OGG is a special music format. Onda VX818, an MP3 player, can play it. The sound quality of this music format is much better than that of MP3 player. Normally, the next album will cost tens of megabytes. However, if you find genuine OGG songs in this format, the next album will cost more than 7 megabytes or 8 megabytes. I suggest you get a format converter to play it.
