This implant enables the deaf to hear music

Hearing implants can now stream phone calls and music to the deaf after a breakthrough in wireless technology from Apple.
Apple and Cochlear, which makes medical devices, have developed the first cochlear implant that can stream direct from a smartphone. This will allow people with severe hearing loss to hear calls and listen to music and audiobooks clearly.
Cochlear implants work differently from hearing aids as they replace the usual hearing mechanism rather than simply making sound louder. They are made up of an internal part that is implanted in the mastoid bone behind the ear to stimulate the hearing nerve directly and an external microphone and sound-processor.
The new Cochlear implant uses Apple’s Bluetooth low-energy audio technology to stream from iPhones without draining the implant’s battery too quickly.
Apple will make the streaming technology available to other manufacturers besides Cochlear.
