The iSilencer+ 3.0 USB isolator from iFi Audio is a very effective method to eliminate the constant background noise and distortion that is common with USB audio components. The function of this device is in its name, to silence your equipment so you can enjoy your music and films free from noise free. Insert the iSilencer+ 3.0 into a USB port of your computer and it starts to work, just like that. Your music will sound so much clearer, you will notice the finer details and the bass and transparency will be improved significantly.
