I’ve tried Phonak. Their implementation sucks. At least for my ears. Plus they are expensive and I had nothing but trouble with their reliability. Just my experience for my ears. Others like them.
For me, I found their algorithm for switching between situations (quiet, noise, etc) could never make up its mind. Worse, would get stuck in the wrong one and would have to be rebooted and reprogrammed. Maybe the new ones are better, but that experience left a bad taste in my mouth. Never again.<shrugs></shrugs>
