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 was very skeptical about buying this product but for above average reviews on YouTube vlogs. I had already purchased the Sony Walkman NW- A105 as well as the NW-A45. So, I had some reference points. In a word, this product is "surprising". I didn't expect this level of quality from a product in this price range. This unit has a few major things going for it vs its Sony Walkman counterparts. First things first, the Sony Walkman music transfer to a micro SD card on a Mac is a serious pain in the ass and is uncomfortably glitchy. On this Hidisz ap80 pro- x, it's a breeze. Just put your micro sd card into the unit and then select "Update Database" and within a minute or two, you are good to. The sound of the Hidisz is on the bright side, but not uncomfortable at all. I tested this out with the Meze 99 Classics as well as the Massdrop/Sennheiser HD6xx. With a normal 3.5 mm, the Hidisz can drive the Meze's with no problem. With the Senneiser, it can't. So, I bought a pair of balanced cables and plugged them into the headphones and the 2.5mm "balanced" headphone jack on the unit and the difference was incredible. It could drive the Sennheiser (300ohm impedance) with no problem without a headphone amp. Incredible is the now the word I have to use. All of this in a tiny unit for under $200 at the time I bought these. The value is outstanding and I would not hesitate to recommend them. The user interface is easy and fuss free. With all of this said, here are a few things to note and consider:1. The newest Sony Walkman NW-A105 sounds a bit better. The sound is more full and drawn out, it is noticeable. However the Sony is $350 vs the Hidisz at around $200. The Sony Walkman interface is ok, but, who the hell wants an android device sucking up all of that battery life. I really don't need to be online to enjoy music- otherwise, I would use my phone. The difference in sound is not worth the price if you are watching your pennies.2. If you hook up the Hidisz to a headphone amp (I have a Modi/Magni Heresey Schiit stack and can get through about two albums of about 2 hours until it drains the battery on the Hidisz. As such, you can get around this battery drain by getting balanced cables on the 6xx or using a headphone like the Meze 99 classics which does not require a lot of juice to drive it.3. The sound on the Sony Walkman NW-A45 (a few years older a model that the Sony Walkman NW-A105) is not as good as the Hidisz (regular 3.5) jack. Go figure. But, I like this model Walkman because you are not connected to Wifi and the battery life is great compared to the terrible battery life on the Walkman NW-A105. So, in reality, you should choose between the Hidisz and the NW-A105.Again if you want a slightly better sound with terrible battery life, annoying Android bloatware, a VERY confusing and cumbersome process of transferring files to the external micro sd card, and a cost of almost twice as much, go with the Walkman. But, in my opinion, the better value with almost as good as sound goes to the Hidisz hands down. You simply cannot beat this for under $200. It's easy to use and again, "surprisingly" good if not great.The only reason I am giving this a 4 star rating is because as a device there are better options out there. If I were grading it on the value, it would be 5 starts. But, strictly on the product itself, it's a solid 4 star.I did a lot of research on this before I bought all three DAP's. I am telling you, the Hidisz is no joke.

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.
