Do these speakers have an auxillary jack?
Are these equipped with an auxillary jack to plug straight into a cd player?
These speakers do not have an auxiliary jack. They have two poles (- and +) that are intended to be connected via speaker wire to a stereo to a receiver. Also, note that they are not powered with an external power source (e.g. cord or batteries) so they wouldn't be able to amplify the sound coming directly from a CD or MP3 player.
