3.5mm to 2x RCA stereo audio cable
Cable length: 2m

Ideal for connecting your computers sound card, to or from your stereo/amplifier, VCR/TV(for audio only of course)
Every computer sound card I've seen has a 3.5mm socket for both audio output & input.

Can also be used for other purposes of course, for example connecting from your MP3 player to a stereo/amplifier.
Many portable audio devices have 3.5mm sockets, usually used for headphones/earphones.

Can also be used for any other audio devices that have standard 3.5mm audio sockets of course.
This excludes some minidisc player/recorder sockets, as some have a special 3.5mm socket that actually uses an optical signal(light shines through cable)
