KBEAR Tourbillon-X

10mm CVD-Coated Carbon Fiber Diaphragm Dynamic Driver IEM

Precision of a Tourbillon. Soul of Music.

Engineered for those who demand precision in both build and sound, the KBEAR TRI Tourbillon-X combines horology-inspired mechanical aesthetics with advanced acoustic engineering. At its core lies a 10mm CVD-coated carbon fiber diaphragm dynamic driver—a single-driver configuration refined for low distortion, fast transient response, and exceptional vocal clarity. Drawing inspiration from the mechanical precision of a tourbillon watch, the TB-X features a distinctive zinc alloy gear-appearance design that symbolizes precise acoustic transmission. The CVD-coated carbon fiber diaphragm delivers 40% weight reduction, 3× increased rigidity, and reduced split vibration for cleaner high-frequency reproduction compared to traditional diaphragms. With an N52 neodymium magnet, external magnetic circuit design, and dual chamber structure, the TB-X achieves harmonic distortion below 0.03% @ 1kHz—comparable to electrostatic units. The tuning prioritizes vocal purity, instrument separation, and dynamic range, making it ideal for pop, acoustic music, and competitive gaming where precise audio imaging and spatial definition matter. The package includes a high-quality OFC silver-plated copper cable with 0.78mm 2-pin connectors and flexible termination options: 3.5mm (standard or with mic) and Type-C (with mic). Impedance of 19Ω, sensitivity of 100dB, and frequency response from 20Hz–20kHz ensure compatibility with smartphones, gaming devices, and dedicated audio players. Whether for Hi-Fi listening, mobile use, or competitive gaming, the TB-X delivers a rare balance of technical rigor and musical immersion—precision of a tourbillon, soul of music.
