They have been playing now for well over 120hrs and I feel the bass has settled in nicely. I don't find it as pronounced as the beginning yet it remains detailed, articulate, tight and deep. The rest of the spectrum has settled in beautifully as well. Of course, this could just be my ears getting used to the FA-011's sound. YMMV.
One thing that hasn't changed...THESE ARE SO COMFY!!!!!!
