The Akais also had two detachable cords, but in its case they were both 1/8", one coiled and one not, and came with a 1/4" adapter... as "Professional Project" headphones, I thought it didn't make any sense that they wouldn't have a dedicated 1/4" jack, as what studio gear features 1/8" female jacks?

A longer cord would be nice, especially the 1/4" cord
