Funny how we all prefer different sound signatures. Not sure if L2P has different bass than L2, but with my L2, I prefer the Bass Boost EQ. Otherwise, I just find the bass lacking. Possibly I am not getting the best sealing against my ear canals, but I've tried all the different tips they came with, and still find the bass lacking unless I boost it. And with Bass Boost EQ in place, treble also feels reduced, which I like.
