I recommend reading the best mp4 or mp5 in e-books

I love reading e-books on mp4. I recommend one.
It would be best if it had a function such as playing in the background and listening to songs while reading books.
Automatic bookmark can store multiple bookmark (more than 3)
Scroll the page quickly by sliding the button
Show progress percentage
display time
Can set font and background
I thought of these functions for the time being. I used to use the Meizu, and it felt really good. The sliding keys feel so good
Moreover, he could flip through the pages quickly and see the content at the back. It was very good for reading novels that he had already read.
Not too expensive!
You'd better give me a link so that I can take a good look first. It's too troublesome to find it.

The best MP4s or MP5s for e-books were usually tablets or smart phones because they had powerful e-book reading functions such as built-in reading lights, expansive storage, and support for multiple e-book format. However, if you need a device specifically for reading e-books, some MP4s or MP5s are also good choices.

Some MP4 or MP5 devices also provide additional reading functions such as reading aloud, annotation, bookmark, etc. These functions can provide a better reading experience. The choice of equipment depended on the specific needs and budget.
