I believe most of this coldness in the B3 is because it lacks sub bass. So with this tips I mentioned it gains some sub bass and overall sound warmth. Looks like a different IEM to me. It's more "fun". And somehow the sound gained some body and musicality. I'm very very happy with this tips
And BTW, I believe if @dukespecial prefer soundstage the VSD3S is better with it's V snapped sound. If he prefers forward voice perception, and consequently louder and more noticeable, I believe the IM70 is better. Overall VSD3S is more versatile, less intrusive and signature fatigating. Having voices upfront and intimate can get tiring after a while. For some people it's too intrusive.
