Activating hearing aid mode on your iPhone
To activate Hearing Aid Mode on iPhone 4 (GSM model) with iOS 5 or later, go to phone Settings, select General, then select Accessibility. Here you will see the Hearing Aids option.
Hearing Aid Mode on the iPhone 4 (GSM model) reduces the transmission power of the cellular radio in the GSM 1900 MHz band, which may result in decreased 2G cellular coverage.
To activate Hearing Aid mode on iPhone 5 or later, go to Settings > General > Accessibility. Hearing Aid mode on the iPhone 5 modifies the phone’s acoustic settings to improve compatibility with hearing aids set in “T” or telecoil mode.

Ensuring the best experience with a hearing aid
iPhone and hearing aids generally work best together in “M” or acoustic coupling mode. To use your hearing aid in this mode, make sure that your hearing aid is set to “M,” or acoustic coupling mode, and position the iPhone receiver near the hearing aid’s built-in microphone (or microphones). In other words, hold your iPhone against your head as you would naturally hold the phone when making a telephone call. The hearing aid will receive audio from the iPhone through its built-in microphones. For the best results, try using the iPhone in different positions relative to your hearing aid—for example, placing the receiver slightly above the ear may result in better performance for hearing aids with microphones positioned behind the ear. If you have an iPhone 4 (GSM model), activate Hearing Aid Mode
If Acoustic Coupling does not produce a satisfactory result, try using your hearing aid in “T,” or telecoil coupling mode. To use your hearing aid in this mode, make sure that your hearing aid is set to “T,” or telecoil coupling mode (not all hearing aids have this mode). If you have an iPhone 5 or later, activate Hearing Aid Mode. Your healthcare provider may assist you in determining if your hearing aid will be most compatible with your iPhone.
