Both O2 and Dragonfly were platforms for listening to novels online, but their positioning and characteristics were slightly different. The oxygen listening platform was an online platform that focused on listening to novels. It provided various types of novels, including audio novels, serial novels, and completed novels. The advantage of oxygen listening to books was that it provided a wealth of novel resources and the host's voice quality and performance were relatively good. In addition, oxygen listening also provided some special functions such as recommending novels, searching for novels, and bookshelf management. Dragonfly PM, on the other hand, was more focused on music and radio applications, providing various types of music, radio stations, and radio programs. The advantage of Dragonfly PM was that it provided a wide range of music and radio resources, and its rich content types could meet the preferences of different users. In addition, Dragonfly PM also provided some special features such as live streaming, Short videos, and social interaction. Therefore, which one was better depended on the specific needs and preferences. If you prefer novel resources and anchors with better sound quality, then reading with oxygen might be more suitable. If you prefer music and radio applications, then dragonfly might be more suitable.
