If you want long battery life, volume limits, and an over-ear design for a kid, choose iClever BTH12; if you need a foldable, app-adjustable wireless headphone with JBL’s bass-focused sound, choose JBL Tune 520BT.
For kid-focused listening, I’d lean toward the iClever because it offers selectable volume limits and a wired option.
iClever BTH12 vs JBL Tune 520BT at a Glance
• iClever BTH12 strength: over-ear fit, selectable 74 or 85 dBA volume limits, and up to 85 hours of stated playtime. Trade-off: its LED lighting may be a distraction, and it is heavier than the JBL according to the listed weights.
• JBL Tune 520BT strength: Bluetooth 5.3, app-based EQ customization, and a flat-folding design. Trade-off: it has no headphone jack, and the supplied details do not list a selectable volume limit.
• For a kid who needs a cord option: iClever BTH12, which includes a 3.5 mm jack and can also connect wirelessly.
• For someone who wants app sound adjustments: JBL Tune 520BT, which works with the JBL Headphones app for EQ changes.
• Who each fits: iClever is the more child-oriented pick; JBL suits a listener who prefers on-ear headphones and customizable sound.
The BTH12 is the more explicitly kid-focused design here. It sits over the ears and includes a volume limit that can be set to 74 or 85 dBA using a combination of keys. That gives a parent a concrete control to consider for a child’s listening routine. The limit is not a substitute for supervising listening habits, but it is a feature the JBL’s supplied details do not list.
Battery life is a clear strength on paper: iClever states up to 85 hours of playtime. It charges over USB-C, and the feature information says a 10-minute charge can provide seven hours of playtime. Bluetooth 5.2 handles wireless listening, while the 3.5 mm jack gives the BTH12 a wired option. That flexibility can help when a device’s battery is low or a wired connection is more convenient.

The BTH12 also has four lighting modes, a built-in microphone, and a stated 40 mm speaker unit. I’d choose it for a child who wants colorful headphones and for a family that values long stated battery life, volume-limit settings, and the option to use a cable. I’d skip it if the lights would be distracting or if a lighter listed weight is a priority: the product information lists it at 280 g, compared with 157 g for the JBL.
The Tune 520BT takes a more general-purpose approach. Its on-ear design folds flat for carrying, and the product information lists Bluetooth 5.3. JBL also provides an app that lets the listener adjust EQ, so it has an advantage for someone who wants to change the sound profile rather than stick with one preset approach.
JBL highlights its Pure Bass sound and Voice Aware for calls. With Voice Aware, the listener can hear their own voice while talking. The ear-cup buttons manage playback and calls, and the headphones offer up to 57 hours of stated battery life. USB-C charging is listed, with a stated two-hour charge time and a feature claim that a five-minute charge adds three hours of music.
I’d consider the JBL for an older child, teen, or adult who prefers on-ear headphones, wants to fold them into a backpack, and will make use of the EQ app. The key trade-off for a kid-focused purchase is that the provided details do not list a volume limit or a wired jack. The JBL is also described as an adult product in its age-range information, while the iClever listing explicitly includes kids.
• Best fit for kid-focused controls → iClever BTH12. It has selectable 74 or 85 dBA volume limits; the JBL’s supplied details do not specify one.
• Best for stated battery life → iClever BTH12. Its stated maximum is 85 hours, compared with up to 57 hours for the JBL.
• Best for a wired listening option → iClever BTH12. It includes a 3.5 mm jack; the JBL has no headphone jack listed.
• Best for adjustable EQ → JBL Tune 520BT. Its companion app lets the listener tailor the sound.
• Best for a fold-flat design → JBL Tune 520BT. Its listed design folds flat for easier packing.
• Best for the lighter listed weight → JBL Tune 520BT. The product information lists 157 g, while the iClever is listed at 280 g.
• Best for LED lighting → iClever BTH12. It offers four lighting modes, which may appeal to a child but may not suit a listener who wants a plainer design.
• Best for calls with a sidetone-style feature → JBL Tune 520BT. Voice Aware lets the wearer hear their voice during calls; the iClever has a built-in microphone and call controls, but its details do not list that same feature.
These are headphones, not earbuds. Neither product’s supplied details describe a clip-on earbud design or an in-ear shape for sleeping. If you are searching for the best clip on earbuds for video calls or the best usb c charging in ear earbuds for side sleepers, neither model matches that form factor. For calls, both have relevant features: the iClever has a built-in microphone, while the JBL adds Voice Aware.
My Verdict
I’d buy the iClever BTH12 for a kid because its selectable volume limits, over-ear design, 3.5 mm jack, and longer stated battery life make it the more child-oriented and flexible option.
The JBL Tune 520BT is the more appealing choice for someone who values EQ customization, fold-flat storage, and a lighter listed weight.
But for the use case at the center of this comparison, I’d choose iClever.
I’d favor the iClever for a kid because it includes selectable 74 or 85 dBA volume limits and a wired option. The JBL may still suit an older child who wants app-based EQ and a folding design, but its supplied details do not list a volume limit.
The iClever BTH12 is listed with up to 85 hours of playtime; the JBL Tune 520BT is listed with up to 57 hours. Those are stated maximums, not a guarantee of the same runtime in every use.
The iClever includes a 3.5 mm headphone jack, so it has a wired option in addition to Bluetooth. The JBL Tune 520BT has no headphone jack listed and is described as wireless.
Both include call-related features. The iClever has a built-in microphone and call controls; the JBL has hands-free call controls and Voice Aware, which lets the listener hear their own voice. The supplied information does not establish which has clearer call audio.
