The AudioQuest RJ45 Noise-Stopper Caps are protective inserts designed to cover unused RJ45 Ethernet inputs or outputs on audio, video, and network components. By sealing open ports, they help reduce the ingress of radio-frequency interference (RFI) and electromagnetic interference (EMI), which can degrade system performance in sensitive digital and audio setups.
In addition to noise reduction benefits, the caps also provide physical protection by preventing dust, debris, and corrosion from accumulating in unused network ports. This helps maintain long-term reliability and connection integrity in professional and home audio/video systems.
Compact and easy to install, the Noise-Stopper Caps are a simple accessory designed to support cleaner system performance and better environmental protection for unused Ethernet connections.
