What should I get my boyfriend for his birthday (Oct. 28th?)

My boyfriend is turning 15 on Oct. 28th and I don’t know what to do or get him. He likes listening to music, playing games on his phone, skateboarding, drawing graffiti art (on paper, not walls) and those little Candy Corn Pumpkins. He’s deaf in one ear and is a ambidexterity (both handed.) This is my first boyfriend and I don’t want to mess this up. Please answer before the 28th, thank you.
