I am kind of looking at the HD650, HD 599. I was looking at the DT770 but eh. Information on rtings shows the soundstage on the dt770 is poorer.
the 599 looks better due to the connector and could get cables easier for it plus its cheaper. I could save the money and use it for a microphone and an amp if I need one which I found others on here say the 599 don't need an amp.
Non US but all three im looking at I can get locally or amazon/official site.
