You might be able to tell by my username which is my favorite audio drama. If you haven't heard of it, Wolf 359 is a space opera dramedy focused on a cast of deeply likable characters who find themselves carrying out mysterious research onboard a space station owned by a soulless corporation. Heads up, the whole thing is very enjoyable but the creators say the real story doesn't get going for real until about episode 9 and I would agree. It's funny and entertaining but gets pretty serious around there. Don't worry, the early episodes are super short and still good.

Other audio dramas I highly recommend are:

Bronzetown
1865
Limetown
Edict Zero FIS
Station 151
Archive 81
The Magnus Archives
Theater of Tomorrow
The Hyacinth Disaster
Life After / The Message

Here are a few of my favorite examples:

1. "Long had he believed that a gentleman should turn to a mirror with a sense of distrust. For rather than being tools of self-discovery, mirrors tended to be tools of self-deceit." p. 36

2. "For if a room that exists under the governance, authority, and intent of others seems smaller than it is, then a room that exists in secret can, regardless of its dimensions, seem as vast as one cares to imagine." p. 64

3. "After all, what can a first impression tell us about someone we've just met for a minute in the lobby of a hotel? For that matter, what can a first impression tell us about anyone? Why, no more than a chord can tell us about Beethoven, or a brushstroke about Botticelli. By their very nature, human beings are so capricious, so complex, so delightfully contradictory, that they deserve not only our consideration, but our reconsideration - and our unwavering determination to withhold opinion until we have engaged with them in every possible setting at every possible hour." pg. 120-121
