Precision Sound Tuning with HiFi Intentions

Part 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.

CS43198 DAC with High-Res Decoding

At 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.

Custom 5N OCC Upgrade Cable

The 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.

Durable CNC-Machined Components

Every 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.

Professional-Grade In-line Microphone

The 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.

Compatible Connector Options

Designed 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.
