AGPTEK U3 USB Stick Mp3 Player, 40GB Music Player Supports Replaceable AAA Battery, Recording, FM Radio, Expandable Up to 128GB

This little battery-operated Mp3 player works great and is compatible with blue tooth.

I really wanted to like this device but it has enough issues to make it borderline unusable. I love the battery, it is very necessary especially since the software crashes and removing it is the only way to reboot the device. It also burns through batteries quickly so carry a spare and maybe remove the battery when not using the device (I never remember). It takes a long time to transfer music (far longer than putting it on a usb) and some songs end up compressed so parts are sped up and sound robotic. Wish this worked better, like that it has two memory cards, but for $40 the device shouldn't crash practically every time I use it. Finally, the UI is quite slow and the buttons only work sometimes.

Love this! These players are gard to find and I love it. Exactly what I was looking for.

Old school tech for pure music enjoyment!! No streaming subsciptions to pay for, no endlessly annoying advertisements before and after every song, no bluetooth, no BS. Just load the music from your CD collection and push play!

I painted the red part of mine purple, and I liked the idea because you can listen to music right on it by plugging earbuds right in it, but it does not work! It stores files and records files, but you can not listen to them on there. Very misleading, but it is good to have extra storage for files, so that's okay.

Most of the other negative reviews covered the obvious points: unreadable screen, awful UI, poor audio quality, etc. Several reviews mention it won't play the song you choose, instead playing a random one. I've figured out why. The player claims to support cards up to 128GB. However, only the first 2GB of music is actually playable. The player scans through the files, adding their compressed sizes to a running total. Once it reaches 2GB, the scanning stops, and any files after that are silentlly ignored if chosen.

I think my overall thoughts are that this thing COULD be good using what is there already. I can only imagine that this would strongly persuade someone from listening to music, or trying to listen to music. The controls are compact and cramped, and I hope you weren't trying to have safely accessible volume control, because you're gonna have to hold down R/V and << and >> instead of just being able to press a button. Firstly, these have 8GB internal storage. Expansion says up to 128tb sd. Not sure how sloggy that is/did not test. Please note that there are different versions of this 8GB product, and that this appears to be why they are being sold as such. Other reviews explain that the new 2023 version organizes files differently, has some kind of weird "Backend Play" feature when you incorrectly thumb for the volume (was this something for recording?? the manual doesn't mention it.), and if it does or doesn't talk to your computer based on if the battery is in. I can't tell you anything about the old version, because I did not end up purchasing it. If I had known, I would have tried to buy the other version. Out of box, my brand new mp3 player had a broken line in the screen about 1/4 of the way down. This did not make the experience of trying the product out for the first time very intuitive, to be fair. However, it wasn't just that. I went to the Radio mode and tediously held down << and >> to scroll through stations. My unit could not pick up a single station. I don't know if other units are able to do this, so I can't even tell you how the radio is when the product is new. It feels sturdy. The buttons on the front feel very responsive, but usability and file navigation, even after practice, is difficult. If I had seen that the volume buttons weren't dedicated, I wouldn't have bothered, long story short. The UI itself makes learning navigation feel somewhat arcane and fingercrampy. There are so few features on this that you think they could be done correctly, but it feels almost intentionally like a bad product. It looks like a good product. If you aren't tuned into how it will function and what you want from it, you might not notice the control issue until you start trying to use it. I really like the shape of the body. If the bottom button wasn't used as an Fn key (you have to hold it down and it does take a few seconds) to access the volume, and there were dedicated volume buttons on the side, I would try to order another. I don't want to spend time tediously holding down buttons to do something that should be easy, like turning up or down the volume. If the UI looked better, if the controls were better, if it seemed like a lasting product- I might consider getting one of these again. But the bad UI/controls/advertised features THAT DOOOOON'T WOOOOOORK - I had to return mine. If it wasn't broken, I would still return it due to the clunky volume button issue.

I am happy that it is AAA battery powered, USB seems to connect to Windows just fine. The only issue I have is how the first 20 (of 40) songs played perfect that I put on it; and songs 21 thru 30 seemed to brick up the device every third song until I re-downloaded the mp3s from a different source and made sure it was 128 bitrate and it seemed to work. It seems to have trouble with random mp3 files and they ones it has trouble with seem to have higher bitrate then 128; however it will play a couple mp3s of higher bitrate just fine so I am confused as to what makes some mp3s brick this up as most seem to work fine. I have a 15 year old RCA I found which is much better but good luck finding another one. These are very hard to find in USA in 2025. This is adequate if you are computer literate about downloading or converting mp3s. It connects to my car via 3.5mm Aux cable that cost me $6 at dollar store. I really like it because it works in my car and runs on AAA battery and NOT my cell battery which is great. 4 stars if I didn't have to redownload so many mp3s would have been 5.

laradio llego bien suena bien la pega es que no consigo escuchar el mpe3 las canciones segidas no lo acabo de entender por lo demas bien

Bonjour super baladeur Mp3 simple et efficace très bon son une pile a remplacer et ces tous les écouteurs ne son pas fournie mais ces pas plus mal on peut choisir les sien

Ce baladeur à pile est très bien, niveau sonore très bon mais ça dépend aussi des écouteurs non fourni je précise ni la pile mais quand on acquiert ce produit mieux vaut être déjà équipé, prise casque correct, langues européennes et asiatiques, manuel d’utilisation en français, carte micro sd fourni, enfin le transfert de fichiers a parfaitement fonctionné sous Windows xp , j’ignore les autres versions de Windows mais cela doit être impeccable tout comme la version Mac Un produit durable vu que j’ai eu un baladeur équivalent qui dure depuis 13 ans mais qui était pas possible d’insérer de micro cartes sd pour stoker plus de données, côté commandes c’était pareil donc aucun soucis je précise pour finir que j’ai pas essayé le tuner fm ni la fonction Dictaphone de l’appareil. Un bon produit

Impossible de copier un fichier dedans, j'ai du recevoir un modèle défectueux. Je n'avais pas ce soucis avec un autre modèle MP3 agptek. Celui ci refuse le transfert par USB alors que je vois bien la mémoire du MP3 sur le pc. Simplement la copie refuse de se faire et j'ai un message d'erreur.

Creo que la estrella ya lo dice todo, no voy a enumerar los problemas porque el reproductor ya a sido devuelto, y es una pena, pues es bonito, pequeño y comodo, pero los fallos son demasiado importantes como para quedarselo. Una de dos, o bien me a tocado el defectuoso o esque no se manejarlo (mejor la primera opción) sin embargo, después de ver tanta reseña de problematica del mismo mp3, te fijas en la frase de la caja que dice (Nos esforzamos para mejorar y bla bla bla) siento ser tan critico, pero a mi modo de ver, ya de tendria que haber puesto solucion a la problematica del mp3 y mas hoy en dia por los supuestos avances en la tecnologia, y digo supuestos porque no solo este mp3, otros tambien entran en el pack de los mal echos, materiales de muy baja calidad entre otros. Curioso porque estas cosas en los años anteriores no pasaba, ahora te peta un chip o condensador o multiplicador o lo que sea en un pis pas. En fin, monaguillo me hago el dia que se dejen de hacer ciertos productos electronicos con tan malos componentes, como digo, no solo este mp3, hay muchas más cosas electronicas nefastas.
