Don’t listen to so many poisonous articles on the Internet. I have never heard of Golden Chrysanthemum, so I will not comment on it. I have a million-level speaker system at home, a set of Berlin Sound, and dozens of headphones, ranging from 3,500 to 10,000-level headphones. For portable use, the quality of c4 is definitely better than that of 901. The analysis, imaging, positioning and sound field are all better. When c4 and 901s are connected to the sound system as the sound source, the sound amplification is very obvious. This can be experienced even on the portable earphone ie800. Yes, many people listen to music by reading other people’s posts and following what others say is good. Some people listen to music and keep it in their head. It is very important to establish your own listening sense. The sound of c4 also has shortcomings, after all, it is portable.
