I was worried that getting these for my HD58X’s would change the sound significantly and that the quality wouldn’t be as good as stock, but I’m instead blown away by the quality, fit and finish.
These are supremely comfortable, and they’re cooler than the stock pads too. They do change the sound - but only in so much as there seems to be a little more separation from my ear to the driver, so there’s a tiny bit more soundstage. I can’t really hear any difference in tuning.
Overall I’m very happy, will be buying more for my Sundaras next.
