If there's one knock against the Audio Technica ATH-M50x's it's that they can really clamp down on your noggin. Some blame it on the earpads but I think it's just the sheer force on the side of your head. I could feel significant pressure on the side of my face and upper jaw. Not pain so much as just noticeable pressure. I've been stretching the headband to help alleviate but it didn't help enough and I didn't want to stretch it out too much. This brought me to search and find the Brainwavz earpads. I had seen reviews from other M50x owners and knew they'd at least fit. I felt the larger size and memory foam would make up the difference. My only real concern was from owners that said they changed the sound of their headphones. I've seen reviews from some people who swear by it and others who said it didn't make a difference. Now I have them on and can definitely say there's a difference. They not only feel good but actually sound better! The pressure isn't 100% gone but is significantly better. I don't notice it the same way I did with the original pads and can keep them on much longer without being reminded of them. I knew they'd feel good from the moment I took them out of the package. Talk about soft! The leather and the feel of squeezing the memory foam inspire confidence that you're in for a treat when these get around your ears. They really get around them too. At least around mine. No part of my ear is touching the pads. Getting them on was easy too. Taking off the old pads gives a good idea of how to put the new ones on. I started from the top by placing the edge of the pad in the ridge around the speaker then inserted the rest by placing my fingers inside the pad and stretching it over the ridge in a circle, working my way back to the top. It was pretty easy on the first try. Sound wise, as I said, I think they sound better. I was a little worried that once I attached these nice pads, that the great sound I was used to would change. I had some tracks picked out that had nice clarity and bass and I didn't notice a drop in either. If anything, they sound more spacious. I guess that's the "soundstage" I always hear about in reviews. It somehow sounds larger, possibly due to the fact that there's now more space around my ears. That's a nice bonus. I'd have been just as happy if there were no change at all. Overall, I found these to be a worthwhile investment. My headphones that had a strike against them are now perfect and now have a more premium look and feel. Speaking of looks, the brown is a fine match for my limited edition green and brown M50x's and is nearly indistinguishable in lower lighting. Another nice bonus. I'd definitely recommend these to anyone looking for a more comfortable feel from their headphones. It's a premium feature usually found on more expensive headphones but at an affordable price. Highly recommended.
