I have never had the 1.0 or 1.1 so I can't speak to those. I have tried everything lately.
These are by far the best sounding and the fit is so good i can't believe not all iem makers use this design.. it fits like a custom..
the bass packs some crazy punch..
i'm not going to review it like others do since i don't know what half of those adjectives used to describe sound means.. but i do know when something sounds amazing.. not just good.. but dam good
these are now my favorites next to my um3x.. they sound very different.. asg-1 feels further away from my head but packs way more bass punch.. mid and high similar for both
recently i have tried and returned pfe232.. ie80.. w4r.. se535... x10i.. tf10.. atrio m5 mg7.. gr07.. er4p.. yes amazon hates me... lol
