The old HM5 pads or the newer with memory foam?
I just installed the memory foam type on my "storm troopers" and had a cursing time. I wished I had caught that tip about some oil/Vaseline on the edges, but I'd probably would still have have a hard time because it was hard to get a grip. The edges are now frayed, but at least they're on and not that noticeable.
I wasn't initially fond of the pads, but I found that it's much better with some tightly rolled up tissues behind the padding which vastly improved the sound.
Does the original sound far off from the memory foam?
Oil would help the leather stretch.
But I learned somewhere that not all oils (or liquids, waxes, etc) are good for leather as they may contain enzymes which break down the leather fibres.
I'm sure that conditioners for leather specialty shoes (which are expensive) would work well.
I have a damaged T50rp driver. Is there anyone out there who would be willing to sell me a driver (or set)? I'd also be willing to purchase the whole headphone as well. Thanks
