I read the Amazon reviews for any particular headphone. There are a lot of non-audiophiles reviewing there, but most of the time it's easy to weed those out. I start with the one-star reviews and work up to 5-star last. Amazon tries to hide "non-verified" reviews, so you have to find the button to unhide those, and then whatever other button you click, they might hide those again. Anyway, there are enough gems in the Amazon reviews to make it valuable (if the item gets enough reviews), since you don't have to read through hundreds of pages of chat. The 'free' or "Amazon Vine" items are usually identified, but those are a mixed bag too - worth a quick look.
