Features 1. 10mm dual-cavity internal magnetic high-performance dynamic driver combines with the first generation DLC composite diaphragm, delivering excellent transient response and high resolution sound details. 2. The newly designed high-frequency phase waveguide effectively reduces the distortion caused by high-frequency phase interference. 3. The metal cavity made by complex processing is in line with the ergonomics and takes into account aesthetic design. 4. Uses a composite cavity, Multiple tuning holes, and multiple acoustic dampers with different parameters for accurate frequency response adjustment, to deliver an exceptionally satisfying listening experience. 5. The frequency responce is highly in line with HRTF and room response functio, and optimizes the modern recording, offers a real timbre performance and a sufficient atmosphere. 6. Standard nylon woven surface 0.78pin silver-plated cable.
