Advantages of metal and
polycarbonate hybrid

Installed metal housing by superfine aluminum cutting process.
For better sound quality and realize hi-fi sound,it applied unibody design from one solid material, there is no joint and protrusion, surprisingly, assembly is done by just two components.
Due to metal is fully covered the driver, united by one module until end of nozzle.

To maximizing features of the sound, special polycarbonate housing is chosen.
Stable sound ventilation and finished to cover metal housing for better musical pleasure.
