Forgot that you won the ES5's!
I had a chance to check them out. Now obviously I am comparing the modified universal version of the ES5 to what I heard universal wise with the 16/3a, 13, and 16, but generally speaking, the overall sound signature of the ES5 appeared to be tilted more towards the top, with a slightly thinner character in the lower mids and bass, whereas the JH's were definitely fuller yet still retained nice detail and sparkle. The ES5 top end I would say sounded more present but to my ears just a tad bit of etch came into play. This using my ipod into slim. Its leagues beyond my se530's and I am sure the custom one would sound better, as I heard an anomaly here or there with the universal versions of the JH's. If I won ES5's I would be happy
