Most modern hearing aids use Bluetooth technology to connect directly to a smartphone allowing personalization through an app. Think about being able to adjust the volume of your hearing aids or switching programs without having to reach up behind your ear.
This technology also allows you to stream audio from your iPhone, iPad or iPod touch directly into you hearing aids. If you have a different smartphone, you can use a discreet wireless accessory to stream sound as well. Imagine taking a phone call and being able to hear the call clearly and directly into your ears!
