That's one of the reasons. I don't like his style but even more important is I own or have reviewed several headphones he made a video of and I just can not agree with his findings at all. Of course I haven't watched all his videos, so I'm sure I would agree with some of them but just can't place him under the "to be trusted to buy" category. sorry :)
I disagree with your reasoning, though you are entitled to have it. We are all individuals, we will disagree every once in a while. For example the T90 weren't the only headphones I bought partly based on his review. Another one was the Beyerdynamic Custom One Pro, I didn't like these, I disagree that they sounded close to the Audio-Technica ATH-M50. So I wound up returning them, but I don't think I can justly say I don't trust him because of that. I've never agreed 100% on every review from anyone before.
