Is there such thing as burn in for IEM? I swear mine is getting better with hours (>10) of playing. Hate the sound at first but now it really shines. Better bass and treble become acceptable. Done some tip rolling and I settle with spinfit. Happy with the purchase.
I've had mine since the first drop, and I think they continue to get better for a long time. They are definitely exceptional. I was able to get a second cable and terminate it with a Neutrik balanced connector to be able to listen to my Jotenheim, and they are absolutely spectacular in that setup. Huge improvement in many ways over any of the single pole listening I've done. I love that they can sound in my mind demonstrably different as you use better sources, or connections in my case. Love mine.
