AGPTEK 16GB USB C MP3 Player, A55S 2 in 1 Type-C & USB Stick Music Player

Review for the AGPTEK U3. Under the batter cover though a small opening, you can see the computer chip that is used in this device, an Actions Semiconductor ATJ331X from 2010. I was able to find the datasheet online. Datasheet mentions is supports WMA and other digital audio standards. I tested a plethora of formats but only MP3, WMA, and WAV files play. It can play CBR and VBR made with the LAME encoder, haven't yet found an mp3 which cannot. Assumes WAV files are voice recordings, as it displays the voice record symbol on the screen, not that it effects the sound in anyway. You could upload music as WAV files if you really wanted to. The screen shows the bit rate of the file being played. CD rips to WAV display as WAV 999 on the screen. The bit rate is actually 1411 but the display can only show three digits. If you are playing a variable bit rate file, it will update and change the displayed bit rate several times a second. The slow LCD display has ghosting issues, so the bit rate can be somewhat hard to read for VBR files. Still, that's a neat feature. Has a variable speed playback setting. Allowing you to playback slower or faster than normal. The audio seems to be monaural or lower quality in some way when the speed is set to anything other than normal. The display shows a small frequency band amplitude visualization, and it seems to actually update following the music instead of just being a cycling animation. Another small but neat feature. Music fades out instead of shutting off instantly when changing songs. Songs are organized by folder, and by the order in which they were uploaded to the device, NOT alphanumerically or by metadata! For example, if track 05 is uploaded to this device first, then track 01, track 05 will play first and track 01 after. This causes issues if you copy whole folders to the device as the tracks might not be copied to the device by your file manager in proper order. So, you have to copy one track to the U3 at a time, from first to last, if you want tracks to playback in the same order as they are on the album. This device also doesn't support any playlists, only folders. All in all, it's an efficient and simple portable music player with built in FM radio, a replaceable AAA battery, SD card expansion storage, and good sound quality for low impedance headphones.

This is an excellent mp3 music player for use with wired headphones. The sound quality is great and it has several preset EQ settings. It has shuffle or alphabetical play modes. I use the high quality Eveready AAA Lithium battery that lasts for months of use and I keep a spare one in my carry on bag that with keep it's charge for over 10 years . If your mp3 library has all the correct ID tags information (Title, Author, Genre, Album) it will be easy to find the tune you are looking for PLUS the info will display on the screen. Don't get hung up on the small 8GB internal memory. The internal memory is USB 2.0 at best and might be USB 1.0. Write speeds are very slow, but playback is fine. I use a high quality 64GB micro SD card that makes adding music fast and easy. The controls take some time getting used to, but once you master them it's not a problem. The beauty of this player is that it is small and lightweight. The downside is that it's small and the control buttons have multiple functions. Can't have it both ways. If you like heavy and large, then carry your iPad with you to play music. The bottom line is take the time to learn the menu and you'll enjoy this player. I've tried many wireless Bluetooth headphones and they don't have the sound quality as the wired units. If you can live with wires then you'll like this mp3 player.

First of all, the price was more than right for this little guy! And the fact that it uses AAA batteries (this unit is NOT rechargeable) is a plus for most. The sound quality is really good (it even has a little 4-band equalizer), and the fact that it doesn't have either wifi or bluetooth is more than OK for me. The 64GB microSD card is also a nice touch. Basically everything about this little guy works really well, plus it is very simple to operate. The only caveat for me with this little unit, is just that - it is small, very small. The controls are too small for an old guy like me to be able to handle with a lot of clumsiness on my part (with my short, stubby fingers), and the display is far too small for these ol' eyes of mine to see very well. But, those ARE NOT THE FAULT OF THE PRODUCT, OR THE MANUFACTURER. I simply chose a player that was inappropriate for my needs and abilities. It is better suited for younger eyes with more nimble fingers than mine. If you are looking for a small device to use in your car's stereo system, this will be a good choice for you. As for me and my fat fingers and bad eyes, I am going to try a bigger unit with larger buttons and controls.

I am one of those people (like many of you) in a desperate quest to find a good AAA battery mp3 player. In my opinion, the best ones ever made were all by Coby, but none of the Cobys are still manufactured. Starting in 2009, I’ve bought 8 Coby players over the years, and only one of them has ever stopped working. (I own so many in part because I like to have different audiobooks going at the same time, because I use a few of them for sleeping music, and because I wanted some extra in case I never get to buy a quality AAA battery mp3 player again.) In case anyone has no idea why AAA battery mp3 players are superior to all other choices, this is because: 1. eneloop nimh rechargeable batteries are incredibly cheap per usage and last longer than most of us will. (The amazon brand imitations of eneloops are great too.) 2. if you carry an extra AAA battery with you, then you basically have unlimited power because you can easily change batteries and never have to stop listening. Having an extra AAA battery for a AAA mp3 player makes the player feel like it is solar powered--I *never* have to stop listening. 3. nimh batteries DO NOT BLOW UP OR CATCH FIRE. All lithium batteries are capable of doing this, but nimh can’t. For me this is a deal breaker for all non-AAA players. 4. nimh batteries can sit in the car all day in the Texas Summer heat and be fine. I’ve got eneloops from 2009 that have spent 8 straight Summers baking in the car like potatoes, and I still can’t tell the old ones from the new ones. Lithium batteries are not as tough. 5. AAA batteries can be replaced, so an AAA player could last decades. Lately, I tried out three AAA battery mp3 players: 1) the AGPtEK U3 8GB mp3 player 2) the 8GB USB 2.0 Flash Drive LCD Mini MP3 Music Player w FM Radio Voice Recorder (the kind that you can find trivial variations of everywhere on Amazon, and that always has that keychain ring sticking out of a cylinder on the end) 3) and the Naxa MP3 Player with 4GB Built-in Flash Memory, LCD Display, PLL Digital FM Radio and Built-In USB Plug Adapter (that I bought at Frys). All three of these products count as the worst three products that I have purchased in the last 5 years, in any category. The Naxa player occasionally fails to read mp3 files from the early 2000s (that every other mp3 player ever made can easily play), is impossible to use without looking at it (bad for driving), and is very cheap in quality. It’s constant changing of backlight colors is the most stupid idea ever thought up by an engineer, and you can’t stop it from doing this. The one with the keychain ring arrived broken-in-advance (this is a famous specialty of the makers of that product--if it arrives working properly it means you have a fairy godmother or something). Mine does not rewind, ever, and that is seriously annoying. This product WAS the worst product that I ever bought in the last 5 years, until the AGPtEK. The AGPtEK seems well made, with higher build quality than most, but it has a design flaw that is absolutely maddening--it’s volume buttons and forward/back buttons are all attached on the same wheel, and are way to sensitive/imprecise for that setup. This means that you cannot change volume without risking suddenly skipping forward or back one track. No matter how carefully you try, even if you are doing nothing else and staring right at the player, it is very easy to accidentally skip tracks forward or back when you try to change the volume. Every single time you try to change the volume by one tick, you have about a 1 in 6 chance of changing tracks by mistake. (And that is only if you are staring at the player and concentrating. If you are driving you have at least a 1 in 3 chance of skipping tracks by mistake.) This problem will ruin your life, especially if you listen while driving and have to change volumes depending on how fast you are now going. I hope that AGPtEK will make another model with separate buttons for volume control. AGPtEK seems to make good products, and they may be the only company capable and willing to make a good AAA battery mp3 player. If so, I will happily buy it and add on to this review to tell everyone of the improvement. If anyone finds a good AAA battery mp3 player, please comment on this review to let me know. To help us all out in the quest to find a good AAA mp3 player, please like this review so that more people notice it. Good luck!

First off, the AGPTek U3 MP3 player is for people who don't like having to plug their MP3 player in too charge it. It takes a regular AAA battery which is nice. When the battery dies you just slide a new one in. I bought a package of rechargeable AAA batteries and just used one after another until there was one left, then I would charge all the ones that needed charging. Easy. It's particularly useful when you out in the middle of nowhere and your battery dies. You simply carry an extra battery on you and you're good to go. It's convenient and this one lasts for about 24 hours straight on a single battery. I used this device for about 14 hours a day since about 2017 and it worked whenever I needed. Those are the positives. Here is the bad: the USB cover does not stay on very well. You will probably lose it quickly. The battery cover doesn't stay on very well either, this is especially true when the USB cover is missing. Once these covers are lost you're stuck with an MP3 player with no USB or Battery cover. When I lost my covers I used a rubber band to keep the battery in place. It looks tacky but it's effective. I even got a buddy to make a leather case for it to keep the battery in, but I found out that the rubber band is more convenient. Also, the battery spring is actually pretty good so the battery will actually stay in place without a cover or rubber band most of the time. The menu sucks, but you can't expect to have a good menu with an MP3 player the size of a portable aspirin case. Apart from having a hard time pushing the right button because they are so small (this thing is designed for fingers the size of a Barbie doll), the only real problem I had with the menu was the fact that the menu would occasionally go wonky and get offset. If it does this then pull the battery out, wait 30 seconds, put it back in, and problem solved. So, the AGPtek USB cover and battery cover will eventually get lost and the menu sucks, apart from that, it was an extremely reliable MP3 player for about 5 years of 14 hour a day use. It always worked. After five years the connection for the Earphone/headphones became separated or broken inside so now I get static audio. I just bought a replacement for it and I'm back and running. Thank goodness I never had to contact their support or I might have had an entirely different experience. Since I had a mixed Good and Bad experience I gave it a three stars. For the price it's a decent deal, just know what you're getting. I wish you the best of luck.

Thank to you all who posted your reviews, which had a huge impact on me selecting to purchase 2 of these mp3 players. After hearing Apple would discontinue producing ipods, I thought what one large company does, others follow. I needed to replace my COBY purchased in 2009. I agree with many of the positive responses, where people were looking for an mp3 player that (1) uses recharging batteries and (2) used a USB plug. (After all, it isn’t difficult to have spare batteries available and why use an additional chord. Extra note: Yes, my cell phone can play music but I’d prefer not to use my expensive cell phone for a simple task, wearing out both the machine and battery.) I don’t want fancy screens, which can use more power. I just want to simply listen to my selected music. When doing my homework for this product, there weren’t a lot of choices. I’ve only opened up one box for now. Easily was able to copy the music from my old mp3 to the new one. I used BOSE ear buds and thought the sound was just as good (or many even a little better) then my old COBY, using the same ear buds. I don’t have big hands so using the arrows was not difficult. Design-wise I would’ve liked to not have to “select” volume instead of a separate button which controls volume, but I understand based on the design, why that was done. Not a flaw, just an adjustment in use. In honestly, I have not tried the other features. Nice to have but basically, I just like to listen to music I’ve selected. So far I just haven’t had the opportunity to use this product as much as I normally would. As long as it remains working, I would recommend this product.

Worked amazing for me , I have rechargeable AAA batteries.. big plus is being able to move mysi straight from my phone to the player .

After my 3rd iPod Classic battery stopped charging, I refused to pay another $60 to get another one. I was so sick of getting a device that would have been perfectly fine if I could replace the battery, but, of course, Apple makes the task nearly impossible. So, I set about finding an mp3 player I could use when I went running that would take a normal, REPLACEABLE, battery. This is the one! I put in a AA battery, and navigated to settings. It took me a minute or two to figure out how to set the time, and about 2 more minutes to sync music (with Media Monkey on Windows 10) and play the songs. Those complaining that the interface is difficult to learn, probably had their VCR blinking 12:00 too. Don't get me wrong, it's not great, but it's what you would expect from a device that is so small. The sound is amazing from this little guy! Since I just want to turn it on/off (press and hold play/pause), play mp3s (press play), skip and go back (arrows), and shuffle (set mode to random--works contrary to another reviewer's comment), I don't care about the voice recording, replay (looping of audio), or the FM radio. I'm not going to mess with the variable speed playback, etc. either. So, I can't speak to those features if you are looking for those things. But the basics meet my needs. I'm done with devices without replaceable batteries. EDIT: Removing one star, as the 'random' mode is not 'shuffle.' It will randomly pick from all songs, not from ones not yet played. If you have 5 songs, each time you have a 20% chance of replaying the same song upon hitting next. If 50 songs, a 2% chance. 07.31.2019 Update: Removing more stars. The thing finally died. The player has big problems. I had to remove the battery after every use, otherwise the device would drain the battery over a day or so. Also the tab on the battery door broke so the door was easily lost. The cap was lost. The navigation button stopped working. The sound stopped coming out of one ear. I bought the Tomameri Portable MP3/MP4 Player to replace it: (https://www.amazon.com/gp/product/B07S82H7SL). It is much much better.

Me sorprendió para bien, para ser un mp3 a pilas esta muy modernizado, incluso te dice la hora. Tengo su versión antigua y las diferencias son enormes, el Agptek A55PL es más cómodo de usar y los botones son fáciles de apretar, la batería va bien depende de cuantas horas escuches, me encanta que pueda pasar música desde mi móvil conectándolo a él copiar pegar y listo! lo último importante es que si quieres escuchar música en carpetas no vayas a "Música", ve a la carpeta de "Archivos" y cuando te metas ve al "Customize Playist" ahí se encuentra las carpetas más otras 3 carpetas incluidas del mp3 por si quieres meter cosas ahí. Si deseas un mp3 a pilas para enfrentar apagones o hacer un viaje tipo mochilero lo recomiendo totalmente.

Oh wow. I really like this. No waiting for recharge just swap out the battery. I wanted something that could survive not being near a charger and this is it. I get about 14 hours continuous use with a well known gold topped battery which is great especially as I like to listen to audio books. The screen, whilst small, is perfectly serviceable for what it needs to do and the sound is great. Now, this player has no internal storage so it is all on a micro SD card. This may sound like a negative, but it means there’s no messing about picking which storage location to use, so actually this decision makes this little gem even better. All in all, if you want an MP3 player that isn’t reliant on an internal battery that will eventually die, then this is it. One point to note is that the folder view is by far the easiest to use but it lists in the order the files are put onto the SD card, so a little forethought when loading files will go a long way.

INCREASE VOLUME SOUND..VERY LESS..USER FUNCTION IS HARD..

I purchased this to use on a long multi-day cycling race that wouldn't have regular access to power. My intention was to load a multi-part audiobook on and listen to it as i rode - replacing the AAA battery as needed. Unfortunately, it's not a great interface for navigating files or playing in file name order. This would be perfect for music, and any single file audiobooks. I have no real regrets, just a better understanding of it's limitations and how I'll use it in the future. I've stuck some velcro onto the back of the stick as a method of attaching to things. It's held up well and is great for just playing a shuffled playlist of music.

Ich wollte für Reisen/ unterwegs sein nicht immer meinen Minidisk Player und Minidisks mitnehmen. Eine Alternative musste her. Aber, ein MP3 Player, den man aufladen muss kam für mich nicht infrage. Man hat ja nicht immer die Möglichkeit zu laden. Nach langem suchen fand ich diesen MP3 Player, der mit Batterien läuft. Was soll ich sagen, ich bin total erstaunt, was für eine Power das kleine Teil hat. Angeschlossen an meinem J. on T. Lautsprecher klingt es für mich richtig gut. Bin na klar kein Musikexperte, und es gibt bestimmt hochwertigere Teile. Aber für mich reicht der Klang aus. Ich finde es auch super, dass man u.a. auch mit normalen Überspielkabel Musik aufnehmen kann und nicht erst die Musik runter laden muss. Er hat allerdings kein Bluetooth. Brauche ich persönlich auch nicht. Für mich ist das ein wirklich gutes Teil, was sich nicht hinter meinem Minidisk verstecken muss. Sollte sich irgendwas ändern, passe ich na klar meine Rezesion an.
