Kids Headphones with a USB connection? Is this possible?

[supersun23]

We have bought a 2nd hand Yamaha keyboard. Unfortunately the port for standard headphones does not work (the headphones work on other items). I have noticed it has a USB cable port. Are there kid's headphones around that connect via USB?
TIA

Although it’s possible to get usb headphones (will confess to knowing nothing about these) I’m guessing it’ll be unlikely to work in this situation.
The usb connection on most keyboards will be for controlling the keyboard from a computer or other device (like you would with midi, a control protocol) and will not contain any audio or sound.

Must stress this is only an educated guess, but I’d be surprised if it would work.

Thank you, I think you're right
