Hi @Onurb8690 , I'm for around 10 years in the CIEM market, I had several different brands and at the end my favourite CIEMs remain EarSonics' products. The EM10 is without a doubt better than the EM64, that's the big sound which surrounds you, whereas the EM64 is a more live approach. I prefer the EM10, I never encountered frustration in listening to music with them, tone is accurate, dynamic takes feelings in, trebles are deliciously harmonics... The EM64 is quicker, smaller, stronger and I like it just to change tastes, after a while I come back to the EM10. Among the SE5 Ultimate, VE8, Phantom, FIBAE7 or other TOTL, the EM10 is technically competent, but emotional and beautiful. A very special and involving tuning.
Sorry for my poor English, morning here... ^^
First of all thanks for your reply, I am quite inclined to move straight to EM10, what did you mean by the "stronger" EM64?
