I know there is a few such thread and I have read them thoroughly...

and have also tested both the cans

and know first hand that

880 = neutral good mid, not so good high and low, and bass doesnt have that wide feeling

990 = good high good low, not so good mid, bass have that wide feeling

have been considering for 2 months and have been going to the shop to test for more than 10 times.....

very difficult to decide would like to hear some opinion and advise from long time users

bottom is.....

i quite like 990 with the wide open bass feel... but the highs are a bit too strong and mid is not good

on the 880 i like the mid and high but the low just doesnt have that wide open sound that I am looking for like in the 990

they are not cheap cans, that's why I have been considering for so long....

- What type of usage (movies and music)
- Genre of music you listen to (almost everything but mainly OST,classical, jazz and your usual songs, power ballad, not so much on hip hop or rapping sort of stuff)
