Trendy Sound Tuning

Illuminate Your Music Journey
TRN CS4 features precise tuning with a relaxed, atmospheric low-frequency, transparent mid-frequency, and high-frequency solid resolution. The frequency distribution is uniform, and the overall style is biased towards pop. This can bring us a more realistic and moving music enjoyment, closer to the original recording effect, and let us feel as if we are on the scene.

Strong Dual-Magnet Design

Core Power Output
TRN CS4 is equipped with a dual-magnet design. The diaphragm uses a high-polymer composite diaphragm. Unlike the high-rigidity diaphragm popular on the market, TRN CS4 uses a light, medium-rigidity, and good elasticity high-polymer diaphragm. Combined with carefully designed patterns, it can achieve lower distortion and better music performance. The double magnetic flux provides a strong thrust, making the sound field wider, transient, and dynamic, with full expressiveness. Low, mid, and high frequencies are responsible for their duties, restoring the essence of sound and accurately presenting every sound detail.
