Just got a pair of 325is and 325e. I've only put some temp scotch tape on the 325e and holy screw. I played Pearl Jam's Alive (You know that intro when the Bass kicks in)

I could hear REAL sub bass compared to control bass . I'll post more details and pics later but initial impressions are great.

I know what you mean. The difference is night and day. Whoever says Grado cannot produce bass should just do this simple trick.

Even though I generally like bass, i found the bass produced with this mod is a bit too "dirty" and have since reverted back to the original pad.

Oh, I really was impressed by the change of this mod. But after a while I noticed a cuppy sound in the mids and a muddiness in the baritone voices, which became too chesty. It's a no go for the ms1. Today I will try the cable velcro straps mod, a more easy and less invasive way to contain the bass inside the cup.

What is this velcro straps mod you are referring to? Link?

It's all about trail and error to get the right sound. I initially had tape all around the foam and it was too much. The mids and highs did take a hit so I then I experimented on how far around the tape should go until I got the sound I was looking for. Pic 2 shows the gap left untouched.

Now the bass if perfect (for me). Basslines are lush and thick, I can "feel" the kickdrums now all without sacrificing mids and highs. It would have been too muddy and bassy if I went all around with the silicone.

Absolutely love these headphones more than models that cost 3 to 4 times more. This mod is on the 325e, so your model may act differently.
