HCP 6.3

T+A offers a selection of three different headphone cables. One of them is equipped with the 6.35 mm barrel connection type. The “jack” is regarded as the most popular and frequent connector to date. However, this design is not symmetrical as the left and right channel are not separated. The HCP 6.3 headphone cable is available in 3m and 5m lengths.


Designing headphone cables is a completely different engineering task than designing speaker cables. Speaker cables have to deal with high currents and voltages, while headphones do the exact opposite: they work with lower currents and voltages. High quality materials and carefully meticulous design processes are prerequisites for making refined and accurate sounding headphone cables. We use pure OFC (Oxygen Free Copper) as a base and coat the conductors with pure silver. The impedance, capacity as well as inductance are low, and above all (are designed to offer) extraordinarily linear and constant characteristics over the entire frequency range.

The left and right channels are separated, and each is constructed out of two signal cables (symmetrical design). Additionally, both are covered by a silver-plated shielding braid to prevent electrostatic charging and electromagnetic influences. The insulation is made of high-quality dielectric materials. Professional two-pin connections (plug and socket) are used on the headphone side.
