AudioQuest Dragonfly is a U-disk shaped ear amplifier decoder, which is introduced by the line trench AudioQuest. Its discussion and response at home and abroad are quite good, and the sound quality can be assured. There is also a dragonfly lamp, which performs color transformation according to different input sampling rates. I have personally used similar products, which can significantly improve the output sound quality of the notebook.

AudioQuest Dragonfly has a historical low price of 99 dollars, about 600 yuan, and the price is about 700 yuan. Taobao is still at the pace of 1100+. There are similar products in China that cost 1000 yuan, but this is still good.
