Summary: I bought these cans 2 years ago and sold them to get the ATH-M50, which then lead me into the audio world.
Overall these are good portable headphones with great build quality. The sound, however, is where these are suffer.
I liked the idea of picking a custom headband/wires/driver to match your style.
The overall sound presentation is very congested and muffled. There is no clarity or detail. The bass, though, is fairly good.
Pros: Bassy, great build quality, interchangeable parts, looks great, customization.
