Copper Crystal

Unleashing all potential of your IEM, Copper Crystal features a realistic restoration of musicality, offers the cleanest and detailed sounding in each recording. Either vocal live performance or chamber music, Copper Crystal can restore each note from every movement, with astonishing sounding. 

With the combination of FlashAcoustic’s SCOCC and Silver clay Furukawa’s Silver-Copper Alloy, achieving the desired acoustic performance of metal. SCOCC offers the finest details in high frequencies while Silver clay silver-copper alloy is responsible for the whole sound thickness over the overall acoustic spectrum. Therefore, the overall sounding of Copper Crystal is neutral and realistic.

1. What is SCOCC?

SCOCC was first developed by Flash Acoustics in 2017. The full name of SCOCC is Sub-critical annealing CRYO Ohno-Continuous-Casting.  Precise heat and cryo treatment were both applied to the wire manufacturing process. Ensuring the direction of copper crystal has an omnidirectional crystallization within every single step of cable manufacturing. 

2. What is the advantage of Furukawas Silver-Copper Alloy?

Silver-Copper has an awesome acoustic performance due to its 96%(IASC) conductivity. Furukawas Silver-Copper Alloy was specially designed for high-frequency transmission in digital communication. Therefore, ultra-high frequency extension is incredibly impressive after applying Silver-Copper alloy into the conductor.
