Moondrop COSMO 100mm Flagship FDT Planar Driver Headphone

Large 100mm Diaphragm In contrast to traditional planar magnetic headphones, Cosmo adopts an ultra-large 100mm-diameter diaphragm incorporating Full Drive Technology (FDT). The entire vibrating surface of the diaphragm is evenly covered with effective driving circuits and enclosed in a magnetic field. Nanoscale Ultra-thin Diaphragm The ultra-thin low-tension diaphragm substrate with a thickness of approx. 500nm meets the requirements of a wider frequency band, lower dive, and faster detail response speed, delivering exceptional high quality. Highly Elastic Ultra-thin Pure Silver Etched Circuit The highly elastic pure silver circuit made of ultra-thin silver film ensures high efficiency/low heat loss and uniform stress. TBT Diaphragm Secondary Stress Balance Technology With the help of TBT (Tension Balancing Technology) diaphragm surface tension is subjected to secondary balancing processing, thus greatly eliminating large dynamic distortion and ensuring more stable high quality. N52 Magnet Array Optimized by FEA Finite Element Analysis The Cosmo planar magnetic headphone adopts an array of 36 extra-large N52 neodymium strip magnets to generate a planar magnetic field covering the entire vibrating surface of the diaphragm, optimized by FEA finite element simulation. Universal Dual 3.5mm Interchangeable Design Cosmo adopts a universal double 3.5mm interchangeable cable design with an inclined angle. The stock cable is a 4.4mm balanced cable made of single-crystal copper, and comes with a balanced-to-single-ended adapter.
