4 ft stereo extension for 3.5 mm ports

This male to female auxiliary cable extends any 3.5 mm jack by four feet. It suits listeners who need extra reach between a source device and wired headphones or powered speakers. The 120 cm length adds flexibility for desktop or portable setups without requiring a longer integrated cord.

Passive copper cable draws no power

The extension is a passive copper assembly, so it consumes no power and introduces no active electronics that could generate heat or hiss. Signal quality depends on the source and headphone combination rather than the cable itself. It is not suited for runs that exceed the four foot length or for balanced professional audio connections.

Questions about this item

How do I install the 3.5mm male-to-female extension cable correctly, and what step do people often get wrong?

Plug the male 3.5 mm connector fully into your source device and the headphone plug fully into the female jack; the common mistake is leaving either end partially seated, which causes intermittent sound.

What maintenance or replacement will the 4 ft auxiliary extension cord need later?

Inspect the 3.5 mm plugs and the cable jacket periodically; replace the cord if the connectors become loose, the insulation cracks, or audio cuts out when the cable is moved.
