Brings noteworthy improvements

Retains musicality true to the source

When we make TRN T4 cables, we use specialized high-temperature molds to draw copper into a long single-crystal structure, ensuring the content of the least possible oxide, as well as other impurities. Coupled with premium dielectrics and TRN's proprietary winding geometries result in fuller and more detailed sound that immerses the listener in the music.

Hand-woven to perfection

6N OCC copper that improves signal transmission quality encased in stretch-resistant polyurethane outer sleeve. Geometrically woven to reduce microphonics, nonetheless retaining flexibility and pliability for easy coiling.

Carbon-fiber encased insulator and gold-plated 3.5mm stereo jack

Specially-constructed progressive pressure-contact connector eliminates structure-borne and air-born noise, surface oxidation as well as magnetostriction.
Available in 3.5mm / 2.5mm and 4.4mm balanced gold-plated stereo jacks.

Non-magnetic alloy cable, Y-split, and chin-slider

Magnetism can be a friend or foe. However, when present in a cable, it strips away details, masks clarity, and causes veiled and muddy sound. It also leads to the loss of microdynamics and holographic imaging. Tonality becomes dull and unnatural. TRN makes absolutely sure all hardware is sourced from non-magnetic materials.

Red and blue indicator rings for an absolute foolproof connection

Use the "Blue" ring - for the left channel and the "Red" ring - for the right channel.
Available in 0.75mm/0.78mm/MMCX connectors.

Available In Balanced And Single-Ended Connectors
