Blackening Stainless Steel + Copper(Blue) 

The 9iNE uses copper for the back plate. The copper coloring is Copper Blue by Momentum Factory Orii, a beautiful bright blue coloring using rust.

The sound is a little thicker and flatter in the midrange than other 9iNEs. The highs and lows are also a little suppressed and mild, and the sound is light for a metal. The sound tends to be easier to listen to than to hear, and is recommended for long-time listening.

The stainless steel blackening “Gen” goes very well with Momentum Factory Orii’s brass and copper coloring. Cool!
