i got the e5 with the silicon tips, size: small

the right one fits good, the left one not, left ear-canal is smaller than the right one

now i want the black foam tips but i dont know wich size to buy?
and do i get more bass with foam?

i also got the sennh cx400, they sound like the akg k81

Yes foam is bassier, as long as you get a good seal. I find the grey siliocne my favourite, I find the foam too bassy.
(I havent tried the new black foams)

every time i have come away from listening to my e5c's for more than a week, it has taken me another week to get re-acclimatised to their sound. my advice would be that it will take you a while to get used to the sound, and to get the best fit (and hit the sweet spot, and thats always a nice moment). i have had mine for nearly 3 years, and have no desire to upgrade.
yet.
