If you're looking for a great pair of volume-limited headphones for kids, the Puro Sound Labs PuroQuiet Kids Headphones are the best that we've tested. These are a bit pricier than our previous favorite—the Puro BT2200—but they offer a killer new feature: noise cancellation. Though it may seem like a luxury feature for many children, it's an awesome addition for kids who have sensory issues.
For other children, the noise-cancellation helps reduce the urge to crank the volume to the absolute max. Though volume-limiting headphones are critical for protecting your child's hearing, the recommended max of 85dB(a) simply isn't very loud. These headphones help solve for that by further cutting down ambient noise.
In our lab tests, the PuroQuiets were some of the best noise-canceling headphones we've tested, cutting down a significant amount of ambient noise with no major technical issues. Though our tests showed they could get up to around 87 decibels(a), that's still near the recommended level that experts deem safe for most children up to 8 hours.
The main drawback here is the price, but Puro frequently discounts these. Headphones that cost around $100 (or higher) can be pricey for younger kids who are likely to forget them somewhere (or simply break them), but for an older kid wanting nicer headphones, these are worth the investment.
The wireless capability ensures that your kid can't easily circumvent the volume protections, provide a tangle-free listening experience and they will work with a wider range of modern devices including newer smartphones that don't have built-in headphone jacks. Just note that if the battery dies you can use the included cable, but the volume limiter on the cable only works when plugged in the right way.
