i haven't even touched my HD800's since I got them! lol It's just because they're new though.
I'll look into lawton modding them but having to ship them to the US will be likely 60$ each way plus the actual mod. I'm going to order the earpads regardless as they look much better but I'll see what they have to say, I emailed them a few mins ago.
I find the phones go into muddy bass with games more than music, to be fair, my 800's do the same thing, just sounds a bit different. I get my hearing tested at work every year and for the past 11 years, it hasn't changed any, I'm in the top 2% for hearing, so it's excellent as of now. lol
