If your Monster brand headphones are missing sound in 1 ear, this may be the fix you need.

This cable is for the Detox, Pro, or Mixr model only.  If your phones only work on the side that the cable plugs in, the wire

running through the headband is broke.  Getting these repaired is a major chore.  This cable plugs into both sides at the same time.

It is well made with high quality Mogami wire.  It is sleeved and heatshrink has been used for strength. 

Measures 4 1/2' in length.   Obviously the red colored wire goes in the right side of your headphones.
