I came across the HPH-200's today online. I instantly thought of Grados. Spontaneously i searched head-fi for reviews and only found one thread, in which a few members bought them and said they sound better than the Grado 60's, 80's, and 125's.
Why aren't these more popular? I'm thinking of picking up a pair myself, especially because they are marketed as studio monitors!
