Neither is a noise-cancelling model, so I would not choose either as a noise cancelling wireless headset for construction work. The OneOdio is wired and offers sound isolation through its padded over-ear cushions; Sony is wireless, with no listed noise control. Those distinctions matter more than brand familiarity here.
If you want a wired, over-ear headset with flexible device connections for a kid, choose OneOdio A71; if you need wireless listening, long battery life, and hands-free calls, choose Sony WH-CH520. For this oneodio vs sony headphones comparison, my quick pick for a child using headphones with a computer, keyboard, or other wired source is the OneOdio. Sony is the more convenient choice for a phone-first routine, but it sits on the ears and has no listed noise control.

OneOdio A71 vs Sony WH-CH520 at a Glance
• OneOdio A71: Over-ear fit, two plug sizes, and swiveling earcups make it flexible for wired listening and monitoring. The trade-off is that it needs a cable and is not a Bluetooth headset.
• Sony WH-CH520: Bluetooth, up to 50 hours of battery life, a microphone, and multipoint pairing suit everyday listening and calls. The trade-off is its on-ear fit and lack of listed noise control.
• Choose OneOdio for a kid who will use a wired device, wants the around-ear design, or may benefit from keeping one ear free while monitoring.
• Choose Sony for a kid who listens from a phone or tablet and needs wireless convenience, long battery life, or the option to switch between two paired devices.

The A71 is a wired, over-ear pair with soft padded cushions and an adjustable, stretchable headband. Its around-ear design is the more substantial fit of these two. The cushions are described as providing comfort and sound isolation, which could suit listening at home, working at a computer, or connecting to equipment that has a headphone output.
Its connections are a practical advantage. The included coiled cable is described as 6.6 to 9.8 feet long, and it has both a 3.5 mm plug and a 6.35 mm plug. That gives it a useful range of wired connections, including computers, laptops, amplifiers, keyboards, and guitars, without relying on Bluetooth. The trade-off is just as clear: a cable limits movement, and the A71 does not provide wireless listening or a built-in microphone in the listed features.
The swiveling earcups turn 90 degrees for single-ear monitoring, so a child can keep one ear free while listening or talking with someone nearby. A shared audio port also lets another pair connect for shared listening, without a splitter. I’d consider the A71 for a kid who mainly listens at a desk or uses wired instruments and equipment. I’d skip it if wireless freedom, phone calls, or a cable-free school routine is the priority.
The WH-CH520 is an on-ear Bluetooth headset made for a different routine: listening from a phone or another wireless device, making hands-free calls, and moving between two paired devices. Its built-in microphone supports calls, while multipoint connection lets it switch between two Bluetooth devices. That can be useful when a child alternates between a laptop and a phone, assuming both support Bluetooth.
Sony lists up to 50 hours of battery life, plus USB Type-C quick charging. The supplied charging information says three minutes of charging can provide up to 90 minutes of playback. Those features make the Sony less dependent on finding a wired headphone connection, but it still needs charging. It also has no headphone jack, so wired listening is not an option if the battery runs down.
The fit is on-ear rather than over-ear, with soft earpads, an adjustable headband, and swivel earcups. Sony also provides sound customization through its app, including EQ presets and options to save personal settings. I’d look at this model for a kid whose listening is mostly Bluetooth-based and who values easy calls or long stretches between charges. I’d skip it if a wired connection, around-ear cushions, or listed noise isolation is essential.
• Best for a wired computer, keyboard, guitar, or amplifier → OneOdio A71. Its 3.5 mm and 6.35 mm plugs are intended for connections to a range of equipment.

• Best for a kid who wants an over-ear fit → OneOdio A71. Its cushions go around the ear; Sony’s are on-ear.
• Best for long battery life → Sony WH-CH520. Sony specifies up to 50 hours, with USB Type-C charging. The OneOdio is wired and does not use a battery.
• Best for calls → Sony WH-CH520. It has a built-in microphone for hands-free calling; no microphone is listed for the OneOdio.
• Best for keeping one ear free while listening → OneOdio A71. Its earcups swivel 90 degrees for single-ear monitoring.

A few tempting search phrases point to features neither product actually offers. A touch control wireless headset for library use does not describe either one: the Sony uses push-button controls, while the OneOdio is wired. And if you’re looking for a grey gaming headset, the provided details do not establish that either model is grey or specifically designed for gaming. The A71 may connect to a computer through its wired plugs, but that alone does not make it a dedicated gaming headset.
For a kid who will mostly listen at home or use a wired computer or instrument connection, I’d choose the OneOdio A71. I prefer its over-ear fit, two plug options, and single-ear monitoring for that use. It is not the right pick for wireless listening or calls, though. If those matter more, I’d choose the Sony WH-CH520 instead.
I’d choose based on how the child listens. The OneOdio is wired and over-ear, while the Sony is wireless, on-ear, and has a built-in microphone. Neither product’s listed features establish a universal fit for every child.
No noise control is listed for the WH-CH520. It is not described as noise-cancelling, so I would not choose it when active noise cancellation is a requirement.
No. The A71 is a wired headset with 3.5 mm and 6.35 mm plugs. The Sony WH-CH520 connects wirelessly by Bluetooth and has no headphone jack.
Value depends on the current price and on which features you’ll use. Check the current price on Amazon, then weigh it against your needs: the OneOdio offers wired connections and an over-ear design, while Sony adds Bluetooth, a microphone, multipoint pairing, and long battery life.
