We talked with Tom Powers of Siemens at the TPN CES live broadcast. Siemens has come out with the Minitech app that will work with tablet or smartphone so they can focus what they are listening to.
What looks like regular hearing aids, these devices are bluetooth connected so you can use your phone (as a hands free device), a lavaliere microphone with attenuation to adjust sound, or sound from their TV or another device.
If you need to talk with someone while your music is playing, simply press a button on the aid and talk with those who approach.
