Ditto - I find that for me these work best not with a tight seal but placed fairly gently in. Deeper in and the low notes become bloomy. In this respect the very opposite of what I'm used to. I completely agree with the above comments about non-fatiguing musicality vs up-close analytical detail.
That's exactly my experience! I have to use these almost like ear-buds, gently in my ear, shallow rather than deep fit.
