After purchasing the Beyerdynamic DT 770 PRO, I discovered the Superlux HD 662 EVO on this website and decided to buy them for $38 to see how they would compare. I was pleasantly surprised by the significant difference in quality, considering the Superlux headphones were almost five times cheaper. This experience led me to return the Beyerdynamic headphones and approach overpriced headphone reviews with more skepticism.
