Title: Solid bass sounds muffle mid- to high-range
Review: I purchased these headphones and returned them the next day. For some of my music they sounded okay; however, I don't have many songs that really feature the bass, so these headphones were not for me. For much of my music, I felt the focus these headphones place on providing a rich bass caused the mid to upper range, including vocals, to sound muffled. I prefer my music a little more crisp and present. For those whose music can use more bass, these may be the headphones for you, but for me, they weren't.
