Some might find it bass light. I find it quick and decent quantity. I wouldn't mind if it had a little more. This is where the mod dsnuts posted helps and also if there were thicker/better pads would also help.
It does add some weight and is bulkier but the bulk is below the Y-split so I doesn't pull the earphones out of your ears. Definitely wouldn't jog with them though. I can go for walks without issue. Here a couple of pics so you have a better idea.
