Don't know about Resound, but Oticon is little more than an extremely high priced amplifier. They promise the world, but deliver little more than a pebble. The ONLY thing that works as they claim is the connectivity. I can make phone calls on my iPhone and listen to music from my iPhone. Other than that, I hear nothing but noise, and very loud noise at that. On top of that, Oticon doesn't really care if their expensive amplifiers work as claimed. People First, not hardly. Money First - you bet.
