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 purchased my AP80 PRO-X back in June of 2022. I enjoyed listening to it with Sony WH-1000XM3 Wireless Noise-Canceling Over-Ear Headphones, especially with hi-res (24-bit, 48 kHz and above music files. The sound was tight and clear. Sometimes the treble was on the high end, but was adjustable whenever I felt like fiddling around with the sound settings. The display was bright and clear, but the navigation is a bit clunky and needs tweaking. Yet I still had an overall positive experience with the unit until a several days ago when the ALPS volume wheel ceased to function properly. The volume can still be adjusted, but pressing the volume wheel will not activate the screen or allow the unit to be powered off. The only way to wake up the screen is by connecting the unit to a computer or charging brick via a USB cable. It performed well for nearly 3 years and lasted over 1 year beyond it's warranty.

This product should be getting a much better review than it has been. Its look and feel say quality, and I couldn’t be happier with its performance. The owner’s manual leaves much to be desired, but Hidizs’s customer service is awesome. I have sent three emails to the company with questions about their product, and each one was answered within 24 hours and was extremely helpful.My biggest challenge initially was getting the micro SD card to stay in place. I have not had much experience with SD cards, so the fault was probably mine, but perseverance paid off. Once the card was in, transferring music files was a breeze. You need to run a scan each time you add music files, but the scan happens very quickly.Some reviewers have made negative comments about the player’s bluetooth capabilities. I have paired my player with a set of earbuds, a bluetooth speaker, and the sound system in my car, all without a problem. The sound through all of these devices is superb.Creating playlists is easy, as is adding songs to the playlists, but naming the playlists is the challenge due to the tiny “keyboard” with three or four letters on each key. (Remember texting on the old flip phones?) I discovered this workaround, however, which made the whole process much easier:(1) First name each playlist with a single letter or number and then choose the “save playlist” option. This will save the playlists to your SD card.(2) Connect the player to your computer and in your music list on the SD card you will find a folder called “playlist data”. You can then rename all of the playlists in that folder.(3) Eject the player from your computer, go back to the playlist screen on the player and choose “load playlist”. Your renamed playlists should now appear in the list, along with the original ones. Delete the originals and you are set. (To delete playlists, there is a little drop down button that you can almost see on the right side of the screen next to each playlist. Tap that and a menu will come up with a delete option. Same for deleting songs from a playlist.)There may be a way to create playlists on your computer first, but since I don’t use them that often, I didn’t pursue this option.
