I do not know the tech difference is, but one of the forums said it was a shorter chord, and a ridiculous amount of bass. kind of a stupid mod, shortening the cord, but whatever.

I dont think adding foam is the kramer mod.. I thought it was piercing the paper diaphragm to allow for a bit less bass, and more high end sparkle.

Some of the differences include a shorter cord and different foam tips. The sound is different(although I won't compare that since I've had my FX-33s longer and they had more time to get "burnt in").

The foam for the FX-33s was longer and more pointy, making deeper insertion easier(similar to a canalphone). All four tips were the same size. The FX-34 includes two larger and two smaller tips. Both of them are more rounded, as to sit on the outer part of the ear canal. The seal is OK, but not as good and not as secure. This mod seems good for the 34 to make the foam tips easier to fit and make a better seal.

thx nickdawg & keith!

I couldn't get a decent seal with either of the stock foam tips with my FX33 & FX66. They are gone now, I never tried the reverse foam.

I finally got to hear some IEMs with flanges I love those. Are there any that fit on the FX33/34 or FX66?

again, taking out the paper diaphragm is part of the mod, and makes it very sibilant and peircing upper mids. adding the foam brings down this peak and brings out the upper treble and smoothes out the mids considerably, as well as removing some more bass.

i dont think kramer would want to be associated with just the paper peircing/removal, as it sounds like crap compared to the very good sounding foam addition.

sucks to hear about the fx34, i better take care of my fx33's now.. which is just weird!

as for the reversal of the foam, i found my tips but they are old and i lost the grey tubing so it is hard to roll them, infact all it does is squish them horizontally / vertically, and doesnt stay compressed. i shove them in my ears and it feels decent but i fear that the ends/opening is compressing and taking away from the sound and treble, which is why i like the clear shure flex tubes because the opening into the ear stays firm.

edit: if i push them in without trying to compress them, they actually end up compressing evenly and don't close the opening as much as wearing them the normal way and sound a lot better upper treble wise than the non reversed way, comparable to the shure flex tubes. but the flex tubes look better! will do more comparing later..

i believe all UE tiips fit, along with shure e2c tips.
