I dont really take this sub or anysub to be honest, too seriously
So I don t know if I really trust review on here, because even if the guy is qualify to do the review you don t know his taste really.
Being 4 years into the hobby you should know what you like or not and the taste of the most famous reviewer on YT for exemple if Z says a headphone is bright its probably gonna be too bright for me ect ect
For people being negative its probably just “elitism” and the few louder one
And about your upgrade sadly the best ways will always be to listen to the headphones on your radar by yourself
