We designed the M1/F1 as our flagship model, making no compromise. The result is a sound that is powerful, dynamic and highly sophisticated. The M1/F1 represents a major step forward in cutting edge technology having inherited and improved upon the advanced technologies of our P/C series.
Based on the technology of M1/F1, we have achieved to create P-004/C-004 as its cost-performance by integrating the features of M1/F1 and P/C series.
As well as other P/C seires audio plugs, the core of P-004/C-004 is composed of the selection of materials, plating technology, and usablity.

Inheriting the most core factor of M1/F1, the contacts of P-004/C-004 are made of beryllium copper which insures mechanical integrity and high conductivity. The plating is also same as M1/F1 that is a combination of platinum and palladium which was selected after repeated listening tests.
The body is made of 30% glass filled PBT which has excellent machine-ability and provides superior electrical isolation. And the outer cover of P/C series is made of PC(PolyCarbonate) for its rigidity and hardness. In addition, its "Black-Diamond" color of P-004/C-004 outer cover represents its emotional and exciting sound.
