EarSonics has always tuned for musicality by combining enhanced bass with great technical performance. Within that framework, they switched a year or two ago from warm, thick tunings to more 'exciting' U-shaped signatures. The EM10 is a pretty big break from their previous models. Technical performance is not on the foreground anymore; the separation, imaging, and resolution. It's not bad per se, but the image is not ultra clean so to speak. But the sound is really very beautiful, as well as smooth. So as much as I love high resolved, clean sounds like the ES80, Samba, A18 etc., the EM10 is becoming a personal favourite of mine. High performance sounds great; but simply good sound, well, also sounds great. I think the EM10's tone is something very special.
