InLine Headphone extension cable 6.3mm Stereo M/F, gold plated, black, 3m

The InLine Headphone extension cable 6.3mm InLine 99973 is a 3 m black audio extension lead designed to extend a 6.35 mm (6.3 mm) headphone or audio connection. It features a 6.35mm male plug to a 6.35mm female socket with gold-plated contacts to maintain reliable signal transfer and reduce contact corrosion. The flexible jacket and modest diameter allow easy routing in studio, stage or home audio setups without adding significant bulk.

Advantages

Gold-plated contacts help ensure consistent conductivity and improved resistance to oxidation. The 3 m length balances reach and manageable cable handling, while the black outer sheath delivers a neutral appearance that fits professional and domestic environments.
