im still learning how to explain all this thing so i may be wrong
Type of Music: Heavy Metal
Soundstage its quite huge.
Cymbals crash not enough the crisp is missing
Bass its nice because i ask for 50% more bass XD
Vocals can feel the emotion really nice!
I think it's most probably a fit issue (quite unlikely your ear will change shape unless there's an inflammation in the inner ear currently). But the choice is yours though I would strongly recommend you to set it back for a refit, since you had already spent quite a sum of money on it. Cheers!
