rusnak666,I have both DT1770PRO and DT1990PRO, and am completely agree with kman1211's impressions.the bass of 1770 hit harder than that of 1990 because they are closed back, but if you carefully listen to the sound you'll find bass of 1990 extends little deeper and has more detailed texture. So this is the matter of preference. if you like bass slam you should go to 1770, and if you want bass precision I recommend you to go to 1990. me? I love both.
