Drawing inspiration from acclaimed series such as \u003cem\u003ePiano Forte\u003c\/em\u003e and \u003cem\u003eHeaven\u003c\/em\u003e, the S4000 introduces new technologies to combine the precision of balanced armature drivers with the tonal character of metal housings, delivering a pure and emotionally engaging listening experience.\u003c\/p\u003e\n\u003ch2\u003eMirror Image Dynamic Driver Module\u003c\/h2\u003e\n\u003cp\u003eIn the S‑Series, final employs \u003cstrong\u003etwo open‑back full‑range BA drivers arranged in a mirror image configuration\u003c\/strong\u003e. This layout increases air throughput and helps the S4000 present an airy, extended sound with fine musical detail. By mirroring the drivers, their vibration behavior becomes more consistent, allowing resonances to cancel each other out and resulting in improved stability, \u003cstrong\u003elower distortion\u003c\/strong\u003e, and cleaner overall reproduction.\u003c\/p\u003e\n\u003ch2\u003eTone Chamber System – Stainless Steel \u0026amp; Brass Acoustic Path\u003c\/h2\u003e\n\u003cp\u003eThe \u003cstrong\u003eS4000 housings are made from stainless steel\u003c\/strong\u003e with a blast finish, while the \u003cstrong\u003esound tubes are crafted from brass\u003c\/strong\u003e. As sound travels through the brass nozzle, it picks up a unique tonal character shaped by the metal’s properties. At the front of the nozzle, concentric circular elements form a narrow sound emission point, creating diffraction that enhances spatiality and immersion. This \u003cstrong\u003eTone Chamber System\u003c\/strong\u003e expands the perceived soundstage and wraps the listener in a more enveloping acoustic field.\u003c\/p\u003e\n\u003ch2\u003eSoft Silver‑Plated Cable \u0026amp; Fusion G Eartips\u003c\/h2\u003e\n\u003cp\u003eThe \u003cstrong\u003efinal S4000\u003c\/strong\u003e is equipped with a proprietary \u003cstrong\u003eeight‑strand soft silver‑plated copper cable\u003c\/strong\u003e, designed to transmit smooth, clear mid‑high frequencies while minimizing handling noise and the “stethoscope effect” caused by cable friction. The 0.78 mm 2‑pin connectors and splitter share matching colors with the earphones, giving the entire system a cohesive, premium appearance.\u003c\/p\u003e\n\u003cp\u003eTo optimize sound transmission, final includes its next‑generation \u003cstrong\u003eFusion G eartips\u003c\/strong\u003e. These hybrid tips combine a high‑density foam surface for excellent sealing and comfort with a \u003cstrong\u003ewide sound bore\u003c\/strong\u003e for extended treble and a spacious presentation. Grooved hard silicone in the sound tube adapts to different ear canal shapes, ensuring a stable fit and allowing fine details to be delivered clearly to the listener.\u003c\/p\u003e\n\u003ch2\u003eTuning Orientation\u003c\/h2\u003e\n\u003cp\u003eTaking advantage of the acoustic properties of stainless steel, the \u003cstrong\u003eS4000\u003c\/strong\u003e emphasizes \u003cstrong\u003eclear, bright mid‑high frequency imaging\u003c\/strong\u003e.
