Dual-driver structure

Restoring the true sound
TRN MT4 Pro has also made key improvements in upgrade and optimization. It uses two different dynamic drivers, which provide excellent sound characteristics. The 10mm DLC diamond-like carbon diaphragm dual-chamber dynamic driver has a high hardness and rigidity, which can provide excellent audio transmission.

At the same time, the dual-chamber design can more accurately control the air pressure to make the diaphragm movement smoother, the sound field more grand, and the sound details richer. The 6mm titanium-plated diaphragm dynamic driver has high rigidity and lightweight characteristics, which can provide more accurate and precise audio output. This dynamic driver has high sensitivity and wide frequency response, which can quickly and sensitively respond to audio signals and present accurate and delicate sound details.

Combining these dynamic drivers can provide excellent sound characteristics such as high resolution, rich low-frequency response, accurate details, and wide-frequency response, allowing you to feel the realism and purity of music deeply.

Optimized sound chamber

For a more immersive sound experience
To achieve a better reproduction of sound and sound field, we have carefully optimized the sound chamber of the TRN MT4 Pro. The ingenious design of the sound chamber structure and volume ensures the accurate propagation of audio waves, making them more clear and accurate. This optimization allows the headphones to exhibit outstanding performance in terms of frequency response and phase response. The professional design of the cavity makes the low-frequency sound richer and fuller and the high-frequency sound more accurate and delicate. The sound field performance of the headphones has also been greatly improved, allowing you to feel a wider, more three-dimensional, and realistic music space.
