I had these for awhile. I liked the intimacy and bass. They sure look cool, too. They are nicely portable, able to fold up, and having 2 detachable cords. But the bass was a little too impactful for me to listen for extended periods. The earpieces tended to heat up my ears a bit more than usual as well. They sounded pretty good out of my HA-1 as well as my receiver. But I never used them much, because I usually use my open phones.
