Jr310BT

Not sure if you can get them where you are, but we've got the JBL JR310BT headphones. I've seen my son stretch them apart, and dropped it multiple times. Still works fine! It's also not too loud, but good enough for the airplane. It's also not too expensive, and you can get either the bluetooth version or the wired version. We got the bluetooth cause we don't really like the idea of wires dangling around our kids. Comes with stickers, so your kid can go crazy with that on the headphones. Edit: Just checked the JBL website, and it's $49.95

We like the JBL kids headphones. Wireless is required with our kiddo (2.5)since he would just have fun wrapping the wire around his neck 🤦‍♀️

We've had JBL headphones for kids that have held up really well, our third kid is now using them.
