If you want long battery life and wired listening options for a kid, choose OneOdio A70; if you need active noise cancellation and a lighter wireless design, choose Sony WH-CH720N.
Neither is a one-size-fits-all pick. The better fit depends on whether your priority is connection flexibility or a more feature-rich wireless experience.
OneOdio A70 vs Sony WH-CH720N at a Glance
• OneOdio A70: Its standout advantage is up to 72 hours of battery life, plus Bluetooth and 3.5 mm/6.35 mm wired connections. Its trade-off is that it has no noise control.
• Sony WH-CH720N: Its key strength is active noise cancellation with adjustable ambient sound. Its trade-off is a shorter stated battery life of up to 35 hours and no headphone jack.
• Choose the A70 if you want long battery life, wired listening, or the ability to share audio through a cable connection.
• Choose the WH-CH720N if you want noise cancellation, calls, and the option to connect to two Bluetooth devices at once.
• For a kid: the A70 makes more sense when flexible wired connections matter; Sony is more compelling when adjustable listening modes are the priority.
The OneOdio A70 is an over-ear headphone built around long battery life and connection flexibility. It supports Bluetooth 5.2, but it can also be used with a 3.5 mm audio cable. Its 3.5 mm and 6.35 mm jacks give it a useful place in a setup that might include a compatible computer, instrument amplifier, or other wired audio source. That range of connection options is its clearest practical advantage over the Sony.
For a kid, that flexibility can be useful if the headphones will move between wireless listening and wired use. The stated battery life is up to 72 hours, compared with up to 35 hours for Sony, so the A70 requires less frequent charging under the specified battery-life figures. OneOdio also describes an audio-sharing setup: connect the main headphones to a device, then use the headphone jacks and a cable to connect another pair of headphones. That can suit a shared video or listening session, provided the needed cable and second headphones are available.
The A70 uses 40 mm dynamic drivers and has an over-ear design. Those details help describe the hardware, but they do not establish that it will fit every child comfortably or deliver a particular sound preference. Its stated frequency range is 20 Hz–20 kHz. One practical limitation is clear: its noise control is listed as none. It may be a straightforward choice for home listening or wired use, but it does not offer active noise cancellation or an ambient-sound mode like Sony.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
Who should skip it: Skip the A70 if active noise cancellation or adjustable ambient sound is essential to your choice.
The Sony WH-CH720N is the stronger fit for someone who wants wireless listening with more sound-control features. It has active noise cancellation using dual noise sensor technology and Sony’s Integrated Processor V1. It also offers adjustable Ambient Sound mode, with 20 settings described in the product information, so the listener can choose to let more of the surrounding environment through. That is a more adaptable feature set than the A70’s listed lack of noise control.
Sony’s stated weight is 192 g, and the product information describes a lightweight, restructured headband with more space around the ears. That may be appealing for longer listening sessions, though it cannot guarantee comfort for every child. The listed age range includes kids and teens, but the product also lists an adult age range; age labels alone do not establish a fit for a particular head. The WH-CH720N is wireless-only and has no headphone jack, so it is less flexible than the A70 if a wired connection is a must.
The battery life is up to 35 hours, and the supplied USB Type-C cable supports quick charging: the product information states that a three-minute charge can provide up to an hour of playback. Sony also supports multipoint Bluetooth connections, allowing pairing with two devices and switching between them. For families juggling a tablet and another Bluetooth device, that can be convenient. Beamforming microphones and Precise Voice Pickup Technology are included for hands-free calls, while the A70’s listed control feature is call control rather than Sony’s more detailed voice-pickup system.
Who should skip it: Skip Sony if you need a headphone jack, long stated battery life beyond 35 hours, or wired audio-sharing connections.
• Best for longer stated battery life → OneOdio A70. Its battery life is listed as up to 72 hours; Sony’s is up to 35 hours.
• Best for active noise cancellation → Sony WH-CH720N. Sony lists active noise cancellation and dual noise sensor technology; the A70 lists no noise control.
• Best for wired listening → OneOdio A70. It supports a 3.5 mm connection and a 6.35 mm jack, while Sony has no headphone jack.
• Best for choosing how much of the environment you hear → Sony WH-CH720N. Its Ambient Sound mode has 20 settings, alongside noise cancellation.
• Best for sharing audio through a wired setup → OneOdio A70. Its described connection method lets a second pair of headphones join a listening session through the headphone jacks.
• Best for switching between two Bluetooth devices → Sony WH-CH720N. It supports multipoint pairing with two devices.
• Best for hands-free calls → Sony WH-CH720N. Its beamforming microphones and voice-pickup technology are specifically described for clearer voice pickup.
• Best for a grey gaming headset search → neither is a confirmed match. The A70 is listed as silver and Sony as pink; neither data sheet describes a grey color. The A70 does offer wired connections that may be useful in some setups, but neither sheet establishes gaming-specific features.
Buying Considerations
Consider the listening environment carefully. Sony’s active noise cancellation may appeal in noisy settings, but neither product sheet establishes a safe listening level for a child, and noise cancellation should not be treated as a substitute for adult supervision. Sony’s Ambient Sound mode is intended to let environmental sound through at adjustable levels; that may be useful when awareness matters. The A70, by contrast, has no listed noise-control feature, so it does not provide the same way to adjust environmental sound through the headphones.
Controls and connection needs also separate the two. The A70 offers wired and wireless use, which can be useful when a device lacks Bluetooth or when you want to avoid relying on a wireless connection. Sony is wireless-only, but supports two-device Bluetooth pairing and hands-free calls. Neither product sheet lists touch controls: Sony uses push-button controls, and the A70 lists call control. So if you are looking for a touch control wireless headset for library use, neither is specifically described as touch-controlled. Sony’s noise cancellation may be a better match for reducing distractions, while the A70’s lack of noise control may suit someone who does not want that feature.
If you are comparing options for demanding work environments, keep the feature claims in proportion. Sony has active noise cancellation, but the information provided does not establish that it is a noise cancelling wireless headset for construction work or that it provides hearing protection. Neither product is described as protective equipment. For a child, the more useful decision is whether the everyday connection options, battery expectations, and sound-control features match the intended setting.
Finally, do not assume that a listed age range or lightweight design guarantees a proper fit. Sony’s product information includes kids and teens, and gives a weight of 192 g; OneOdio describes the A70 as an adult product. The sheets do not provide child-specific fit measurements for either model. If fit is central to the decision, check the current product information and consider the child’s comfort and ability to use the controls safely.
My Verdict
I would choose the OneOdio A70 for a kid if long battery life and wired flexibility are the main priorities.
I would choose Sony instead when active noise cancellation, adjustable ambient sound, and hands-free calling matter more.
For this comparison, my pick is the A70—but only if the lack of noise control is acceptable.
The A70 offers longer stated battery life and wired connections. Sony adds active noise cancellation, adjustable ambient sound, and hands-free calling. The better fit depends on which features matter most; neither sheet guarantees a particular child’s fit or comfort.
No. Its listed noise control is “None.” It supports Bluetooth and wired connections, but its product information does not describe active noise cancellation or an ambient-sound mode.
It is wireless and uses Bluetooth 5.2. Its product information lists no headphone jack, so it does not offer the wired listening option provided by the A70.
The OneOdio A70 is listed for up to 72 hours of battery life, while the Sony WH-CH720N is listed for up to 35 hours. Sony also supports quick charging, with a stated three-minute charge providing up to an hour of playback.
