HDJ-X7 HDJ-X5 HDJ-X10 Replacement Ear Pads Compatible with Pioneer HDJ X7 HDJ X5 HDJ X10 DJ Headphones Premium Velour Cover & Memory Foam for Enhanced Comfort & Sound Quality

Beat the original pads by big margin in term of comfort. The foam is soft and reasonably breathable. The thickness is just right to be put into the original carrying box. However, the thickness is not so different from the original, like one of the listing photos shows. I don't think it changes the sound quality so much. I did hear a very slight deeper bass and tremble airiness, but that may not because of the pads, but because of the slight change of distance from the ear to the driver, due to the different thickness.

Fit al little big on one side. I think it may be defective because one side fits perfect. Sound is altered with these but still sound ok.
