Three years later, the market has evolved dramatically. To meet current demands and usage scenarios, MOONDROP has leveraged its cutting-edge technology and hardware development capabilities to introduce the brand-new Quark2.\n\n\nLCP Dome Composite Flexible Suspension Dynamic-Driver Diaphragm\nThe Quark2 features a closed front cavity design for enhanced reliability and superior sound isolation. With the aid of advanced multi-physical field finite element simulation software, MOONDROP has refined the acoustic structure and optimized a 7.8mm dynamic driver specifically for this design. This configuration provides a pure-pressure soundstage and punchy bass that surpass typical limitations of small drivers. The driver incorporates an efficient N52 magnetic circuit and a lightweight CCAW drive coil for excellent energy conversion efficiency and response speed. The micro-dynamic driver with an LCP dome and flexible suspension diaphragm ensures an exceptional wide-band response and rich detail, backed by MOONDROP's expertise in superior acoustic performance.\n\n\n\nUniversal USB-C Interface Compatible with Windows, Android, and iOS\nBased on the standard UAC 2.0 audio protocol, the USB-C interface of the Quark2 is compatible with Windows PCs, Macs, Android phones, iPhones, iPads, and other devices with a standard USB-C port.\n\n\n\nRefined High-Level Tuning\nThe Quark2 offers an ultra-wide frequency response range, fine-tuned to the VDSF Target Response. It includes three preset tunings to cater to various listening preferences. The high-level configuration ensures exceptional acoustic performance, with full-link nonlinear distortion kept below 0.05%, thanks to the new audio SOC chip.\n\n\nWired Lossless Transmission Eliminates Latency Problems\nPerfect for Hi-Res music, shooting games, or music games, the wired connection ensures zero latency for a seamless experi","images":["https://cdn.shopify.com/s/files/1/0040/7201/3924/files/1_03c0b6a9-2b26-4e7d-81d0-a54d581f13ce.webp?v=1722589185","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/PHI_4483-_-NR.jpg?v=1723546651","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/PHI_2860.jpg?v=1723546651","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/PHI_2898.jpg?v=1723546651","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/PHI_2652-_-NR.jpg?v=1723546652","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/PHI_2738-_-NR_b23ea712-26f4-4506-bb7a-d90a4517c820.jpg?v=1723546652","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/PHI_2774-_-NR_9c03753b-9604-4b8d-8f49-ca11bff9d26d.jpg?v=1723546651","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/PHI_2819-_-NR.jpg?v=1723546651","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/PHI_2850.jpg?v=1723546652","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/PHI_2855_7df08c35-0e6d-49f0-8e83-2206c90c76e2.jpg?v=1723546652"],"price":19.99,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:45.940Z"},"share_url":"https://firestarter.network/l/lst_uTP3YzAH","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
