-angled
-spacious
-large
-GLORIOUSLY SOFT
Been soo long sice i've used stock pads, cannot give changes to sound, will say though, it is a blessing from NVX for its comfort.
I recommend putting flap OVER the silver, fits snuggly like that. if you put in the cut-out for the flap it will be loose, but still fits. although it's also much harder to get it in there.

-not angled
-slightly less spacious
-not breathable (sweating &or hot for long periods of time)
-seal significantly better
Gotta stretch them a bit to get them on, but they weill fit. Take your time getting them on the first time.
These i can say for certain, seal in the low end. Sooo much bass. These were the first replacement pads i've gotten for these. I use interchangeably.
They're gel, so they are still incredibly soft, but in a different way. but also do not breath what so ever.
If you open up the cups and put in a couple layers of high and low density foam in the cups... well these things will become hearing protection. (gun range's 'safety manager' approved with a "Holy ****, yea those block out sound. They're good to go.") Better then ear plugs OR over-ear hearing protection, Almost as good as both of them combined.
