Who's Amir?
He's just a guy. Maybe knowledgeable, maybe he has an agenda. He may have a YouTube channel ... I have too. Why trust the opinion of just one guy? Look broader. What do other reviews say? I bet there are more? Are they positive? If a majority is so-so then I'd have my doubts ... if almost everyone likes the product it'll be fine. Thoughts on build quality, components used, functionality, specifications, measurements ... those can be objective but if it comes down to how a products sounds it's only my own ears I'd trust.
