JBL JR310BT vs Belkin SoundForm Mini Wireless
Quick take: The Belkin SoundForm Mini Wireless costs $1 less.
Which one to buy
An 85dB limit is printed on the box of both of these $33-34 kids' headphones, and lab measurements say neither meets it. The JR310BT got close enough to work as a backstop, at about 94dB at maximum over Bluetooth. The SoundForm Mini measured about 98dB over Bluetooth and 109dB through its aux cable, among the worst results for any major kids' headphone. If the limiter is why you're shopping, the JBL is the less bad of the two, and either way the tablet's volume cap is what actually protects their hearing.
The Belkin wins on practical features. It includes an aux cable for plane seatbacks, wired-only school Chromebooks and dead batteries, while the JBL is Bluetooth-only and can't even play while charging. The Belkin's battery is enormous: rated at 30 hours, it ran about 82 hours in independent lab testing, against the JBL's roughly 39. It also comes with a 2-year warranty, and its plain design appeals to kids who are too old for cartoon-style headphones.
The JBL is gentler. It weighs 115g and is sized for ages 3 to 10, though some pressure-sensitive kids still complain. The Belkin's clamp is tight enough that some kids refuse it within an hour, and reviewers rate its sound among the weakest in the class. The JBL's sound is basic too, but nobody singles it out.
JBL JR310BT
For a younger child, roughly 3 to 8, where a lighter fit and a limiter that comes closer to its promise matter more than wired playback.
Belkin SoundForm Mini Wireless
Worth it for an older kid who needs wired use on planes or at school and won't mind the clamp. Set the device's volume cap first, especially when the cable is plugged in.

JBL JR310BT vs Belkin SoundForm Mini Wireless: common questions
Is the JR310BT's or the SoundForm Mini's volume limiter more trustworthy?▾
The JBL's, though neither meets 85dB. Lab measurements put the JBL at about 94dB at maximum and the Belkin at about 98dB over Bluetooth and 109dB wired. For both, set the volume limit on the tablet or phone.
Can the JR310BT or the SoundForm Mini plug into a plane seatback screen?▾
Only the Belkin, because it includes a 3.5mm aux cable. The JBL has no wired option. Remember that the Belkin's wired path has no effective limit, so control the volume at the source.
How often will we need to charge the SoundForm Mini versus the JR310BT?▾
In independent lab testing, the Belkin ran about 82 hours, so roughly a monthly charge, and the JBL about 39, so roughly weekly for a kid using them an hour or two a day. Both quick-charge: 10 minutes gives about 3 hours on the Belkin, and 5 minutes gives about 2 on the JBL.
