something else
I was thinking and asking my self , why we aren't all of us in the same city or country all of us , to meet each other from this forum in real life ? and if we had this possibility ,we could build a company with headphones, iems, Cables etc .
I believe we would have the best company in the world with the best headphones in the world easily.
We are amazing
