Hmmm I just had a look in the mirror with these things on and noticed that my left ear I can't get the whole iem in my ear, e.g. you can see the corner of the blue bit (not the black plate). It's the same with the right ear, but not to the extent. In the photos I have seen, you can't see the iem bit (only the plate)

Of course I still get a good seal, but wondering if there is a problem, as they are meant to dissapear in the ear?
Ok here is a photo of my right ear (which I'm happy with, you can see a tiny bit of red):

now onto the left (I have a blue iem, so it's hard to see, but try dragging and highlighting the image lol) but you can see at the top that it does stick out quite a bit.

Not to sure if the impressions are anything to do with this or do they only account for the canal? Because obviously the livewires fit my canal perfectly, but they just don't seem to fit the outer circle of my ear. I do have quite big ears, but the actual part before the canal is very small (so I'm not sure if the impressions are taken for that bit of the ear too?) and they are just too big for me.
