I will never buy another pair of Juliet Palm Flats, even though they are very comfortable. Every now and then one would get stuck to in my toes and it just got really annoying. However, they are sized rather on the small side so we had to return. Once they arrived and i tried them on, i immediately ordered a second pair in another color. These are the best shoes to quickly get out the door. I have been amping the dt1990s with all kinds of stuff, but have found the best synergy with the Beyerdynamic A20 and the Lake People RS 02. They fit my wide feet perfect. It was easy to set up and it connects automatically every time. Some people who bought wont even notice the difference, but for audiophiles, they are a big let down. Here is my initial feedback -Sound Quality - Sound signature is V shape .
