58x/6xx to a Sundara

Thats so weird my 770s dont do it at all.

I just spent a lot of money testing some headphones so I am gonna wait to get a refund on these two pairs. I dont know if I want to try the Sundaras yet. I am really trying to find an open pair.
I just posted this describing the sound signature I prefer. I consider the 177x to be my holy grail for headphone signature but they just dont fit me right UGH
