I agree about pro&#x2F;niche reviewers. A few sites I&#x27;ve used: dpreview.com (cameras, though owned by Amazon now, I think), rtings.com (TVs, and they&#x27;re adding headphones), and sleeplikethedead.com (mattresses). I am sure they have their biases, but they&#x27;re good places to start. (And you learn a lot about what the various features&#x2F;materials&#x2F;buzzwords actually mean.)
