Introducing Cosmo, the brand-new flagship planar headphone that blends cutting-edge scientific tuning with exceptional craftsmanship. Boasting a full-size 100mm planar driver, the Nanoscale ultra-thin diaphragm, and a highly elastic ultra-thin pure silver etched circuit, Cosmo delivers unparalleled stable sound. We invite you to check it out now!

Let's see the graph first.

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.

Additionally, Cosmo uses a 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 exceptionally high quality.
The highly elastic pure silver circuit made of ultra-thin silver film ensures high efficiency/low heat loss and uniform stress.
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.

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.

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.

In terms of the vital part, sound performance, 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. The smoother wide-band amplitude-frequency response characteristics of highly-matched VDSF bring to Cosmo an open soundstage, a more extended timbre, excellent details, punchy dynamics, and burr-free treble. Even at sound pressures exceeding 1Pa, Cosmo can achieve ultra-low nonlinear distortion below 0.05% across almost the entire frequency range, enabling it to offer a pure, uncolored, relaxed, natural, and stable timbre, and reach the quality level of high-end desktop systems.

By the way, we're glad to present our newest Earhook, EVO, featuring dual ES9318 decoding chip built-in, priced at US$89.99. Now, It comes with a universal 0.78mm 2pin jack for wider compatibility and supports aptX Adaptive for high-quality, low-latency transmission. If you're looking for a wireless setup for your favorite earphones, give it a shot!

Any questions, suggestions, and feedback are welcome.
