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.
Large-scale Finite Element Simulation System to Assist Design
The MOONDROP R&D department acoustic development team conducted three Electricity-Force-Sound simulations utilizing a dedicated high-performance computer and the high-end COMSOL large-scale finite element simulation system. These simulations optimized acoustic structure design, reduced experimental trial-and-error time, improved R&D efficiency, and created a solid foundation for the R&D team to pursue the upper limits of product performance.
Universal Dual 3.5mm Interchangeable Design
Cosmo adopts a universal double 3.5mm interchangeable cable design with an inclined angle, allowing users to freely change cables to meet different needs.
The stock cable is a 4.4mm balanced cable made of single-crystal copper, and comes with a balanced-to-single-ended adapter.
Natural, Open, Laid Back, High Quality
Smooth Wide-band Response Ultra-low Nonlinear Distortion
Thanks to the innovative application of new electro-acoustic technology and patented acoustic structure design, Cosmo achieves superior acoustic performance equal to classic high-end flagship headphones.
3D Structure of Front and Rear Cavity High-frequency Phase Control Waveguide
Cosmo innovatively adds three-dimensional independent high-frequency phase control waveguide components on both sides of the diaphragm to greatly reduce the phase cancellation caused by reflection and diffraction of medium-high frequency and high-frequency sound waves in the front and rear cavities, so that the treble tone is smoother and more delicate, and the sound image is more open and real.
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 to ensure the uniform and efficient distribution of the magnetic field over the vibrating surface.
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. This technology results in low-split vibration far superior to traditional planar magnetic headphones and comparable to that of electrostatics.
Patented FDT Full Drive Technology
-- Traditional Planar Magnetic Headphone Diaphragm Circuit
Effective and ineffective driving circuits co-exist in the vibration area, and only the central part of the diaphragm is driven, generating large split vibrations that cause burrs in treble details and distortion of timbre.
-- FDT Full Drive Technology
The vibrating part of the diaphragm is placed in a uniform planar magnetic field, and effective drive circuits extend over the entire area of the vibrating surface. This exerts a uniform full-surface driving force comparable to that of electrostatic headphones, eliminating split vibrations and delivering a treble performance far superior to that of traditional planar magnetic headphones.
Patent No.: CN219740589U
Effective driving circuits refer to the part of the circuit laid on the diaphragm of the planar magnetic headphone parallel to the grid magnets. Effective driving of the diaphragm can only be achieved if the orientation of the circuit is perpendicular to the magnetic induction field and the vibration direction of the diaphragm. Other parts of the circuit are ineffective, serving only to conduct current without producing the force necessary to drive the diaphragm.
The MOONDROP R&D team leverages years of experience and technological know-how to create a more beautiful timbre for you.
