Replaced on Sennheiser Momentum 2.0 over-ear and Audio Technica ATH-M50x.
These headphone pads are of excellent quality with lovely genuine sheepskin, and they fit both headphones perfectly. They can be a little tricky to put on (especially on the Shennheiser), but take your time and they'll slide right on. The size is big, very big. And I love it! No pressure on the ears at all. Do they affect the sound? Absolutely! The soundstage is much wider than with the original pads, but that's just great. The sub-bass and bass suffer a little with a slight reduction, but a little adjustment of the equaliser fixes that.
