Enjoying them a great deal - today I have turned the volume down and like them better. When they first arrived, I listened loud... because I could - but at normal listening volumes.. actually really low - the details are all there. As for isolation - I have never had an IEM cut me off from the world like these. With anything I have owned, if the music was off I could hear what was going on - now I can have my daughter stand in front of me and I have to watch her lips to understand her. If she turns her head, I am screwed - I have to pull one out to have a conversation. The comfort is unlike anything I have tried before. They aren't there. The lower sound floor makes low volume listening more enjoyable, whereas before - with any other IEM I've owned (BA or Dynamic), I have used to volume control to drown out outside noises.
I guess I got lucky with fit - When I first got them (They were an ownership transfer) I stuck the 8A's in my ears to try to get a listen - the right side sealed, but at a price - it hurt like hell. I could imagine what the wrong fit would feel like - but these simply disappear into my ears - one tug on my earlobe and they suck right in.
...oh and another thing - When UPS delivered these, there was no signature required and there was no customs charges whatsoever. I know that they only valued it at $170 while they insured it for $1,600 or so. Not happy that they would have left them on the porch if no one was home - lol.
