3.5mm to 3.5mm Stereo Aux Cable

A basic 3.5mm (1/8") to 3.5mm stereo auxiliary cable — the cable that connects a phone, laptop, tablet, or any device with a headphone jack to a car stereo aux input, portable speaker, home stereo, or any system that accepts a 3.5mm input.

Why keep one (or three) on hand: Aux cables are inexpensive but get lost constantly — left in rental cars, borrowed by friends, broken at the connector. Worth keeping spares in the car, in a bag, and at the workstation.

Stock for: Anyone with a car aux input, podcasters connecting devices to recorders, students plugging laptops into classroom speakers, and as a low-cost add-on item alongside Bluetooth speakers and portable audio gear.
