Moondrop Horizon 50mm ULT Dynamic Driver Open Back Headphone

Newly Designed High-Performance 50mm ULT Dynamic Driver

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.



Titanium-Plated PEN Dome + Double-Layer Liquid Silica Gel Suspension Composite Diaphragm

To achieve treble extension in the diaphragm of a 50mm large-sized driver, it is essential to balance rigidity and damping. After extensive simulation calculations of material characteristics and over ten optimization experiments with diaphragm samples.



High Sensitivity and Low Impedance for Easy Driving Wide Compatibility

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. 



Rich, Expansive, and Smooth Sound Perfect Tri-frequencies Balance, Naturally Authentic Timbre

The frequency response characteristics of Horizon align with the VDSF standard, thanks to the newly designed 50mm ULT dynamic driver. With a free-field fo as low as 80Hz, it delivers sub-bass performance that is rare in open dynamic driver headphones.
