Materials to help my Special Needs Child Learn Easier

My child has autism and we’re in desperate need of technology that will keep him focused and will also last him for a long time down the road. The earbuds have noise cancellation. This will slow him to block out distractions and I heard they will last for a long time. The laptop will last him for years so we won’t have to worry about not having a laptop for a long time. Any help is appreciated. Thank you.
