QED Performance 6.35mm Headphone Extension Cable 5m

The QED Performance 6.35mm Headphone Extension Cable is designed for listeners who need to extend the reach of their headphones without compromising audio quality. Available in three lengths — 1.5m, 3m, and 5m — it sits within QED's Performance range, positioned below the higher-tier Reference and Signature series.

Conductors

At the core of the Performance Headphone Extension are 99.999% oxygen-free copper (OFC) conductors, providing a low-resistance audio path that preserves detail and dynamics across the full cable length. The conductor geometry is engineered specifically to minimise crosstalk between the left and right audio channels, with the signal return path optimised to reduce inter-channel interference — a critical consideration for headphone cables where channel separation directly affects stereo imaging.

Connectors & Build

Both ends are terminated with gold-plated, close-tolerance 6.35mm stereo jack connectors. The cable has a 6mm outer diameter and is finished in QED's ergonomic soft PVC graphite jacket, which has been specially formulated to maintain flexibility and a quality feel in use.

Performance Range

The Performance series represents QED's mid-to-entry tier, sitting below the Reference and Signature cable lines in the company's range. It is a natural choice for listeners who have invested in quality headphones and amplification and want a cable that will not become a weak link in the chain. All QED cables carry the company's lifetime guarantee.
