Personally, the player is worth around $40. I say this because I bought the player with some expectations. These are strong Bluetooth and higher interface adaptability. I bought the Aiworth Bluetooth mp3 player before and it was a good product, but it had a button interface, not a touchscreen. This was a problem for me as I have hundreds of mp3 files and scrolling through them one by one is very hard and eventually I lost that player. So I bought this one with the scrolling in mind. The overall for this product is that its Bluetooth is relatively easy to use, and it has a good amount of internal storage, (I personally have around 4 gigs of music, so it was not quite enough) So I installed a micro SD card. The various apps are kind of useless for an mp3 player. Like the recorder and calculator apps really don't need to be there. but the video and gallery apps are a plus because they split up the files. The video quality is incredible, I was surprised, to say the least, shocked would be better, at the amazing quality. The clock and alarm function are okay, not really necessary, that is what a phone is for. But the settings and Bluetooth apps make for a great platform to work with the various functions. The battery life is good, I have not reached a limit yet, I just charge it like my phone whenever I can. There is one glitch that I have found, that is when I let it go to sleep, and wake it up to pause the streaming music, sometimes it will freeze the music app and will not respond, the other apps will work fine, but the music app just stops working. So I just restart it and then it works fine. So other than that, this player is well worth the money.

I bought these unit, got my music converted to MP3 files, that was a challenge, but then I got these MP3 files on to two of these MP3 players, TIMMKOO MP3 player w/ Bluetooth (both models QE3 & the Q5), wow!!! music sounds crystal clear on both. I've played them on M-Audio BX5 Speakers with a Presonus Micro Station BT, all purchased on Amazon, it's awesome, you'll have an eargasm, you'll hear sounds in your favorites you never knew were there. I haven't used the TIMMKOO for much else other than listening to music, but there are other things both of these can do, but all I wanted was a couple of music players that worked. I take it to the gym and listen on Sony Linkbuds and other earbuds I have as back-ups. Overall, I'm impressed with a real solution to overpriced music players, this is reasonable priced in my opinion. I can listen for 2 hours/ day and go 4 days without charging the TIMMKOO, I mostly use the QE3 at the gym. I put a TF card with 512GB capacity in both the QE3 & the Q5 and I probably have not used more than 128GB, the TF card can only read/write at 120MB/s and the music sounds so great. TIMMKOO works!

This is definitely a good MP3 player for my car or work outs. I normally like to keep this ins my car so I do not have to plug my phone in all the time. The reason being is that I don't want my phone to be drained or taxed playing music. This product right out of the box is very well packaged. It provides you with the type C USB cable, headphones, and a clear case for the MP3 player. The headphones feel a bit cheap so I do recommend purchasing a better pair. It is Bluetooth capable so you can use Bluetooth headphones if you wish. The first thing I have to say about it is that the front facing glass is beautiful. It is not something that you can easily scratch and provides a nice clear video. The user interface is pretty simple and easy to use. The interface has several different functions from video to reading ebooks. For ebooks it seems to be okay with reading just PDF books which is really nice. The only issue is that I do not want to read on such a small screen. It does have a pretty good radio on it. I did not have too many static issues. It is a nice thing to have when I need to go to those drive in movie theaters. I do not have to use my car radio and risk running my battery out. The battery life varies depending on what you use it for. From what I can tell it can last on average 10 to 12 hours on headphones and 4-5 hours on speakers with movie running. The charge time varies as well and charges via type c usb cable. The speakers are pretty good and could be used as a standalone if you wished. The arm band that comes with it is definitely not a one size fit all. I think it works well for the average person but if you are bulked out on the arms you may have issues with fitting. I think 8 gb is enough but it does have a micro SD card slot if you wish for more music and video. It can be expanded to 128 gb. I have not tried my bigger SD cards but 128 gb works fine to me. Although it can be a bit laggy scrolling through all the songs trying to read music from hte SD card. The video quality can run at 1080p. It does not have any games on it unfortunately. Honestly it is a great thing to have if you are trying to keep your kids busy as well. You can load this device with cartoons and such and just play from this device rather than your phone. The clear case is nice and protective from scratches but it is easy to take sun damage. I would recommend putting the case on as the back is glossy and prone to scratches. Overall, this Mp3 player does the job for what I want. It plays music, videos, and can even read ebooks. It has a pretty good battery life and takes the strain off my phone.

I have tested 3 of the six cheap music players, and this one so far, and I don't see it getting beaten, punches WAY above its weight. $50, decently large 4.5in (480x800) IPS screen with an interface and navigation scheme that's not dumb. The other two which are also touch based, have obtuse swiping gestures, but since this has a home and a back button, it feels familiar to those who have used Android (this doesn't run Android).

Pros (THERE ARE A LOT OF THEM)
-Great screen, decent enough resolution and is truly IPS, now it's not 178 all angles great, but it's far better than the cheap TN panels I've dealt with with the other two 10 dollar cheaper media players.
-Features: Good features, randomly has a built in dictionary, I don't know why, but it's there and it's kind of neat. The on-board microphone is actually pretty decent, sensitive, and you need to do some post processing to mitigate background noise but better than just throwing a cheap one in there.
-User Experience: Everything seems to work, you touch it, and it works, has press and hold to enter selection mode and then can easily add multiple things into a collection when in music mode to make a playlist. The keyboard that's on screen for the dictionary is nice and responsive, also not very small, very usable on this tiny device.
-Quality: for $50 you're getting a lot of it here, decent screen, above average built in speaker that gets decently loud enough, a 4 pole headphone/mic jack. A microSD card slot that can ACTUALLY accept cards larger than 128, tried a 256GB and it hadn't any issue. The build is great, glass and metal where you need and want them Comes with a decent silicon case and two screen protectors. Thing charges up fast thanks to USB C, during a 15 minute video transfer, it topped off the battery as well which was about 50% full. Decent brightness and darkness with no real light bleed or issue. Came with a very weird 4 ended connector, don't know what that's for. It's a micro b and usb C connector on both ends, with both connectors coming out to form a Y. Very interesting and unique cable. Also, the headphones, something this cheap comes with decent headphones. The cable is braided, and the quality are nice, not Samsung Galaxy AKG bundled headphones nice, but not cheap dime store ones either, the earpiece is metal as well. AGAIN, a lot of weird quality for such a budget device.

Cons:
Music Play Back: Music sounds fine, and in and of itself, plays well, too. Great scanning and searching feature, no lag skipping through a song to get to a hook. THOUGH, and this is an annoying THOUGH, seems to have a big bug. When playing songs from a folder it will sometimes play a random song besides the one you pressed. I don't know why that is. One theory and not enough testing has happened to verify it fully, is that if you play a song from one folder, and then go into another folder and decide to play a song from that folder. It doesn't interupt the song and change to the new one, it plays a random one which I think is in the previous folder that the song you were listening to but in the position you pressed. So song two from folder A would play even if you press song two from folder B. Very odd.

Keep in mind:
This isn't an android device or a proper ipod touch like device, keep expectations realistic. I loaded an 8GB video from my SD card and it took a while to lode, and initial playback was weird. Audio syncing issues that seemed to correct itself when enough of the video got buffered. It played well after that.

While the screen is IPS, it's also prone to washing out, which was more apparent in the video test I ran.

This also doesn't come with ANYTHING but the dictionary installed as far as content goes. No photos to show off the good display. No sample music to test that out. No video sample either. BUT, OTG works flawlessly.

SO FAR, this is a huge recommend.

I bought this for my mom for Christmas so that she wouldn't have to carry around all of her CDs. There was a slight learning curve but since the touch interface is similar to a phone (which was why I chose this one after looking at many mp3 players) she figured it out pretty quickly and loves having all her music on a tiny device. It takes a while to load a lot of music but it's cool that you can load it on whatever size mini SD and you could have multiple or just one big one. It's a little laggy sometimes with so much music on it but it doesn't seem to bother my mom. She loves it.
