If you want wired, over-ear headphones for listening, monitoring, and a direct cable connection, choose OneOdio DJ Hi-Res Over-Ear; if you need wireless on-ear headphones with long battery life and Bluetooth convenience for a kid, choose SONY WH-CH520. For most everyday family use, I’d lean toward the Sony; the OneOdio is the more specialized choice for a child who needs a wired listening setup.
• OneOdio’s biggest strength: 50 mm drivers, over-ear cups, a detachable cable with 3.5 mm and 6.35 mm plugs, and swiveling ear cups for single-ear monitoring.
• OneOdio’s main trade-off: it is wired, so the child needs a compatible audio jack and must manage a long coiled cord.
• Sony’s biggest strength: Bluetooth listening, up to 50 hours of battery life, multipoint connection, and a built-in microphone for calls.
• Sony’s main trade-off: it has no headphone jack, and its on-ear design rests on the ears rather than surrounding them.
• Choose OneOdio for a child using wired audio equipment or who benefits from over-ear cups and a long cable.
• Choose Sony for a kid who needs wireless listening, calls, and easier switching between two Bluetooth devices.
The OneOdio is a wired, over-ear headphone built around 50 mm dynamic drivers. Its spec sheet lists a 20 Hz–20,000 Hz frequency range and 110 dB sensitivity. Those figures describe the headphone’s audio specifications; they do not, on their own, tell a parent how loud a child should listen. For kid use, listening habits and adult supervision still matter.
Its practical advantage is its straightforward wired setup. The cable is detachable and includes 3.5 mm and 6.35 mm plugs, so it can connect to compatible audio equipment with either jack. The coiled cord stretches to 9.8 feet, which gives room to sit away from a connected TV or stereo. That same reach can be inconvenient for a child carrying the headphones around: a long cable needs attention and can get in the way. There is no Bluetooth connection, so a device without a compatible audio jack is not a match.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
The padded ear cushions, adjustable headband, and 90-degree swiveling ear cups make the design especially relevant to listening at a desk or working with music equipment. A child learning an instrument, recording, or using a mixer may appreciate the cable and single-ear monitoring option more than wireless convenience. The product information also lists a protective case, though the main design remains a wired headphone rather than a compact wireless travel set.
Who should skip this: Skip the OneOdio if the child needs Bluetooth, a built-in microphone for calls, or a headphone that avoids cable management.
The Sony WH-CH520 is an on-ear Bluetooth headphone with no headphone jack. It is a more natural fit for a child who listens from a Bluetooth-enabled phone, tablet, or computer and does not want a cable trailing from the device. Its listed Bluetooth range is 10 meters, though the connection still depends on the paired device and surroundings.
Battery life is a clear part of its appeal: Sony lists up to 50 hours, along with quick charging. The product information says a three-minute charge can provide up to 90 minutes of playback. That can be useful when headphones need a quick top-up before a trip or a long stretch of listening. It does mean the family needs to keep the headphones charged; unlike the OneOdio, the Sony cannot simply use its included wired audio connection as a fallback because it has no headphone jack.
The WH-CH520 has 30 mm dynamic drivers and a listed frequency range of 20 Hz–20,000 Hz. Its on-ear cushions, adjustable headband, and swiveling ear cups are designed for a light, easy-to-wear fit. The built-in microphone supports hands-free calls, and multipoint Bluetooth allows it to connect to two devices at once. For example, a child can switch between audio on a computer and a call on a phone without repeatedly pairing from scratch. Sony also offers sound customization through its Headphones Connect app, including EQ adjustments and DSEE processing for compressed music files.
Who should skip this: Skip the Sony if the child needs a wired connection to equipment with a 3.5 mm or 6.35 mm jack, or specifically wants over-ear cups.

For a kid who will mostly listen to music, videos, or calls from Bluetooth devices, I’d choose the SONY WH-CH520. The long listed battery life, built-in microphone, and multipoint connection make it the more flexible everyday option in my opinion.
I’d choose the OneOdio instead when the child needs a cable, a 6.35 mm connection, or single-ear monitoring for music work. Its strengths are real, but they serve a more specific setup.
Start with the child’s devices. The OneOdio needs an audio jack: its detachable cable offers 3.5 mm and 6.35 mm plugs, but that does not help if the intended device has neither connection. The Sony avoids that cable requirement by using Bluetooth, but it cannot switch to a wired connection if Bluetooth is unavailable or the battery runs down.
Next, consider where the headphones will be used. A long coiled cable can suit a child seated at a desk, instrument, TV, or stereo. It is less convenient for moving around. The Sony removes the cord, but wireless use means charging is part of the routine. Its multipoint feature may be helpful in a household where a child uses both a computer and a phone.
Fit matters too. The OneOdio’s padded over-ear cups and adjustable headband differ from the Sony’s on-ear cushions and swivel design. The sheets do not provide headband measurements or a child-specific fit range, so a parent should not assume either model will fit every child comfortably. If possible, check fit and comfort before relying on either one for long listening sessions.
Finally, match the headphone to the activity rather than to a search phrase. Neither model is an earbud: the OneOdio is wired and over-ear, while the Sony is wireless and on-ear. Someone searching for wireless earbuds for workout, wireless on ear headphones for exercise, or in ear earbuds for mobile gaming may actually be looking for a different form factor or use case. These two headphones can serve general listening, but their supplied specifications do not establish sweat resistance or other exercise-specific features.
For everyday Bluetooth listening and calls, the Sony is the more convenient match because it is wireless, has a built-in microphone, and lists up to 50 hours of battery life. The OneOdio makes more sense for a child using wired audio gear or needing its over-ear design and monitoring features.
No. The OneOdio is listed as wired and uses a detachable cable with 3.5 mm and 6.35 mm plugs. Choose the Sony if Bluetooth listening is essential.
No. The Sony has no headphone jack and connects wirelessly through Bluetooth. That makes it convenient with compatible devices, but unsuitable when a wired connection is required.
The OneOdio is the more suitable choice based on its included 3.5 mm and 6.35 mm plugs and 90-degree swiveling ear cups for single-ear monitoring. The Sony is designed around Bluetooth and does not provide a headphone jack.
