatible audio gear. A parent choosing for a child should also check that the intended listening source matches the headphone connection. A cable-based pick is only useful if the device has a compatible jack or adapter, while a Bluetooth pick needs a device that supports Bluetooth pairing.
My Verdict
I would choose OneOdio instead for a child who listens at a desk and specifically wants an over-ear fit with a wired connection.
For the broader everyday use case, Sony’s added flexibility makes it my pick, as long as an on-ear design suits the child.
I would choose based on fit and connection needs. OneOdio is wired and over-ear; Sony is wireless and on-ear, with a microphone and up to 50 hours of stated battery life.
The listed noise control for the WH-CH520 is none. It should not be treated as a noise-canceling model based on the product details provided.
No wireless connection is listed for OneOdio. Its connectivity is described as wired, so it needs a compatible physical headphone connection.
Sony WH-CH520 is the more convenient choice for that purpose because it can connect to two Bluetooth devices at once. OneOdio is wired, so moving it between sources means reconnecting the cable.
