I doubt the V-Moda 100m have more bass then the DT990, maybe the V-Moda offers a more quality bass.
Unless i need to block outside noise, i prefer the DT990 to the DT770.
Normally open headphones have less bass then closed headphones, but the DT990 is kind of the exception to that rule.
Do you use that bass boost on the FiiO E11?
Do you plug the E11 directly into a motherboard's on-board audio jack?
The E11 is on setting number two, also on high gain and the switch underneath the battery is set to high as well. E11 is plugged into my motherboard yes.
What I am mainly after is I guess called sub bass? I want explosions to really feel like explosions, right now they feel kind of flat.
