Hearing Aid Compatibility (HAC)—U.S. only
iPhone is hearing aid compatible as determined by ANSI C63.19-2011. This
standard has two ratings: M (for reduced radio-frequency interference to
enable acoustic coupling) and T (for inductive coupling with hearing aids
operating in telecoil mode) on a scale from 1-4, where 4 is most compatible.
This iPhone is rated M3/T4. Note: the 2019 ANSI C63.19 standard does not use
this rating system nor do any test standards exist for any wireless technologies
that transmit above 6 GHz. Therefore, 5G NR mmWave frequency bands
cannot be tested.
Compulsory FCC statement: This phone has been tested and certified for use
with hearing aids for some of the wireless technologies that it uses. However,
there may be some newer wireless technologies used in this phone that have
not been tested yet for use with hearing aids. It is important to try the different
features of this phone thoroughly and in different locations, using your hearing
aid or cochlear implant, to determine if you hear any interfering noise. Consult
your service provider or the manufacturer of this phone for information on
hearing aid compatibility. If you have questions about return or exchange
policies, consult your service provider or phone retailer.
