B01 Mini Portable FM Radio USB Player, TF/SD Card/USB Slot Support Mp3 Play Rec,Pocket Walkman Small Radio with Lock Key,Wristband,Rechargeable Battery Operated, Excellent Reception and Sound

I tested this FM radio receiver and MP3 player and it seems to work good enough and the sound that comes out of it sounds good enough and it charges it's battery O.K, I did not try a USB flash drive, I put MP3 songs into a microSDHC card and they played good, too bad that it did not also have an AM band radio receiver and too bad that it is not also a MP4 player, of course, it would need to have a much bigger screen, all in all, it is a nice and good enough FM radio and MP3 player.

Very well made. Great reception, light weight and loud. Got one for my friends too

Good sound for the size but I wish the battery was user replaceable. I'm taking one point away for the permanent battery issue.

This little radio is one of the best little radios in the market today. It is very loud. It sounds beautiful and it is also an mp3 player. It is so small you can actually take it along with you anywhere. Battery life lasts for hours. I love this little radio so much I purchased 3 more in different styles from the same company. You will be amazed at how easy it is to use and the memory capacity it also has built in. This is truly a great radio and a great buy.

I was looking for a way to listen to Miles Davis and John Coltrane while at work. This little device was the perfect solution. Plug in a USB flash drive and listen to hours of great music. Super sound quality and very inexpensive. Also, easy to charge the internal battery and simple to operate.

I originally wrote a 5-star review for this portable radio, but I've now gone through three of them. Each one stopped working properly after a few weeks - and now, they randomly power down after a few seconds of use. I'm returning the lot.

The orange screen in the photo is wrong... it's red like the other listings and sources for the same device. I like the old school mp3 players for just turn-on-and-play operation without having to mess with over complicated stuff so was looking for something like that. Was looking for something without touch buttons because the mp3 players with touch buttons always go out on me. Mechanical buttons go out on me often enough but that's another story. But the old school mp3 players are horribly limited on how many mp3s you can put on a card and many of them weren't well made anyway. I've a 128 gb micro SD card in this thing and it seems to be working. A lot of mp3 players have terrible battery life. Haven't run this thing down yet and using the speaker. Docs say it can only play mp3 which I assume to mean that it ignores mp4 files but it might be worth converting them to mp3 if that is the case. I need to test. So except for maybe that, this is checking all of the boxes for me, of what I've been looking for. I'm not interested in FM radio, but the built in speaker is nice. It's larger than most mp3 players, about the size of a shorter, thicker cassette tape. I figured that even if the micro SD card slot didn't take high capacity SD cards, I could get a large USB drive and put it in there, but SD does work, and testing the same SD card with a USB adapter, a 128gb SD card works too. Going to try even larger. Sound in the little built in speaker is definitely not bad for personal-area use when you aren't in a really loud place. Digging the retro 7 segment display. It tells you the number, in order of directory listing, of the mp3 file it is playing, apparently. That has a nice retro vibe. My Diamond Rio PMP300, one of the very first mp3 players, is the same in that regard (but it's LCD instead of plasma/LED/whatever glowing 7 segments they used. My mp3s aren't super high bitrate. I think it's mostly 128kbps or VBR around there. Someone else was complaining about skips but with this bitrate and a Samsung micro SD, I'm not having problems there. It's favoring the Mojo Nixon right now which is putting it on my good side but I assume it'll spread it around more later.Update: Less than 4 hours in, I hit a software bug where it got stuck. One of the mp3s might be corrupted or it has some issue, but when it tries to play that mp3, it locks up. When it does that, you can't skip to the next song. It sits at the spinning animation with 00:00 displayed, indefinitely (I left it like that for about 15 minutes). Trying to power it off and back on again, it immediately goes back and tries to play the same song and locks up again. If you take the SD card out and play from USB drive for a while, then switch back to the SD card, instead of playing a different song on the SD card, it still tries to pick up where it left off on the SD card and play the same one. I tried to remove the mp3 that I thought it was getting stuck on just by numeric order, but I missed for some reason.Also confirmed that it does not play mp4s. With some more testing and software updates to support mp4/m4a, this could be really good.

Very nice tiny radio with great sound.the usb port works great.i like that it's rechargeable, battery life is good. I have another handrail a little bigger and it doesn't sound no where near as good as this little radio.
