Thank you!
Until the Complys get here, I'll keep experimenting...
When I use the tri-flange, should all three flanges be within my ear canal? The furthest I seem to be able to go has the biggest, third flange hanging about halfway outside of my ear, in the "bowl" of my ear, so that only its narrow portion is in the canal.
Should the black "barrels" underneath the slimmer black barrels (over which go the tips) be inside of my ear canal at all? I can't get them to even start going in.
I seem to be able to get the triflanges in further than the foamies. The foamies "open up" again really soon after compressing them, before I can get them far in.
It's hard to tell whether I'm getting a good seal when I'm listening to them without an amp. My onboard sound has a rudimentary amp when you select "headphone out", but I'm sure it's completely insufficient. But basically, if you've done some work in sound editing/effects/music, you know how most compressor software offers a preset "telephone/old-time-radio" filter?, well that's kind of how the ER-4S sound right now. The trebles are pretty clear, but everything from the mid-range down is very "sparse" and "diffuse". It kind of sounds like you're "not really" listening to it - like it's in another room or something.
Not blaming the ER-4S, just describing what a no-amp & possible-bad-seal sounds like. :B
