The Mogami Gold 3.5 TRS Male to Dual XLR Male Y cable is the top choice for professional use. It's a high quality, 2 conductor cable with a split to a stereo audio at the 3.5 connector into 2 mono signals left and right at the XLR male connectors. This is great for the output of a portable media player such as a smartphone, laptop, tablet or any other similar media device with 3.5 output going in to a professional mixer or other source requiring XLR connection.
