ddHiFi has come up with an all-new pair of multi-driver hybrid in-ear monitors, the ddHiFi Surface. With a five-driver hybrid setup featuring one dynamic driver and quad-balanced armature drivers, the ddHiFi Surface promises a smooth, balanced, lively sound response. The pair features a precisely designed acoustic chamber with physical acoustic tubes and a specially designed frequency crossover board, This brings a three-way crossover delivering a clean and crisp sound response with ultra-low distortion. Professional acoustic engineers at ddHiFi have adjusted the tuning o the Surface for a fresh auditory experience. Bring home the ddHiFi Surface to dive deeper into your favorite music!!

Ultimate Craftsmanship:-

ddHiFi is known for its ultimate level craftsmanship. From high-quality cables to dedicated DAC/AMPs and adapters, they have shown top-class craftsmanship with their products. The latest ddHiFi Surface has that trusted feeling here as well. We have solid ear shells that feature a metallic face cover and a 3D-printed transparent inner shell. They have designed a CNC-machined aluminum material socket protection cover. It protects the 2-pin socket on the IEM. The IEM itself looks very clean and premium.

Five-Driver Awesomeness:-

ddHiFi Surface brings a five-driver hybrid setup on each side. The pair adopts traditional DD BA architecture featuring one dynamic driver and four balanced armature drivers. The drivers are carefully chosen, the driver module actually has optimized structure from various previous models by Moondrop. Using ddHiFi’s professional tuning philosophy,  the pair brings a refreshing auditory experience for its users.

Three-Way Physical Electronic Crossover:-

In order to get the best out of each driver here and allow them to produce a coherent sound with ultra-low distortion, ddHiFi has designed the Surface with an electronic physical crossover design. This includes a precisely crafted 3D printed acoustic chamber that has three physical acoustic ducts. These ducts are designed with proper calculations to achieve the desired sound response. Secondly, we have a professionally designed electronic crossover board as well.

High-Purity Stock Cable:-

ddHiFi bundles the Surface IEMs with a high-purity stock cable. The pair comes with ddHiFi’s very own BC120S cable. This cable has a high-purity, oxygen-free copper with silver-plating wire configuration. It has a 4-strand, cross-braided Litz structure cable with a proper shielded design. It adopts standard 0.78mm 2-pin connectors and comes with a fixed 4.4mm balanced termination.
