I purchased 4 of these MP3 players. I like the design and quality look, the light up dial is a plus and the memory card seem solid, but that's about it. On all four of these MP3 players, the speaker volume at max is low in both quality and sound, distorted and tinny.
There's a noticeable problem with the headphone jack where you have to wiggle the 3.5mm plug just right to get it to work. Sometimes the left ear bud will play, sometimes you'll have sound from the right ear bud, sometimes you will hear nothing, and sometimes even with the jack plugged all the way in, the music comes out of the tiny, tinny, distorted built in speaker.
I have a similar MP3 player which only has a 350mAh battery that claims to have up to 80 hours of playback time. That MP3 player has been in my car for 5 months, I've probably only used it 10 hours, but it hasn't been charged yet and the battery is still three quarters full. The listing description on this one reads that it has a bigger, 410mAh battery with a battery life of 24 hours playing time with Mp3 music, but length may vary depending on what you use it for. After fully charging 2 of the 4, setting them both on the table testing them side by side twice, playing only the MP3 music with the exact same songs, on all 4 test, the batteries only lasted around 4 to 5 hours, with the longest one being 5 hours and 17 minutes, but that one had the shortest time of less than 4 hours when tested a second time. Also it almost takes longer to charge these MP3 players than the actual playing time.
The FM radio is useless unless you plug the earphones in, but then again the earphone jacks are defective so it's a mute point unless you like listening to parts of a song sporadically through each side of the earbuds. Also the Manual is too small to read, even with my a magnifying glass.
