I have been doing a lot of listening to the ED16 and ZS10, mostly just with my phone, a Nexus 6p. So, not a great source, but sounds pretty good. Neutralizer affects the ZS10 more than the ED16 on my setup, but post Neutralizer, both of these sound VERY similar. I agree a bit with what you say about the ZS10, as there is something in the sound that is a bit metallic, but I do not get the nasal effect you describe with trumpet, and I am a trumpet player. This is with symphonic music, in this case a couple of recordings of Sibelius symhonies, Berlin Phil, Simon Rattle. To me, the ED16 has a thicker and more real low end. The ZS10 has a better stage, width wise. Depth wise, they are similar. The ZS10 provides more space and 3d to acoustic instruments. I do not find vocals to be more recessed with the ZS10. I still overall slightly prefer the ZS10, as I find my level of enjoyment of the music to be higher. It just gets out of the way of the music for me. I suppose that could cause me to overlook its flaws somewhat more, I do not know. I am using Tennmak wide bores with the ZS10, and the stock KZ medium tips with the ED16.
