So I recently came into owning a HP100, and I am new to audiophile community but I can say that it sounds fantastic for the price I was able to buy it at, very content. I was looking for an open headphone originally especially because I have not tried one my whole adult life. I ended up being surprised by how nice the clarity, sound quality, bass response, and even the sound stage is for the HP100. I then woke up to a gift from my girl and she had bought me the DT990 pro, and she said she wanted to get my the HP200(she knew that was the one I wanted) but she was able to get the DT for 129 new(imo both sound amazing, I believe the HP is easier to listen too off the rip but that may because it was also burned in for a while) I am actually waiting for the Fiio e11 for an amp to put with the HP, and you said it makes a well match?
