Thanks for this. I've been meaning to weigh mine and this post prompted me to do so. My 2016 aluminum LCD-2F weighs in at 625g - albeit with extended yokes and a Lohb strap (although I doubt those add too much to the weight). By comparison my ZMF Atticus - which I always thought was meant to be heavier - actually weights 555g. I can feel the difference on my head between the two, but glad to report that with the Lohb strap, the LCD-2 is comfortable for long listening sessions without any fatigue. If anything the lambskin pads on the LCD-2 are the softest and nicest I've ever owned, and make wearing them a pleasure. The Atticus's Ori pads (also lambskin) are also very comfortable but a bit warmer on the ear.
