Hy guys! I want to buy some CIEM like portable headphone in every day life and like monitor when I play drums (concert). I really enjoy my LCD2, the sound on percussion and drums is really natural and true to my ears and my taste. I want a CIEM in this spirit of sound signature with a price under 600$. I find this 2 CIEM's : - AS-1 Digital-Hybrid Custom - 1964-Q And i don't know which one to choose... If someone can help me to choose between this two products and tell me the difference between each CIEM, it would be perfect! Thanks! Ps: sorry for my poor english level, maybe a french curse!
