Use these 3.5 mm TRS stereo male to RJ45 female adapters to transmit stereo audio over existing Ethernet cabling as a practical way to extend audio connections across longer distances. Each adapter is 8 in (0.7 ft) and features a 3.5 mm TRS stereo male plug on one end and an RJ45 female socket on the other, compatible with CAT5 or CAT6 UTP (twisted pair) cable with RJ45 connectors. Plug-and-play operation makes setup simple: connect the 3.5 mm end to a source device, run your CAT5/CAT6 cable between locations, then use a second adapter at the far end to convert back to a 3.5 mm connection. Designed for compact, durable everyday use, it is compatible with stereo amplifiers, speakers, touch devices, song decks, and KTV touch screens in home theater, commercial audio, and multi-room AV routing setups.
