What should I get?

I received a $300 gift card. I have no idea what I should get. I have an iPad and a kindle. I am thinking about some headphones like the really nice pairs that go over your ears. Does anyone have a recommendation on a good pair? Or should I get something else? I’m blessed today I don’t NEED anything. Whatever I purchase will be a nice gift to myself not a necessity. Would love to hear from you!
