• The nozzle of the CHU II consists of a separate brass CNC component, offering higher precision and density.
• CHU II incorporates a new generation of replaceable acoustic filters.
• CHU II was tuned by senior acoustic engineers and audiophiles with rich knowledge and wide experience, and exhibits an excellent frequency response curve in line with the VDSF Target Response.
• Ultra-low Nonlinear Distortion, Reproduction of Subtle Details.

Enhanced Sound with New-Generation Dynamic Driver

Moondrop has revamped the driver used in the original Chu IEMs, equipping the Chu II with a high-quality aluminum-magnesium alloy composite diaphragm dome and ultra-thin CCAW voice coil. This combination, along with the diaphragm's high rigidity and lightweight nature, delivers improved treble extensions and punchier bass response. The Chu II sets a new standard as the first budget IEM to incorporate an AL-Mg alloy composite diaphragm.

Anti-Oxidation Alloy Casted Shells

The Chu II retains the stylish design of its predecessor, featuring ear shells manufactured using Moondrop's advanced alloy casting technology. This manufacturing process ensures a robust and solid build structure with a refined textured finish. Additionally, the ergonomic shape of the ear shells guarantees a comfortable and secure fit, enhancing the overall listening experience.

CNC Machined Brass Acoustic Nozzle with Replaceable Mouth

The Chu II boasts a CNC machined brass acoustic nozzle, contributing to highly precise sound reproduction with a beautiful and rich tone. What's more, the filter at the mouth of the nozzle is replaceable, allowing users to easily swap it out if it gets damaged or blocked, ensuring uninterrupted audio performance.

Professional Tuning Adjustment

The Moondrop Chu II is meticulously tuned by experienced acoustic engineers and audiophiles with extensive knowledge and experience in the audio industry. It follows the VDSF target response, just like the OG model, but with the inclusion of a newer and higher-quality dome diaphragm, resulting in refined and richer sound reproduction compared to its predecessor.

Clear Sound with Ultra-Low Nonlinear Distortion

The Chu II offers an immersive listening experience with its clear and detailed sound reproduction. With non-linear full-frequency distortion measuring below 0.05%, the Chu II ensures high-quality output with a rich tone and exceptional separation, allowing listeners to hear every nuance and intricacy of their favorite music.

Detachable cable

The Moondrop Chu II provides users with the flexibility to customize their listening experience by allowing cable swapping. It utilizes standard 0.78mm two-pin connectors, enabling users to easily replace the included cable with their preferred upgrade cables or even switch to Bluetooth cables for added convenience. This versatility ensures compatibility with a wide range of cable options, empowering users to tailor their setup to their liking.
