The Horizon features MOONDROP’s latest generation of high-performance 50mm ULT dynamic driver. After two years of extensive research, development, and optimization, we have significantly improved the dynamic range, reduced distortion, and expanded the bandwidth, achieving leading levels compared to previous products.
Titanium-Plated PEN Dome +Double-Layer Liquid Silica Gel Suspension Composite Diaphragm. we have ultimately selected a diaphragm material that fulfills the requirements for long stroke, full frequency response, and low nonlinearity.
To create a wider soundstage and ensure complete auricle coupling for an enhanced listening experience, the Horizon features a newly designed large-angle driver inclined structure. This design allows sound waves radiated by the driver to travel a more complete path, arriving from the oblique front. This not only facilitates auricle coupling but also promotes natural diffusion at various angles through a high sound transmission structure.
The frequency response characteristics of Horizon align with the VDSF standard, thanks to the newly designed 50mm ULT dynamic driver. With a free-field f0 as low as 80Hz, it delivers sub-bass performance that is rare in open dynamic driver headphones, while also providing smooth high-frequency responses typical of larger dynamic drivers. This results in punchy dynamics and a laid-back sound profile.
With its high-performance magnetic circuit, even a large composite diaphragm can be easily driven. The Horizon can be powered by an integrated sound card from a computer or a portable device, making it suitable for gaming. When connected to a powerful desktop amplifier, it can unlock even greater performance capabilities.
