Blackening Stainless Steel + Copper.
This 9iNE uses copper for the back plate.
The tuning of the driver and internal filters is a little different from 9iNE and 9iNE-B. It is a little flatter and the overall sound is thicker and milder.
All copper is colored utilizing Momentum Factory Orii’s traditional techniques and is available in BLUE, COPPER RED, and COPPER PINK.
It is the easiest to listen to among the four 9iNEs. Also, the midrange is closer in sound than the other 9iNEs.
The copper is all colored for surface protection, and the colors and patterns are unique. If you enjoy Momentum Factory Orii, copper is the way to go!
