Ethereal is a pioneer in HDMI® cable technology, power distribution products, premium audio cable design, and AV integration. The company was originally conceived as Ethereal Home Theater in 2001. Our parent company, Metra Electronics, has been in business for more than 75 years and tapped into its expertise in car audio connectivity to create this separate entity, specifically for HDMI products and home theater systems.
