Hey guys, I'm considering upgrading the earpads on my M40X as they irritate my ears and get really hot after long usage. I got my eyes on the HM5 angled pads (ZMF are too expensive) but I'm not sure which one to get, the pleather or hybrid ones. I don't want to mess up the sound too much. Which HM5 pads would you recommend? PS- Also, if anyone recommends the Shure 840 pads. I've heard they are good too.
