Question about Joliker MP3 player

The Joliker MP3 player is also known as the Jolike M4 (MP3 player). This is the same model (https://www.jolike.com.cn/cpzx).
I do not know why the player is called Joliker at digitec.
The player, how could it be otherwise, comes from China. However, it is a very sturdily built device and fulfils its purpose perfectly. It is definitely worth its price.

It's the Joliker MP3 player that comes in handy on long-haul trips...
