Still kicking even its today standards. I was forgotten this good sounding headphone. I did not found the original pads but I got some China real memory hybrid pads. Measures quite good and sounds too. Natural sounding, very open'ish, clean and a bit too light on the bass dynamics. Very light and super comfy headphone. Best for vocals and acoustic.
Here is my measurements. I use 105mm soft memory cushions. Only mod I did I taped the front of the driver with kinesio tape.
110mm givest a bit more bass and measures a bit different. That measurement was done with the HD688. Also bigger is more comfy. But not a big deal because this very light headphone with very loose pressure.
My measurements are quite same with those non memory foams. I'm looking also soft memory foam cushions to my new Takstar HF580. Most memory foams are a bit too dense. I'm getting too much middle section.
I can do more search if I can find something on my buy history. I'll update this post if I find something.
And it was memory foam. Mine memory foams 105 and 110 feels the same and looks too.
