Review on Brainwavz ProStock ATH M50X Upgraded Earpads, Improves Comfort & Style Without Changing The Sound - Ear Pad Designed For ATH-M50X M50BTX M20X M30X M40X Headphones, Vegan Leather (Black) by Aaron Gordon

Super comfortable replacement to the stock pads on the Yamaha HPH-MT5's (I think they also fit their more recent version, cannot recall the model name but it starts with HPH as well). The padding is substantially more robust and comfortable than the stock pads, and it is thicker as well (your ears don't hit the walls anymore).I bought mine directly through Brainwavz, I wish I had checked ebay first so I could have saved on some shipping- but it was well worth it. On the note of worth it, go for the sheepskin leather- for one it shouldn't break down like the polymer pads eventually will; and they also feel much better on the skin.Fitting them is easy (writeup for the Yamaha HPH-MT5 only):1) Remove old pads, they just pull off at the corners.2) Place new pad over a corner or a face.3) Get small ruler or credit card.4) Use ruler/card to push material into place as you work your way around the headphone. You will need to hold where you started in place for a bit until the material can "catch".5) Once you have the whole pad seated, go around and try to "stuff" the material in the recess where the old pad hung onto. This is something I didn't do right away and one of my pads came off when I was putting the headphones on.The sheepskin leather is plenty tough, it'll mar/scratch before it tears. Just take your time and go slowly. I am sure they have videos online to help with this- but it seemed straightforward enough.Hope this helps fellow MT5 users out there!
