For people using hearing aids equipped with a T-Coil, the iLoop neckloop works to amplify sounds coming from an audio device such as an MP3 player, iPod, or other device with a 3.5mm jack. Plug the iLoop into the headphone jack of the audio player, and receive up to 30dB of clear, amplified sound through the T-Coil, with no background noise.
Here is a video on how the iLoop works:
