All digital handsets have a rating for their ability to reduce interference with hearing aids operating in acoustic mode – from M1 to M4, with M4 being the best. Handsets are also rated – from T1 to T4 – for their ability to operate with hearing aids that contain a telecoil (a tightly wrapped piece of wire that converts sounds into electromagnetic signals) and operate in inductive coupling mode. The FCC considers mobile handsets to be hearing aid compatible if they are rated at least M3 for acoustic coupling and at least T3 for inductive coupling. Hearing-aid compatibility ratings aren’t a guarantee that a particular hearing aid works well with a particular phone; but the higher the rating, the more likely the handset will be compatible.

This phone has been tested and rated 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.
