Beyerdynamic Aventho 200 Zwart

Unable to find any reviews, I relied on a single mixed review I found online to decide to order these headphones so I could form my own opinion, and unfortunately I am not satisfied with them. Even when I set the equaliser to "V" as I usually do, the sound remains very flat. The sound produced is not musical at all. The only positive points I noted were the good quality of the materials, the comfort, and the comprehensive companion app. I have initiated the return process and will be sending it back tomorrow.
