I only had one criteria when buying these headphones - to find something that will last more than a couple of weeks when used and abused by my kids. We've been through several small headphones, and in the interest of being lightweight and foldable they all have a dainty build that just doesn't hold up. These are different - they don't fold, they don't have moving parts, and they work! They also definitely produce a lower volume than other small headphones, but still sufficiently loud for games and movies. Never thought about buying headphones that limit volume, but now that I have them I think it's a good feature. I came across some reviews of other "safe" kids headphones that mentioned cost as a major concern, which is amazing to me. If anything, 20, 30, even 50 bucks is not a big price to pay for healthier ears. If the headphones last even half a year, I'll consider it money well spent, but it seems like they'll last much longer. As for cons, the only one I can think of is that these are definitely sized for kids - the other small headphones we've had I could still use, but these are a little tight. Hope this helps!
