Just because your hearing is going doesn't mean your love of technology has to. Check out our helpful guide to smart phones that support the M4/T4 standards to ensure your calls are as clear as possible.
What does M4/T4 mean?
The M and T system refer to how the phone communicates with your hearing aid, with the quality represented by a number (higher is better.)
M(icrophone) means that the phone uses your hearing aid's microphone, with minimal interference from the phone's electronics.
T(elecoil) means that the phone transmits a magnetic signal to your hearing aid. This technology is also known as T-switch, T-coil and Telephone switch. This will generally be much clearer than Microphone, as your hearing aid will play the sound directly into your ear, without any extra noise or interference picked up when using the microphone.
