A listing of current model phones that meet the acoustic (M3 or M4) and/or telecoil (T3 or T4) standards for hearing aid compatibility, as per the carrier websites, are listed below. These standards are intended to reduce interference between the cell phone and a hearing aid. However, having a rated phone does not guarantee that it will work without interference. The various hearing aid compatible classifications are listed to the right, from least to most compatible. Choose one of these to see all phones meeting or exceeding that standard. To see a cell phone's exact rating, use the Compare feature.
