I suspect you might need to resend for a refit base on what you mention.
1) The fit for me is very tight and it will not move even if I head bang. It goes so deep that I actually chop off some as I felt its too deep into the canal.
2) The bass should increase drastically, the mid bass being much pronounce.
3) It becomes very detail not because the sound becomes thinner but because the sound becomes more full and vocal more intimate like Diana whispering next to my ear feeling..
4) Vocal become more chesty
