The style of HD800 is different from that of HD600 and 650. The sound is relatively neutral and transparent, but it still has the style of Senhai. The most impressive thing about the 800 is its huge sound field, which is quite vast after being pushed. Compared with the HD600, the 800's tri band is more balanced, with less low-frequency sense, but far better texture. The 800 tri frequency density is good, the voice is a little far away, and it is relatively straightforward, calm, and lack of emotion. Many people say that 800 people's voices are not good. In fact, I think it is OK. As long as the taste is not bad, it sounds good, but it is not particularly brilliant. The 800 has strong control. When playing the big compilation, it is not disordered at all, with clear layers and precise positioning. But the 800 is more selective in the front end, which is easy to make bad noises.
