recommend to use a customized earmold.

Mobile phone compatibility rating
Some hearing aid users have reported a buzzing
sound in their hearing aids when they are using
mobile phones, indicating that the mobile
phone and hearing aid may not be compatible.
According to the ANSI C63.19 standard (ANSI
C63.19-2011 American National Standard
Methods of Measurement of Compatibility
Between Wireless Communications Devices and
Hearing Aids), the compatibility of a particular
hearing aid and mobile phone can be predicted
by adding the rating for the hearing aid immunity
to the rating for the mobile phone emissions.
For example, the sum of the hearing aid rating
of 4 (M4) and a telephone rating of 3 (M3) would
result in a combined rating of 7. Any combined
rating that equals at least 5 would provide
"normal use"; a combined rating of 6 or greater
would indicate "excellent performance. "
The immunity of this hearing aid is at least
M4. The equipment performance measurements,
categories and system classifications are based
upon the best information available but cannot
guarantee that all users will be satisfied.
