How to do it?

We open a book or a notebook with notes, plug in the microphone and record the text read aloud. It is best to divide the text into multiple parts, each creating a separate file. Then we make one more recording, which will be a kind of table of contents, for example 1- mitosis, 2- mitochondria, etc. We save all files as .mp3 and copy them to the player.
Glue the headphones in the corner, in the upper inner part of the sweatshirt. We make a small hole in the pocket of the sweatshirt, through which we insert the headphone cable and connect it to the player. We configure the volume and cheat.
The earpiece can be inserted directly into the ear, then the sound is clearer, but this solution works mainly for people with longer hair. With this option, we recommend using wireless headphones (e.g. bluetooth).
