How about getting him a subscription to a podcast service, like Spotify or Apple Podcasts? Alternatively, you could get him a subscription to a particular podcast that he enjoys.
Another idea would be to get him a high-quality pair of noise-cancelling headphones so he can enjoy his podcasts without any external distractions. Or, you could create a custom playlist of his favorite podcast episodes and load them onto an MP3 player or USB drive so he can listen to them whenever he wants.
Lastly, you could consider getting him a book about podcasting, such as "Podcasting For Dummies" or "The Podcast Handbook", to help him learn more about the industry and maybe even start his own podcast if he's interested.
Or you can get him a star map with an important date you share.
