— From Reddit
If you've ever wanted to enjoy your favorite Audible audiobooks while driving or on the go, storing them on a USB flash drive is a great way to make them portable. However, the process isn't just transferring the audio files to USB due to Audible's DRM protection. In this guide, we'll show you the best way to put Audible books on USB drive and play them across various devices, from your car's audio system to your MP3 player.

Part 1. Can I Save Audible Books to USB
Yes, you can transfer Audible books to USB and other external hard drives, but the audiobooks you download from Audible are usually in AA or AAX formats, which are restricted to Audible apps or compatible devices. Though directly copying and pasting the files from USB won't allow playback on other devices, there are alternatives to help you get these Audible books on a USB. You'll need to convert them to a more accessible format first with the Audible converter tool.

Put Audible Audiobook to USB
With the DRmare Audible Converter, we had got the Audible audiobooks to computer. Here let's see how to copy Audible book to USB drive for listening on other devices.
Step 1. Plug your USB flash drive into an available USB port on your PC or Mac. Wait a few moments for the operating system to initialize the hardware and mount the drive.
- On Windows: A notification may pop up; otherwise, open "This PC" or "File Explorer" where your drive will be listed under "Devices and drives" with its assigned drive letter.

- On Mac: The drive icon should automatically appear on your Desktop. Alternatively, you can find it in any Finder window sidebar under the "Locations" category.
Step 2. Open the folder where DRmare saved your audiobooks. It's recommended to organize your files into folders by Book Title or Author at this stage.
Step 3. Once your files are organized, you can transfer them from your local storage to the external drive using the native methods for your system.
- On Windows: Highlight the audiobook files or folders, right-click on the selection, and hover over "Send to". From the sub-menu, choose your USB Drive as the destination to begin the copying process.
- On Mac: Open your USB drive in a separate Finder window. Simply select the folders from your computer and drag and drop them directly into the USB window to initiate the transfer.

Step 4. Always eject the drive software-side before physical removal to prevent file corruption. Once unplugged, connect the USB to your car or media player to start listening.
What if the USB won't play?
If your device doesn't recognize the files you just copied, it's likely a File System issue. Most hardware requires a specific format to "see" the data. If your USB is currently formatted as NTFS (Win) or APFS (Mac), you may need to reformat it. But don't forget to back up your important files first, since formatting will permanently erase all existing data on the USB.

Get Audible Books from USB in the Car
The ultimate way to enjoy Audible in the car is via a USB drive, which provides a stable and high-quality connection. Whether on a long road trip or a daily commute, you can enjoy audiobooks without relying on glitchy Bluetooth or internet issues.
Step 1. Insert your USB flash drive into the car's USB media port.
Step 2. Use your car's dashboard controls or steering wheel buttons to navigate to "Media" or "USB Source". Then locate your organized folders to find the Audible book you want and enjoy it.

Connect a USB with Audible books to the TV
Most modern Smart TVs and streaming boxes now act as high-quality audio hubs. If you want to play Audible on Samsung TV, LG, or Sony models, using a USB drive is a reliable way to bypass app compatibility issues. And you'll find that Smart TVs are excellent audiobook players for a truly immersive narration experience.
Step 1. Locate the USB service port on the back or side panel of your Smart TV and firmly insert your drive.
Step 2. Grab your TV remote and navigate to the "Source" or "Media Player" app. Your TV should automatically detect the USB drive as a new storage device.
Step 3. Browse through your organized folders, select the MP3 or M4B book files, and press "Play". With your TV's soundbar or home theater system, you can enjoy a theater-like audiobook experience at home.

Part 4. FAQs about Audible Books on USB
Will converting Audible audiobooks to MP3 affect the narration quality?
No. While MP3 is technically a "lossy" format, the actual impact on narration quality is virtually undetectable if handled correctly. Using a professional tool like DRmare Audible Converter allows you to select the "Lossless" output mode, which strips the DRM protection while keeping the original audio stream intact.
Why isn't my USB drive displaying Audible audiobooks in my car?
It can be caused by the file format or the drive system. Most car stereos cannot read encrypted AAX files, and they require universal formats like MP3. Additionally, many car head units only recognize USB drives formatted as FAT32. If your drive is formatted as NTFS or APFS, or if the files are still DRM-protected, the car will fail to play your audiobooks.
Can I permanently keep Audible audiobooks after downloading them?
Yes. Any audiobooks you purchase can keep forever, even if you cancel your Audible subscription. However, you will lose access to titles from the Plus Catalog without an Audible membership. To ensure true permanent ownership and offline freedom, you can back up your purchased library to a USB drive using the DRmare Audible Converter.
