Silver-Plated Copper IEM Cable (MMCX, 2.5 mm Balanced)

Four-core silver-plated copper IEM cable. The OFC copper substrate carries the audio current; the silver plating on the outer surface carries the high-frequency skin-effect component. Result: copper warmth in the bass and midrange, silver clarity in the treble — without the full silver-cable price.

MMCX-terminated at the IEM end; 2.5 mm TRRS balanced at the source end. For the modern 4.4 mm equivalent see the OCC copper 4.4 mm cable; for adapting this cable to 4.4 mm see the 2.5 → 4.4 mm adapter.

Pairs naturally with the Multi-BA IEM whose treble extension benefits from the silver-skin-effect path.
