An Ultra High Speed HDMI cable certified for eARC, carrying lossless Dolby TrueHD and DTS-HD MA audio from the TV back to a soundbar or AV receiver over a single HDMI link.
Enhanced Audio Return Channel support distinguishes this Ultra High Speed HDMI 2.1 cable, letting a television send lossless Dolby TrueHD and DTS-HD Master Audio back to a soundbar or AV receiver over a single HDMI link. The eARC channel needs the full 48 Gbps certified bandwidth to carry uncompressed multichannel formats, including object-based Dolby Atmos passthrough. Because it is a standard Ultra High Speed cable, it also handles 8K at 60 Hz video in the forward direction. A 3-meter run suits most equipment-rack-to-television distances. It is used chiefly for audio return between a TV and receiver rather than as a primary source cable. Retail pricing falls between $12 and $30.
