Paul is starting to lose his hearing and wants to know what hearing aid Leo uses. Leo says the interesting thing about today's hearing aids and in-ear monitors is that they work with a smart phone and he believes that they will become part of the "wearable computer" revolution.
Starkey makes the Halo that works with the iPhone, and there are several others as well. It can use the GPS of the phone to change the hearing settings automatically, which is cool. He can also listen to music or streaming media through them, as they do double duty as earphones. They're not cheap, though, and they aren't HiFi. Hearing aids still focus primarily on the vocal range.
