These pads fit perfect on Ananda Stealth V2, no problems installing or removing. The build quality is excellent, very soft quality materials (Suede, leather hybrid). I dont know how long they will last but I think you will get your money's worth. As for the sound, imaging, depth, separation etc is all there like the originals but it has a softer/smoother treble response with midrange (vocals) pushed forward slightly. Bass is all very much present, about equal with the original pads. The tonality reminds very much of my Sennheiser HD600 but with all the benefits of Hifiman planar headphones, such as bass response, fast transients, separation, soundstage, imaging etc. Overall, im very pleased and for the price, I would be shocked if these could be beaten 10/10!
