If you want wired, over-ear headphones with a long cable and flexible device connections for a kid, choose OneOdio DJ Hi-Res Over-Ear; if you need lightweight Bluetooth headphones with long battery life and hands-free calls, choose SONY WH-CH520.
OneOdio DJ Hi-Res Over-Ear vs SONY WH-CH520 at a Glance
• OneOdio’s biggest strength: over-ear cups, 50 mm drivers, and detachable 3.5 mm and 6.35 mm connections. Trade-off: it is wired, with no wireless listening or built-in noise control.
• Sony’s biggest strength: Bluetooth listening with up to 50 hours of battery life, multipoint connection, and a built-in microphone. Trade-off: it is on-ear, and it has no wired headphone connection for ordinary listening.
• Best for a child who listens at a desk or connects to compatible audio gear: OneOdio.
• Best for a child who wants wireless listening across several everyday activities: Sony.
OneOdio is a wired, over-ear headphone built around a 50 mm dynamic driver. Its large cups cover the ears, while padded cushions and an adjustable, stretchable headband offer ways to tailor the fit. The listed frequency range is 20 Hz to 40 kHz. The product information also lists an impedance of 32 ohms and sensitivity of 110 dB.
The detachable cable is 9.8 feet long and has both 3.5 mm and 6.35 mm plugs. That makes the headphone a sensible choice when a child mainly listens at a desk, uses a compatible keyboard or audio setup, or needs a long reach from a television or stereo to a chair. Its 90-degree swiveling ear cups can also be useful for single-ear monitoring, though that function is more relevant to mixing or DJ-style use than to ordinary kid listening.
I would consider OneOdio for a child whose listening happens in one place and whose devices have the right audio jack. I would skip it if the main need is to walk around without a cable, take calls hands-free, or connect to a device that lacks a 3.5 mm or 6.35 mm audio jack. The product lists no noise-control feature, so the padded cushions should not be mistaken for active noise cancellation.

SONY WH-CH520: Who It's For
Sony takes the portable route. The WH-CH520 is a wireless, on-ear Bluetooth headphone with a listed Bluetooth range of 10 meters. Its battery life is up to 50 hours, and quick charging is specified to provide up to 90 minutes of playback from three minutes of charging. Those details make it a strong match for a child who would rather avoid a dangling cable and does not want to charge after every short listening session.
Its built-in microphone supports hands-free calls, and multipoint lets it connect to two Bluetooth devices at once. That could help a child switch between a computer and a phone without repeatedly pairing, although the usefulness depends on the devices and how the child uses them. Sony also offers sound customization through its Headphones Connect app, including equalizer presets and custom settings, and DSEE processing for compressed music files.
The fit is different from OneOdio’s: Sony sits on the ears rather than around them. Its listed weight is 147 g, and the design includes an adjustable headband, soft ear pads, and swivel ear cups. I would choose it for a child who listens while moving around, watches videos on a Bluetooth-connected device, or wants the option of hands-free calls. I would skip it if the child needs a wired connection, prefers over-ear cups, or will use equipment that only offers a headphone jack.
• Best for a long wired reach → OneOdio DJ Hi-Res Over-Ear. Its 9.8-foot detachable cable is designed for connecting to compatible audio devices from a seat or desk.
• Best for wireless listening → SONY WH-CH520. It connects over Bluetooth, with a listed range of 10 meters.
• Best for longer stated battery life → SONY WH-CH520. Sony specifies up to 50 hours per charge, plus quick charging. OneOdio does not need a battery for playback because it is wired.
• Best for large, over-ear cups → OneOdio DJ Hi-Res Over-Ear. Its circumaural design goes around the ears, unlike Sony’s on-ear fit.
• Best for switching between two paired devices → SONY WH-CH520. Its multipoint feature supports connections to two Bluetooth devices at once.
• Best for compatible keyboards, mixers, or other audio gear with a jack → OneOdio DJ Hi-Res Over-Ear. It includes detachable 3.5 mm and 6.35 mm plugs.
• Best for hands-free calls → SONY WH-CH520. A built-in microphone is included; the OneOdio facts provided do not list one.
• Best for a child who wants simple, stationary listening → OneOdio DJ Hi-Res Over-Ear. The direct wired connection avoids battery charging and Bluetooth pairing, as long as the device has a compatible jack.
The distinction is more about routine than sound claims. OneOdio’s listed driver size and frequency range may catch the eye, but those figures alone do not prove that every listener will prefer its sound. Sony adds app-based EQ adjustment, while OneOdio offers a wired connection and two plug sizes. For a child, the deciding questions are practical: Where will the headphones be used? Does the device have a suitable jack, or is Bluetooth more convenient? Does the child prefer cups around the ears or pads resting on them?
The use cases also need to stay in perspective. Neither product is described as having noise control, so neither should be chosen on the assumption that it actively blocks surrounding sound. And although phrases like wireless on ear headphones for exercise may describe a search, the supplied specifications do not establish either model as sweat-resistant or designed for workouts. Sony removes the cable, but that alone is not proof of exercise durability.
The same caution applies if someone is searching for wireless earbuds for workout or in ear earbuds for mobile gaming. These are headphones, not earbuds, and OneOdio is not wireless. Sony is wireless and has a microphone, but the specifications do not establish gaming latency or a workout-specific design. For mobile gaming, check whether the particular device can use the Sony Bluetooth connection as intended; for equipment that requires a physical jack, OneOdio’s cable and plugs are the clearer fit.
I would choose the SONY WH-CH520 for most kids because Bluetooth, up to 50 hours of battery life, multipoint, and a built-in microphone support a broader everyday routine.
That is my opinion based on the listed features, not a claim that its on-ear fit will suit every child.
I would choose OneOdio instead for a kid who listens mainly at a desk and needs an over-ear design with a long, detachable cable and compatible plug options.
Before deciding, I would match the fit and connection type to the child’s actual device and listening habits.
Sony is the more flexible everyday choice if the child needs Bluetooth, a built-in microphone, and up to 50 hours of battery life. OneOdio makes more sense for a child who listens in one place and needs an over-ear headphone with a wired connection.
Can the OneOdio headphones connect wirelessly?
No wireless connection is listed for OneOdio. It is a wired headphone with a detachable cable and 3.5 mm and 6.35 mm plugs, so the device needs a compatible audio jack.
Noise control is listed as none. The product information supports Bluetooth, on-ear cups, a microphone, and app-based sound adjustment, but it does not support describing this model as noise-canceling.
Value depends on the current price and what features the child will actually use, so check the current price on Amazon before deciding. The more useful comparison is the feature fit: Sony brings wireless listening, multipoint, calls, and long stated battery life; OneOdio brings over-ear cups, a long cable, and two detachable plug options.
