Moondrop's Marigold is a cabled in-canal model that ends in a USB-C plug instead of an analogue jack, with the converter, microphone processing and tuning controls built into the cable. It launched on 10 September 2025 at USD 39.99. The lead follows an asymmetric neckband layout, and the earpieces are designed to be worn hanging straight down rather than looped over the ear.
Key specs that matter
Behind each nozzle is a 10 mm dynamic driver in a dual-cavity arrangement, with a beryllium-plated dome on a composite diaphragm with a flexible suspension edge and an N52 magnet behind it. Impedance is 32 ohm at 1 kHz, with a tolerance of 15 percent. Moondrop gives an effective frequency response of 20 Hz to 20 kHz at minus 3 dB on an IEC 60318-4 coupler, and a THD rating of 0.5 percent or less at 1 kHz and 94 dB, while its marketing material cites distortion as low as 0.05 percent. The built-in decoder handles PCM up to 32 bit and 384 kHz. A three-button remote sits on the cable.
Engineering and use context
Brass cavities hold the drivers, and the response is voiced to the VDSF curve the company applies to much of its range. Because the sound card sits in the USB-C plug, the earphones work with most phones and tablets that have a USB-C port and need no driver installation. A MEMS microphone feeds a hardware NPU chip that runs an AI vocal processing algorithm to strip environmental noise from calls and in-game chat. The DSP is Moondrop's second generation, adjusted through the MOONDROP app, where a graphical parametric equaliser exposes the filter type, centre frequency, gain and Q value of each band and lets users share their profiles with other owners through a community section.
Pairing
Any phone, tablet or computer fitted with USB-C can feed the Marigold a digital stream, and because conversion and amplification take place inside the cable, the analogue headphone output of the host device, if it has one, is not used at all. The fixed USB-C termination also means the earphone cannot be plugged into an external DAC or a portable player that offers only a 3.5 mm or 4.4 mm socket. The combination of an in-line remote, a noise-suppressing call microphone and a high-resolution decoder makes the model aimed at buyers who want one pair for music, voice calls and gaming from a phone without a headphone jack.
Alternatives
Moondrop's catalogue also lists the JIU as a DSP in-ear monitor for those wanting another wired model with processing built in.
