Flagship Planar Magnetic Headphone

Meet the Moondrop Cosmo, featuring a flagship 100mm planar magnetic driver designed for detailed and high-fidelity audio reproduction. The large driver size facilitates a stronger bass response and greater sound clarity, capturing detailed audio nuances across a broad frequency range. The increased driver surface area contributes to a more expansive soundstage, giving a clearer sense of space and positioning in the audio. 

Ultra-thin 500um diaphragm

The Moondrop Cosmo's ultra-thin 500-micron diaphragm delivers unparalleled precision and clarity, making it ideal for audiophiles who value detailed and accurate audio reproduction. At the heart of this technology is a 100mm nanoscale diaphragm that's significantly thinner than those found in traditional dynamic driver headphones. The thinness of the diaphragm allows for a broader frequency range and quicker response times, which ensures that every note is captured with exquisite detail. 

Pure silver-etched circuit

The Moondrop Cosmo's pure silver-etched circuit ensures consistent, high-quality audio performance with a prolonged lifespan, perfectly suited for daily rigorous use. This circuit is made from a highly elastic, ultra-thin silver film that excels in electrical efficiency and minimizes heat loss. Silver's superior conductivity lowers resistance, enabling audio signals to transmit with enhanced clarity and strength. Additionally, silver's properties facilitate uniform stress distribution across the circuit, which reduces the risk of mechanical failures and contributes to the durability of the headphones. This design ultimately maximizes energy transfer, ensuring that the Cosmo maintains its audio performance over time without degradation caused by heat.

100mm Full Drive Technology

The Moondrop Cosmo delivers audio clarity and precision that rival the performance of electrostatic headphones, enhancing every listen with cleaner, more accurate sound reproduction. This exceptional quality is achieved through its expansive 100mm diaphragm, which employs Full Drive Technology (FDT). Unlike traditional planar magnetic headphones, the Cosmo's design ensures that the entire vibrating surface of the diaphragm is uniformly activated by effective driving circuits and is encapsulated within a consistent magnetic field. 

Universal Dual 3.5mm Interchangeable Design

The Moondrop Cosmo features a versatile dual 3.5mm interchangeable cable design, incorporating an angled connection that enhances user convenience and flexibility. This design allows listeners to easily swap cables to suit various audio setups, ensuring compatibility across a range of devices. Included with the Cosmo is a premium 4.4mm balanced cable crafted from single-crystal copper, known for its superior conductivity and audio clarity.
