If you want closed-back studio headphones with a neutral sound focus, choose AUDIX A140; if you need wired over-ear headphones with a natural wood design and broad device compatibility, choose SIVGA SV021. For children, neither is specifically described as a child-sized model, so fit matters more than a label. The A140 leans toward monitoring and reduced microphone bleed; the SV021 leans toward Hi-Fi listening and a distinctive wood build.
• AUDIX A140’s biggest strength: a closed-back design intended for focused listening, with a neutral sound profile and features suited to studio work.
• AUDIX A140’s trade-off: it is a wired studio-style headphone, not a wireless option for children who need earbuds or freedom from a cable.
• SIVGA SV021’s biggest strength: a 32-ohm wired design intended to work with phones, tablets, and computers, plus a distinctive wood enclosure.
• SIVGA SV021’s trade-off: it is also wired and over-ear; neither model offers wireless listening or an explicitly child-focused fit.
• Who should choose which: pick the A140 for monitoring-oriented listening and microphone use; pick the SV021 for everyday wired music listening and its wood design.
The AUDIX A140 is built around a closed-back, over-ear design and 40 mm drivers. Its stated purpose is accurate, relatively uncolored sound for critical listening, recording, playback, and music enjoyment. That makes it the more work-oriented option here. The circular ear cups swivel 90 degrees, which can be useful for single-ear monitoring, while the design is also intended to limit sound leaking into microphones.
For a household where a child is learning music production, recording, or simply listening near someone using a microphone, those features give the A140 a clear role. Soft padding on the ear cups and headband is intended to support longer listening sessions. The detachable 5.9-foot cable, 1/8-inch connector, included 1/4-inch adapter, and protective carry case also make it practical to move between a desk and a storage spot.

The SIVGA SV021 is a wired, closed-back, over-ear headphone with 50 mm dynamic drivers and a 32-ohm impedance. Its design is aimed at Hi-Fi music listening, and its low impedance is described as making it suitable for devices such as phones, tablets, and computers. That flexibility is appealing if a child will use one pair with several everyday devices rather than a dedicated studio setup.
Its natural wood enclosure gives it a different character from the A140’s studio-focused design. The product information describes a handcrafted wood build, an adjustable headband, and soft memory-foam earpads covered in high-protein material. The earpads are detachable and replaceable. It comes with a dual 2.5 mm to 3.5 mm cable, a 3.5 mm-to-6.35 mm adapter, and a hemp bag.
The SV021 makes more sense for someone who values wired music listening and a distinctive build over studio-monitoring features. But it is not a wireless headphone, and the supplied details do not identify a child-specific fit or any noise-cancelling system. The adjustable headband may help accommodate different head sizes, but that alone does not confirm that it will fit every child comfortably.
• Best for studio-oriented listening → AUDIX A140. Its stated neutral sound approach and recording-focused design make it the more natural match for monitoring and critical listening.
• Best for reducing microphone bleed → AUDIX A140. Its closed-back design is specifically described as minimizing noise leaking into microphones.
• Best for single-ear monitoring → AUDIX A140. The ear cups swivel 90 degrees, a practical detail when listening with one ear.
• Best for use with phones, tablets, and computers → SIVGA SV021. Its 32-ohm impedance is described as making it suitable for a broad range of common devices.
• Best for a wood-enclosure look → SIVGA SV021. Its natural wood construction gives it a more distinctive appearance than the A140’s studio-oriented presentation.
• Best for replaceable earpads → SIVGA SV021. Its detachable pads are described as easy to replace, which may matter to a buyer considering ongoing upkeep.
• Best for portability features → AUDIX A140. It includes a protective carry case and a detachable 5.9-foot cable.
• Best for children who want wireless freedom → Neither. Both are wired, over-ear models. If the priority is a wireless option, these two do not meet it.
The phrase “best headband headphones for children” can make this choice sound simpler than it is. The available facts do not establish either model as child-sized, and a headband that adjusts is not automatically a good fit for a younger listener. Check fit and comfort in person when possible, and consider whether a cable suits the child’s routine.
My Verdict
I would choose the AUDIX A140 for a child who will use headphones for music practice, recording, or listening near a microphone. Its closed-back construction, monitoring-oriented details, and included carry case give it the clearer purpose in that setting. For children, I would still make fit the deciding check: the product details do not describe a child-specific size. If the use is ordinary music listening across phones and computers, I’d consider the SV021 instead.
No. Both are wired, over-ear headphones. The A140 has a detachable 5.9-foot cable; the SV021 includes a dual 2.5 mm to 3.5 mm cable.
It depends on the listening setup, not a stated child-specific feature. The A140 is geared toward accurate, studio-style listening, while the SV021 is designed for Hi-Fi listening and is described as compatible with phones, tablets, and computers. Neither is identified as a child-sized model.
The A140’s closed-back design is described as helping block external noise and reduce microphone bleed.
