@pearljam50000, honestly diminishing returns for headphones hit so much earlier than this. after a very nice $200 mid open set, you won't never get double the sound quality for double your money. as you move up the price bracket, the sonic differences become more and more subtle. first you have to determine what price bracket provides improvements that is worth it for you. then really best way to judge imo is to compare different offerings at that same price point (along with some above & below). there are a lot of headphones that are overpriced compared to competition for their sound quality.
the people here interested in this are usually people who just want as close to perfection as possible and don't care about the money or performance:value ratio anymore.
this... but yes, there are some headphones you can tell are technically inferior performance-wise. personal preference though is more important.
