KIDdesigns - Frozen II Bluetooth Headphones - Blue

If the laptop has bluetooth yes they do. My kid uses it for the online classes everyday.

They fit my 3 year old but he’s also 99th percentile for head circumference

There could be several causes including internal connection and battery issues. Longshot but, used compressed air to clean out the inside of the connector on the headphones. Sometimes dust or lint can prevent a good connection. Also, if possible try out another charger/cord combination. Failing that, see if you can return the item for exchange.

We returned the pair we purchased. I was unable to keep a charge for more than a few hours. Bluetooth constantly dropped its connection from every device I tried. I could not find a way to simply turn them off in order to preserve the battery whenever we were not using them. Not a good product in my opinion.

No reason they shouldn't.
