Very clear and top notch sounding music from the player. Feels heavy for its size. Easy to upload music onto the microsd card it comes with, and easy to make a custom playlist. Easy to go through the menu, everything looks to be built sturdy. Looks very nice. It's a bit pricy for an mp3 player these days but this won't have any harmful electronical waves with good audio quality.

Please Note that I purchased my MECHEN M30 in September 2023. There may have been some subtle changes to its firmware since then.PROS:*Feels solid.*Easy to operate with slight learning curve. *Beyond 20 hours of continuous use on a single charge.*Excellent sound quality with balanced tonality from bottom to top.CONS:*No gapless playback.*Will likely not play audio files in desired sequence.Out of the box, my unit would not play audio files in the correct sequence. Fortunately, a firmware update is available from the MECHEN website that corrects this. Its firmware updates are simple and easy to install. The first update includes the following:“Song sorting rules changed to follow music file title instead of ID3 informationFast forward and rewind, play and pause, volume +- are now all available in the lock screen except the button Menu and Return.”I’m waiting for a firmware update to add gapless playback. Until then, the player gets 3 out of 5 stars from me.*UPDATE 02/02/2025*I wrote a letter to MECHEN inquiring about my concerns with the M30, and received the following reply:“Hello.First of all, thank you for your support and trust.For the three points you mentioned to answer the question, may not make you satisfied.1. You mentioned gapless playback, the player can not do this, all single-core players on the market are so.This kind of function involves the setting function of the music APP whether or not with this kind of option, generally speaking Android system player should be able to, I think it can, because it supports the download APP, go to download the APP that can be with seamless playback function can go to realize it.For now, this type of player is not supported.2. Character truncation problem, the player is determined by the system, according to the pixel points and how many speed reduction to decide, to reach a certain threshold will be truncated or do not show the whole character, some characters are a little wider, but not enough to show the whole character, there will be a whole character does not show the situation.For example: the last one is the M character, but the principle can only be put in half, can not be divided into two halves of the M, then the M is directly not displayed, probably this is the meaning. The software has a certain que value. Not that the first line cut 20, the second line cut 19, did not do this judgment.How to make good use of the song names and sorting, I upload the user guide of the product for you in the attachment, in which you can find the method of how to sort the songs, so that it is easier to organize your songs and arrange the order.3. Regarding the empty folder “System Volume Informati”, it is a folder that is automatically generated after connecting to the computer, you can't see it on the computer, but you can see it in the player, and you can't delete it on your own, it's a system-generated file, you can get an explanation of it by putting the name of the file on the web. You can get their explanation.Thank you for your patience and understanding.Best regards.”As for gapless playback, there is a workaround. Using audio editing software, combine the files to make one file. The only drawback to this is that songs within the file cannot be individually selected. But, if you typically listen to albums in their entirety, this should not be much of an issue.

This is a very fine non-bluetooth or wi-fi music player that is hampered by non-intuitive navigation menu commands. I had hoped that I would become accustomed to its quirky navigation but it seems like I struggle with it everytime it gets used. In my opinion, improvements in the user experience would make this an otherwise great music player.

This was exactly what I wanted for my bedroom. Awesome sound quality and controls I can easily find in the dark. If I can't sleep this is what gets me relaxed without disturbing my wife. Love the precise mechanical controls, especially the wheel that navigates through the queue or adjusts the volume, and no touch screen to accidentally activate. Built like a tank and worth every penny. If you want a light thing to run with this isn't it, but for me it's perfectly designed

Using this little player is just like old times, kind of. Like it doesn’t support Bluetooth headphones, that’s old school. But it’s also for a pretty good reason. This player is meant to play high fidelity audio files and supports a wide variety of lossless formats to accomplish that feat. Using a Bluetooth headset to listen to lossless audio is like putting premium gasoline in a 1973 AMC Gremlin.If you’re an audiophile you’ve probably already figured out that I don’t know what I’m talking about. If by some stroke of dumb luck, I’ve managed to sound knowledgeable so far, let me put that mistake to bed right now. I don’t know anything about audiophile stuff. I don’t know the codecs, I don’t know about frequency response or sample rates or drivers or bit rate or any of that stuff. What I DO have is a really nice set of in-ear monitors I won in an online drawing 22 years ago or so. In 2025 money this won’t sound as crazy as it did in 2003 but these were top of the line, custom fit (I had to go to an audiologist and have molds made of my ear canals), monitors by Ultimate Ears (they were fairly niche “musician only” back then) that sold for around $1000. They are UE-10s and were so high-end they stamped my initials in each earpiece when they made them and came in a little aluminum brief case that had my name engraved on it. These may not be the best or even close to the best in the audiophile world, but they were and still are the best headphones I’ve ever used. It’s not even really close when compared to anything else I’ve ever tried. The first time I ever used them I was SHOCKED by the detail I had been missing in my favorite CDs. I heard things I had never heard before in songs I had been listening to my whole life. The subtle intake of a breath before singing, the zip of rough fingertips on acoustic guitar strings, the ticking of a shirt button tapping the back of a guitar as the neck of the guitar creaks and the player prepares to strum the first chords, muffled voices in the background, subtle instrumentation added for texture, the wet smacking sound of someone opening their mouth to sing. It was like being in the room while the song was being recorded. It changed the way I listened to music…until the iPod came out and I ripped all of my CDs to MP3 and killed most of the magic. In the 20 years since, I’ve stopped using the UE-10s in favor of tiny Bluetooth earbuds that fit in my pocket. The iPhone doesn’t even have a headphone jack anymore. So I’ve gotten used to muddy audio.It was with real excitement that I ripped one of the greatest sonic recordings ever (Dark Side of the Moon) put the files on this player (drag and drop onto SD card) and plugged in my old UE-10s. From the first quiet heartbeats through Great Gig in the Sky I was stunned by how much fuller the music was compared to the streaming versions on Apple Music or the MP3 files on my 18 year old iPod that somehow still works. The sound quality is phenomenal.The software on the player is pretty utilitarian and the scroll wheel is kind of in an awkward spot and it doesn’t come with nearly enough storage considering the uncompressed files it will be holding. The battery seems to be good and the build quality is excellent. It feels like a real piece of equipment. Again, I’m no audiophile, but in my opinion this player is great.
