In response to a listener input, the first audio signal and a second audio signal from the second source are output simultaneously on the first and second speakers. The first signal is output from each of the first and second speakers such that the first signal is perceived by a listener to originate from a first direction toward the listener. The second signal is output from each of the first and second speakers such that the second signal is perceived by the listener to originate from a second direction toward the listener. The second direction is offset at least ninety degrees from the first direction."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Menu navigation method for user of audio headphones","description":"A method of operating an audio system having first and second sources includes outputting a first audio signal from the first source on first and second speakers.
