Children's headphones are often challenging to find a good fit for. In-ear buds are difficult to fit and even then the kids grow out of them so fast it isn't worth the expense.

You may find a decent pair of wireless headphones that work but for us we've found that these LilGadget wired headphones are the best overall for our little one.

With a 3.5mm jack they fit most airplane systems and combined with an adapter can interface with tablets and phones easily enough.
