If you want wired over-ear headphones for focused listening and connecting to different audio jacks, choose OneOdio DJ Hi-Res Over-Ear; if you need wireless convenience and long battery life for a kid, choose SONY WH-CH520.
OneOdio DJ Hi-Res Over-Ear vs SONY WH-CH520 at a Glance
• OneOdio’s biggest strength: over-ear design, 50 mm drivers, and dual 3.5 mm and 6.35 mm jacks; its main trade-off is that it is wired, not wireless.
• Sony’s biggest strength: Bluetooth listening with up to 50 hours of battery life; its main trade-off is that the on-ear design and lack of a headphone jack limit how it can be worn and connected.
• OneOdio is for: a child using compatible wired equipment at home, especially when a larger over-ear fit and sound isolation are useful.
• Sony is for: a child who needs easy wireless listening, portable headphones, or a built-in microphone for calls.
• The quick call: choose by connection first. OneOdio needs a cable; Sony needs a charged battery and a Bluetooth source.
OneOdio is the more straightforward pick for a kid who listens at a desk, uses wired equipment, or needs headphones for a setup involving a computer, keyboard, or guitar. Its over-ear placement surrounds the ears, while the 50 mm dynamic drivers are larger than Sony’s 12 mm drivers. Those details make it the more studio-oriented design of the two, not an automatic promise of better sound for every listener.
The dual 3.5 mm and 6.35 mm jacks are a practical distinction. A standard 3.5 mm connection works with many everyday audio devices, while the larger 6.35 mm connection can suit compatible audio equipment. The model is wired, so there is no Bluetooth pairing or battery to manage. That keeps the connection simple when the child is seated nearby, but the cable limits movement and requires a compatible headphone output. Sound isolation is listed, though the sheet does not specify active noise cancellation.
The trade-off is its more adult, equipment-focused design. The product information identifies it as adult headphones, and it provides no child-specific fit or volume-limiting feature. It also weighs 10.56 ounces, so I would consider fit and comfort carefully for a younger child rather than assuming an over-ear style will suit everyone. The included protective case is useful for putting the headphones away, but it does not change the wired nature of the setup.

SONY WH-CH520: Who It's For
Sony is the easier everyday choice for a kid who listens from a phone, tablet, or laptop that supports Bluetooth. Its on-ear cups swivel, the headband adjusts, and the ear pads and head cushion are described as soft. The product information also identifies the headphones as lightweight, which may appeal to a child who wants to put them on and take them off throughout the day. These are on-ear headphones, however, so they rest on the ears rather than enclosing them.
Battery life is the headline practical advantage: Sony lists up to 50 hours of listening on a charge. Quick charging is also specified, with three minutes of charging providing up to 90 minutes of playback. That can help when the battery is low before a trip or a listening session, though it still means the headphones need charging eventually. Bluetooth 5.2 and a listed range of 10 meters support a cable-free setup, but the actual source still needs to be within a usable connection range.
Who should skip it: Skip Sony if the child must use a wired 6.35 mm or 3.5 mm output, or if an over-ear fit is the priority.
• Best for wireless listening → SONY WH-CH520. It uses Bluetooth and has no headphone jack, so there is no cable connecting the headphones to the device.
• Best for a wired desk setup → OneOdio DJ Hi-Res Over-Ear. Its 3.5 mm and 6.35 mm jacks suit compatible computers and audio equipment.
• Best for long stretches between charges → SONY WH-CH520. Its listed battery life is up to 50 hours, with quick charging as a backup when the battery is low.
• Best for a larger over-ear design → OneOdio DJ Hi-Res Over-Ear. It sits around the ears and uses 50 mm dynamic drivers.
• Best for calls → SONY WH-CH520. A built-in microphone supports hands-free calling, a feature not specified for OneOdio.
• Best for switching between two devices → SONY WH-CH520. Its multipoint connection can link two Bluetooth devices at once.
• Best for connecting to a 6.35 mm output → OneOdio DJ Hi-Res Over-Ear. Sony has no headphone jack, while OneOdio lists both 3.5 mm and 6.35 mm connections.
• Best for a workout or active movement → neither is a clear exercise pick. Sony is wireless, but it is an on-ear headphone; OneOdio’s cable can restrict movement. Neither data sheet identifies a workout-specific design.
These are headphones rather than earbuds, so someone searching for wireless earbuds for workout or in ear earbuds for mobile gaming is looking at a different form factor. For a child who plays games on a device, the deciding question here is whether that device supports Bluetooth or has a compatible headphone jack. Sony offers wireless convenience, while OneOdio offers wired connections; neither product sheet specifies gaming latency or a gaming microphone setup.
The same distinction applies to wireless on ear headphones for exercise. Sony matches the wireless, on-ear wording, but the provided information does not describe sweat resistance or an exercise-focused fit. I would not assume either model is designed for workouts simply because one has Bluetooth.
Start with the child’s device. If it has Bluetooth and the goal is casual listening around the house, Sony avoids cable management. If the listening source uses a 3.5 mm or 6.35 mm headphone output, OneOdio gives you those wired options. Check the actual device connection before choosing; the two models are not interchangeable in how they connect.
Next, consider how the headphones sit. OneOdio is over-ear, and Sony is on-ear. That is a meaningful fit difference, not just a styling detail. Some children may prefer cups that go around the ears; others may prefer a lighter, swiveling on-ear design. The provided specifications do not give child-specific sizing, so the adult age-range descriptions are worth keeping in mind.
Also think about the listening routine. Sony’s battery life and microphone are useful for a child who moves between media and calls, but the battery must be recharged. OneOdio avoids charging because it is wired, but the cable can restrict movement. Its sound-isolation feature is listed, while Sony lists no noise control. Neither sheet gives a volume limit, durability testing, or water resistance, so I would not treat either as specially designed for child safety, rough handling, or exercise.
If current price matters to your decision, check the current price on Amazon. The better fit here depends first on connection, wearing style, and whether wireless features are genuinely useful for the child.
For a kid who mainly listens wirelessly from a phone or laptop, I would choose the SONY WH-CH520. Its Bluetooth connection, up-to-50-hour battery life, built-in microphone, and multipoint pairing make it the more convenient everyday option. I would choose OneOdio instead for a child using wired audio equipment who specifically needs over-ear headphones and both jack sizes. My pick for the broader kid-use case is Sony, but only if the on-ear fit and Bluetooth setup suit the child.

They may suit a child if the connection and fit work for that child, but the product information describes both as adult headphones. Neither data sheet specifies a volume limiter or child-specific sizing, so those details should not be assumed.
