Moondrop Cosmo houses a full-sized 100mm planar magnetic driver which the brand has designed with great precision and quality. The driver has an ultra-thin nanoscale diaphragm with highly elastic pure-silver circuit etching. Moondrop has designed the Cosmo with large finite element simulation software. It has a dual-cavity design with a high-frequency phase waveguide system present in both front and rear cavities. Moondrop Cosmo features a universal 3.5mm dual plug design and comes bundled with a high-purity single-crystal copper cable with a 4.4mm balanced termination.\n\nFlagship Sound With Professionally Designed Driver:-\n\nMoondrop has designed a large 100mm planar magnetic driver for its flagship Headphones. The driver houses an ultra-thin low-tension diaphragm with a thickness of approximately 500nm. It has a highly elastic pure silver circuit etched onto the diaphragm. The ultra-thin silver film etching ensures high efficiency with low heat and uniform stress on the diaphragm.
