I had ordered it from China but not until being offered on Amazon was I able to obtain one. I have an entire collection of DAPs (digital audio players). I started a collection as a hobby in 2016 and ended it here, with this unit. I have a great collection of players and am content to end collecting them. I really want to be able to enjoy them and I also want to live a long life. Since the batteries cannot be changed in any of my players, if I really like a unit, I will buy more than one unit to serve as a replacement.My first impression of the AP-80 was neutral. Mine came with a gray silicone case. Perfect. The most recent players are so much better than the ones from just one year ago. It's a conspiracy, but the last iteration of players totally and completely meet my musical needs and with this model, and the Shanling M5s, I am done collecting these beautiful, amazingly fine sounding music players.This player falls somewhere in between the Shanling M0 and the HyBy R3. I am so impressed with all 3 of these players. Each one serves a specific function. The Hidizs AP-80 excels in its hi-end. It has absolutely ridiculously crystal clear high-frequency audio. The AP-80 uses the same operating system as the HyBy R3, including its MSEB sound tuning system. The system is more dynamic on the R3 and the R3 has a more musical platform, for example, its MSEB sound tuning system will distort much easier than the one on the AP-80.The AP-80, however, is capable of tuning its MSEB sound to almost any position without “popping”/distorting on certain passages. It excels in my computer room, where I have it wired into a European model Pioneer SX-757, which is a 1990s era 100 WPC RMS @ 8 ohm receiver and a pair of JBL Studio L Series 820 bookshelf speakers that were specifically made for the AP-80, or so it seems. These speakers have two tweeters, one 3/4” mylar-dome ultra-high frequency driver, one, one inch pure titanium high frequency transducer, 4” mid and 6” woofer (neighbors!). These speakers were made specifically for high resolution music.This player, the Hidizs (I am learning how to spell the name, it is a tricky one to learn!) AP-80 sparkles when I turn the amp on. I truly enjoy listening to the AP-80 and make excuses to go into the computer room and listen. I have to mention (burying it here) that when I turn the external power amp on and turn the volume up to 10'o'clock, even less, there exists an audible radio frequency pitch coming from the screen. It's not loud enough to interfere with my enjoyment of the AP-80, not noticeable when listening to music. It has something to do with the power. It only makes the noise when plugged into a/c power. It does not make the noise when running off of the battery. Increasing/ decreasing the Brightness changes the pitch. Non-the-less, filtering the noise should be taken for granted in a high-resolution player, and none of my other many players show signs of the screen causing audible noise in the audio when running off a/c. I ordered a second AP-80 and that is how I figured out it was coming from the power.The menu works quite well. It has an adjustment called “Soundfield” that does not exist on the most updated version of software on the HyBy R3, and that's where Hidizs got the operating system. I have the “Soundfield” adjustment turned all the way up too. It makes a big difference.The AP-80 is about the same size as the Shanling M1, but much more solid. There are a lot of new model DAPs out right now. The fact that I have incorporated this player into my everyday listening means I like it a lot because I have many different players to choose from. The AP-80 has the clearest, most crystal clear treble of any player I have listened to and its overall sound can be adjusted in literally thousands of different configurations. Its sound tuning system is very forgiving, allowing the listener to adjust the sound to some almost ridiculous results without distorting.When I find my camera, if they let me, I'll show the AP-80, M0 and R3 side-by-side. I can't find my camera.The AP-80 is a 100% solid contender in the DAP market and should be considered by anyone looking to purchase a fun, great sounding player at a reasonable price.

I bought the Hidizs AP80 and a XDUOO X3II player last year. My trusty Sandisk Sansa Clip and Fuse players don't have hi-res screens for album art. Both of these newer players have larger color screens that better show album artwork. Because I purchased the AP80, I eventually received a forwarded question about the Hidizs capacity for files. The customer wanted to know if the player would handle the music files from 3000 CDs. I answered NO, but there is more to the story. I thought I would post my answer in the form of a review with a photo of the Hidizs nearing its maximum index of 20000 songs.3000 CD's worth of songs? I'll assume 12 uncompressed songs per commercial CD. I don't think that this player will handle 36000 songs in its database selection modes (All, Albums, Genres, Artists). But the Hidizs does work with larger numbers of files when in Files mode. In Files mode, you navigate the SD card manually. If you navigate to an M3U playlist, the Hidizs does play the playlist in unsorted or random order.I sometimes use the AP80, but I prefer the XDUOO X3II as my daily driver. Because of the XDUOO lower 15000 limit, I have a little under 15000 songs on a 256GB module. My memory card is about half full and the HIdizs takes about 10 minutes to update the database if I make changes. The Hidizs AP80 displays all of the songs OK from the All mode icon, and they are alphabeticaly listed. Navigation in this mode is cumbersome at best. There is a alphabet bar with tiny letters on the right side of the screen that allows you to jump back and forth between letters, but from there, you'll be slapping the screen to navigate up and down within a given letter.Genre is no better for me, because I only listen to a few genres. When I select a bigger genre with say thousands of songs, the Hidizs AP80 completely halts for five or more minutes then it will display the large list of songs in that Genre. This list does not have an alphabit bar on the right, so get ready for some screen slapping. What is worse and completely unacceptable in the Genre mode is that even after freshly updating the database, when I select a song, an entirely different song from the genre plays.Because of the unsatisfactory Genre mode behavior, I usually manually navigate the folders on the memory card where I have files organized in 22 alphabet groups, then by artist, then by album. In this mode, I have not discovered a player limit to the number of songs, but I don't fill up the memory card because I still like using Artist mode which does not seem to suffer from the Genre mode dementia.I also use relative M3U playlists that I have created with various programs. Although the Hidizs will play an M3U playlist from any directory in File mode, I store these in the playlist directory that gets created when a new playlist is manually created and saved right on the Hidizs. The name of the folder on the memory card where playlists are stored is playlist_data. Playlists created offline and placed in this directory do appear with a thumbnail when the Playlist option from the menu is selected from the Hidizs Favorites menu. These same playlists can be selected by navigating to playlist_data directory in file mode. Small playlists work as expected. Large playlists of 5000+ songs can take several minutes to load the first time. After that first load, subsequent loads are snappy even after rebooting the player. Even these large playlists play each song correctly which saved me from throwing this player in the trash given how it works with genres. My largest playlist is 5500 songs, and the Hidizs will show for instance 2187/5500 when it plays Good Vibrations by the Beach Boys.As an experiment for the Hidizs, I added more songs from my library to the memory card for a total of almost 32000 songs. The Hidizs can see them all in file mode, and as I mentioned can play them from a playlist too. When I go look in Album mode, though, only some of the new albums are listed. I could find the newly added album Crooked Line by Nils Lofgren if I navigated to it in Files mode, but it was nowhere to be found in Album mode after performing a database update wherein the Hidizs quits updating as soon as it gets to 20000 files. All of the songs from that Lofgren album were also missing in the All Songs mode and Nils was missing from the Artist list too. I think the newer Sony Walkmans have a similar 20000 file limit. The XDUOO reportedly does 30000 with a firmware update but my virgin XDUOO X3ii pegs at 15000. I prefer to use the XDUOO because it has two additional buttons (not a touch-screen player).Bottom line: Will the Hidizs handle 30000+ songs? It depends on your definition of "handle".

This is a strange and amazing little player. Even the name is weird. How do I pronounce this, "hi dies", "hits", what is it? I need to tell my friends. It has features that I will probably never use. It has a step counter?! The size is completely perfect, but in use, maybe a little too small. It is a quirky little thing, but once you figure it out and you accept the quirks, the sound is amazing. Menus are intuitive and easy. Options to adjust sound seem endless. Out of the box with a pair of Grado SR80s, this thing sounds incredible. So much sparkle. After reading some reviews about the player online, I made further adjustments to MSEB ("Mage Sound 8-ball Tuning"... what is that magic? It really works!) to extend bass ever so slightly. This really balanced things even more than they were. Adding a tinge (.25) of soundfield also gave the music slightly more space. Now I'm obsessed with listening to this thing. I usually listen to music with EQ off and have left that feature alone, but MSEB and soundfield have really added to the music experience. The more time I spend with this little guy, the more I like it. It's completely stashable with huge sound. It reminds me of how I felt with the gen 1 Apple Ipod Shuffle. I can take it anywhere, it sounds great and I don't worry about thrashing it. I'm going to try the DAC function next. I highly recommend this player.
