If anyone is curious, here's some very early impressions of the Q701 with 65th Anniversary pads.
Feel free to tell me i'm wrong or hearing things. I am giving impressions of pads after all...
Out of the plastic there was a tiny increase in mid-bass, but it was basically almost the same(!!). We're talking like a 3% difference (if I had to put it into a percentage). Low bass between the Q701 and 65th was mostly the same, but a barely audible improvement with 65th pads.
So for ME the Q701 with 65th pads needs the outer grill foam removed. It's easy to remove. Use a piece of tape (make it less sticky with your fingers if needed) and turn counter-clockwise. Don't use metal objects!
NOTE: The Q701 doesn't have a lot of clamp at all for me. It's very secure, but most people with bigger heads may possibly get more bass.
So...the Q701 with 65th pads and no outer grill foam is sounding pretty good! Doesn't really seem that much warmer though...yet.
Probably not worth the $73 unless the Q701 is your favorite headphone in the world and you want a little more bass without using an EQ.
Theres still some very low bass that's not audible at all on my Q701. So if you didn't hear it on the Q701 with stock pads, the 65th would change that much.
