Well its the first time i have bought from MASSDROP and i can tell you I think its going to be my new place to get quality items for an outstanding price. Now about these headphones, I have been waiting for these to become available for a while now. And it was certainly the best headphone purchase i have ever made. my other set is the Sennheiser 595. I thought the were good but these AKG"s blew me away, simply amazing. i generally listen to Tidal or Qobuz with my desk top pc thru a Sanskrit 6th gen dac to a JDS LABS O2 Headphone Amp.
