{"type":"firestarter.listing","listing":{"id":"lst_IIQBeyE6","product_name":"DDHIFI M198C","category":"Audio Cable","description":"\n\nPrecision Sound Tuning with HiFi Intentions\nPart of DDHIFI’s Memory Series, the M198C refines the design principles of the M110C to deliver a more HiFi-centric listening experience. With both the DSP tuning and OCC cable optimized for clarity and balance, this cable offers an ultra-clean background and lifelike audio reproduction for critical listening.\n\n\nCS43198 DAC with High-Res Decoding\nAt the heart of the M198C lies the CS43198 DAC chip, supporting PCM up to 384kHz/32bit and native DSD256 decoding. Paired with a high-performance USB audio bridge chip, it ensures accurate digital-to-analog conversion and supports in-line controls and microphone functionality with excellent signal integrity.\n\n\nCustom 5N OCC Upgrade Cable\nThe M198C inherits the wire architecture of DDHIFI's flagship Nyx Net cable. It uses high-purity 5N OCC copper, braided for stability and softness. The nylon-braided jacket is both durable and supple, balancing performance and portability for daily use or professional monitoring.\n\n\nDurable CNC-Machined Components\nEvery major hardware piece—the USB plug, Y-split, and earphone connectors—is CNC-machined from solid aluminum alloy. This not only adds rugged durability, but also offers better shielding and a sleek, cohesive aesthetic.\n\n\nProfessional-Grade In-line Microphone\nThe splitter integrates a high-quality silicon MEMS mic and separate left/right OCC shielding cables for improved anti-interference. It supports calls, gaming, livestreams, and voice recording with excellent clarity and minimal crosstalk or ground loop noise.\n\n\nCompatible Connector Options\nDesigned for ear-hook style IEMs, the M198C is available in both standard 0.78mm 2-pin and expanded MMCX connectors—compatible with recessed MMCX earphones like the Sennheiser IE900 and Sony IER series.\n\n","images":["https://cdn.shopify.com/s/files/1/0040/7201/3924/files/M198C-MMCX-02.jpg?v=1752807278","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/M198C-06.jpg?v=1752807278","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/M198C-07.jpg?v=1752807278","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/M198C-08.jpg?v=1752807278","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/M198C-09.jpg?v=1752807278","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/M198C-10.jpg?v=1752807278","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/M198C-11.jpg?v=1752807278","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/M198C-2pin-02.jpg?v=1752807278","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/M198C-03.jpg?v=1752807278","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/M198C-04.jpg?v=1752807278","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/M198C-05.jpg?v=1752807278"],"price":109.99,"currency":"USD","in_stock":true,"inventory_qty":19998,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:44.818Z"},"share_url":"https://firestarter.network/l/lst_IIQBeyE6","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
