About this item This audio splitter cable is a handy adapter that lets you split the 3.5mm audio device such as iPad, iPod, MP3, CD player, computer sound card, or any mini-stereo audio device into 2 duplicated audio outputs for headphones, speakers, recorder, audio receiver, and more for expanded audio distribution. Two separate volume control dials for both audio outputs allow you to set the volume as loud or quiet as you want. With this stereo headphone splitter, simply plug in another pair of headphones and share the music between two people. One end features a male 3.5mm plug, and the two ends have 2 female 3.5mm jacks. Dimensions: 6 x 4 x 0.5 inches.
