Headphones — Moondrop CHU

The Moondrop CHU is a wired in-ear headphone of closed design with a very high sensitivity rating. It is one of the budget in-ear models in Moondrop's large catalogue.

Key specs that matter

The rated frequency response runs from 10 Hz to 35 kHz, which is wide at the top end. Sensitivity is 120 dB per milliwatt and impedance is 28 ohms, so even a weak source signal reaches full volume.

Pairing

Since the impedance is low and the sensitivity high, a smartphone, a dongle DAC or a portable player drives the CHU directly, and no dedicated headphone amplifier is required.

Alternatives

The Moondrop Starfield II is a more expensive single-driver in-ear model with a lithium-magnesium alloy dome.
