My kids gave the sound quality a thumbs up, but when your point of reference is a pair of old earbuds or your dad's larger, heavier over-the-ear headphones, anything that fits right is going to be better. And honestly, it was the fit and comfort of the headphones that my kids liked the most. They liked the look of them, too, and since they're made from aluminum they're more durable than the plastic competition. Left and right markings inside the earcups made it easier for them to know how to put them on and the controls are large enough for them to easily use without taking them off first.
After the fit, the option to go wireless was headphones' other big selling point. It's especially helpful in the car since it's one less thing to get tangled in. Battery life is long, rated at up to 16 hours with the ANC and 22 hours on Bluetooth only. The headphones charge with a standard microUSB cable, but if your kids forget to charge them, Puro includes a standard 3.5mm audio cable.
If you want to save some money, the company's BT2200 headphones skip the ANC but offer the same noise isolation and Bluetooth for $20 less. Price is probably going to be the biggest hiccup for most parents since the PuroQuiets cost $100, though they're currently on sale for $80. Given the features and audio and build quality, the price isn't unreasonable. They are essentially adult headphones but sized for kids and with the added benefit of a volume limiter.
