  • “I was amazed at how quick and helpful it was to use my hearing aid app to customize my listening preference and choose how i wanted to hear my wife and young son, sitting in a booth at a crowded resturant. It was like I was able to just focus on their voices. To be able to change the sound just how I wanted to - was quick and easy...and it worked”

  • “I love my new hearing aids. Noisy and loud environments were very difficult for me. I finally feel engaged in noisy resturant situations. I can actually understand all the conversations going on around the table. Before i would just smile and nod to my friends that i could not understand. Social settings are so much more comfortable and relaxed for me when it is noisy and loud. Thank you,I feel like a new person and back to my old, fun self.”
