10mm Dual Magnetic Dynamic Driver
CCA CST adopts a large size dual magnetic dynamic driver with double magnetic improved sound quality. The low frequency dynamic surge, detailed and rich resolution, especially for middle and high frequency voice performance, more full and sweet
5mm Large Sound Guide Tube
For CST, we adopt the classic large-diameter sound tube design which is about 1mm larger in diameter than the conentional sound tube and strengthens the performance of the shocking low frequency of the dual magnetic dynamic
Unique and Comfortable Fit
The curved catheter design fits the auricle naturally and comfortably. It is comfortable to wear for a long time and has good sound insulation effect
Detailed Craftsmanship
CCA CST adopts the wood for the cavity and along with the metal dust-proof steel mesh to avoid dust getting in the cavity to block the sound unit. L/R is marked on each earbud for easy identification
OFC Copper Cable
The included oxygen-free copper cable provide superior signal transmission performance with various characteristics such as resistance to pulling and reducing corrosion. Included 3 pairs of difference sizes of silicone eartips are soft and comfortable for various types ear canals
