Moondrop JIU DSP Review

Moondrop JIU DSP – USB-C (Type-C) IEM

Following the success of Quarks DSP and Droplet, Moondrop is here with a special DSP single dynamic driver IEM, the Moondrop JIU. The JIU looks like a Moondrop CHU with a Type-C termination. Moondrop has actually taken the cavity structure and driver configuration of the Chu and further optimized its performance using DSP (Digital Signal Processing) technology for the JIU.

The Quarks DSP and Droplet have shown immersive potential in the industry, the optimizations done via DSP are promising quality upgrades and improved sound while being easy on the pocket. The Moondrop JIU benefits from a built-in DSP profile. Moondrop has optimized the sound performance with built-in SOC that helps create a balanced listening experience with a natural soundstage. The JIU is actually built on the Moondrop CHU with enhanced sound characteristics using DSP optimizations. The pair are said to have a pleasing lower-end response and a more natural soundstage presentation.

Moondrop has featured a 10mm high-performance dynamic driver unit on the JIU. It adopts PVD (Physical Vapour Deposition) technology to create a titanium-coated nano-crystalline diaphragm. It has an improved rigidity band and excellent damping characteristics. This benefits the pair in achieving improved treble response and details.

Moondrop has tuned the set using their famous VDSF target response curve. VDSF is a parametric target and is usually preferred by many audiophiles for its clear and crisp sound presentation. In order to match the desired target curve, Moondrop has designed a special cavity structure using FEA simulation and 3D printing technology. The shells are made up of high-quality zinc alloy material.

Moondrop JIU features a versatile USB Type-C termination. Nowadays 3.5mm audio jack is missing from most smartphones and this is where the Type-C termination comes in handy. You can use the JIU straight with your smartphones, laptops, and computers. It even has a built-in microphone for easy communication.
