• Appearance: When we hold the headphones in our hands, they appear three-dimensional. After wearing them, the visual experience becomes flat. The panel design of the headphones compresses the curved surfaces and graphic textures of 3D space into 2D space, making it look like a rich and varied three-dimensional picture
• Craftsmanship simplifies complexity, transforming disorder into a flat and orderly layout. These components are arranged in just the right positions, ensuring both aesthetics and production consistency
• Performance, single dynamic coil+four dynamic iron, using a physical three-way structure. Its speaker unit module has been optimized by multiple MOONDROP pre made headphones, and the ddhifi tuning concept has been introduced. Combined with a specially developed crossover circuit board, it brings a new auditory experience. The three frequency distribution is balanced and smooth, and it has a solid and durable listening experience in the middle and low frequencies
