Phones measuring an M3 or M4 cause less electromagnetic interference (EMI) and radio frequency (RF) interference, which should improve usability with hearing devices. However performance cannot be guaranteed since other factors, such as type of hearing device or degree of hearing loss, determine whether the phone will work well for a particular user.
