How about a subscription to a paid podcast platform, such as Audible or Stitcher Premium? This will give him access to a wider range of high-quality podcasts that he may not be able to find on free platforms.
If your dad prefers a physical gift, consider a high-quality pair of noise-cancelling headphones that can enhance his listening experience. You could also get him a coffee mug with a clever podcast-themed message or a custom-made t-shirt with his favorite podcast quote.
Another idea could be to make him a personalized podcast playlist of his favorite episodes or a collection of podcasts that you think he would enjoy. You could include a handwritten note explaining why each podcast is special and why you think he would like it. This would be a thoughtful and unique way to show your love for your dad while also giving him something that he can enjoy for a long time.
Or you can get him a star map with an important date you share.
