If you want compact earbuds for for kids wireless listening and the choice to use one earbud at a time, choose JBL Vibe 100TWS; if you need an on-ear fit and longer stated battery life, choose Sony WH-CH520.
For this Sony vs JBL headphones comparison, the deciding difference is simple: earbuds that can be used separately, or a lightweight on-ear design with up to 50 hours of playback.
I’d match the JBL to someone who wants a small, flexible listening setup and the Sony to someone who prefers headphones that rest over the ears.
• JBL Vibe 100TWS: Its key strength is true wireless listening with either earbud on its own or both together; its trade-off is up to five hours of playback from the earbuds before returning to the charging case.
• Sony WH-CH520: Its key strength is up to 50 hours of stated battery life, with quick charging; its trade-off is an on-ear fit, which may not suit someone who prefers earbuds.
• JBL is for listeners who want a choice of one or two earbuds, three ear-tip sizes, and deep bass from 8 mm drivers.
• Sony is for listeners who want on-ear headphones, app-based sound adjustment, and the option to pair with two Bluetooth devices at once.
The JBL Vibe 100TWS is a true wireless earbud set built around flexibility. You can listen with both earbuds, or use just the left or right one. That single-ear option is useful when you want to keep one ear open, and it also lets you keep one earbud charging in the case while listening with the other. The earbuds provide up to five hours of playback; the case adds another 15 hours, for up to 20 hours combined.
JBL lists an 8 mm driver and its Deep Bass Sound as the main audio draw. That points toward a bass-focused listening character, which may appeal to music fans who like a fuller low end. The fit matters: the set includes three sizes of silicone ear tips, so you can try to find a snug fit. A secure seal can affect both sound and call performance, making the choice of tip more than a comfort detail.
Hands-free calls are supported, and the earbuds can manage calls and sound over Bluetooth. The listed wireless range is up to 30 feet, though the actual connection can vary with walls, surroundings, and nearby electronics. There is no noise control, and the product information says no voice assistant feature is available, so I would not choose these for noise reduction or voice-assistant access. The charge time is two hours.

The Sony WH-CH520 takes the opposite approach: it is a wireless on-ear headphone rather than a pair of separate earbuds. Its stated battery life is up to 50 hours, and USB-C quick charging can provide up to 90 minutes of playback after three minutes of charging. That combination is appealing if you would rather charge less often and want a quick top-up option when you do need one.
The on-ear design has soft earpads, an additional head cushion, and silent joints. Sony describes the headphones as lightweight, while the product information lists a weight of 310 g. The swivel design is intended to make them easier to carry compactly. These details suit someone who wants headphones with a headband and earcups rather than silicone tips, although comfort is personal and an on-ear fit may not be everyone’s preference.
There is also more flexibility for shaping the sound. Sony’s Headphones Connect app offers EQ presets and the ability to create and save custom settings. A built-in microphone supports hands-free calls, and the headphones can connect to two Bluetooth devices at the same time. They also support Google Assistant and Siri, and the listed Find My Device app feature can help locate missing headphones. Like the JBL, these have no noise control.
Who should skip this: Skip the Sony if you specifically want small in-ear earbuds, or if you need noise control.
• Best for using one ear at a time → JBL Vibe 100TWS. Either the left or right earbud can work on its own, and the unused one can charge in the case.
• Best for longer stated battery life → Sony WH-CH520. Sony lists up to 50 hours, compared with up to 20 hours combined for the JBL earbuds and case.
• Best for deep-bass-focused listening → JBL Vibe 100TWS. Its 8 mm drivers are paired with JBL’s Deep Bass Sound branding.
• Best for changing the sound profile → Sony WH-CH520. The app includes EQ presets and lets you make and save custom settings.
• Best for choosing an ear-tip fit → JBL Vibe 100TWS. Three silicone tip sizes give you options for finding a comfortable, snug fit.
• Best for switching between two Bluetooth devices → Sony WH-CH520. It can be paired with two devices at once.
• Best for quick charging → Sony WH-CH520. Three minutes of charging is listed as enough for up to 90 minutes of playback.
• Best for listening without wearing a headband → JBL Vibe 100TWS. Its earbuds sit in the ears, while the Sony rests on them.
For children, I would consider the fit and charging routine as carefully as the headline battery figures. The JBL offers three tip sizes and separate earbuds, but each small earbud needs to be kept track of. The Sony avoids separate buds and tips, but its on-ear fit may feel different from earbuds. Neither product’s listed information gives a child-specific fit or noise-control feature, so those details should not be assumed.
I’d choose the Sony WH-CH520 for my everyday listening because its up-to-50-hour battery life, quick charging, and app-based EQ make it the more flexible option for longer stretches between charges.
For for kids wireless listening, though, I’d lean toward the JBL if the child prefers earbuds and would benefit from using one at a time.
My choice would change with fit: the JBL suits someone who wants true wireless earbuds, while the Sony is the clearer pick for someone who prefers on-ear headphones.
Think about where the headphones will be used most. The JBL’s earbuds are separate, and either one can be used alone. That can be handy when you want to keep one ear free, but it also means keeping track of two small earbuds and their charging case. The Sony’s headband and on-ear cups make it a different kind of carry; its swivel design is intended to make it more compact when packed.
Battery claims also describe different routines. The JBL’s earbuds provide up to five hours before the case becomes part of the charging plan, with up to 20 hours combined. The Sony lists up to 50 hours, plus a quick-charge option. Those figures may help you choose between frequent short sessions and longer periods away from a charger, but neither figure should be treated as a promise of identical playback in every situation.
Neither set lists noise control. For quiet music or calls, both provide wireless Bluetooth listening and a built-in microphone or hands-free calling features, but their shapes and wearing styles remain quite different.
The JBL may appeal to shoppers comparing cheap on ear headphones, but it is not an on-ear model; it is an in-ear set. The Sony is the on-ear option here. Neither product is described as a neckband, so shoppers specifically searching for neckband headphones for nurses should know that these two designs do not match that form factor.
For either product, check the current price on Amazon using the page’s price button. The choice between them is easier to make on design, battery routine, and features than on a price figure alone.
FAQ
Neither product’s listed details include noise control. If reducing surrounding noise is essential, these specifications do not establish that either model will provide it.
Yes. The JBL can be used with the left earbud, the right earbud, or both. You can also leave one earbud charging in the case while using the other.
Both support hands-free calling: the JBL manages calls through its earbuds, and the Sony has a built-in microphone. The product details do not provide comparable call-quality test results, so the fit and preferred wearing style may be more useful factors.
