A PAIR OF INSIGNIA POWERED SPEAKERS COLOR BLACK

  I know almost nothing about these speakers except for the fact I tested them on my computer and they work.  They are 6 3/4 inches high, 2 1/2 inches wide and 3 1/8 inches deep.  They have a 4 feet cord connecting them together and use a standard 3.5mm RCA jack to connect to the computer.  They only have a power on button and volume control.  THEY ARE WIRED SPEAKERS!
