"I don't need anything" is the sentence every gift-giver dreads, mostly because it's rarely true and never useful. The trick isn't to take it literally — it's to find something that sidesteps the question of "need" entirely.
Give him something that isn't about utility at all
At Galaxiana, naming a star and writing him a message removes "do you need this" from the equation completely — it was never meant to be useful, only meaningful. From $34.99, and noticeably harder to predict than another gadget.
Pay attention to what he actually does, not what "men" supposedly like
Generic "gifts for him" lists tend to assume every man likes grilling, sport, and tools. Some do. Plenty don't. Whatever he genuinely spends his free time on — reading, cooking, building, running, collecting odd things — that's where a thoughtful gift actually starts.
Book the thing he won't book for himself
A lot of men are remarkably bad at treating themselves. The class he keeps mentioning, the match he's never gotten around to, the night out with people he hasn't seen in years — book it, and remove the last excuse.
Say the thing out loud
Many men hear far less direct appreciation than they give. A short, specific note about what you actually admire in him tends to land harder than anything wrapped in paper — mostly because it so rarely happens.
