7. What's the shell material of the FH7S?

 

The FH7S features a design resembling that of armor seen in sci-fi, futuristic weaponry and machinery. On the faceplate of the FH7S lie neat layers of carefully-placed holes stacked upon each other that form its semi-open design. These are combined with silver and gold trim as well as air guide nets for a meticulous balance between form and function. Finally, the FH7S still retains an overall rounded shape that perfectly fits the human ear for comfortable extended listening sessions. The outer shell is made of aluminium alloy, processed by 5-axis CNC machining.
