AudioQuest USB-A Noise-Stopper Caps Fit Right Over the Unused USB Inputs and Outputs of Your Gear: Simple, Inexpensive Devices Block Noise from Entering Active Circuit and Protect Against Dust
Prevent RFI and EMI noise from entering the active circuit of the unused USB-A inputs and outputs on your audio/video gear with AudioQuest USB-A noise-stopper caps. A simple, easy, effective, and cheap upgrade, these caps fit right over the unused ins/outs and also protect against dust and corrosion.
AudioQuest's RCA noise-blocking caps have been in use for decades. These apply the same concept to USB-A ins/outs. If you have gear or components with unused USB slots, consider these caps as essential as a power cord. You'll hear (and see) the difference! (Sold in sets of four.)
