in short: STAY AWAY FROM IT!
all in all this mp3 player is a waste of resources and the user’s time
(unless someone comes along and fixes the firmware X-D (but the playback problem could also be “in hardware”))
what is great about the player:
- massive amounts of internal storage 16GBytes for 20€ bucks!
- plus: Micro SD Card extension slot available
- mounts like an USB Stick, works with GNU Debian Linux 10
- has FM Radio
- button controls make more sense, after firmware upgrade (v1.1)
- design is okay
- case/housing is okay
- display is okay
- charges via default USB Micro-B 5x PIN (aka old Samsung Android SmartPhone power supplies)
why this player?
yes could user SmartPhone as mp3 player, but should not keep SmartPhone in pocket with LTE, Wifi and Bluetooth all turned on (not healthy)
so wanted something that has does not emit electromagnetic signals at all X-D (no antennas, no modems)
the problems:
the software on the RUIZU X02 (Made in China) has MANY bugs and flaws that render it almost unusable
- most problematic are errors in playback/decoding which produce disturbing noises “mp3 quierks”
- hear what those mp3 decoding errors sound click here
- hear what those mp3 decoding errors sound click here
- chokes on certain characters in “filenames[with-brackets]” to the extend, that the whole player firmware goes bonkers and stops working, which can only be fixed by reinstalling the buggy firmware firmware
- possible via terminal to copy on player, not possible via caja file manager -> it compalins “invalid filename”
- firmware restore only supported on windows 🙁 (Windows inside VirtualBox VM did NOT work (USB 1.1))
- the headphones that come with the player are cheap utter garbage
- can REALLY REALLY recommend the Panasonic BW Headphones RP-HJE125, they are ABSOLUTELY great in sound and durable
The MP3 player RUIZU X02 is of course a Chinese, provides with 16GByte internal memory (!!!) + Expansion possibility via MicroSD card enormous storage space, also the FM Radio works and even has an automatic transmitter search, but one of the most important functions of an MP3 player, to play clean MP3s without stuttering, this device unfortunately does not manage.
Unfortunately, the extremely annoying MP3 decoding error sounds again and again kill all the fun in music.
