jsmiller58Yo I already got em on the 2nd of dec. Really great headphones. I know the dt177x is closed back but the sundaras really hit those outta the park man. Really good. I feel like a real upgrade to the sundaras would probably be a focal elex/clear or some zmf. Looking at the koss esp. or audio technica r70x rn though.
tristan_castroElex is most definitely an upgrade, in my opinion, over the Sundara, and quite a bit over the Phantom...
Elex > Sundara >> Thieaudio Phantom
