Ok, so I got the Sensorcom tips by mail today.
I have to say they fit better then the original bi-flange that Earsonic provided, that's just my personal opinion of course.
At first these Sensorcom tips pop out my ears (I had the same with the Earsonics bi-flange tips). Strange thing is, just as the Earsonics bi-flange tips, the tips in my left ear pops out way faster. Now I took a pair of scissors and cut a part off (tube of the nostrils?). After that I still have difficulties, basically jamming them into my ears untill they will fit. However, this also hurts my ears. They now have slide a bit more back from the core of my ear canal and the sound has become better. I will look if they remain 'unpopped' and if my ears will stop hurting.
If someone has any suggestions/ experiences with above and what worked for you, please do tell me. If what I've done now doesn't work I might try to put them in hot water or in the worst case, order another set of tips. Are there any good normal tips (not bi-flangle) for this in-ears? I'd rather not take a minute for each time I want to put them into my ears.
About the xx GB discussion, I think more then 32GB isn't that strange if you have your music in Apple losless files or FLAC. I first had everything in the standard AAC format from iTunes and could put all my music on my iPod Touch (32 GB). Now when I re-imported all my CDs (Apple Losless files) onto the computer I could only put half of the albums at my iPod Touch.
PS: If you think your Earsonics SM3 sound really weird with your mp3/mp4 players and you have a protection case on it it might be that there is no good fit from the 3.5 mm plug with your mp3/mp4 player. This was my problem with my iPod Touch case.
Edit: Here are some pictures, maybe it helps for better advice?
