According to Baidu Aigou, the price difference between Shiyi and Wang Yin is mainly due to their production and material quality. Yiguan song-ordering machine uses imported materials, but the production materials in Wang Yin are relatively poor, so Yiguan song-ordering machine is more expensive. When buying a jukebox, materials and functions are important factors in determining the price. Easy music machine adopts high-quality materials, such as high-definition picture processor and video decoder, high-quality sound system and durable and reliable mechanical parts. In contrast, Wang Yin's song-ordering machine has less strict requirements on materials, which leads to its relatively low price.
