what you will find is that bass is different from bass.
I was actually listening to my BE's and stopped by a friend's house (who has the solo HD).
So I said, hmm. Let's listen to these beats shall we?
I couldn't keep them on for more than 30 seconds. So I had to judge them with different songs in 30 second intervals. The quality of sound has that much of a drastic difference.
But since you're more interested in the bass, you'll realize that the beats do not extend low and do not have the same quality as the BE's.
The beats will also sound artificial.
Those are my thoughts come from BE to solo HD. Not sure how you'd feel in the opposite direction, but whatever you do, don't just jump to the conclusion that the BE's aren't for you because the sound is different than you are used to.
