Head Shadow is a hearing aid iPhone app for people with single-sided deafness or mild hearing loss in both ears. The app captures nearby sound with the iPhone or AirPods microphone, enhances it with a 10-band equalizer, and plays it in real time through wired headphones, AirPods, or AirPods Pro. FOR SINGLE-SIDED DEAFNESS When using AirPods, activate the microphone on your deaf side. Place that AirPod in your deaf ear and the other AirPod in your hearing ear. Head Shadow captures sound from your deaf side, enhances it, and plays it in your hearing ear, providing a CROS-like listening experience. FOR MILD HEARING LOSS If you have mild hearing loss in both ears, connect your wired or wireless headphones and play the app. Head Shadow captures sound with the iPhone microphone, enhances it, and plays it through your headphones. SOUND CONTROLS The 10-band equalizer lets you adjust the frequencies used in a standard audiogram. Reverb options let you hear how sound changes in different spaces.
