Disclaimer - I was given this pair of headphones in exchange for my fair and unbiased review.
The JLab JBuddies folding headphones answer many of the problems parents have with devices, headphones, and children. They're designed to be sturdy, with a single long cable that can connect to any phone, tablet, computer, or other audio device with a 3.5 inch headphone jack (or dongle, in the case of a few different models of smartphones. They're also, by design, unable to play audio at a volume level dangerous to young ears. They're comfortable, the audio quality is good, and they even have a small level of customization your child can do to them.
So for the good stuff -
The build quality is supurb. They're a thick but lightweight plastic that can stand up to abuse. The hinges for folding the headset are a little stiff, but seem very strong. The single-cable design helps cut down on the number of accidents that can happen when the cable gets yanked on (single-cable designs are usually much sturdier than split cable designs). The volume control mounted on the right can has a very solid feel to it.
The audio quality is pretty good, considering how quiet this headset is. I had to listen so I could get a feel for audio quality and volume level before I gave them to my son. While the volume limiter worked very well, it didn't cause issues with highs, mids, and lows. My playlist included the Jackson 5, Warren G, Anthrax, John Coltrane, and Mozart, all sourced from Apple Music, and all sounded as good as my pair of Sonys while played through the headphone jacks of my iPhone, iPad, and Onkyo TX-NR717 (using an Apple TV 3rd gen via HDMI with Apple Music via AirPlay as a source). Volume levels probably didn't exceed 82 decibels at my ears at any time, even with the Onkyo turned up completely. The headset was also nearly inaudible from 2 feet while attached to the iPhone and iPad at full volume; you could hear the Sonys from 8 feet away at that level.
Packaging was decent. the parcel was mishandled at sometime during shipment, causing box crush; however, it wasn't enough to damage the tray holding the headphones and sticker inserts. Had I seen these sitting on a store shelf, they definitely would have attracted my attention with the bright, colorful box.
My child found the headset comfortable over a period of 4 hours. He watched a couple of movies and two or three different things on YouTube. The headset was quiet enough where he could hear me over whatever he was listening to without taking it off. He did miss the higher sound output of my headphones, but not enough to take these off when I said no.
The retail price is definitely not bad. While you can buy your child cheaper headphones, they probably won't be built as well as these are, and will probably lack features like a volume control, single cable design, and the folding ear cups. They will probably also lack a volume limiter that works as well as this one does.
As for the bad, the only thing I was disappointed by is a lack of storage bag for the headphones. A few years back, I bought my niece the non-folding version of this headset from another electronics store as a gift. It came with a storage bag for the headset, where this one did not. It actually makes more sense for this set to come with the bag, since this pair folds and has a longer cable that could possibly become tangled.
All in all, it's a good headset. It's well-built and keeps maximum volume out of your children's devices low (along with your own when you hand them your phone). I can happily recommend these to anyone that needs headphones for their kids.
