Thought I'd carry this over for posterity sake given how widespread and easily obtainable these are. Previously posted this on changstar and still use these as my daily driver headphone when I'm out and don't feel like using IEMs, haven't felt the need to upgrade which is usually a good sign for me. My original stock MDR-V6 description: Tried some minor mods because bored: Did some more mods and fine tuning, this is its current form: "Put a sheet of the paper towel (Bounty) underneath the yellow creatology foam and ended up actually using 2 other sheets for a total of 3 layers. The gray acoustic foam I am using is half the width of the one in the second picture. Really smoothed out the peaky highs without causing the mids to become recessed, which is what I was afraid of. The tonal balance of the MDR-V6 is much better now and I've been listening to it all night. I was tempted to buy the massdrop AKG K553 but I am happy with what the MDR-V6 offers now. The drivers in the MDR-V6 are pretty fast and the bass has good impact with the creatology foam in. The mids pretty neutral, they aren't recessed or too forward. I am still using the HM5 pads on them. To be honest, I'm actually quite impressed with them now. It seems the drivers are not being used to their full potential and I'm sure there is even more we can squeeze from them. They're still on my head and I haven't been tempted to reach for my HD800, K7XX, DT880, or Blackwoods."
