Moondrop CHU 10mm Dynamic IEM

The Moondrop CHU is an in-ear monitor built around a 10mm dynamic driver with a titanium-coated diaphragm and N52 neodymium magnet. An ultra-fine 0.035mm CCAW voice coil and patented anti-blocking acoustic filter complete the acoustic package. It is intended for listeners who want a single-driver IEM tuned to a published target curve.

Suited to critical listening on portable sources

The 28 ohm impedance and 120dB/Vrms sensitivity allow adequate volume from smartphone headphone outputs and laptop ports. Buyers who require a balanced cable connection, detachable cable system or multi-driver hybrid architecture should consider other models. The fixed cable and single dynamic driver limit configuration flexibility for specialised studio monitoring chains.

10mm driver with 20Hz-20kHz effective response

The effective frequency response spans 20Hz to 20kHz per IEC60318-4 at -3dB, while the wider measurement range reaches 10Hz to 35kHz under EC61094 free-field conditions. This single specification defines the usable bandwidth for music reproduction and determines whether the IEM matches the listener's tonal expectations.

Questions about this item

How much power will the 28 ohm impedance draw from my phone or dongle all day?

At 28 ohms and 120 dB/Vrms sensitivity the CHU reaches loud volumes with very little voltage, so a standard phone headphone jack or portable dongle can drive it continuously without draining the battery quickly.

Will the metal cavity get hot or the cable noise become distracting during hours of listening?

The zinc-alloy shell stays near ambient temperature because the 10 mm dynamic driver runs efficiently, and the lightweight cable transmits minimal microphonics when worn over-ear.

What source connector must my device already have for the inline microphone and remote to function?

The included cable terminates in a standard TRRS jack, so the host needs a single 4-pole socket that carries both stereo audio and microphone signals.
