Audiobooks let you enjoy stories while you're busy. But Android users with M4B files face two main problems. Some files have DRM protection, especially those from iTunes. This locks them to Apple devices. Other times, your Android player can't handle M4B files properly and unable to detect the chapters and bookmarks.
Don't worry. This common issue has clear solutions. Whether your M4B files are protected or not, this guide will show you how to play M4B files and audiobooks perfectly on your Android phone or tablet.
Part 1. Can Android Play M4B Files?
The simple answer is yes, Android can play M4B files, but there's a big catch.
M4B is better than MP3 for audiobooks. It saves chapters and remembers your listening spot. But M4B files come in two main types. Knowing the difference is key to playing them on your Android device.

Type 1: DRM-Protected M4B (Locked Files)
These files usually come from stores like iTunes. They have a digital lock called DRM (Digital Rights Management). This lock stops the file from playing on any device or app not authorized by Apple.
If you transfer a DRM-protected M4B to your Android phone, your music player or even a dedicated audiobook app will likely refuse to open it.
Type 2: DRM-Free M4B (Open Files)
These files are unprotected. They may come from public domain sites, independent sellers, or ones you made yourself. But your phone's standard music app usually can't read chapters or remember your spot. You often need a specialized M4B player app to open them.
To wrap up, you can't just drop any M4B file onto Android and expect it to work perfectly. You need the right app for unprotected files, and a conversion tool for protected ones.
Part 2. How to Play M4B on Android (For DRM-Free Files)
DRM-free M4B files are easy to handle. You just need the right tool. There are two simple ways to play them on your Android device. You can use a dedicated M4B player app or rename the file to make it compatible with your regular player. Let's look at both methods.
2.1 Use the Best M4B Player for Android
The simplest way to play an M4B file that is not DRM-protected is to use an Android app specifically designed for audiobooks that includes M4B support. Unlike standard music players, these apps are built with audiobook features like bookmarking, variable speed control, and sleep timers.
Here are some of the most popular and highly-rated M4B-compatible Android audiobook players:
App Name | Key Features | M4B Support | Note |
---|---|---|---|
Smart AudioBook Player | Automatic pause on sleep, adjustable playback speed, history, cover art download. | Yes (including chapter support) | Highly recommended, with a full-featured free 30-day trial. |
Listen Audiobook Player | Folder-based library, variable speed, sleep timer, automatic rewind. | Yes (for DRM-free files) | A paid app, but well-regarded for its robust features and reliable playback. |
Sirin Audiobook Player | Supports a wide range of formats, including M4B; built-in torrent client. | Yes (including full chapter support) | Good all-rounder with extensive format support. |
VLC Media Player | Versatile media player that supports almost any format. | Yes | A good universal option, though it may lack some dedicated audiobook features like specific bookmarking or series management. |
Using these apps is simple. Let's take Smart AudioBook Player for Android as an example.
- Move your DRM-free M4B files from your computer to a folder on your Android device.
- Open Google Play Store and download Smart AudioBook Player.
- Go to the Library screen.
- Tap the three-dot icon in the top right to open Settings.
- Select Root folder.
- Find and choose the folder with your M4B audiobooks.
- Tap the circular arrow icon in the top right to refresh your library.
- Your M4B files will appear in the Library.
- Tap a file to start playing it.
- The app will save your listening position automatically.
- To jump to a chapter, long-press the Next file button to open the chapter list.
2.2 Play M4B via File Renaming
If you do not want to download a new app, or if you just want to quickly test a file, you can try this simple trick. This works because the M4B format is technically very similar to the standard audio format, M4A. Android devices often support M4A better than M4B.
The Trick and Its Risk
- The Trick: Change the file extension from .m4b to .m4a. This makes your phone think it's playing a normal M4A audio file.
- The Risk: Your phone will treat the audiobook like a regular song. It won't remember where you stopped or save chapter data. You could lose your place in the book.
How to Rename M4B Files to M4A on Android:
- Open your File Manager app.
- Find the folder with your M4B audiobook.
- Tap and hold the file name, then select Rename.
- Change
.m4b
to.m4a
. - Save the new name.
- Open the file with your default music or media player. It should start playing right away.

Part 3. How to Listen to M4B on Android (For DRM-Protected Files)
If your M4B files come from iTunes or have DRM protection, the methods above won't work. Don't worry. The two solutions below will help you fix that.
3.1 Convert M4B to MP3
MP3 works everywhere. It's the most compatible format for Android and almost any device. If your M4B file has DRM protection, converting it to MP3 is the easiest way to play it freely. Once converted, you can listen to your audiobook on any Android player without limits.
But conversion isn't that easy. Most online M4B to MP3 converters and free tools like VLC can't handle DRM-protected files. In most cases, you need a special tool to remove the DRM lock. Want to explore your options? Check out this full guide.
