RUIZU16GB MP3 Player with Bluetooth 5.3, 1.8" Screen Portable Music Player with FM Radio, Voice Recorder, 80H Audio Shuffle Playback, Lightweight for Sport Running, Expanded Up to 128GB Micro SD Card

Couple of things to note:-button commands can be a little funky--read the owner's manual-comes with cheap, virtually useless earphones-comes with charger-sound quality is fine on decent output hardware--little bass heavier than what i'm used to for default-does not work with iTunes and does not access the internet-file transfer easily done via computer click and drag, copy/cut and paste, or whatever. no need to install a third party software.-song names show up as file name instead of song title if they're different under properties if you're picky about that-does expand with micro sd as stated, though you may need to use a key or something to make sure the sd card goes in all the way and locks in place. kinda hurt my finger a bit trying before i resorted to the key.--on that note, files saved to the micro sd may show up on another external drive on your computer, and the files on it are not lumped together with the files on the device's main storage, but can be accessed through another menu selection. something to keep in mind if you want all your music in one place rather than split up!!-decent battery lifei have not tried using it for photo or video storage, and i wouldn't recommend it because the screen quality looks like an old flip phonei have not yet tried the radio either since i rarely use iti have not yet tried the voice recording so i can't say much for its quality eitheroverall, beyond my expectations for the price. my 16 gig ipod ran out of space for my music library since i follow a lot of artists on bandcamp and soundcloud and stuff so my library is always expanding--so i'm glad a 128gb micro sd goes in just fine. arrived quickly and in perfect condition.

I really want to like RUIZU X02 Music Player. It has a lot going for it.It seems well built and the buttons have a nice feel. In my opinion the user interface is fine and mostly intuitive although making it more aesthetically pleasing would be nice. Transferring music too it is pretty straightforward. Simply drag and drop or copy and paste. It works fine in Linux as well.Now I will get to the biggest issue for me. I never thought of myself as an Audio Snob, but the sound quality is just not up to what I am used to.To test I used the same flac, mp3, and ogg files on three different players; a Walkman from circa 2010 that in my opinion has great sound and a Sansa Clip+ and the Ruizu X02. The Walkman and the Clip+ both have nice clean sound in my opinion with the sound of the Walkman being the best.I've tried 4 different headphones 2 over the ear and 2 in the ear. In all cases the Ruizu X02 just sounds a bit "weak" to me and in all cases the Bass is just not rich enough , and it was hard to bring out all the sounds. There are equalizer presets and one custom slot. I've adjusted the EQ over and over to try to bring out some clean sound but can never seem to get it just right. At higher volumes it sounded more clear. On the other players the sound quality was the same at all volume levels.It is only a guess, but I am thinking the in the digital to analog conversion the sound quality is taken down. I'm hoping this can be remedied with a firmware update.Now, saying all that I still say this is a good device. I say that because the build, battery life and even the sound quality is good for the price. It is 1/3 the price I paid for the Walkman and it has an SD card slot so you can load tons of music on it. The Walkman does not have any expansion options.So the bottom line is that the Ruizu X02 likely acceptable for most listeners. If you are an audiophile you probably wouldn't be looking at a $30 audio player anyway but I'm pretty confident you won't be happy with this. Even though I give it 4 stars overall I may return it, but I'm going to test it for another week before I decide.

Nice little mp3, easy to use, pairs well with Bluetooth and good sound
