Apple has submitted a patent application for self-adjusting headphones.
The application describes potential technology that could deliver automatically adjusted sound according to the size of the user's ear and shape.
An electrical current, microphones and acoustic indicators could be used to measure how well the earbuds are sealed to the user's ears.
If the signals find the seal is imperfect, the headphones calculate an appropriate adjustment to the balance, EQ and noise cancelling settings.
Apple also mentions that it would alert users of the imperfect fit on their device, potentially so they can make any physical readjustments to achieve better sound.
Apple submitted the application in February to the US Patent & Trademark Office (UPTO), titled 'Electronic device and headset with speaker seal evaluation capabilities'.
