How about a subscription to a popular podcast service like Spotify, where he can access his favorite podcasts ad-free and listen to exclusive content? Or perhaps a high-quality pair of noise-canceling headphones so he can enjoy his podcasts without any distractions. Another option could be a book by his favorite podcast host, such as "Can't Hurt Me" by David Goggins or "Atomic Habits" by James Clear, which give him an opportunity to dive deeper into topics that pique his interest.
Or you can get him a star map with an important date you share.
