I regard to slowness as bass quality vs quantity disbalance. You know the bass is slow when there is a delay between kick and oomph. It's never been as bad to me on headphones, but on some badly amplified live performances the delay may be up to half a beat. Of course, we're not dealing with bandpass-enclosure-ish bass delays when listening to headphones, but some modest bass slowness may occur when you're pushing low end to more than enough impairing low end definition and coherence.What is slow, how can headphones be slow?
