Thanks for this link and the article. That said, you missed an important point. On Amazon, there are many (172) similar products at prices from $10 to $730. There is no need to go down the Sony path with this idea. Perhaps you could have tried the cheaper ones and told us if they are OK. In my house, we have a noisy dishwasher. I could see using this for about an hour a day. But, I don't see paying Sony prices for a $30 speaker.
