It is intentional, and I think ur right, it doesn't sound good. It's a layer i put on top of the bass, to give it more power on smaller boxes like a laptop or headphones, cause before, you just didn't feel the bass sound if u listened to it with phones... But i'll delete that layer inmediately, as it fucks up my bass sound... But this question remains, how to make sure your bassline punches through on phones or small boxes without a sub?
