This product is working really well for my wife. As expected - and as noted by the seller -there is a period of adjustment to the device (usually three weeks or so) while your ears become accustomed to it, and we are just at the start of that period. However, we're really impressed so far:
- The sound amplification is dramatic, and there is little feedback or "screeching". Before using them, she couldn't hear the television when it was turned up as high as possible, and now has asked me to turn the TV volume down since beginning use of the amplifiers.
- The units are easy to place in the ears, and they're very inconspicuous when worn.
- Possibly most important, Neosonic customer service has been highly responsive. I had a question about cleaning the units, and the video they provided didn't answer it. Kevin, the customer service representative, worked with me to resolve it. I wasn't sure how well the seller would support this product after purchase, but I didn't need to be.
Again, we're just beginning to use these, but I'm greatly encouraged by what's happened so far and confident it'll continue.
