Ruizu x02 digital music player review and tear down

This is a no nonsence great little stand alone music player that supports .mp3, .wav, .wmv, .ape and FLAC file formats.
Has an FM radio and voice recorder to boot.

This is a review _par_ _excellence_ ! It's not many that include a tear-down. It's a shame the battery didn't show its capacity. One thing you missed is how to carry it - it doesn't seem to have an attachment point for a lanyard. Does it have to be carried in the hand all the time?
I use an MP3 player all the time for listening to podcasts. Till now, I've used the Ruizu X06, which has been good, but prone to failure after about a year. Its battery capacity is 850mAh. I load up the unit in the morning, and it gives me 8-9 hours listening while in my workshop, cycling, shopping, etc. Sometimes, I download an audiobook, which can play for as much as 18 hours.
My last X06 failed last night, so I'm looking for a new one. This one seems promising.

still use mp3 player dont have to charge it every day like a phone and sounds better

[bigtom]

this looks perfect for me, my work doesn't allow phones or ipods/mp3 players, i wonder would this thing be able to pass through a metal detector?10 hours a day without music is just so wrong!!there's no reason why i shouldn't have some joy in work!

So someone just walked me through how to rip my cds into MP3 using Windows Media Player. I used to be so good @ this stuff.

I still have a ipod classic 2007 its.a 80GB the ipod classic was a awesome music player. The only thing it needs is a new hard drive so the songs won't skip

I became an Ipod collector, just cause so many people throw them out ! Started happening ..take a guess. yeah around 2008 with the roll out of the Iphone. Sometimes they are in perfect shape, sometimes a bit of screen crack, but all of them I have found boot up. Look around the bottoms of those recycling bins, and frequently in bags of wires and stuff like that.

29:32 I have one issue with the PCB layout around the TSOP Flash IC they have some unused pins and for some reason decided to remove the pads under them.

To make matters worse those pins are directly on top of other traces and vias. They're relying on the solder mask to prevent the pins from making electrical contact with shock and vibration (something anything portable will see) they could potentially scrub through the solder mask.

Hopefully those pins are not connected to anything inside the IC in which case it's still dodgy but ok. When I'm laying out PCBs if a pin on an IC won't be connected to anything I still leave the pad for mechanical support.

Nothing else stands out to me the layout looks fine otherwise.

Looks like a nice unit. About 12 years ago I bought a 4.3 inch media player that played everything. Had a really really nice clear screen which looked like HD, had really good DA converters etc etc. It had an FM radio I mean it was almost perfect.
It had 2 dead bright red pixels on the screen and I send it back to the ebay seller to be replaced. He refunded because it was the last one he had. Never saw one like it again and I was angry at myself that I had send it back. Seems like smartphones killed all these nice players

1:12 if my problem using phone to listen to my music is, it easily interrupted when I watching something like Instagram stories while listening to music. It is pretty annoying. So that's why I decided to have a stand alone mp3 player to play music.

Many of my young employees do not buy music anymore. They just listen to Pandora or another music streaming service. I still like to buy my music, but it's getting harder to find physical music now. I have transfered all my CDs to mp3, and I use a mp3 player at work.

That Battery is a 3.7 Volt Lithium Polymer 500mAh for MP3 MP4 GPS. Readily available - Probably also used in Bluetooth Headsets too.
Pretty neat gadget you got there - it would be interesting on how long the battery will last on a full charge?

[Bluethunderboom]

I had the Microsoft Zune MP3 Player, when I ttry to recharge the battery for the Zune, it doesn't want to charge like it suppose to, which tells me it might be dry as a bone to the point the battery may no longer hold the electric.

And I have the Nextbook Model NEXT2, I use for MP3 Content for like playing musics, or Mother Nature's sound. I use for to play one as Majestic Niagara Falls to block the annoyances, and to ease my stress when having a good nap or a sleep.

If there was ever an audio device needing re-configuring, this is it. Thanks, man.

Thanks Mr. Volt for this well done video review of the RUIZU X02 Ultra Slim Music Player. I have a very similar unit which is the Dansrue M01. The controls on my unit are touch spots on the face and I have to lock the unit to keep from hitting them when placing the unit in my pocket. A BIG PAIN! I like this Ruizu player a lot better and since the price here in the U.S. is only $25.99 I will be ordering one from Amazon today. I wish I had seen your wonderful video 2 months ago. Dear Friend keep the great content coming. My mind goes back to a video of ours that I watched where you were in a half underground box with a million wires going everywhere. That was fun! Thanks, Your Alabama Friend :-)

Great review. Just wondering as I just purchased it. Does the shuffle work well (had another one that the shuffle would restart at the beginning of the list when it was turned back on)?

[wd]

Have you reviewed any players, not Apple, that will play AAC files? I'm getting sick of Apple but I suppose I would have to convert all my AAC files to mp3 to use this player.

[rmjohnson]

How do I copy music to it? I am doing this for a friend and his music is mostly in folders, and a few on the root directory. He has 100GB of music, so it is going to take forever to copy this stuff. I just want to get it right the first time.

[shaun]

A headphone socket on it, first thing I was looking for .
I cannot go any lower than 360 compression in audio, I guss it will as these old phones do it in stereo .

[gmcnewlook]

I’ve worked in places I couldn’t bring a phone (one place fixed phones) but a mp3/ iPod was ok, I still use an older iPod when I work out, if something happens to it, no loss....

[fadialenezi]

I wish you can help me
1) can I change the sound speed? x1.5 or x2
2) can I start from the second 33 or 1.32 for example? or I should start from the beginning every time?!!
