I want to know what he uses to clean his seed off his headphone! I do like his commitment though, and I think it's some good entertainment that he's aware of creating I'd say. I really haven't seen his other vids, but it was entertaining. Amir's review is not invalid, I think the only thing not touched upon was the diminishing of the treble peaks with worn-in pads, which is significant, but not the best way to ship a headphone (needing to burn in the pads with use to diminish the "ear splitting" peaks)....but that's not part of the review because it's measured as a new headphone. It does make a big difference according to the Oratory graphs, so we can concede that.....the issue then remains of the bass that doesn't like to be EQ'd up, at least at loud listening levels. Twas a funny video though.....there's worse headphones in the world.
EDIT: he did talk a lot of rubbish, like he didn't know what the Target Curve was, saying it was "some bullshit he made up", something along those lines.....well it is indeed the Harman Curve, but Amir doesn't like to call it that, but has just as much right to call it the Harman Curve as the likes of Oratory....a few technical reasons why this is the case (it's the same kit being used fundamentally between them). He also said this was a major headphone testing site & why has he only just tested the DT990 now.....well it's not a major headphone testing website, only since the last few months. A few false accusations there.
