Extend 3.5mm Audio Connections

This 25 ft stereo extension cable adds reach between any two devices that use a 3.5mm jack such as headphones, portable players, car stereos or PC audio outputs. The male-to-female layout lets you keep the original plug in place while routing the cable to a more convenient spot. Fully moulded connectors with nickel-plated contacts resist wear and maintain a clean signal path. A flexible black jacket eases installation behind desks or around corners.

Replacing Short Factory Cables

Many phones, tablets and laptops ship with cables under six feet which limit placement of speakers or headphones. This extension bridges that gap without introducing a second connection point that could loosen over time. The jump is worth it when the source device must stay fixed — such as a wall-mounted TV or a desktop tower — and the listening position is farther away than the stock lead allows. It also avoids the signal loss that can come from daisy-chaining multiple shorter cords.

Consistent Signal Over Long Runs

The 25 ft length is well within the range where an unbalanced 3.5mm stereo link remains noise-free for typical consumer gear. Nickel-plated contacts and a moulded strain relief keep contact resistance stable even after repeated plugging and unplugging. The flexible jacket prevents kinks that could degrade shielding when the cable is routed through tight spaces or moved occasionally. Under normal indoor use the cable delivers the same stereo fidelity at the far end as at the source.

Questions about this item

Will the 3.5mm stereo male connector on the 40409 fit into a standard 3.5mm audio jack on my laptop?

Yes, the 3.5mm stereo male plug is sized for the standard 3.5mm audio port found on laptops, phones, tablets and other devices listed in the compatibility notes.

How do I install the 25 ft extension cable without damaging the fully moulded connectors?

Route the flexible jacket along the desired path, then push each moulded connector straight into its port until it seats firmly; avoid twisting the plug body, which is the step most people get wrong.

When should I replace the cable if the nickel-plated contacts wear or the jacket frays?

Replace it when you hear static, intermittent sound or see exposed conductors, as the moulded strain relief and nickel plating are designed for long life but will degrade with heavy bending or corrosion over time.
