I've only been using the Phonak Audeo P90-R hearing aids for a few days but I've spent a lot of time playing around with the options.  I'm about to turn 72 in a couple of months. My left ear hearing is still very good but my right ear is only about 60% of that although word recognition is still very good from it. I hope that the hearing aid industry at least comes near catching up with the audio industry in the area of In-Ear Monitors which would greatly improve the hearing solution options.  I hope to see that soon.
