Yes, it's true the people with problems complain. Why not? It makes sense? But in all honesty, I don't agree that only the people with problems post reviews online.
Example:
I have a set of Etymotic ER6i headphones, and as I writes this, 201 people have reviewed them on Amazon.com with an average of 4 stars out of 5. The positives far outweigh the negatives. If only the so-called squeaky wheels bothered to file online reviews, then every product that garners any reviews would be deemed lousy.
No, when a product works as advertised and makes people happy they will report it just as much as someone with a problem. And that blows a major hole in the theory that only complainers/people with problems bother to do product reviews online. If someone loves a product, positive user reviews will far outweigh negative reviews.
Now, moving to the CNET user rating of 4.4 out of 10 with 50 reviewers. However unscientific, those user reviews reflect the fact that people are unhappy with the HR20. Not that someone "stacked the deck" against D*. Face it, if the HR20 worked as it should, there wold still be a smattering of negative reviews/opinions on feedback sites, but the wouldn't be the majority view.
On the Amazon Etymotic reviews, a tiny percentage of people said the headphones stunk, and sent them back. But the vast majority of people, including me, gave the product 5 stars. If the HR20 worked reliably for me from the start, I would have done the same for it.
User reviews certainly can have extreme views, but on balance, they do reflect the overall user experience. Logic tells you that.
There is no way 175 Etymotic "plants" bothered to send in reviews to tip the scales to the positive. No, that product is a good one, and people will report the good just as well as the bad. It happens again and again. Check the Panasonic plasma reviews, or the Shure E2C reviews. On balance, both get 4 out of 5 stars, with the Shures have 250 user reviews. Why? Because both are darn good products.
If you check user reviews against products, I'd wager that a positive review will jibe with the product's professional reviews as well, in most cases.
Not always on CNET, because their reviews are also based on a single person's experience. If you look at the difference between CNET's reviews and user reviews, there is often a ratings gap.
Overall, there is validity to user reviews. And that's the case with the HR20 as well. Same with Circuit City's user feedback. The extreme opinions reflect the experience of the users, just as they do on this board.
Having said that, D*'s official response was nothing but pathetic PR spin. Just admit there is a problem for an unacceptable number of users, and solve it. That's all anyone who has reviewed the HR20 negatively asks, with the few exceptions of those who want their Tivos.
