When I first set it up all I could get was static; fortunately unplugging both cords from the base stand for ~15 seconds reset the thing and restored function. It works well enough now, allowing me to hear dialog much more clearly than with the unaided ear.I've only had it for a day now, and the biggest issue I have is the cost of replacement batteries. They're said to last 1-2 years and replacements are only sold attached to a complete replacement front plate for the astronomical total of $20/. This is something they don't go out of their way to make clear, but it's an unpleasant surprise in store for the unsuspecting consumer. I'm seriously considering taking mine back to Costco where the 2.3 is sold for $39.95 and looking for something that uses more reasonably priced consumables.
