The Pyle PLGI35T 3.5 mm/1/8" Stereo Audio Ground Loop Isolator eliminates the electrical noise and hum caused by ground loops with this ground loop isolator. These problems typically occur when multiple components receive power from different locations. This isolator solves that problem by providing ground path isolation between components while maintaining full frequency response. This device is designed to work with any music player that outputs stereo audio over a 3.5 mm jack. It provides a female-to-female 3.5 mm setup.
