Yea but it's a difference between punchiness and constant low-hum... my point was the difference between them in impact.
Check this classic trance track for example:
At the beginning you hear mostly the midbass, the "thump", while it's filled out a little with subbass to sound fullier but without the thump this beat would be a soft humming without much impact. On Beats headphones for example, this "thumping" will feel more like a hammer is hitting you with every beat, while on DT770 it will have a much softer impact. There's a chance the OP enjoys this "hammer-to-the-head" punchy bass impact. :P
Just thinking logically here, OP comes from Beats to DT770 and isn't satisfied with bass. Beats are a very midbass focused headphone with punchy bass, DT770 is more a rumbly but softer bass. The difference in subbass shouldn't be all that big in them (the DT770 also have better extension as Beats rolls off quickly & heavily after 30Hz) but there is a big difference between midbass in them => OP probably wants more midbass. I've never personally had great experience with trying to EQ up the midbass either, subbass works better to increase EQ-wise than midbass, the end result is usually worse when trying to boost midbass versus subbass as it will mostly add audible frequencies but it won't necessarily increase the physical impact with the "thumping", at least that's my experience so if you enjoy that punchy bass you're better off to buy a headphone that offers punchy bass to begin with. XB800 for example offers extremely punchy bass it seems, others are for example V-Moda LP/LP2, Ultrasone Pro900, M-Audio Q40, Audio Technica Pro700MK2 and I guess Sennheiser HD25-II (quantity wise not THAT bassy but extremely punchy bass for the quantity it packs, I've tried them myself and can confirm this)
For many years ago I also came from a Sennheiser HD212 pro to a DT770 pro/80 and was also disappointed with DT770's bass and later on I can now say when I got more knowledge is that it was due to the lack of midbass on DT770. Don't get me wrong though, the Tanks in for example Unreal Tournament 3 shook my head like never before from the low-humming engine noise with the DT770, the subbass was stronger but the midbass was noticably less present so it lacked punchiness.
