Ultimately I think a frequency response is a good place to start but actual listening should be the final decision point.
If you enjoy the sound of a particular headphone but it doesn't measure well, so what?
Exactly BECAUSE everyone has different ears and taste is why you need objectivity. Since someone used to a bright signature will report a neutral pair as 'warm' or 'bassy', you can never be sure unless a well-plotted graph shows you.
And of course listening should be your ultimate decider, but often people from, let's say, luckier countries in terms of opportunities to try gear forget that in the Old Continent it's more complicated. To give an example, there is only one store in Lisbon selling anything from Grado, and I doubt there are any outside the capital. So for those who can't try gear, which are a lot, they are left with 2 choices: believe in subjective impressions or in objective measurements. I read a lot of reviews with lots of prose, but give it the weight it deserves.
