MOONDROP CHU II — Wired IEM Dynamic Driver In-Ear

The audiophile community called it the end-game of entry-level IEMs. At $31 for the base version, that's a bold claim — but the CHU II backs it up with hardware you don't usually see at this price: an aluminum-magnesium alloy composite diaphragm, brass CNC acoustic nozzle, and a tuning curve based on MOONDROP's VDSF target response. If you've been using whatever earbuds came in the box, this is the jump that actually matters.

What you get:

• 10mm dynamic driver with Al-Mg alloy composite diaphragm — aluminum-magnesium alloy dome dampens unwanted resonance and delivers fast transient response. The kind of driver material you find in headphones costing 3–5x more.
• Brass CNC acoustic nozzle — machined separately for higher density and precision. Contributes directly to tighter timbre and cleaner high-frequency detail versus plastic nozzle designs.
• 0.78mm-2pin interchangeable cable — universal standard. Swap to a balanced cable, a Bluetooth neckband (LITTLEWHITE), a TWS ear-hook adapter, or a portable amp cable (Moonriver2) depending on your setup. The IEM itself stays the same.
• Replaceable acoustic filters — tune the sound profile slightly or replace worn filters over time. Extends the lifespan and lets you adjust the sound to taste.
• VDSF-tuned frequency response — 15Hz–38kHz full range, tuned by MOONDROP's engineers to the diffuse-field preference curve. 119dB sensitivity means it gets loud easily off a phone with no amp required.

Heads up: this is a wired IEM — 3.5mm single-ended plug. No Bluetooth built in. If you want wireless, grab the bundle with the LITTLEWHITE neckband or the CDSP variant. The smartphone, Bluetooth cable, and DAC/AMP shown in product images are not included in the base version.

Bundle options available: CHU II solo / CHU II + MC1 microphone cable / CHU II + CDSP DSP cable / CHU II DSP version.

Perfect for: First serious IEM upgrade, audiophiles on a budget, late-night listening sessions at the desk, anyone who wants real sound quality without spending $150+.
