I ordered headphones from Amazon that had good reviews, over 1k. I was looking for a cheap pair to listen to music at work. What I got were really poorly made Chinese rip-offs of Sony. I went to process the return and all of the review except for a handful of 1 star reviews had been removed. Luckily the return went off with a hitch but it seems clear Amazon is at least trying to do something, even if their efforts are not sufficient.
