ROFL - you do realize you don't HAVE to put the whole earpiece in your ear canal, right?
Only the tip needs to go in there, AND you CAN select a tip of the right size to fit it to your ear, you know.
There have been a few people I have talked to that have very small canals that have issues getting a small enough tips (my mother being one of them).
Some even have had issues getting custom earpieces to fit.
The only "laws of Physics" would be due to the weight of the earpieces. As I said above, selecting appropriate sized tip addresses lack of stretchy rubber ear canals in humans,,,heh, that was funny. and yes silly of you...
So now you are saying you tried them and know this form experience?
If so, then I retract me earlier statement, if not then you are still making guesses with something you have no first hand experience with.
I have tried both K10u and Roxanne Uni several times and did not feel either of them was less comfortable than the other. it should be noted that this was only for short auditions as I did not buy either of them. I find the custom fit Roxanne and UE7s I own to be much more comfortable than any of the universals that I have tried.
But enough of that, Anyone have any more impressions on the aftermarket cables to share?
