It doesn't have a battery and it doesn't have to. As the object looks pretty modern and cool, aesthetically pleasing. I didn't have time to explore much. I did a few CDs in FLAC and WAVE. The speed of ripping is not impressive. I can't assess quality. I am not an audiophile or an expert. FLAC is not in the most compressed form and I can't find any information if I can have control over this on my device. I am curious if you can have software, which will work on computers the same way as it works with Gracenote on Astell&norma SR25.
