TIMMKOO 72GB MP3 Player with Bluetooth, 4.0" Full Touchscreen Mp4 Mp3 Player with Speaker, Portable HiFi Sound Mp3 Music Player with Bluetooth, Voice Recorder, Supports up to 512GB TF Card (Black)

i bought the non wifi bluetooth version. works great! came with an sd card (64gb), but i had one to use already, and it read it right away. android os, I just wish it was easier to load an app on it as i wanted to use a specific music player. battery life is ok. it's definitely better with bluetooth off. overall, I'm happy with it and will buy another if this one breaks.

This Mp3 player is a great way to access your music without having to use your phone. I use it to have music playing wherever I don't want to risk having my phone laying around (Beach, outdoor event, helping play music at a friends party). The sound quality is really good as long as you connect it to a Bluetooth speaker or headphones. The speakers on the player itself are weak and you can barely hear them in a quiet room so make sure to listen with headphones or a speaker. This player also works well for reading eBooks on the go. I tested out the Voice Recorder function and am happy with it as its good to have if needed. While it doesn't have much in-built storage, it allows up to a 512gb micro sd card so that should more than cover the amount of music and books I would need to have on me. I like that it also uses a USB-C to charge as this allows it to charge faster. Overall I think its a great mp3 player but my only complaints is that it doesn't run android so you cannot install any apps like Spotify or kindle. If using this player make sure that you have your music, eBooks, etc. downloaded as that's the only way you can transfer any music on to it.
