You just gotta aggregate multiple reviews by going through different reviewers and mediums. Each is going to have their own preferences, and the only way to get a general conscience is to just see what they say in common. Andrew from headphones show/Resolve Audio, Crinacle, and DMS are some of the few I would give a watch on YouTube.

People like DankPods are just entertainers talking about their hobbies. Valour is just like MKBHD of headphones; just good cinematics but very subjective. Zeos.... I think he also is just an entertainer, but I can't bear anything from that guy due to hella creepy Moe wallpaper he keeps flashing on the monitor. Like half of them are unnecessarily horny and some are just straight up Loli stuff.
