It took an incredibly long time for the driver to settle down, I absolutely enjoy using mine.(300+ hours)
Infact I use these whenever I listen to cello solo, nothing I own can bring the same sound for cello like the ES10.
I think the people ordered their ES10 from ebay but they are not cheap. I still do not know the improvement they bring beside the fitting comfort.
