* switch my hearing aids between 5 different programs depending on the environment.
* play "fractal" like tones to combat my tinnitus
* adjust the volume including muting the outside world
* play music from anything with a 3.5mm jack (bluetooth also available)
* hear calls from my phone
* probably more I'm forgetting
If it wasn't for the being hearing impaired part, having hearing aids is pretty cool :)
It looks like Bose is trying to bring this technology to a bigger market which is cool.
