Hmm, interesting question. I mostly use streaming services, so my offline experience is limited to downloads within those apps. I hadn't considered managing my own files. Makes me wonder if I have any old audiobooks on my computer I could put on my phone...

Final thought (not really final, just another comment): Remember that 'large' is relative. What's large for one phone (200 books) is small for another (2000 books). Mention your actual approximate size when asking for advice. An app that works great for 500 might choke on 5000. For truly colossal libraries (10,000+), the only safe bet is a server-client model like Audiobookshelf, where the phone is just a thin client. For most people, 'Smart' or 'Voice' will handle up to a few thousand local files without issue on modern hardware.

For those with a Plex Media Server already running: the PlexAmp app! It's primarily for music, but if you add your audiobooks to your Plex music library (organized properly with metadata), PlexAmp can play them.
And the killer feature is 'Plex Dash' or now built-in tracking—your play progress syncs across any device running PlexAmp because it's all tracked by the Plex server. You need a Plex Pass for PlexAmp, so it's not free, but if you already have a Plex server and a Plex Pass for other reasons, this is a seamless solution. The interface is gorgeous, and the sonic analysis features are cool bonuses.

The volume boost feature in some apps is a lifesaver for older recordings or quiet narrators. It's not just about making it louder, but about normalizing the audio so you don't get blasted by sudden loud music in the intro. See which apps offer that in their free tier.

For audiobooks with PDF companions (like textbooks), tight integration is key. None of the Android players do this perfectly. However, 'Smart Audiobook Player' allows you to open a linked PDF from within the app when you're at a bookmark. It's a manual link, but you can set it up. When I hit my bookmark, I tap to open the corresponding diagram or chart. It's a clunky but functional bridge between audio and text that I haven't seen elsewhere.

This might be a hot take, but the search for the perfect free app is a distraction. Your time has value. If you listen to more than two audiobooks a month, a subscription service like Scribd or Audible Plus is worth it for the sheer convenience and peace of mind. The 'free' path often costs more in time and mental energy.

Don't overlook 'Libby' by OverDrive if you get audiobooks from your library! It's not a general file player, but for library loans, it has both a sleep timer and variable speed control built right in. The timer can be set in minute increments or by chapter end. Speed goes in increments from 0.6x to 3x. The best part is it's completely free with no ads, since it's tied to your library card. Obviously, it only plays books you borrow, but for that purpose, it's fantastic and often forgotten in these conversations.

The 'weight' of the app matters. Some apps are over 50MB because they bundle libraries for streaming, ads, and analytics. For a purely offline experience, I want something lean. 'Voice Audiobook Player' is around 15MB. It's snappy and doesn't hog resources.
On a phone with limited storage or an older processor, this makes a noticeable difference. The app should feel like a lightweight player, not a bloated platform. This minimalist approach often correlates with stability and a focus on core functionality.

Has anyone mentioned Voice yet? Because Voice is the answer. The speed slider goes from 0.5x to 3.0x, and it's buttery smooth. What I love is that you can set a one-tap button to your favorite speed—mine's 1.7x for most narrators.
It also supports OPDS for getting books from online catalogs, which is a nice bonus if you use certain... unofficial libraries. The developer is active, and the app just keeps getting better.

I bounced between apps for months. Voice, Smart, Listen... they all have merits. But for Bluetooth, the consistency winner for me turned out to be 'Just Another Audiobook Player.' Yeah, that's its real name. It's on F-Droid and GitHub. It's super lightweight, and because it's simple, there's less to go wrong with the Bluetooth stack.
I had weird delays with other players where I'd press 'next' and it would take a second. This one is instantaneous. It's not as polished visually, and the library browsing is basic, but if the primary interface for your listening is your Bluetooth controls, not the phone screen, then this app's simplicity becomes its greatest strength. Highly recommend for the tech-savvy who want control.
