{"type":"firestarter.listing","listing":{"id":"lst_3z3ftVL7","product_name":"Moondrop Marigold USB-C Neckband-Style IEMs","category":"Earphone / In-Ear Monitor (IEM)","description":"A classic design reborn with modern tech\nThe Moondrop Marigold is a neckband-style USB-C in-ear earphone that revives the once-common asymmetric cable design while introducing a beryllium-plated dome driver, a built-in 32bit/384kHz sound card, and hardware-level AI noise canceling. \n\nBeryllium-plated driver for rich, dynamic sound\n\nAt the heart of the Marigold is a 10mm dynamic driver with a beryllium-plated dome composite diaphragm. Paired with an N52 magnet and a dual-cavity brass housing, it achieves distortion as low as 0.05% while delivering wide-band performance. The result is high-resolution playback with the kind of clarity, punch, and fullness that makes you forget you’re wearing a neckband at all.\n\nBuilt-in USB sound card\n\nForget the dongles. The Marigold includes its own USB-C sound card capable of 32bit/384kHz decoding. That means you can plug directly into most modern smartphones, tablets, and computers and immediately stream master-grade audio. It’s plug-and-play, with no drivers needed.\n\nAI-powered noise canceling for calls\n\nA hardware-level NPU runs advanced AI algorithms to reduce background noise and enhance vocal clarity. Whether you’re on a call in traffic or chatting mid-game, your voice cuts through cleanly. The MEMS microphone ensures pickup is natural and detailed.\n\nClassic asymmetric cable design\n\nThe asymmetric cable design was once a staple of Walkman-era earphones. It lets the cord drape naturally around your neck when not in use—no case required, no fumbling with wires. The Marigold revives this feature, pairing it with modern audio performance for a balance of convenience and character.\n\nCustom tuning with DSP\n\nThe Marigold includes a second-generation DSP accessible through the Moondrop app (Android only) or via a professional web tool. Adjust filter types, frequency points, gain, and Q values with precision. Real-time frequency response graphs help guide your tuning, and one-button EQ settings let you jump between presets with ease.\n\n","images":["https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-moondrop-earphone-in-ear-monitor-iem-moondrop-marigold-usb-c-neckband-style-iems-1193150828.jpg?v=1758047092","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-moondrop-earphone-in-ear-monitor-iem-moondrop-marigold-usb-c-neckband-style-iems-1193150827.jpg?v=1758047090","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-moondrop-earphone-in-ear-monitor-iem-moondrop-marigold-usb-c-neckband-style-iems-1193150826.jpg?v=1758047086","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-moondrop-earphone-in-ear-monitor-iem-moondrop-marigold-usb-c-neckband-style-iems-1193150825.jpg?v=1758047083","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-moondrop-earphone-in-ear-monitor-iem-moondrop-marigold-usb-c-neckband-style-iems-1193150824.jpg?v=1758047080","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-moondrop-earphone-in-ear-monitor-iem-moondrop-marigold-usb-c-neckband-style-iems-1193150823.jpg?v=1758047077","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-moondrop-earphone-in-ear-monitor-iem-moondrop-marigold-usb-c-neckband-style-iems-1193150822.jpg?v=1758046975","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-moondrop-earphone-in-ear-monitor-iem-moondrop-marigold-usb-c-neckband-style-iems-1193150821.jpg?v=1758046972","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-moondrop-earphone-in-ear-monitor-iem-moondrop-marigold-usb-c-neckband-style-iems-1193150820.jpg?v=1758046969","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-moondrop-earphone-in-ear-monitor-iem-moondrop-marigold-usb-c-neckband-style-iems-1193150819.jpg?v=1758046966","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-moondrop-earphone-in-ear-monitor-iem-moondrop-marigold-usb-c-neckband-style-iems-1193150818.jpg?v=1758046963","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-moondrop-earphone-in-ear-monitor-iem-moondrop-marigold-usb-c-neckband-style-iems-1193150817.jpg?v=1758046961","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-moondrop-earphone-in-ear-monitor-iem-moondrop-marigold-usb-c-neckband-style-iems-1193150816.jpg?v=1758046957","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-moondrop-earphone-in-ear-monitor-iem-moondrop-marigold-usb-c-neckband-style-iems-1193191295.jpg?v=1758061357"],"price":39.99,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:25:57.313Z"},"share_url":"https://firestarter.network/l/lst_3z3ftVL7","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
