A great gift idea for your wife who loves podcasts would be to create a personalized and romantic podcast episode just for her, where you can reminisce about your relationship journey, share some of the experiences you've had together, and express your love and appreciation for her. You can use online tools like Anchor or Buzzsprout to record and edit the podcast, and then share the final product with your wife through a platform like Spotify or SoundCloud. You can also consider getting her a subscription to a podcast platform like Audible or Stitcher so she can access a wide range of podcasts on different topics that interest her. Another option would be to get her some high-quality headphones so that she can enjoy her podcasts wherever she goes.
Or you can get her a star map with the date of your anniversary.
