On a whim, I purchased these after a few buyers claimed they fit Sony WH-CH700N Headphones.There was hardly any trouble installing these pads, and they feel about the same as the factory ones.Noise cancelling also works just as well with these, but make sure you get any pair except the perforated ones, from what reviews say, the holes add breathability, but render the noise cancelling feature pointless.For a fraction of the cost of official Sony replacements (just one pad for this model costs over $40 now), my headphones feel good as new.
