I am the one who dislike nicehck graphene so much.(though I less talk about it) After I listened it around less than 3 hours, I decided to resale it and lucky that I could resale it successful, so you might need to rely on other people who share similar sound preference. Speaking of graphene, It recalls me about one Head-Fier here who was ever friendly shared his knowledge and opinions said that how much he dislike nicehck graphene earbuds and in that time, some guys here not only disagreed but also confronted & made sarcastic comments on him until he upset and leave this thread. What's a tragedy story.
