I have a single sided loss. I started out with a single aid and it was great in quiet, but in a noisy restaurant, I had to remove it because the noise from that side was overwhelming and I could barely hear the speech from people at my table. I switched to two Phonak aids. HUGE difference!
Having a program with AmpCROS is the best of both worlds. I couldn’t find anyone where I live who could do it, so I had to resort to DIY. I only use that program when I need it because it drains the battery more quickly. If you have a pro who is suggesting it, I highly recommend it.
I had roaring tinnitus in the ear with the loss and wearing an aid in that ear brought it down so I only notice it when I’m thinking about it. It took awhile though.
