Sony is mainly famous for its best sound quality. However this model NWZ-A844 sound reception is very poor. Even a normal local MP4 player would produce a better sound than this model. The outer parts gets faded away very quickly. The battery doesn’t even last for 2 hours. The first thing to get faulty way is the battery. I don’t think so it is worth for money product. The video resolution is the only thing which is satisfying overall. The audio jack point gets damaged very quickly. Since we use it during our travel mode, I suppose the quality to be a first class one and not like this
