Some phones are measured for compatibility with 
hearing aids.  If the box for your particular model has 
“Rated for Hearing Aids” printed on it, the following 
explanation applies. When some mobile phones are used 
near some hearing devices (hearing aids and cochlear 
implants), users may detect a buzzing, humming, or 
whining noise. Some hearing devices are more immune 
than others to this interference noise, and phones also 
vary in the amount of interference they generate.  The 
wireless telephone industry has developed ratings for 
some of their mobile phones, to assist hearing device 
users in finding phones that may be compatible with their 
hearing devices. Not all phones have been rated. Phones 
that are rated have the rating on their box or a label on 
the box. The ratings are not guarantees. Results will 
vary depending on the user’s hearing device and hearing 
loss. If your hearing device happens to be vulnerable to 
interference, you may not be able to use a rated phone 
successfully. Trying out the phone with your hearing 
device is the best way to evaluate it for your personal 
needs.
