Maybe.
There are people who hate anything. You could probably find 17 year old boys who hate sex on the internet, with a little searching. People who hate can be very vocal. Watch Sony camera fanboys shred products with features/issues they defend on Sony products, for example.
You have to read reviews with a critical eye. If everyone is complaining that the headphones are too heavy, but you are more interested in their extended battery life, well batteries add weight. If people say they are too small, but you have small ears, then maybe that's a match.
On the other hand, if they break all the time, there may be a real issue. I don't generally trust BRAND over product reviews, but I do not trust product reviews alone, either.
Apple, Nikon, and LG have earned a bit of goodwill from me by releasing products that just keep on working the way I want them to for as long as I care to use them. I am less kind to Sony, Chrysler, and Samsung for their less sterling track records.
