Hearing Aid-Compatible Phones
Cell phones are rated according to their hearing aid compatibility in terms of RF transmissions or telecoiling coupling capability. Cell phones using acoustic coupling technology are tested for reduced RF emissions according to the ANSI C63.19 standard. Those that are considered passing (those with a rating of "good" or "excellent") for use with hearing aids set in microphone mode are assigned a rating of M3 or M4. Cell phones using inductive coupling technology are tested for telecoil coupling capability according to the ANSI C63.19 standard. Those that are considered passing (those with a rating of "good" or "excellent") for use with hearing aids set in telecoil mode are assigned a rating of T3 or T4. The higher the "M" or "T" rating, the less likely the hearing aid user will experience interference while using a cell phone.
Straight Talk Wireless currently offers the following hearing aid-compatible handsets/phones. All these handsets are rated at M3, T3 or better. Although prices for the handsets may vary, all these handsets offer the same level of functionality by providing each end user with access to voice and text services.
