The player will play mp3 and mp4. Included were two memory cards, but only the MicroSD fit in, the other is like a free gift for other devices. The device is very slim and is made of a hard plastic case. It is therefore very easy, you do not feel it. However, the housing does not creaks and is stable.
As an MP3 player in a soundscape of public transport the device is sufficient. Let's see how long the Accu holds. I had a (here will not specify the brand names) 64GB model. After one year, was out of the bi-weekly charge, a week. After less than two years, I invite now to three times a week. And that with a playing time of just under 5 hours a week. Unfortunately, this is the silly to such devices, even if they cost Unmegen, the built-in rechargable batteries. Again, the Accu is permanently installed.
The music quality is good and traffic is audible (The volume knob goes up to a 40's brand and that's very loud).
The menu is a little getting used to, and partly in order to achieve the music directories, designed a little illogical. But to get it very quickly. The buttons on the key thrust washer can be operated comfortably and easily. In addition, there is a radio function and the sound can be adjusted accordingly. You can play directory entries. To select a directory and the therein contained songs, you have to click on the top menu key, otherwise one falls back to the previous folder being played. Ie not with the center button, as it is common in other devices. As written, a little illogical menu navigation.
Playing on the computer, the player was immediately recognized and the data transfer worked very well. He is the data transfer as fast or slow as other MP3 players, which I had so far.
A star deduction I give in addition to the menu for the screen. To be represented Scripture in light blue on a white background, is probably troublesome even for young eyes. For this, the lettering is kept very tender. You can read it, but could have been made clearer.
Conclusion: a cheaper Player, if you so want, through multiple microSD card brings a lot of memory.
