[LAU] ot: maybe, headphone search site?

[Karen Lewellen]

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,
