[LAU] ot: maybe, headphone search site?

Hi everyone, hoping to ask this question without too much confusion. I am seeking a headphone focused site where I can either entre specification details, i. e. frequency range, sensitivity etc., and get headphone options, or that provides all of the specification details themselves. There used to be a place head zone for this years back, is headphones.org still around? because I use many different things in various ways, with the specifications rather the key, my focus is on using this data. Unfortunately because headphones are also a fashion statement these days, getting clear numbers can be a challenge. Any good resources? Thanks,
