Also: AirPods Pro might be an inexpensive solution to your hearing loss Cochlear implants are worn by people with inner ear hearing loss. For hearing people, sound waves enter the outer ear and then travel to the eardrum, where waves vibrate it. Then, the middle ear amplifies the sound and delivers it to the cochlea in the inner ear, where the signal is transmitted to the auditory nerve in the brain.  In people with damage to their inner ear, where the cochlea is, electrical signals made by the cochlea aren’t transmitted as efficiently. Cochlear implants receive sound waves directly from the middle ear and stimulate the auditory nerve, bypassing any impaired parts of the ear.  Also: The best bone conduction headphones (and how they work) The new feature is now available on compatible devices: Fire TVs in the Omni QLED series, Omni series, 4-series, and second and third-generation Fire TV Cube.
