Three star deduction, because the supplied headphones create a permanent noise. I've connected my own ear headphones because the noise was gone. The build quality is not good, the USB plug for charging is something wrong in the body, so it is difficult to plug in the charging cable.
The battery lasts not really long, I would estimate 3-4 hours. The unit should thus not be offered, require rather more and prove it clever headphone and provide a longer battery life.
