First of all, the patent says that it can make headphones non-directional without ensuring that users put them in the right direction. The left earmuff is on the left ear and the right earmuff is on the right ear. The headphone can automatically detect the direction and adjust its output to match. In one embodiment, an automatic right ear detection system for headphones includes the same first and second earmuffs. Each of the first earmuffs and the second earmuffs includes five microphones. In one embodiment, when the first earmuff is worn on the user's right ear, the first microphone is located farther from the user's mouth and the second microphone is located closer to the user's mouth.

In other words, once the user speaks, the earphone can tell which microphone is closest to the user's mouth on each earphone, from which we can see how the earphone is worn. For example, Siri commands to play music can cause stereophonic channels to play through the correct ear muff. Secondly, the input from the microphone array can be used to separate voice from background noise (such as wind or traffic) and filter out the latter during telephone calls.

The processor can be used to perform voice beamforming to the user's mouth to capture the user's voice and perform noise beamforming far from the user's mouth to capture environmental noise. In February, the company said that Apple was in the process.DevelopmentHigh end earphone type earphone. This point was confirmed by a Bloomberg report in July, which said the product will be released next year.
