no problem. i wasn't hating on people striving for flat response, i was just saying that it's kind of a will-o'-the-wisp ghostly idea that doesn't mean a lot when it comes to what you hear. our ears aren't the same, our sound processing isn't the same. there is no objective measure that will serve us all equally. so yes, get the specs. and yes, look at the response curve. but don't get carried away with the numbers. their significance and utility is limited.
100% spot on. We don't all have the same internal frequency response. Go by your ears. There's a reason the most lauded headphones tend to have some coloration to them: we like it.
There's a reason studio monitors are considered a separate entity from "listening" headphones as well.
