Query: AWESOME SOUND ISOLATION

I FEEL BAD GIVING THESE A RATING OF 4 STARS BECAUSE THE SOUND ISOLATION IS JUST AMAZING.YOU DONT HEAR ANYTHING WITH THESE IN YOUR EARS.I ALSO HAVE THE ULTIMATE EARS SUPER FI.5 PRO AND THE SUPER FI.EB.NEITHER CAN MATCH THE NOISE BLOCKING THAT THESE DO,YOU HAVE TO HEAR IT TO BELIEVE IT.THE REASON I CANT GIVE THEM A PERFECT RATING IS THAT THEY SOUND SO-SO COMPARED TO THE OTHER BRANDS.THEY REALLY LACK IN BASS DEPT AND ARE NOT AS EASY TO DRIVE (VOLUME) AS THE ULTIMATE EARS.I WOULD GLADY SACRIFICE SOME OF THE AMAZING SOUND ISOLATION FOR A BETTER,RICHER SOUND.
