AudioQuest HDMI cables are manufactured to exacting standards and are subject to rigorous quality control. However, if your HDMI cable has a real manufacturing defect, AudioQuest’s non-transferable original-owner limited lifetime warranty has you covered for cable purchased through an authorized AudioQuest US dealer. At its option, AudioQuest will repair or replace any defective HDMI cable that has not been abused, for the lifetime of the product. Proof of original purchase is required. This warranty is not an upgrade program for AudioQuest HDMI cables that were designed to meet previous generations of HDMI specifications. Current AudioQuest models are designed to meet HDMI 2.0 (18Gbps) or HDMI 2.1 (48Gbps). All generations of HDMI cable will provide some, but not all, of the features made possible by HDMI 2.0 and 2.1. All generations of HDMI cable are backwards compatible – they provide all the capabilities of previous generations. To experience the audio/video benefits made possible by the latest HDMI 2.1 hardware, an HDMI cable must meet HDMI specifications, specifically an FRL-enabled bandwidth of 48Gbps. Whether using HDMI-enabled gear with Standard Speed, High Speed (10.2Gbps), 18Gbps, or Ultra High Speed (48Gbps), AudioQuest’s HDMI “48” Series provide superior sound and a superior experience vs. even AudioQuest 18Gbps cables. This warranty is valid in the United States only. For warranty policies in other countries, please contact your local dealer or distributor.
