TRUTHEAR x Crinacle ZERO: RED - Dual Dynamic Drivers In-Ear Headphone IEM

  • Adopt dual polyurethane suspension composite liquid-crystal dome diaphragm N52 Rubidium magnet double- cavity internal magnetic circuit dynamic driver.
  • Using a DLP-3D printing cavity, usually reserved for high-end multi-drivers products and custom earphones, and the hand-made glue dropping and capping process.
  • Equipped with copper-plated silver cable with thicker diameter of single strand. Deliver outstanding objective indicators.
  • TRUTHEAR not only pursues excellent objective measurements, but also attaches great importance to the optimization and improvement of processing technology; The cavity of ZERO:RED is still a sandwich-like structure (front cavity, decorative panel, and a few drops of glue to fill the seams).
  • ZERO:RED houses double dynamic driver configuration, with a diameter of 10mm and the other diameter of 7.8mm, the mature internal magnetic circuit structure co-worked with flexible polyurethane suspension composite LCP liquid crystal dome diaphragm, but it has total different inner configuration between standard ZERO, which makes RED offer a better objective indicators while meeting the needs of R&D.
